Lithium Battery Electrolyte Solvent
Sep 10, 2018

The lithium battery electrolyte Solvent is the carrier for ion transport in the battery. It is generally composed of a lithium salt and an organic solvent. The electrolyte acts as a conducting ion between the positive and negative electrodes of the lithium battery, and is a guarantee for the high voltage and high specific energy of the lithium ion battery. Electrolyte is usually made up of high purity organic solvents, electrolyte lithium salts, necessary additives and other raw materials, under certain conditions, in a certain proportion.

The lithium battery electrolyte Solvent includes Ethyl Methyl Carbonate (EMC), Diethly Carbonate (DEC) and Dimethyl Carbonate (DMC). They can not only be widely used as solvents for electrolytes of lithium-ion batteries, but also as solvents for special perfumes and intermediates.

As more and more electric vehicles enter the market, people begin to focus on the performance and life of lithium batteries. In the past few years, under the impetus of the national new energy industry policy, a frenzy of manufacturing lithium batteries has been set up across the country. Lithium battery cells and assembly companies have increased to more than 400 (including lithium batteries for new energy vehicles), and lithium-ion battery companies involved in electric vehicles once existed 200-300. Electric vehicle batteries are divided into two categories: batteries and fuel cells. Batteries are suitable for pure electric vehicles, including lithium batteries, lead-acid batteries, nickel-hydrogen batteries, sodium sulfur batteries, air batteries. In the past three or four years, after the efforts of domestic lithium battery materials companies, the core technology for manufacturing lithium batteries has made a major breakthrough. For lithium batteries for electric vehicles, all core materials have basically achieved localization rate. At present, the lithium battery includes the 48v11Ah (using 18650 cylindrical steel shell, each battery is 2200mA, 65 batteries in series and parallel) in groups, the price is less than 500 yuan, compared with lead-acid batteries, Cost-effective advantage. This price is already about one-third of the lithium battery just introduced to the market. It can be seen that lithium batteries gradually replace lead-acid batteries.
