Apple AirPods and Watches could soon see much longer battery life
TDK, the largest maker of smartphone batteries in the world, said Monday that it has successfully developed a material that could be used in a new battery with "significantly higher energy density" than its existing cells. Energy density refers to how much energy a battery can store relative to its size or weight. The material will be used in TDK's CeraCharge solid-state battery, which it says has an energy density of 1,000 watt-hours per liter - approximately 100 times more than its conventional solid-state battery.
These batteries use an oxide-based solid electrolyte, in contrast with the liquid electrolyte used in lithium-ion batteries that are widely found in electronic devices, making them "extremely safe." Solid-state batteries are smaller, charge faster, last longer, and have a lower risk of damage from temperature changes.
