As lithium-ion batteries(LIBs)gain wide spread use in electric vehicles and energy storage systems,preventing the degradation of their electrochemical performance has emerged as a key research focus.The research shows that the high quality interfaces between electrode and electrolyte are important means to reduce side reactions,improve electrochemical reversibility and cycle performance.In this paper,the global patents in the field of LIB"electrode/electrolyte"interface technologies are investigate.By using patent data mining method,the global patent application trend and growth rate,geographical distribution &flow,applicants,different technology branches are analyzed.Finally,suggestions are put forward to pay attention to underdeveloped technology areas,promote international collaboration,and strengthen overseas patent protection.
