A battery is a device that stores energy in chemical reactions. It’s kind of like an electromagnet, except it uses chemical reactions instead of electricity. The two main types of batteries are primary (non-rechargeable) and secondary (rechargeable).
Batteries are the power sources for electronic devices. The battery is a device that converts chemical energy into electrical energy, which can then be used to power electrical devices such as flashlights, calculators and computers.
In the past, batteries were made from materials such as silver oxide, zinc carbon and nickel-cadmium. However, those materials can only store a limited amount of energy before needing to be recharged again.
Today’s batteries are made of lithium ion cells. These types of batteries have significantly increased in capacity and longevity over the years because they use less material than previous types of batteries while still performing well when compared to other types of batteries on the market today.
Lithium ion battery is the most common type of battery used in portable electronic devices. Lithium ion batteries have a high energy density, which makes them efficient and powerful.
