The main categories of lithium-ion batteries, do you know?

Posted on 2022-08-23

In recent years, lithium-ion batteries have been widely used in the field of military and industrial equipment, such as AGV mobile cars, energy storage power supply, robots and so on, partly replacing traditional batteries because of their advantages such as high specific energy, high battery voltage, wide operating temperature range and long storage life.

When a lithium-ion battery is charged, the lithium-containing compounds in the positive electrode release lithium ions, which travel through the electrolyte to the negative electrode. When a battery is discharged, the process by which we use it, the lithium ions embedded in the carbon layer of the negative electrode escape and move back to the positive electrode. We usually refer to the battery capacity is the discharge capacity. In the charging and discharging process of lithium ion battery, lithium ion moves from positive electrode to negative electrode to positive electrode.

(I) According to the different electrolyte materials used in lithium ion batteries, lithium batteries can be divided into liquid lithium battery (LIB) and polymer lithium battery (LIP).

(2) According to the charging mode, it can be divided into two categories: non-rechargeable and rechargeable.

(3) Lithium battery appearance: square lithium battery (such as commonly used mobile phone battery) and column (such as 18650, 18500);

(4) Lithium battery outsourcing materials: aluminum shell lithium battery, steel shell lithium battery, soft bag battery;

(V) Lithium battery is divided into positive and negative electrode materials (additives) : lithium cobalt acid (LiCoO2) battery, lithium manganese acid (LiMn2O4) battery, lithium iron phosphate battery, disposable lithium manganese dioxide battery
