What will be the future of lithium-ion battery electrolytes?

The National requirement for batteries is 300 watt/kg by 2020. Therefore, increasing the energy density of batteries is the development trend of batteries in the future, and the future development trend of electrolytes is also to cooperate with batteries to improve energy density, safety, and consistency. The following with the power management small compilation to understand the relevant content.

The development of electrolyte application technology attaches equal importance to the improvement of the energy density of supporting batteries and the improvement of the performance of existing systems. Therefore, according to the development trend of batteries in the future, a series of problems that need to be solved are listed, such as how to cooperate with high voltage and high-energy density electrolytes. Different enterprises have different solutions. The current solution is the application of additives and the addition of some new solvents.

The Future Trend of Lithium-ion Battery Electrolytes

At present, many new lithium salts have been studied. As far as the existing lithium salts are concerned, they are considered to be relatively reliable, but the conductivity is very high and there is still some corrosion to the battery. In the past, the electrolyte was more to meet the needs of the 3C market. With the development of power batteries, the former electrolyte plant and battery plant were not well integrated, and the packaging and transportation could not meet the needs of existing batteries. For example, there are contradictions in the fact that battery power density is relatively high, energy density is relatively high, and the requirement for consistency is very high, which is far from the basic requirement of 3C batteries. The first is that the electrolyte production enterprises need some highly automated and intelligent equipment to ensure the consistency of the electrolyte. The second is to meet the needs of the battery during the transportation process. In fact, sometimes the electrolyte is greatly affected by the temperature. As an existing solvent, the temperature, solution point, and negative point are affected by the temperature, so transportation to the manufacturer may have caused uneven or poor consistency.

After all, the 3C market is a small batch and a lot of lots. With the development of the new energy car market, the demand for power batteries is very large. We need to stand higher. We need to meet the needs of new energy vehicles and look at electrolytes from the perspective of automobiles. There will be a new understanding of the electrolyte. Therefore, it is recommended that the industry carry out integration, the existing electrolyte factory and battery factory must be integrated together, in order to meet the demand of new energy vehicles for batteries.
