Over the past decades, engineers and chemists have been working to develop increasingly advanced battery technologies that could help to meet the rising demands of the electronics industry. This has led to the emergence of new types of batteries, including all-solid-state batteries.
All-solid-state batteries (ASSBs) are battery cells that include a solid electrolyte situated between two electrodes. These batteries, particularly all-solid-state lithium-metal batteries (ASSLBs), can exhibit high energy densities and greater safety, addressing some of the limitations of conventional lithium-ion battery (LiB) designs.
Despite their advantageous properties, ASSLBs have not yet been deployed on a large scale. This is partly because the growth of Li dendrites and their high interface resistance can significantly impair their performance.
Researchers at University of Maryland recently introduced a new principle for designing safe and high energy ASSLBs. This principle, outlined in Nature Energy, could help to develop more powerful and reliable fuel cells for electric vehicles and large robotic systems.
