18650 lithium-ion battery

　　18650 lithium-ion battery phosphate batteries can be divided into soft packs and cylindrical ones. The cylindrical shapes include 18500, 18650, 14500, 26650, etc. According to incomplete statistical analysis, there are still hundreds of lithium-ion battery manufacturers in my country. With the continuous development of the lithium-ion battery manufacturing industry, these data have been continuously improved.

　　What are the advantages of cylindrical 18650 lithium-ion battery phosphate batteries?

　　*Effective relative density of energy

　　The energy is three times that of lead-acid batteries and twice that of nickel batteries.

　　*Wide operating temperature categories

　　The charging and discharging temperature range is 0~60℃, and the charging and discharging temperature range is -20~60℃.

　　*Good working ability to actively store charge

　　Due to the advantages of lithium-ion battery's low life, lithium phosphate rechargeable battery can still have high power consumption for long-term storage.

　　*High rate discharge characteristics

　　Continuous 10c current charge and discharge, instantaneous single pulse charge and discharge rate is greater than 20c.

　　*No memory

　　Lithium phosphate batteries do not need to be charged or discharged before charging.

　　*Reliable safety factor

　　The raw material structure of lithium phosphate battery is stable and the safety factor is reliable. When extreme conditions such as collision, pressure, pinning, short-circuit failure, over-battery charging, overheating, etc. occur, explosion accidents or ignition are unlikely to occur.

　　*Long life cycle

　　The chemical structure of the rechargeable battery is almost unchanged when the battery is recharged, showing a 1000 times battery charging cycle system, showing higher user value. The Lifepo4 battery pack recycling system has a long service life of up to 2000 cycles.

　　*Environmental protection

　　Lithium phosphate rechargeable batteries do not contain harmful elements such as mercury, cadmium, and lead. They are known as a new generation of green switching power supplies and meet high market environmental protection requirements.

　　*low cost

　　Iron and polyphosphate are both common components of the earth. The comprehensive application cost is lower than lead-acid batteries and lithium manganate batteries.
