Solid-State Batteries Survive Thousands of Cycles After a Squeeze

Solid-state batteries survive thousands of cycles after a squeeze

A mechanical squeeze redirected lithium dendrites in solid-state batteries, preventing short circuits over thousands of cycles.

A tight squeeze could fix the biggest hurdle for solid-state car and gadget batteries

Solid-state batteries promised safer, faster-charging power, but microscopic dendrites keep triggering short circuits. Stanford researchers discovered that applying continuous mechanical pressure forces dendrites to grow harmlessly sideways, offering a simple engineering shortcut to bring next-gen batteries to EVs and mobile gadgets.

Solid state battery design charges in minutes, lasts for thousands of cycles

Researchers have developed a new lithium metal battery that can be charged and discharged at least 6,000 times -- more than any other pouch battery cell -- and can be recharged in a matter of minutes. The research not only describes a new way to make solid state batteries with a lithium metal anode but also offers new understanding into the materials used for these potentially revolutionary batteries.

Giving solid-state batteries a squeeze keeps them from short-circuiting

Lithium-ion batteries power transportation and grid storage and enable our digital lives, but these ubiquitous batteries require frequent recharging and can fail over time. To make batteries more reliable and longer-lasting, researchers are exploring how to replace liquids inside batteries with a solid ceramic material that could improve their performance.
