Polymer lithium battery and lithium battery What is the difference?

The current polymer lithium batteries and lithium batteries are different about the following:

      1. Appearance: As long as the aluminum foil package flexible packaging, probably claiming to be lithium polymer battery. Polymer batteries because there is no metal shell, the advantage is thin. However, the disadvantage is no metal shell protection, vulnerable to external damage.mobile power plant

       2. Safety: As the polymer battery using flexible packaging, and the amount of liquid electrolyte less, if unfortunately the battery problems, the battery will expand, so that poor adhesion between the battery plates and cause the circuit. And if the situation is more serious, the seams will crack and release pressure, there is less danger of explosion fire. The metal shell encapsulated lithium battery although there may be pressure relief port design, but when the pressure or temperature is too high, the risk of explosion fire will be higher.

      (Polymer battery can only say that the design of the mechanism makes it less likely to explode, but in fact the chemical properties can be said to be almost the same, really want to engage in the same small one is also very scary to burn up

     3. Cycle life: Early Ericsson polymer batteries, batteries often see a few months after the apparent expansion, the performance is also an instantaneous decline. As technology advances, the current high-quality polymer battery life also improved a lot, but still inferior to the same level of polymer lithium battery.

     4. Price: In the production technology and cost, the polymer battery is higher than the lithium battery.

       Lithium polymer battery life

       Correct argument: lithium battery life and the number of completion of the charge cycle, and the number of charging is not directly related.

Simple to understand, for example, a piece of lithium on the first day only half of the electricity, and then it is fully charged. If the next day is the case, that is, with half charge, a total of two charge down, this can only be counted as a charge cycle, not two. Therefore, it usually takes several charge cycles to complete one cycle. Each completed a charge cycle, the power will be reduced a little. However, the reduction is very small, high-quality battery after many cycles, still retains 80% of the original power, many lithium-powered products after two or three years still in use, is the reason. Of course, the final lithium battery life needs to be replaced.

Lithium battery life is generally 300 to 500 charge cycles. Assuming that a complete discharge provides a quantity of Q, the lithium battery can provide or supplement 300Q-500Q of electricity for its lifetime, if the charge is not taken into account after each charge cycle. From this we know that if every time you charge with 1/2, you can charge 600-1000 times, if every time you use 1/3, you can charge 900 ~ 1500 times. And so on, if randomly charged, the number of uncertain. In short, no matter how filling, a total of 300 ~ 500Q added to the power of this point is constant. So, we can also understand: lithium battery life and the total charge of the battery charge, and has nothing to do with the number of charges. Deep and deep charge and shallow charge Charge for the impact of lithium life is not much difference.

In fact, superficial charge is more beneficial to lithium battery, only when the product's power module is calibrated for lithium battery, it is necessary to deepen the charge. Therefore, the use of lithium-powered products do not have to rigidly adhere to the process, all for the convenience of the first, always charge, do not have to worry about affecting life expectancy.

Lithium polymer battery

If lithium is used in an environment above the specified operating temperature of 35 ° C or above, the battery's capacity will continue to decrease, ie, the battery's power supply will not be as long as usual. If at this temperature, but also for the device, it will damage the battery more. Even storing the battery in a hotter environment can inevitably cause damage to the battery's quality. Therefore, try to maintain the appropriate operating temperature is to extend the life of lithium a good way.

If you use lithium in a low temperature environment, that is, below 4 ° C, you will also find that the battery life is reduced, and some mobile phone's original lithium battery even in the low temperature environment can not even power. But do not worry too much about this. It's just a temporary condition. Unlike the use of high-temperature environments, once the temperature rises, the molecules in the battery heat up and immediately return to their previous level.

To play the maximum efficiency of lithium-ion battery, you need to use it often, so that the electronics within the lithium battery is always in a state of flow. If you do not often use lithium, be sure to remember to complete a lithium battery per month charging cycle, make a power calibration, deep deep charge once.

The above is a small series to introduce you to the polymer lithium battery and lithium battery difference, hoping to help you.

How long is the cycle life of auto emergency start power?

