Rechargeable batteries
Rechargeable batteries are energy storage devices that can be reused multiple times. Unlike disposable batteries, which are used once and discarded, rechargeable batteries can be charged and discharged hundreds or even thousands of times. They work by storing electrical energy through chemical reactions. Common types include lithium-ion and nickel-metal hydride, commonly found in smartphones, laptops, and electric vehicles. The ability to recharge them makes them more environmentally friendly and cost-effective in the long run, reducing waste and the need for frequent replacements.
