Temperature‐Inert Interface Enables Safe and Practical Energy‐Dense LiNi0.91Co0.07Mn0.02O2 Pouch Cells

Safety concerns significantly hinder the practical implementation of ultrahigh‐nickel cathodes in lithium‐ion batteries. The solid electrolyte interphase (SEI) derived from conventional ester‐based electrolyte is susceptible to thermal decomposition, resulting in battery safety degradation. Herein,...
