The tiny ceramic-based lithium-ion battery can withstand heat and still operate at up to 150 degrees Celsius, making it a safer power source
2-MIN READ2-MINVictoria BelaPublished: 2:00pm, 23 Jun 2026Chinese 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.
The Tsinghua University-led team said the all-ceramic battery’s small size, high energy density, and safety could make it compatible with integration into next-generation technologies.
“The resulting batteries deliver stable, pressure-free operation across a wide temperature range … offering a safe and mechanically robust power solution for miniaturised electronics,” according to their paper published in the peer-reviewed journal Matter on June 5.
