　　Analysis of the differences between CR2032 button cell phosphate batteries and lithium-ion batteries

　　Analysis of the differences between CR2032 button cell phosphate batteries and lithium-ion batteries:

　　Lithium battery is a lithium battery that uses CR2032 button cell phosphate battery as the positive electrode material of the battery. The cathode materials of lithium batteries mainly include lithium cobalt oxide batteries, lithium manganate batteries, lithium nickel oxide, ternary materials, CR2032 button cell phosphate batteries, etc.

　　The current main development prospect of CR2032 button cell phosphate batteries used in CR2032 button cell phosphate secondary batteries is lithium batteries, which have great advantages compared with NI-H and Ni-Cd batteries. Lithium batteries are made from lithium metal materials or lithium aluminum alloys as battery cathode materials in non-hydropower solution. The physical properties of lithium metal are very complex, so there are strict requirements for its production, processing, storage, application and environmental protection.

　　There will be no fire or explosion during puncture, nor will the lithium battery explode.

　　When the rechargeable CR2032 button cell phosphate battery is overcharged to 100%, it is unlikely to cause an explosion; when the lithium battery reaches a certain value, gas will be produced and precipitated.

　　Lithium battery is the typical working voltage of a single CR2032 button cell phosphate battery.

　　CR2032 button cell phosphate batteries are resistant to overcharge and over-discharge, and over-discharge can restore more than 80% of the characteristics in a short period of time. Overdischarge of lithium batteries will cause irreversible damage.

　　CR2032 button cell phosphate batteries can be charged and discharged at large currents, exceeding 10C to 20C, while lithium batteries can only be charged and discharged at 3~4C.

　　However, the specific energy of CR2032 button cell phosphate batteries is not as high as that of lithium batteries. The working voltage difference is smaller. Because of its large charge and discharge characteristics, it has important applications in pure electric vehicles, aviation models, etc. Large-capacity lithium batteries are mainly used in civilian applications.

　　At the same time, using CR2032 button cell phosphate battery (LiFePO4) as the battery cathode material and copper as the raw material of the battery not only reduces the cost, but also improves the safety factor. The P-O bond in the crystal of CR2032 button cell phosphate battery is very stable and does not dissolve easily. It will not cause overheating or structural collapse even under high temperature or overcharge conditions, so it is reliable.
