Abstract
The University of Central Florida invention describes the cell structure of an all-solid-state lithium secondary battery. The proposed design enables uniform lithium deposition to prevent the formation of dendrites. In addition, the design allows a controlled growth of lithium towards a specific direction into a designated area in the cell. The use of lithium metal anodes causes nucleation/growth of dendrites at the surface during multiple battery cycles and/or high-rate charge/discharge. These dendrites lead to micro-shorts between the cathode and the anode causing the degradation of the battery. With these distinct features of the proposed cell structure, the battery will have a prolonged lifetime with stable charge/discharge performance and controlled volumetric change of the battery cell.
Benefit
