摘要：
Thermoresponsive smart electrolytes based on Pluronic solution are developed for active control and thermal self-protection of electrochemical energy-storage devices. Mechanistic studies reveal that the highly effective and reversible self-protection behavior is attributed to the sol-gel transition of the Pluronic solution upon temperature change. The transition temperature and the degree of performance suppression can be tuned over a wide range.
