Converting commercial MnO2 into Co-doped LiNi0.5Mn1.5O4 with adjustable disordered/ordered phase ratio by a quaternary molten salt

Confinement of ZIF-67-derived N, Co-doped C@Si on a 2D MXene for enhanced lithium storage

“…The demand for rechargeable lithium-ion batteries (LIBs) with high capacity and long cycle life has become increasingly urgent with the booming development of electric vehicles and portable electronics. 1–5 Si is regarded as one of the most promising anode candidates owing to its high theoretical capacity (4200 mA h g −1 ), low working voltage (0.2–0.3 V vs. Li/Li + ), and abundant reserves. 6,7 However, the large-scale industrial application of Si anodes has been hindered by critical problems including the huge volumetric change during lithium/delithiation cycles and the low electronic and ionic conductivity.…”
