Lithium batteries have a lithium anode.

Industrial batteries translate chemical energy into electricity.

Battery chargers are devices for charging rechargeable batteries.

Rechargeable batteries or secondary batteries contain active materials that can be regenerated by charging.

Battery packs are constructed from two or more individual cells or batteries.

Semiconductors (metalloids) or semiconductor materials are used to fabricate microelectronic and optoelectronic devices such as transistors, photodetectors or solar cells.

Electrical contacts and contact materials are soft, high-conductivity, oxidation- resistant materials that are used in circuit breakers, relays, switches, and electrical discharge machining (EDM) applications.
