The Basics of Energy Storage

At their core, batteries store chemical energy in molecular bonds. For lithium-ion solar batteries:

• Charging: Electrons push lithium ions from cathode to anode, storing energy chemically.
• Discharging: Lithium ions move back to the cathode, releasing electrons to power lights, fridges, and other home appliances.

Rechargeable lithium-ion batteries are compact, efficient, and ideal for home solar energy storage.
