Characteristics and classification of power batteries.

Characteristics of lithium-ion power batteries
• High capacity
• Low internal resistance

• Extremely thin sheet

Good high rate charging and discharging performance

• Good pulse performance

Higher safety performance requirements
Classification of lithium-ion batteries
• Classified by shell and electrolyte:
(1) Liquid aluminum shell lithium-ion battery
(2) Liquid steel shell lithium-ion battery
(3) Liquid flexible packaging lithium-ion battery
(4) Colloidal polymer lithium-ion battery
(5) Solid state polymer lithium-ion battery
• Classified by shape:
Square, cylindrical, button shaped, card shaped, irregular shaped
Naming of lithium-ion batteries
Square:
W: Cell width
H: Cell height
T: Cell thickness
