A Low-Cost and High-Capacity SiO _x /C@graphite Hybrid as an Advanced Anode for High-Power Lithium-Ion Batteries.

ABSTRACT: Silicon suboxide (SiO _x ) is one of the most promising anodes for the next-generation high-power lithium-ion batteries because of its higher lithium storage capacity than current commercial graphite, relatively smaller volume variations than pure silicon, and appropriate working potential. However, the high cost, poor cycling stability, and rate capability hampered its industrial applications due to its complex production process, volume changes during Li⁺ insertion/extraction, and low conductivity. Herein, a low-cost and high-capacity SiO _x /C@graphite (SCG) hybrid was designed and synthesized by a facile one-pot carbonization/hydrogen reduction process of the rice husk and graphite. As an advanced anode for lithium-ion batteries, the SiO
