High voltage solar batteries are designed to operate at elevated pressures, which allows for increased energy density and improved safety features. The core components of these batteries include the anode, cathode, electrolyte, and separator. The anode is typically made from graphite, while the cathode may consist of lithium cobalt oxide (LiCoO₂), lithium iron phosphate (LiFePO₄), or other novel materials. The electrolyte, usually a lithium salt dissolved in a solvent, facilitates the movement of lithium ions between the anode and cathode during charging and discharging.
