 This study proposes a new type of non-Newtonian fluid quasi-solid electrolyte, NNFQSE, which consists of sulfonated silicon nanoparticles, liquid electrolyte, and polymer network. This material has both shear thinning and shear thickening properties, making it ideal for use in LiO2 batteries. It also has the ability to respond to sudden changes in force, such as high current rates, by turning from shear thinning to shear thickening. This allows the material to prevent lithium dendrites from forming and penetrating into the battery, thus increasing its lifespan. When combined with the NNFQSE, the lithium-symmetrical battery can run for more than 2,000 hours at 1 mA Cm2 at room temperature, and the quasi-solid LiO2 battery can last up to 5,000 hours at 100 mA G1.
