1. The raw materials are different. The raw materials of lithium-ion batteries are electrolytes; The raw materials of lithium polymer batteries are electrolytes, including polymer electrolytes and organic electrolytes.
2. Different in terms of safety, lithium-ion batteries are prone to explosion in high temperature and high pressure environments; Lithium polymer batteries use aluminum-plastic film as the outer casing. is used indoors, even if the liquid is very hot, it will not explode.
3. Different forms. Polymer batteries can be thinned, sized and shaped arbitrarily. The reason is that the electrolyte can be solid or colloidal rather than liquid, while lithium batteries use a sturdy casing. required as secondary packaging to contain the electrolyte.
4. Cell voltages are differentes. Since polymer batteries use polymer materials, they can be made into multi-layer combinations in cells to achieve high voltages. The rated cell capacity of lithium batteries is 3.6V. To achieve high voltage in real-world applications, multiple cells must be connected in series to form an ideal high-voltage working platform.
5. The manufacturing process is different. The thinner the polymer battery, the better it is produced, and the thicker the lithium battery, the better it is produced. This allows lithium batteries to expand their areas of application.
6. Ability. The capacity of polymer batteries has not been improved effectively and has been reduced compared to standard capacity lithium batteries.
Detailed information:
In the battery, lithium ions are dischargedof the negative electrode. during the discharge process. Moves to the positive pole and returns during charging. Compared to metallic lithium used in non-rechargeable lithium batteries, lithium-ion batteries use intercalated lithium compounds as electrode materials. The battery has high energy density, no memory effect and low self-discharge.
However, they can pose a safety hazard because they contain flammable electrolytes that can cause explosions and fires if damaged or improperly charged. Samsung was forced to recall its Galaxy Note 7 phones after lithium-ion batteries caught fire and several battery accidents occurred on Boeing 787s. Chemical, performance, cost and safety characteristics vary depending on the type of LIB.
Portable electronic devices primarily use oxide-based LIBse of lithium and cobalt, which can provide high energy density but pose safety risks, particularly when damaged. Lithium iron phosphate, lithium ion manganese oxide, and lithium nickel manganese cobalt oxide (LiNiMnCoO2? or NMC) batteries offer lower energy density, but longer life and less risk of fire or explosion.
