Automotive emergency start power in the polymer lithium battery

Li-ion is widely used in communication and electronics industries as a high efficiency energy carrier, especially in personal communication devices such as cell phones and PDAs. However, with the rapid development of communication technology in recent one or two years, the appearance of mobile phone color screen technology, multimedia messaging technology, Bluetooth technology and camera technology continue to appear, and the battery capacity, volume, weight and electrochemical performance and other indicators put forward higher requirements , The traditional liquid lithium has been increasingly unable to adapt to new needs. The new polymer lithium-ion battery (Li-Poly) appeared to meet this demand. Lithium polymer battery is the third generation lithium ion battery developed on the basis of the original steel shell and aluminum shell battery. Due to its lighter, thinner and higher energy density, it is widely used in domestic and foreign communication terminals Manufacturers and design companies of all ages. The most fundamental difference between a polymer lithium-ion battery and a liquid lithium-ion battery is that the electrolytes used in the two are different. Lithium-polymer battery electrolyte from the appearance of solid, known as the polymer solid electrolyte. This electrolyte is a class of polymer materials that are in a solid state but dissolve the supporting electrolyte like a liquid and can undergo ion migration.

Here are a few examples of the eight advantages of using automotive emergency start power lithium polymer for peer reference.

A.K.E 12V / 1300mAh lithium polymer battery engineering model, equipped with automatic protection board, can short-circuit, overcharge, over discharge for effective protection. But also enable the battery to use a normal charger for reliable charging without having to worry about overcharging or underfilling conditions. Polymer lithium battery cell voltage is usually 3.7V, the maximum voltage of 4.2V.mobile power plant

1. Safety performance is good

Polymer lithium battery in the structure of the aluminum-plastic flexible packaging, unlike the liquid metal case of the metal shell, in the event of security risks, liquid batteries explode easily, and at most only the polymer batteries gas drum.

2. Small thickness, can be made thinner

Ordinary liquid lithium battery first custom shell, after the plug positive and negative village material method, the thickness of 3.6mm below the technical bottlenecks exist, the polymer batteries do not exist this problem, the thickness can be less than 1mm, in line with the current demand for mobile phones direction.

3. Light weight

Polymer battery weighs 40% lighter than the same size lithium steel, aluminum battery lighter than 20%.

Large capacity

Polymer batteries than the same size steel shell battery capacity 10 ~ 15% higher than the aluminum battery 5 to 10% higher, a color phone and MMS phones become the first choice, and now the market out of the color screen and MMS phones are mostly used Polymer batteries.

5 small internal resistance

The internal resistance of polymer batteries than the average liquid batteries is small, the current domestic resistance of polymer batteries can even do below 35mΩ, which greatly reduces the battery's self-consumption of electricity to extend the standby time of the phone can be achieved With the international standards. This polymer lithium-ion battery, which supports large discharge currents, is ideal for remote control models and is the most promising alternative to NiMH batteries.

6. Shape can be customized

Polymer batteries according to customer demand increase or decrease the thickness of the batteries, the development of new cell models, cheap, open mold cycle is short, and some can even be tailored to the phone shape to take full advantage of the battery shell space to enhance the battery capacity.

Good discharge characteristics

Polymer batteries using colloidal electrolytes, compared to liquid electrolyte, colloidal electrolytes with stable discharge characteristics and higher discharge platform.

8. Protection board design is simple

Due to the use of polymer materials, batteries do not fire, do not explode, the battery itself has enough security, so the polymer battery protection circuit design may consider the omission of PTC and fuses, thus saving battery costs.

Automotive emergency start-up power Lithium-polymer batteries offer significant advantages in terms of safety, volume, weight, capacity, and discharge performance, but prices have become a problem with polymer due to the current low production costs and high manufacturing costs, Lithium battery popularity bottleneck. According to industry analysts, to 200? Year, lithium polymer battery will occupy the world mobile phone battery market about 1/4, representing the future direction of mobile phone battery.
