摘要：
Introducing Mo into a Ni-rich layered cathode enables a Co-free Li-ion battery to cycle stably at 4.4 V, retaining 86% of its initial capacity after 1,000 cycles. The grain size refinement engendered by Mo increases the resistance to fracture by deflecting cracks while providing fast diffusion paths for Li ions.
