On page 6701, a sustainable route from cheap metallurgical silicon to porous Si/SiO x nanowires is successfully demonstrated by J. Xiong, C. Yan, and co‐workers for high performance lithium ion batteries. With a surface oxide layer of suitable thickness, the huge volume expansion of Si during charge/discharge processes can be greatly accommodated, resulting in superior cycling performance and high reversible capacity.
