An electrolyte with lithium dendrites suppression for high temperature operability

The state-of-art Li-ion batteries have revolutionized the portable electronic industry and first-generation electric vehicles due to their high energy density at ambient temperatures. Owing catastrophic failures under heat, these power devices are incompatible for applications such as in defence arsenals, subsurface drilling, space exploration medical appliances, where performance high-temperatures critical. Herein, we report an electrolyte formulation consists of Lithium bis(oxalato)borate (LiBOB) salt dissolved propylene carbonate that enables lithium operate extended temperature regime (>100 °C). fundamental characterization system ionic conductivity, internal resistance with respect promising desired applications. Further, is used fabricate observed electrochemical results dendrites suppression capability confirmed its suitability without compromising performance.
