High-voltage, solid-state lithium-ion batteries power electric and hybrid vehicles, wearable devices and other high-end technologies. The batteries are made with traditional materials called solid polymer electrolytes, or SPEs, which often explode when damaged.
Purdue researchers have developed a new composite material that is safer than SPEs. The advanced solid electrolyte exhibits stability when cells are damaged – whether folded, punched or cut – which leads to an increase in safety.

“The Purdue researchers’ quasi-solid state battery technology leverages the interfacial stability and ionic conductivity of liquid electrolytes and the energy density and thermal stability of solid electrolytes. This provides a lithium-ion battery with a broad temperature operating range and high ionic conductivity.”
