Turn your old laptop battery into an electric charger

If your laptop is damaged, keep the battery. Laptop batteries can help you power your home appliances and help keep the environment green.

Researchers at IBM have unveiled UrJar , a device that turns old lithium-ion batteries into rechargeable power for low-power devices such as LEDs, fans, and cell phones. motion. To create this device, the team removed lithium-ion cells that could operate from the battery and incorporated them with the circuit board and charging connector.

According to IBM, a 85Wh battery after three years of use is only 50Wh. Still, it can still light a 3W LED, a 6W fan or a 3.5W cell phone charger for use for about 4 hours a day. This is an extremely positive result. This research will also help to provide lighting for homes in areas where there is no electricity or unstable electricity.

The manufacturer said it still needed to improve some more features before it could launch UrJar. According to IBM, this device is not for commercial use. Instead, IBM hopes to be able to provide free equipment in "energy-poor" countries, where power shortages affect the quality of life of poor people.

In addition, UrJar also helps reduce the negative impact of electronic waste. Instead of throwing old batteries out to landfill, users can use it again. This is not a really eco-friendly solution like clean energy, but it can help keep technology waste out of control.
