Briefly describe the characteristics of polymer lithium batteries and the correct charging method

The lithium polymer battery uses a ruthenium alloy as a positive electrode and uses a polymer conductive material, polyacetylene, polyaniline or polyparaphenylene as a negative electrode, and an organic solvent as an electrolyte. The specific energy of lithium polyaniline battery can reach 350W.h/kg, but the specific power is only 50-60W/kg, the use temperature is -40-70 degrees, and the service life is about 330 times, the following small series for everyone to introduce the lithium polymer battery charging methods and features, let's look at it.

Lithium polymer battery charging method

When we have no power in the phone, we need to charge the battery, so first find a charger that is best used by the original mobile phone. Otherwise, it is easy to cause damage to the battery during charging due to incompatibility or other reasons. . At the same time, everyone knows that mobile phones support fast charging function, but Xiaobian needs to remind everyone here that if we don't have anything particularly important, then we should use slow charging when charging, so as to ensure maximum guarantee, the life of the mobile phone battery.

At the same time, if our mobile phone is not used for a long time, we must first fully charge the polymer lithium battery, and when we fully charge the battery, do not put the battery on the charger, if we are long If the polymer lithium battery is not used at any time, it may cause separation between the battery and the mobile phone, thereby affecting the performance of the mobile phone.

Lithium polymer battery features

Compared to lithium-ion batteries, lithium polymer batteries have the following characteristics:

1. Relatively, the problem of battery leakage is improved, but it has not been completely improved.

2. Can be made into a thin battery: with a capacity of 3.6V250mAh, its thickness can be as thin as 0.5mm.

3. The battery can be designed in a variety of shapes.

4. A single high-voltage: liquid electrolyte battery can only be connected in series with several batteries to obtain a high voltage, and the polymer battery can be made into a multi-layer combination in a single piece to achieve a high voltage because it has no liquid itself.

5. The amount of discharge is theoretically 10% higher than that of a lithium-ion battery of the same size.

Will lithium polymer batteries explode?

Polymer lithium batteries, in the event of a safety hazard, will not explode and will only bulge. In terms of safety, the outer packaging is aluminum-plastic packaging, which is different from the metal casing of the liquid lithium battery. The internal quality hazard can be immediately displayed through the deformation of the outer packaging. Once a safety hazard occurs, it will not explode and only bulge.

At present, most domestic polymer batteries are only soft-packed batteries, which use aluminum plastic film as the outer casing, but the electrolyte has not changed. The battery can also be thinned, its low-temperature discharge characteristics are better than that of polymer batteries, and the material energy density is basically the same as that of liquid lithium batteries and ordinary polymer batteries, but because of the use of aluminum plastic film, it is more than ordinary liquid lithium battery light. In terms of safety, when the liquid is just boiling, the aluminum plastic film of the soft pack battery will naturally bulge or rupture, and will not explode.
