Dual-confined SiO encapsulated in PVA derived carbon layer and chitin derived N-doped carbon nanosheets for high-performance lithium storage

SiOx anodes hold great promise for next-generation lithium-ion batteries (LIBs) due to the high capacity and enhanced cycling stability versus silicon. However, its long-term development is hampered by seeking a scalable and effective method to tackle the issues of low conductivity and large volume expansion. Herein, a novel anode material is constructed by wrapping SiOx into PVA derived carbon layer and N-doped carbon (NC) nanosheets derived...
