¿Cuáles son los componentes principales de los materiales de la batería de litio?? Se presentan brevemente cuatro materiales principales de la batería de litio.

Batería de Litio is a kind of battery composed of lithium metal or lithium alloy as positive / material de electrodo negativo, utilizando una solución electrolítica no acuosa. Debido a las características químicas del metal de litio son muy activos, haciendo el procesamiento, conservación y uso del litio metálico, los requisitos ambientales son muy altos. Con el desarrollo de la ciencia y la tecnología, lithium battery has become the mainstream.

1. ¿Cuáles son los componentes principales de los materiales de la batería de litio?

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 de cátodo, 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, NO, óxidos a base de estaño, aleaciones de estaño, nanoanode materials, y algunos otros compuestos intermetálicos.

3, diafragma: market diaphragm materials are mainly polyethylene (polyethylene, PE), polypropylene (polypropylene, PP) based polyolefin (Polyolefin) diafragma. In the structure of lithium battery, el diafragma es uno de los componentes clave de la capa interna.

4. Electrólito: the electrolyte is composed of high purity organic solvent, sal de litio electrolito, aditivos necesarios y otras materias primas, bajo ciertas condiciones, según una cierta proporción.
