Batteries are versatile devices used to store chemical energy and convert it into portable electrical energy, powering a vast array of devices and systems. Their applications span numerous sectors, from everyday household items to large-scale energy storage solutions.
Household Applications
- Backup Power: Batteries provide crucial backup power during power outages. They're connected to appliances to maintain functionality when the main power supply fails. This is particularly relevant in situations where fluctuating energy costs influence usage patterns. (Reference: Batteries mainly provide backup power during a power outage.)
- Everyday Electronics: Many household devices, such as radios, infrared goggles, and various other tools, rely on batteries for operation. (Reference: Batteries are used in radios which are used to communicate. Even infrared goggles and different field devices are powered by batteries.)
Transportation
- Electric Vehicles (EVs): Lithium-ion batteries are the dominant technology in electric cars, storing energy for propulsion. (Reference: Lithium-ion batteries are currently used in most portable consumer electronics such as cell phones and laptops because of their high energy per unit mass and…) During driving, the batteries discharge to power the motor; during charging, they recharge, undergoing chemical changes to store electricity. (Reference: When the car's recharging, electricity is used to make chemical changes inside its batteries. When it's being driven, the batteries are used to…)
Consumer Electronics
- Portable Devices: Most portable electronics, including cell phones and laptops, use batteries for power. Their high energy density makes them ideal for this application. (Reference: Lithium-ion batteries are currently used in most portable consumer electronics such as cell phones and laptops because of their high energy per unit mass and…)
Large-Scale Energy Storage
- Grid-Scale Storage: Large-scale battery systems are increasingly used in power grids to store renewable energy (like solar and wind) and improve grid stability. (Reference: Lithium-ion batteries, which are used in mobile phones and electric cars, are currently the dominant storage technology for large scale…) This helps manage energy fluctuations and enhance the reliability of renewable energy sources.
Other Applications
The applications of batteries continue to expand as technology develops. Scientific advancements are constantly improving battery technology leading to new industrial and commercial applications. (Reference: As scientists supported by the BES program achieve new advances in battery science, these advances are used by applied researchers and industry to advance…)
Proper Disposal: Used batteries, especially those containing hazardous materials, require careful disposal to protect the environment. Recycling programs and household hazardous waste collection sites are available. (Reference: This page can inform you on how to manage these batteries safely. Waste batteries can always be recycled or taken to household hazardous waste collection…) Many batteries are regulated as hazardous waste when not from households. (Reference: Many batteries, including lead-acid batteries, are regulated as universal (hazardous) waste when not generated by households.)
