Although it rarely happens, lithium ion batteries can, under certain conditions, ignite, damaging devices and risking life. Now, Katie Zhong and colleagues at Washington State University have developed a gummy, sol-gel, electrolyte that precludes leakage. The gummy electrolytes show excellent performance in adhesion/contact, structural integrity under various deformations, high ionic conductivity, and safety (thermal-protection and leakage-free properties). These results indicate that the gummy electrolyte is a viable solution for safe and flexible/stretchable lithium ion batteries, the team reports in the journal Advanced Energy Materials.
