Non-flammable solvent-free liquid polymer electrolyte for lithium metal batteries

Nature Communications, Год журнала: 2023, Номер 14(1)

Опубликована: Авг. 1, 2023

As a replacement for highly flammable and volatile organic liquid electrolyte, solid polymer electrolyte shows attractive practical prospect in high-energy lithium metal batteries. However, unsatisfied interface performance ionic conductivities are two critical challenges. A common strategy involves introducing solvents or plasticizers, but this violates the original intention of security design. Here, an concept called without any small molecular is proposed safe high-performance batteries, based on design room-temperature liquid-state brush-like as sole solvent salts. This non-flammable exhibits high conductivity (1.09 [Formula: see text] 10
