Chinese scientists have developed a tiny, ceramic-based lithium-ion battery that can withstand extreme heat, offering a safer power source for smart sensors, aerospace gadgets and military applications. Unlike flammable traditional lithium-ion batteries, this rechargeable solid-state battery operates stably up to 150 degrees Celsius (302 degrees Fahrenheit) and can withstand brief thermal shocks of up to 300 degrees Celsius without compromising performance.
