13 Surprising Applications of Lithium-Ion Batteries

Portability and efficiency have driven lithium-ion batteries to revolutionize several industries. You might believe that the RV, boat, and golf cart industries have completely embraced lithium-ion batteries, but these batteries are even more common than you’d think.

Here are 13  uses of lithium-ion batteries.

1. Laptops, cell phones, and tablets

These everyday-use items require portability, a lot of power, and constant recharging, which is why durable and safe lithium-ion batteries are a perfect fit.

2. Smartwatches

Although it’s a much smaller version of the above, you might be surprised to learn that smartwatches use lithium-ion batteries as well. The safety of lithium-ion batteries is beneficial for smartwatches, since they’re worn so close to our skin throughout the day.

3. Electric Toothbrushes

You might not think there are any lithium-ion batteries in your bathroom, but electric toothbrushes commonly use them to help you keep your teeth clean.

4. Calculators

These small lithium-ion batteries exist in the classroom as well, as they are commonly used by calculators (many of which are recharged by solar energy).

5. Electric Thermometers

The electric thermometer in your medical kit most likely uses a lithium battery to consistently take your temperature correctly.

6. Security Systems

If security systems were entirely run with electricity, a simple power outage would render them useless. Most run on a primary or backup lithium-ion battery to ensure consistent function. This is especially common for remote security systems.

7. Carbon Monoxide and Smoke Detectors

Like security systems, carbon monoxide and smoke detectors run on lithium batteries to make sure they’re running at all times. Some run on hardwired electricity and use rechargeable lithium-ion batteries as a backup power source.

8. Electric Cars

Electric vehicles, such as Teslas, run on lithium-ion batteries. You can recharge them at charging stations around the world.

9. Hearing Aids and Pacemakers

Lithium-ion batteries are also used in life-altering and life-saving devices such as hearing aids and pacemakers. Like smartwatches, users can have the peace of mind of knowing that their battery is safe compared to alternatives.

10. DSLR Cameras

The invention of lithium-ion batteries has been integral to the growth of big camera companies. These video cameras use lithium-ion batteries to help them run smoothly.

11. Bluetooth Headphones and Headset

Although they may seem too small, wireless headphones use lithium-ion batteries to help you listen to your music without powering down.

12. Game Controllers

Wireless game controllers use lithium-ion batteries to hold a charge while you beat a final boss or win an esports championship.

13. E-cigarettes

E-cigarettes use lithium-ion batteries to heat the e-liquid that is then inhaled.

While it’s fun to know where a small lithium-ion battery may be hiding, it’s also useful for environmental purposes. Lithium-ion batteries must be recycled at a proper facility, not thrown away, as they contain metals and other toxic or corrosive substances. Try visiting a local electronics store, or recycling center, or check to see if your manufacturer offers a return program.


By being aware of the lithium-ion batteries in your home, you can prevent disposing of hazardous waste that can be harmful to the environment.
