TDK claims solid state battery breakthrough
Apple supplier says new tech has 100 times the capacity of its current batteries.
Japan’s TDK is claiming a breakthrough in materials used in its small solid-state batteries, with the Apple supplier predicting significant performance increases for devices from wireless headphones to smartwatches. The breakthrough is the latest step forward for a technology industry experts think can revolutionize energy storage, but which faces significant obstacles on the path to mass production, particularly at larger battery sizes. Kevin Shang, senior research analyst at Wood Mackenzie, a data and analytics firm, said that “unfavorable mechanical properties,” as well as the difficulty and cost of mass production, are challenges for moving the application of solid-state oxide-based batteries into smartphones.
