Apple Supplier TDK Unveils Breakthrough in Batteries with 100x Boost in Energy Density for Wearable Devices

Japanese electronics manufacturer TDK announced a significant development in solid-state battery technology, aimed at enhancing the performance of wearable devices. The company has created a new material that increases the energy density of these batteries by a hundredfold over their existing solid-state batteries. This innovation could lead to smaller, faster-charging batteries with extended lifespans, suitable for devices like wireless earphones, hearing aids, and smartwatches. Composed of an all-ceramic material, these batteries are designed to be extremely safe and compliant with EU regulations, potentially replacing traditional coin cell batteries.
