Why high rate lithium battery?
High rate battery generally refers to lithium battery. Lithium battery is a rechargeable high rate battery, which mainly depends on the movement of lithium ions between the positive electrode and the negative electrode. During charging and discharging, Li + is intercalated and de intercalated back and forth between the two electrodes: when charging the battery, Li + is de intercalated from the positive electrode and embedded into the negative electrode through the electrolyte, and the negative electrode is in a lithium rich state; The reverse is true when discharging. Batteries that generally use materials containing lithium elements as electrodes are representative of modern high-performance batteries.
Rapid charging of ordinary rate battery is easy to cause lithium separation from the negative electrode, resulting in accelerated performance degradation of the lithium battery. In serious cases, it may cause internal short circuit of the battery and cause fire and explosion. Most consumer applications only need 1C batteries. If higher discharge rate and faster charging time are required, high rate batteries are the best choice.

Advantages of high rate lithium battery
① It has the characteristics of excellent high current discharge performance, sufficient explosive force, high discharge platform and good cycle life;
② It has high energy density and adopts lamination technology. Because of its small internal resistance, it is more conducive to rate charge and discharge and high-efficiency output performance;
③ Provide higher discharge rate, up to 45C, better temperature stability during discharge, controlled within 65 ℃, to prevent overheating and damage;
④ The lithium battery is ultra-thin, small in size and extremely light in weight. It can be made into various shapes and capacities of special-shaped batteries with a thickness of 0.45mm.
