TDK, an Apple supplier, claims a major breakthrough in battery technology that could revolutionize small consumer electronics. They have developed new ceramic materials for batteries with 100 times the energy density of their current batteries, offering 1,000 watt-hours per liter. This breakthrough could lead to smaller device sizes, longer operating times, and safer battery technology. While solid-state batteries are seen as the future of energy storage, challenges in mass production remain, especially for larger battery sizes. Japanese companies like Toyota and Nissan are leading the charge in commercializing this technology for electric cars. However, skepticism remains about how quickly solid-state batteries can be realized due to durability and safety concerns.
