Sustainable eco‐friendly sub‐micron <scp>NaCl</scp> crystal powder‐assisted method to synthesize <scp>SiO_x</scp>/C as anode materials originated from rice husk for lithium‐ion batteries

Abstract In the present study, we produced SiO x /C from rice husk by NaCl sub‐micron crystal‐assisted synthesis method which can mitigate environmental degradation and hazards, simplify preparation, improve electrochemical performance. During synthesis, induces catalytic graphitization, carbon activation, amorphous silica formation. Moreover, it is only partially consumed be recrystallized reused indefinitely. Our crystal powder‐assisted created lithium‐ion batteries (LIBs) with husk‐derived anodes that exhibited a high initial charge/discharge capacity of 422.05/915.93 mAh∙g −1 at 0.05 A∙g current density stable cycling addition, electrode micro‐crystal had 333.96 density. By contrast, bare lower same condition. image