Whether it is mobile power or start power or battery, everyone cares is how long its useful life, how long? The life of a battery can use it to cycle the number of discharges to measure its life cycle. In order to measure how long a car emergency start-up power battery can be used for such a performance, the definition of the number of cycles is specified. The actual user experience is ever-changing since tests of different conditions are not comparable and cycles must be regulated Life definition.mobile power plant

GB requirements for emergency start-up cycle battery life test conditions and requirements: 25 degrees at room temperature constant current constant voltage mode 1C charging system charge 150 minutes to a constant current discharge of 1C discharge system to 2.75V deadline for a cycle When a discharge time of less than 36 minutes when the end of the experiment, the number of cycles must be greater than 300 times.

Explanation:

A. This definition provides that the test of cycle life is carried out in deep and deep way.

B. The provisions of the cycle life in accordance with this model must be performed after more than 300 times the capacity is still more than 60%.

Another measure of cycle life is the time. Some experts pointed out that in the case of automotive emergency start-up batteries often put forward the general automotive emergency start power battery life is 2 to 3 years, with the actual situation, such as 60% of capacity for the termination of life expectancy, coupled with the car emergency start The aging effect of the power battery, and then not everyone has its own professional knowledge, so popular point, a car emergency power cycle life expectancy is generally 2-3 years. Therefore, users do not have to worry about their own power supply life is too short to buy the problem.

Car emergency start power loss when charging it?

Car emergency start-up power loss when charging it? This problem may be that many people use automotive emergency start-up power have a problem in my heart, the answer to this question Yes. For example, we use 4000mAh capacity car emergency start-up power to charge the phone, its power can not all reach the cell phone battery, because the use of electronic products in the process of battery loss is a normal phenomenon , So the car emergency start power battery loss in the charging process is inevitable, it mainly exists in the following aspects of the loss:

Car emergency start power loss when charging it?

1, power loss.

Auto Emergency Start Power When charging a mobile phone, it charges more than just the battery, it also needs to power the other parts of the phone, so this is one of the losses that a car's emergency start-up power source charges the phone.

2, voltage loss.

In general, the automotive emergency start power battery is the use of maintenance-free lead-acid batteries and lithium polymer battery, which lithium polymer battery discharge voltage is not changed, the safe discharge range is 4.2 V-2.7V, so the greater the range of discharge, the loss of its power will be increased accordingly.

3, resistance loss.

We should all know that the car emergency start-up power supply to the phone, are connected through the circuit board and wire. Therefore, there is a conductor in the connection between them, and in the case of a conductor, there is resistance. The main physical property of resistance is the conversion of electric energy into thermal energy. Therefore, the car emergency start the power supply to the phone in the process of charging, the conductor will have heat generated, the heat generated will be quite depleted car emergency start power supply.mobile power plant

4, circuit conversion loss.

Car emergency start power to charge the phone, there will be fever phenomenon. Therefore, according to the law of conservation of energy, the heat emitted by the product itself is actually the energy of the built-in battery, so the circuit switching loss is also a loss of automotive emergency start power supply on the one hand.

The four aspects described above are the most important aspects of automotive emergency start-up power loss in charging, then how should we reduce these losses? We can be in the car emergency start-up power charging process, it is best to do Constant voltage and constant current, as constant voltage and constant current can be output voltage and current stability of the output, so that the car emergency start power supply loss reduction in the standard range, so that you can properly reduce the car emergency start power supply Charged when the loss generated.

In this step, care must be taken not to clip the positive and negative cables together.

5, in the car emergency start power supply process, should be strictly prohibited to make the red cable clip and the black cable clip mutual contact phenomenon. Because if accidentally start the car emergency power cable clamp contact with each other, then there may be burnt copper, burns and other phenomena, the final result of the car emergency start power can not be used normally.

The content described above is the car emergency start power when starting the car should pay attention to five aspects, only we use the process, do more than five aspects, can make the product use to play the maximum effect.

Automotive emergency start power can not start what are the factors?

We should all know that the car emergency start power battery capacity test, are done by a constant current constant voltage battery charge, and then to constant current discharge, the last release of how much power is the capacity of the battery. Then you know the factors that affect the car emergency start power capacity what? Here as a car emergency start power manufacturers to introduce you to:

1, discharge rate.

