First anode-free sodium solid-state battery
“Although there have been previous sodium, solid-state, and anode-free batteries, no one has been able to successfully combine these three ideas until now,” said UC San Diego PhD candidate Grayson Deysher, first author of a new paper outlining the team’s work. The paper, published today in Nature Energy, demonstrates a new sodium battery architecture with stable cycling for several hundred cycles.
News “Although there have been previous sodium, solid-state, and anode-free batteries, no one has been able to successfully combine these three ideas until now,” said UC San Diego PhD candidate Grayson Deysher, first author of a new paper outlining the team’s work. This work is both an advance in the science and a necessary step to fill the battery scaling gap needed to transition the world economy off of fossil fuels. During battery assembly the powder was densified under high pressure to form a solid current collector while maintaining a liquid-like contact with the electrolyte, enabling the low-cost and high-efficiency cycling that can push this game-changing technology forward.
