Rechargeable batteries, also known as secondary batteries, are energy storage devices designed for repeated use by being charged, discharged, and recharged. Unlike their disposable counterparts, these batteries can be used multiple times, providing a sustainable and cost-effective power solution. Their main function lies in their ability to efficiently store electrical energy and release it when needed, making them integral in various electronic devices ranging from mobile phones to electric vehicles.
The primary uses of rechargeable batteries include powering consumer electronics, automotive applications, and renewable energy systems. They are favored for their durability, high energy density, and ability to reduce waste compared to single-use batteries. Characteristics such as long life span, fast charging capabilities, and robustness in various temperatures enhance their appeal. Prominent manufacturers of rechargeable batteries include Panasonic, Samsung SDI, and LG Chem, each known for their innovation and reliability in battery technology.
