| Abstract | High-value recycling of photovoltaic silicon waste is an important path to achieve "carbon neutrality." However, the current remelting and refining technology of Si waste (WSi) is tedious with high secondary energy consumption and repollution, and it can only achieve its relegation recycling. Here, an efficient and high-value recycling strategy is proposed in which photovoltaic WSi is converted to high energy density and stable Si nanowires (SiNWs) electrodes for lithium-ion batteries (LIBs) in milliseconds. The flash heating and quenching (approximate to 2100 K, 10 ms) provided by an electrothermal shock drive directional diffusion of Si atoms to form SiNWs within the confined space between graphene oxide films. As a result, the SiNWs self-assemble to form a conductive SiNWs-reduced graphene oxide composite (SiNWs@RGO). When applied as a binder-free anode for LIBs the SiNWs@RGO electrode exhibits an ultrahigh initial Coulombic efficiency (89.5%) and robust cycle stability (2381.7 mAh g(-1) at 1 A g(-1) for more than 500 cycles) at high Si content of 76%. Moreover, full LIBs constructed using the commercial Li[Ni0.8Co0.16Al0.04]O-2 cathode exhibit impressive cycling performance. In addition, this clean high-value recycling method will promote economic, environmentally friendly, and sustainable development of renewable energy. |
