Engineers create a high performance all-solid-state battery with a pure-silicon anode

https://ucsdnews.ucsd.edu/pressrelease/meng_science_2021

"demonstrated a laboratory scale full cell that delivers 500 charge and discharge cycles with 80% capacity retention at room temperature... silicon anode... allowing much faster charge rates... while maintaining high energy densities... eliminated the carbon and the binders that went with all-silicon anodes... used micro-silicon, which is less processed and less expensive than nano-silicon... sulfide-based solid electrolyte... is extremely stable in batteries with all-silicon anodes"

Silicon Anodes Muscle in on Battery Technology
https://www.pnnl.gov/news-media/silicon-anodes-muscle-battery-technology "It swells so much that the anode flakes and cracks, causing the battery to lose its ability to hold a charge and ultimately to fail... scientists have witnessed the process for the first time... empty spaces in the silicon anode merge to form voids or gaps. These gaps translate to battery failure... This work offers a clear roadmap for developing silicon as the anode for a high-capacity battery... including original materials like coatings, new ways to make the devices, and a new electrolyte that increases battery life"
