Lithium battery concept and classification

Lithium batteries are a type of batteries that use lithium metal, lithium alloys or lithium ion compounds as negative electrode materials. They are divided into lithium metal batteries and lithium batteries according to different negative electrode materials. Among them, lithium metal battery refers to a type of battery that uses manganese dioxide as the positive electrode material and metal lithium or its alloy metal as the negative electrode material. It is limited to non-rechargeable and is therefore classified as a primary battery; lithium battery refers to a lithium ion embedded battery A type of battery in which the compound is the positive electrode material and the carbon material is the negative electrode. This type of battery has charging performance and is therefore classified as a secondary battery. It not only has high energy density, high output voltage, low self-discharge, no memory effect, and cycle Superior performance, fast charging and discharging, high charging efficiency, high output power, long service life and low environmental pollution. Therefore, it is usually called a green battery. According to the phase state of the lithium battery electrolyte, it can be divided into liquid Two-phase lithium battery and solid-state lithium battery. According to different downstream industries, lithium batteries can be divided into three types: power lithium batteries, 3C lithium batteries, and energy storage lithium batteries. Different battery types have different battery internal resistance, current and capacitance. Among them, 3C lithium batteries are mainly used in consumer products such as mobile phone batteries, laptop batteries, and mobile power supplies; power lithium batteries are divided into multiplying and power types. Multiplying power lithium batteries refer to power tools, starting batteries, and aeromodelling batteries. A battery with a use time of a few seconds to a few minutes. Power-type power ion batteries can be used in pure electric vehicles (EV), electric bicycles (E-bike), electric three-wheeled, electric motorcycles, etc.; energy storage lithium batteries in the future It will be used in energy storage power stations to store electrical energy in lithium batteries during peak power periods and output electrical energy during low power periods. Driven by policies such as energy conservation and environmental protection, power lithium batteries related to new energy vehicles have become a fast-growing segment of the power lithium battery industry.
