Abstract: Limited practical capacity and poor cyclability caused by sluggish kinetics and structural instability are essential aspects that constrain the potential application of Li2MnSiO4 cathode materials. Herein, Li2Mn1- xCa xSiO4/C nanoplates are synthesized using a diethylene-glycol-assisted… read more here.
