Une batterie chinoise qui dure 50 ans

China's Nuclear Battery Innovation: Power for 50 Years No Recharge Required! In a major leap in energy tech, Chinese company Betavolt has developed a nuclear battery smaller than a coin that's capable of delivering continuous power for up to 50 years without recharging or maintenance Powered by nickel-63 and encased in diamond semiconductors, this solid-state battery is radiation-safe, scalable, and functions in extreme temperatures (-60C to 120°C). While the current output is small (100 microwatts), the company plans to scale up to 1-watt and beyond, opening possibilities for use in applications like: - Medical Devices: Pacemakers and other implants benefit from a consistent power source, reducing the need for surgical replacements. - Aerospace: Satellites and space probes can operate longer without the need for battery replacements or recharging - Remote Sensors: Ideal for IoT environmental monitoring in hard-to-access locations ensuring continuous data collection - Micro-Robotics and Drones: Extends operational time for small robots and drones used in surveillance or xploration Regarding cost, producing the BV100 involves expensive materials and processes. For instance, 1 gram of nickel-63 costs approximately $4,000, making the current production of these batteries costly. However, as technology advances and production scales up, prices may decrease, potentially making them more accessible for broader applications Massive kudos to the @Amit Sengupta who created this amazing deep dive video into Betavolt's revolutionary new power storage product
