Quais são os principais componentes dos materiais da bateria de lítio? Quatro materiais principais da bateria de lítio são brevemente apresentados

bateria de lítio is a kind of battery composed of lithium metal or lithium alloy as positive / material de eletrodo negativo, usando solução eletrolítica não aquosa. Devido às características químicas do lítio metálico são muito ativos, fazendo o processamento, preservação e uso de lítio metálico, os requisitos ambientais são muito elevados. Com o desenvolvimento da ciência e tecnologia, lithium battery has become the mainstream.

1. Quais são os principais componentes dos materiais da bateria de lítio

Carbon anode materials: the actual anode materials used in lithium ion batteries are basically carbon materials, such as artificial graphite, natural graphite, intermediate phase carbon microspheres, petroleum coke, carbon fiber, pyrolysis resin carbon, etc.

Tin-based cathode materials: Tin-based cathode materials can be divided into tin oxide and tin-based composite oxide. Oxide refers to the oxide of various valent metal tin. There are no commercial products available.

Nitrides: No commercial product.

Alloy category: including tin-based alloy, silicon-based alloy, germanium-based alloy, aluminum-based alloy, antimony-based alloy, magnesium-based alloy and other alloys, and there are no commercial products.

Nanoscale: nano-carbon tubes, nano-alloy materials.

Nanooxide: According to the latest market developments in the lithium battery new energy industry in 2009, many companies have begun to use nano titanium oxide and nano silicon oxide to add to the previously traditional graphite, tin oxide, nano carbon tubes, greatly improving the charge and discharge volume and charge and discharge times of lithium batteries.

2. Four main materials for lithium batteries

Lithium battery material composition mainly includes cathode material, material catódico, diaphragm and electrolyte.

1, cathode materials: among the lithium cathode materials, the most commonly used materials are lithium cobalt oxide, lithium manganese oxide, lithium iron phosphate and ternary materials (polymer of nickel cobalt manganese).

2, cathode materials: among the cathode materials, the current lithium battery cathode materials are mainly natural graphite and artificial graphite. The anode materials being explored are nitrides, NÃO, óxidos à base de estanho, ligas de estanho, nanoanode materials, e alguns outros compostos intermetálicos.

3, diafragma: market diaphragm materials are mainly polyethylene (polyethylene, PE), polypropylene (polypropylene, PP) based polyolefin (Polyolefin) diafragma. In the structure of lithium battery, o diafragma é um dos principais componentes da camada interna.

4. Electrolyte: the electrolyte is composed of high purity organic solvent, sal eletrólito de lítio, aditivos necessários e outras matérias-primas, sob certas condições, de acordo com uma certa proporção.
