The Power in Your Hand

How to charge your device:

STEP 1: Connect the charger’s USB plug to the port of an AC adapter.

STEP 2: Place your device on the charger, making sure it touches the pins.

STEP 3: Confirm the charging icon appears and wait until the battery is 100% full.

Following the manual to charge a device is simple, but the technology inside is the result of long development. Modern batteries are crucial for the efficient use of renewable energy, such as solar and wind power, by storing electricity until it’s needed. The basic science is fascinating; a battery consists of two ends and chemicals that react to produce power.

The history of batteries is a story of constant innovation. From early 19th-century models to today’s lithium-ion batteries, scientists like Akira Yoshino have made them smaller, safer, and more powerful, helping create a sustainable society.

The Path to a Better Battery

The lithium-ion battery (LIB) is a key technology today, thanks to the work of three Nobel Prize-winning scientists. Early versions were not very safe or stable, sometimes catching fire. A major step forward came when scientist Akira Yoshino decided to adopt an earlier idea but used a new material. This innovation cleared the way for the safe, practical LIBs we use in our phones and cars. The evolution of this technology is not over; there is still the possibility of many new discoveries.
