Accelerated Ageing! Radiolysis is used as a tool to study the ageing phenomena occurring in various diethyl carbonate/LiPF6 solutions. The degradation products obtained by radiolysis are similar to the ones occurring in electrolysis of Li-ion batteries (LIBs) (see scheme). The research validates the use of steady-state and pulse radiolysis as tools to quickly investigate the reactivity of newly developed electrolytes.
