battery-cell usually divided into (a) Cylindrical-type, (b) prismatic-type, and (c) pouch-type cells.

(Schematics of inner structures of commercial LIBs.)

(1), according to the different electrolyte materials used in lithium ion batteries, lithium ion batteries can be divided into two categories: liquid lithium ion batteries (lithiumionbattery, referred to as LIB) and polymer lithium ion batteries (polymerlithiumionbattery, referred to as LIP).

(B), according to the charging method can be divided into: non-rechargeable and rechargeable two categories.

(c), lithium-ion battery appearance: there are square lithium (such as commonly used mobile phone batteries) and columnar (such as 18650, 18500);

(d), lithium-ion battery packaging materials: aluminum-cased lithium-ion batteries, steel-cased lithium-ion batteries, soft pack batteries;

(e), lithium-ion batteries from the positive and negative materials (additives): lithium cobaltate (LiCoO2) batteries, lithium manganate (LiMn2O4), lithium iron phosphate ion batteries, disposable manganese dioxide lithium-ion batteries

We often talk about ternary lithium batteries or lithium iron batteries, which are named for lithium batteries according to the active material of the positive electrode. The specific parameters are not identical for cells of the same technological route. The six types of lithium batteries specifically include: lithium cobaltate (LiCoO2), lithium manganate (LiMn2O4), lithium nickel cobalt manganate (LiNiMnCoO2 or NMC), lithium nickel cobalt aluminiumate (LiNiCoAlO2 or NCA), lithium iron phosphate (LiFePO4), lithium titanate (Li4Ti5O12) .
