Key Characteristics and Types:
High Energy Density: Stores significant power in small, light packages.
Chemistry Variations: Common types include Lithium Cobalt Oxide (consumer electronics) and Lithium Iron Phosphate (LiFePO4) (high safety/long life).
Long Cycle Life: Capable of many recharge cycles, making them cost-effective over time.
Safety Considerations: While efficient, they can face risks like thermal runaway if damaged or overheated, although LiFePO4 offers superior stability.
