Apple Supplier TDK Announces Breakthrough in Battery Technologies

TDK Develops Material for High-Performance Solid-State Batteries

Japanese electronic components manufacturer TDK announced on Monday that it has successfully developed a material for its solid-state batteries, which it describes as a breakthrough that could significantly enhance the performance of wearable electronic devices.

Based in Tokyo and a supplier for Apple, TDK stated that the material for its small solid-state batteries has an estimated energy density of 1,000 watt-hours per liter, which is approximately 100 times higher than the energy density of conventional mass-produced TDK solid-state batteries. Energy density refers to the amount of energy stored in a certain volume of space.

Solid-state batteries are considered a potentially groundbreaking technology as they can store more energy than lithium-ion batteries and charge faster. TDK noted that this innovative material can be used in various devices that come into direct contact with the human body, particularly for wireless earbuds, hearing aids, and smartwatches. It is expected that the batteries will be made from a ceramic material with a solid electrolyte based on oxide and lithium alloy anodes.
