SiOx Encapsulated in Graphene Bubble Film: An Ultrastable Li‐Ion Battery Anode

SiO is proposed as one of the most promising anodes for Li‐ion batteries (LIBs) for its advantageous capacity and stable Li uptake/release electrochemistry, yet its practical application is still a big challenge. Here encapsulation of SiO nanoparticles into conductive graphene bubble film via a faci... Full description
