The Latest Research Progress in Electrolyte Additives for Lithium Batteries
In view of global warming,rising horizons and other environmental problems,in order to promote the deployment of China's"carbon peak,carbon neutrality"strategic decision-making,the development of high-capacity,low-cost,low-pollution green renewable energy storage devices has become an urgent task,lithium battery as a new type of clean energy storage and conversion device has the advantages of high theoretical specific capacity,environmental friendliness,etc.,is widely used in today's society energy storage and conversion devices,but also in the field of energy storage in the field of key research objects,its performance and reliability are crucial.Electrolyte additives play the role of ion transfer and electron transfer in the process of charging and discharging,and have an important impact on the electrochemical performance,safety performance and cost of batteries.At present,electrolyte additives account for about 5％of the mass of all electrolytes,which has the characteristics of small dosage and significant improvement effect.The research on the ratio of electrolyte additives and the research and development and application of new additives have become one of the core technologies that determine the market competitiveness of additive manufacturers.In this paper,the research progress of lithium battery electrolyte additives is reviewed,mainly from the aspects of the role,classification and latest research progress of additives,and the development trends and challenges of future research are pointed out.
