Pulse High Temperature Sintering to Prepare Single‐Crystal High Nickel Oxide Cathodes with Enhanced Electrochemical Performance

For the currently most dominant cathode of Li(NixCoyMnz)O2(NCM, x + y + z = 1) in lithium‐ion batteries, higher nickel content brings higher energy density but is accompanied by heavier interfacial reactions with electrolyte and worse safety performance. Single crystal cathode materials have the adv...
