A transparent polymer electrolyte enables electrochromic fibers and fabrics to stretch, bend, and switch color with high contrast and fast response.
A hollow carbon fiber shell encloses lithium-alloyable metal nanoparticles to absorb anode swelling, maintain conductivity, and extend battery life.
Bundled single-walled carbon nanotubes help SiOx negative electrodes keep conductive pathways during volume expansion, improving capacity and cycle life.
Bundled single-walled carbon nanotubes help silicon-based anodes resist volume-change damage, maintain conductivity, and extend battery life.
Controlling porosity in silicon-lithium aluminate composite anode particles limits cracking and side reactions, improving efficiency and cycle life.
Side-bonded single-walled CNT bundles help silicon negative electrodes stay conductive during expansion and contraction, reducing cracks and capacity loss.
Electrospun textile-like battery assemblies use gel-polymer electrolytes and nanofillers to improve ion transport while limiting polysulfide loss.
Exposed outer electrode embedded member provides shortest electron path, eliminating high resistance from long tab travel distances.
