Silicon is a promising anode material for high-performance Li-ion batteries as a result of its high theoretical specific capacity and elemental abundance. Currently, the commercial application of the Si-based anode is still restricted by its large volume changes during the lithiation cycles and low electrical conductivity. To address these
The diamond-wire sawing silicon waste (DWSSW) from the photovoltaic industry has been widely considered as a low-cost raw material for lithium-ion battery silicon-based electrode, but the effect mechanism of impurities presents in DWSSW on lithium storage performance is still not well understood; meanwhile, it is urgent to develop a strategy for
Since the batteries can be made in existing silicon wafer plants, XNRGI claims the cost of a battery factory can be reduced by 95 percent. The company has not revealed when its new battery format

Here, we demonstrate that surface-treated thin silicon wafers could serve as monolithic additive-free, electrolyte-free, and void-free electrodes that can achieve high areal capacity at room temperature (∼25 °C). A dense solid electrolyte interface could effectively suppress the cracks and pulverization found in the liquid electrolyte. We

Silicon Joule™ technology replaces the lead-grid and cell connecting, lead-strap material inside a traditional lead battery with a treated silicon wafer. Gridtential is licensing the technology, enabling manufacturing
Solid-state battery research has gained significant attention due to their inherent safety and high energy density. Silicon anodes have been promoted for their advantageous characteristics, including high volumetric capacity, low lithiation potential, high theoretical and specific gravimetric capacity, and the absence of lethal dendritic growth.
Abstract Silicon–air battery is an emerging energy storage device which possesses high theoretical energy density (8470 Wh kg−1). Silicon is the second most abundant material on earth. Besides, the discharge products of silicon–air battery are non-toxic and environment-friendly. Pure silicon, nano-engineered silicon and doped silicon have been found
Si anodes promise high energy density but face lifespan challenge due to massive volume expansion during cycling. We identify "mechanical shutdown" in separators as a hidden culprit for cycling decay. By designing a high modulus separator, we significantly improve the stability of Si full cells.
