A Tsinghua University team has developed an all-ceramic micro lithium-ion battery that operates stably at up to 150 degrees Celsius.
The rechargeable solid-state battery is made from ceramic materials. Unlike traditional flammable lithium-ion batteries, it can withstand brief thermal shocks of up to 300 degrees Celsius without loss of performance.
The team said the battery’s small size, high energy density and safety make it suitable for integration into next-generation technologies. Their paper was published on June 5 in the peer-reviewed journal Matter.
“The resulting batteries deliver stable, pressure-free operation across a wide temperature range … offering a safe and mechanically robust power solution for miniaturised electronics,” the paper states.