The capacity of lead-acid batteries decreases with the increase of discharge rate. That is to say, the larger the discharge current, the smaller the capacity of the battery is calculated. Therefore, for a given battery, it discharges at different rates and has different capacities. It is noteworthy that we must know the discharge rate or rate at discharge.mobile power plant

2, temperature. The company is located in:

    Temperature on the automotive emergency start power lead-acid battery capacity greater impact, in general, as the temperature decreases, its capacity will decline.

3, the termination voltage.

When the battery discharges to a certain voltage value, the voltage drops sharply, in fact, the energy obtained is very small, if the long-term deep discharge, the damage to the battery is quite large, so the discharge must be terminated at a certain voltage. The cut-off discharge voltage Called the discharge termination voltage, set the discharge termination voltage, to extend the battery life is significant.

4, the geometric size of the plate.

When the amount of active material is constant, the geometric area of direct contact with the electrolyte plate increases, and the battery capacity of the automobile emergency start power increases. Therefore, the influence of the plate geometry on the battery capacity can not be ignored.

The four aspects of the above description is some of the more common factors that affect the capacity of the battery

Here, we invite Ms. Zhang Jieping, a marketing engineer in power management department from ADI Company, to talk about the market status and development trend of power management chips in detail.

1. In the face of increasingly stringent power efficiency requirements, do you think semiconductor manufacturers can help improve the power conversion efficiency of the power system?mobile power plant

Green energy is the demand in today's industrial chain, to enhance efficiency has become the goal of upstream and downstream manufacturers. Semiconductor manufacturers are striving to improve their devices by, for example, reducing static power consumption and reducing light-load power consumption with new control technologies. They improve overall efficiency by integrating features such as power devices that dynamically regulate output voltage by sensing the system's operating state To achieve the purpose of optimizing the efficiency of the power devices in terms of process improvement to improve efficiency. A variety of enhancements are made due to the concept of green energy to make due efforts.

2. How do you view the current trend of power management technology development, the future power management system how to deal with changes in market demand and harsh requirements?

With the rapid development of 3G technology, the construction of a new generation of base stations and data centers in the financial and telecommunications networks also places higher demands on the power management system. At the same time, large-scale popularization of 3G technology communication networks, increasing concentration and increasing data volume transfer require that power suppliers must increase their investment in innovative technologies and improve their energy-efficient performance. Through the introduction of high value-added products or solutions to save users the investment cost, while ensuring the stability and efficiency of the operation, in order to fully protect the user experience. Green, environmental protection, energy saving has been the focus of power management system technology innovation in recent years. With the continuous infiltration of green technologies in various industries, new industry standards are also driving product upgrades.

Lighting, telecommunications, smart grid, smart appliances and other fields also have huge room for growth, but also the direction of the focus of power companies. Energy-saving is mainly reflected in the energy-saving power products and the overall energy-saving room, and "green" is mainly reflected in improving the efficiency of the machine to reduce the interference to the power grid and save space and save costs.

In addition, the module power, networked power is also the current focus. Modular power supply, in addition to improving the reliability of the power supply, the company itself can also be based on electricity load matching module. Therefore, manufacturers who want to maintain or even increase their market share in the fierce market competition, continuous technology and product innovation is the top priority. For the power industry chain, the development of standardized universal power supply has been quite mature, but efficient, energy saving, miniaturization, high power density is still the focus of a new generation of products. For the power market segments, such as medical, industrial, automotive, energy, consumer, etc., power supply companies will be combined with the system application, the development of system-specific power, which will be one of the future development goals of power companies.

3. In addition to technology, in order to succeed in the power management market, what are the elements?

Power management technology providers have not only limited to the power technology itself, but need to combine the power supply and system knowledge better, and develop better performance and application products for system applications. For example, for wired applications, as optical fiber transmission speed increases, for example, at 30G and 100G, higher requirements are imposed on the bandwidth of the noise, and the bandwidth of the noise suppression required by the LDO increases accordingly. In the application of radio frequency, because of the increase of the transmitting and receiving channels, put forward the new demand in the power of the power, noise, so need the power company to understand the application, develop more suitable products of the application.
