Silicon anode solid-state batteries Research on solid-state batteries has focused on lithium metal anodes. Alloy-based anodes have received less attention in part due to their lower specific capacity even though they should be safer. Tan et al . developed a slurry-based approach to create films from micrometer-scale silicon particles that can be used in anodes with carbon binders. When incorporated into solid-state batteries, they showed good performance across a range of temperatures and excellent cycle life in full cells. —MSL

All-solid-state batteries (ASSBs) are viewed as promising next-generation energy storage devices, due to their enhanced safety by replacing organic liquid electrolytes with non-flammable solid-state electrolytes (SSEs). The high ionic conductivity...

drastically improved between 1st and 3rd generations, showing decreasing the cost of manufacturing while maintaining power efficiency. [2] More recently, highefficiency and low-cost hybrid organicinorganic halide perovskite materials have emerged as the most promising light absorber for the new generation of photovoltaics replacing commercially dominant polycrystalline silicon materials. [3][4][5][6][7][8] After demonstrating solid-state perovskite solar cells (PSCs) in 2012, [9] the volume of research for PSC has massively increased. Consequently, power conversion efficiency of PSCs has rapidly developed, currently exceeding 25%, surpassing Cu(In,Ga)Se 2 (CIGS) and cadmium telluride (CdTe), and approaching to single crystalline silicon solar cells.
