Abstract:
A solid-state rechargeable 3D microbattery is provided that has improved power density, energy density, and cycle lifetimes. These improvements are afforded by providing a solid-state electrolyte that is composed of crystalline Li1+xAlxTi2−x(PO4)3, wherein x is from 0 to 2. The solid-state electrolyte that is composed of crystalline Li1+xAlxTi2−x(PO4) has a high ionic conductivity (which is greater than 10−4 Siemens/cm) as well as high chemical stability.
