Energy Storage & Conversion:
Batteries store chemical energy and convert it into electrical energy, powering devices from small gadgets to electric vehicles (EVs) and grid systems.
Rechargeability:
Many batteries (e.g., Li-ion) support multiple charge-discharge cycles, reducing waste and long-term costs compared to single-use alternatives.
Safety & Environmental Impact:
Modern batteries incorporate features like thermal management and non-toxic materials (e.g., LiFePO4) to minimize risks and ecological harm.
Diverse Chemistries:
Common types include lithium-ion, lead-acid (cost-effective but heavy), nickel-metal hydride (NiMH, eco-friendly), and solid-state (safer, longer-lasting).
Portability & Scalability:
Designs range from compact AA batteries for remotes to large-scale EV battery packs, adaptable to varying power demands.
Efficiency & Performance Metrics:
Key attributes include energy density (Wh/kg), power density (W/kg), cycle life, and fast-charging capability, tailored to specific applications.
