The Li-polymer battery is using file alloy as the positive electrode. It uses polymer conductive materials, polyacetylene, polyaniline, or poly-p-phenol for the negative electrode. It uses organic solvent as the electrolyte. The specific energy of the 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 lifetime is about 330 times.
Precautions for using lithium polymer batteries.
- Always store the battery in a fireproof container.
- Always use a proper charger designed for Li-polymer batteries for charging.
- Always follow the manufacturer’s instructions for charging and discharging rates of lithium polymer batteries.
- Always determine if a li-polymer battery can be used according to its intended use.
- Never overcharge (overcharge) a li-polymer battery.
- Never overcharge (over-discharge) a li-polymer battery.
- Do not use expanded Li-polymer batteries (bulging batteries).
- Do not use a li-polymer battery with obvious damage (dents, cracks, etc.).
- Do not charge the Li-polymer battery unattended.
For external.
The following are measures for the use of the battery cells, including the protection of the aluminum composite film, top sealing edge (pole handle end sealing edge), side sealing edge, pole handle and to avoid mechanical impact and short circuits.
- Aluminum-plastic composite film outer packaging protection. Mainly to avoid being damaged by sharp parts piercing. To this end, the battery’s surrounding environment should be cleaned from time to time. Prohibit sharp parts from touching or colliding with the battery cells. You can wear gloves when you take them to avoid fingernails scratching the surface of the battery cell.
- Top sealing edge and side sealing edge protection. To avoid damage to the top sealing edge and side sealing edge and destroy the sealing effect, bending the top sealing edge and side sealing edge should be prohibited. At the same time, the core design must take reliable insulation isolation measures to avoid docking short circuits of the negative pole and aluminum-plastic composite film.
The principle of advantage.
Lithium polymer batteries are the newer generation of batteries, which entered the market in large quantities in 1999. Lithium polymer batteries are the same as li-polymer batteries except that the electrolyte is a solid polymer instead of a liquid electrolyte.
The polymer electrolyte material is a common film consisting of a solute. In the solute, the subject polymer, such as an oxide of polyethylene, acts as an immobile solvent. The advantage of li-polymer batteries is that they can be made in any shape and are relatively light. This is because it does not contain heavy metals and has a plastic shell that keeps the electrolyte from leaking. They all perform better. Ideally, li-polymer batteries have a capacity of several thousand mA⋅h and are safer. The solid electrolyte acts like a hermetic gel and does not easily disintegrate during charging.
