电解质 Electrolyte

商品分类描述:

   锂电池主要由正极材料、负极材料、电解液和隔膜四大部分组成。其中,电解液是锂电池的“血液”,在正负极之间传导离子和电子。合适的电解液必须具备以下性能:离子电导率高,电化学稳定窗口宽,热稳定性能好和安全低毒,以保证锂电池具备高电压、高比能等优点。作为锂电池的关键原材料之一,电解液成本约占锂电池生产成本的5%-13%左右。
   电解液通常由锂盐、高纯度有机溶剂和添加剂在一定条件下、按一定比例配制而成。其中,锂盐占电解液的质量比例在1:7 左右。常见的锂盐包括六氟磷酸锂、六氟砷酸锂、高氯酸锂、四氟硼酸锂、三氟甲磺酸锂等。


Lithium battery is mainly composed of cathode material, anode material, electrolyte and diaphragm. Electrolyte is the "blood" of the lithium battery, conducting ions and electrons between the positive and negative electrodes. Suitable electrolyte must have the following properties: high ionic conductivity, wide electrochemical stability window, good thermal stability and low toxicity, to ensure that lithium battery has the advantages of high voltage, high specific energy. As one of the key raw materials of lithium battery, the cost of electrolyte accounts for about 5-13% of the production cost of lithium battery.

Electrolyte is usually made up of lithium salts, high purity organic solvents and additives with a certain proportion under certain conditions. Among them, the mass ratio of lithium salts in the electrolyte is about 1:7. Usually, lithium salts include lithium hexafluorophosphate, lithium hexafluoroarsenate, lithium perchlorate, lithium tetrafluoroborate and lithium trifluoromethanesulfonate, etc.
