Classification of lithium battery separators.lithium 3400mah 3.7v 18650 battery

release time:2023-08-08 Hits:     Popular:AG11 battery

  

  1、 Equipped with electronic insulation, ensuring mechanical isolation of positive and negative electrodes.

  2、 It has a certain pore size and porosity, ensuring low resistance and high ion conductivity, and has good permeability to lithium ions.

  3、 Due to the strong polarity of organic compounds in the electrolyte, the separator must be resistant to electrolyte corrosion and have sufficient chemical and electrochemical stability.

  4、 Good wettability of electrolyte and sufficient absorption and moisturizing ability.

  5、 Having sufficient mechanical properties, including puncture strength, tensile strength, etc., but with a minimum thickness.

  6、 Good spatial stability and smoothness.

  7、 Good thermal stability and automatic shutdown protection performance. Power batteries have higher requirements for separators, usually using composite membranes.
