26650 lithium battery cathode material

release time:2022-12-05 Hits:     Popular:AG11 battery

  18500 1000MAH 3.7V

  26650 lithium battery cathode materials include lithium cobalate, lithium manganate, nickel cobalt aluminum ternary, nickel cobalt manganese ternary, lithium iron phosphate, etc. The material system determines the operating voltage and unit capacity of the battery. All material manufacturers and cell manufacturers improve the voltage and capacity of the overall battery by adding special materials, coating process, manufacturing process improvement, etc, Generally, the working voltage and theoretical gram capacity of various materials are:

  Lithium cobalate 3.6V theoretical capacity is 274mAh/g

  Lithium manganate 3.7V theoretical capacity 148mAh/g

  The theoretical capacity of 3.65V ternary material is 278mAh/g

  Lithium iron phosphate 3.2V theoretical capacity is 170mAh/g

  Various materials themselves will determine the cycle life of the battery, and the manufacturing level of the battery manufacturer will also affect the life.

  Advantages of 26650 lithium iron phosphate battery

  High energy density: theoretical specific capacity is 170mAh/g, actual specific capacity ≥ 140 mAh/g (0.2C, 25 ° C);

  High safety: the safest cathode material for lithium ion batteries at present;

  No pollution: no heavy metal elements harmful to human body;

  Long cycle life: it can be charged and discharged more than 2000 times under 100% DOD;

  Fast charging performance: lithium battery made of lithium iron phosphate cathode material can be charged at a large rate.
