基于专利情报分析的锂离子电池用低温电解液的发展现状和研究进展
Patent intelligence analysis of the research progress in low-temperature electrolytes for Li-ion batteries
摘要
Abstract
Lithium-ion batteries have found widespread use in mobile devices,electric vehicles,and energy storage systems.With the rapid development of informational support systems and modern construction in the military,it is crucial to develop lithium-ion batteries capable of stable operation under low-temperature conditions.This would allow to meet the demands for energy storage and release in high cold areas,bipolar areas,and areas such as high and near space.Electrolytes are key components of Li-ion batteries because of their role in lithium ions transport and in the generation of a solid electrolyte film at the anode and cathode interface.The performance of electrolytes directly affects the low-temperature performance of lithium-ion batteries.Since the optimization of the electrolyte is easy to achieve in practical applications,there has been intensive research related to electrolytes in lithium-ion batteries.This work presents the research progress and issues related to low-temperature electrolytes for lithium-ion batteries.Then an analysis of the patents'applications related to low-temperature electrolytes in lithium-ion batteries was made.The overall applications'profile and the research progress,which is closely related to the market and industry,was evaluated,including technical branches such as electrolyte salts,solvents,and additives.From the patents'analysis,the main applicants were also noted.Finally,the limitations of the domestic innovative bodies are discussed in terms of patent layout.A reference for research in the field of low-temperature electrolytes for lithium-ion batteries is necessary.关键词
