New 3D polymeric structure combines lightweight properties with high energy density to enhance lithium metal batteries

https://techxplore.com/news/2024-05-3d-polymeric-combines-lightweight-properties.html

"3D polymeric structure facilitating lithium-ion transport... more even lithium-ion distribution improving lithium metal anode capacity, performance, reducing dendrites... polyvinyl alcohol with high affinity for lithium ions, combined with single-walled carbon nanotubes, nanocarbon spheres... >5X lighter enabling uniform lithium electrodeposition... high stability after >200 charge-discharge cycles, energy density 344 Wh/kg... tested using pouch cells, not lab-scale coin cells, so strong potential for commercialization"
