What are the lithium battery classification? Detailed explanation of the mainstream technology of power lithium batteries.best battery for home inverter

　　The power lithium batteries of new energy vehicles can be divided into secondary batteries (including lead -acid batteries, nickel -cadmium batteries, nickel -metal hydride batteries, lithium -ion batteries) and fuel power batteries.

　　Lithium battery manufacturers refine it and start from the classification of lithium batteries to analyze the mainstream technical roads of power lithium batteries on the market.

　　working principle

　　First correct a concept. Lithium batteries are different according to the data used in positive and negative poles, and usually divided into two categories:

　　Lithium metal batteries also use manganese dioxide as the positive electrode data, metal lithium or its alloy metal is a battery of negative data; lithium -ion batteries, lithium alloy metal oxides are used as positive electrode data, and graphite is a negative electrode data battery.

　　The nature of lithium metal batteries is not stable enough and cannot be charged, so it is not a secondary battery. Regarding the new energy sedan, the lithium -ion battery we usually say refers to lithium ion batteries.

　　Lithium batteries are important composed of positive electrode (including lithium compounds), negative electrode (carbon data), electrolyte, and diaphragm:

　　During the battery charging, the lithium ion ion and electron (dehydration) of the lithium atomic electrical ion is ionized. Lithium ions are moved to the negative electrode through electrolyte, which gets electrons, and is restored to lithium atoms into the carbon layer micro -hole (inserted);

　　When the battery is discharged, the lithium atoms embedded in the negative electrode carbon layer, lost electrons (removed) into lithium ions.

　　The charging and discharge process of lithium batteries is also the process of lithium ion that is constantly embedded and dehydrated between positive and negative poles. At the same time, it is accompanied by the embedded and dehydration of equivalent electrons. The more lithium ions, the higher the charging and discharge capacity.

　　Classification

　　Due to the different information of the positive electrodes, lithium -ion batteries are important: lithium iron phosphate (LFP), lithium nickel (LNO), lithium manganate (LMO), lithium cobaltate (LCO), and nickel cobalt acid lithium (NCM ), Nickel cobalt aluminate ternary lithium (NCA), litter carbon data is important.
