A rechargeable lithium-ion batteries cathode LiNi0.5Mn0.5O2 with hollow nano/micro hierarchical microspheres (LNMO-HS) is prepared. LNMO-HS with diameters of about 1μm is composed of approximately 100nm primary nanoparticles. The initial discharge capacity of LNMO-HS cathode is as high as 181.5mAhg−1 at 1C between 2.5 and 4.5V. The corresponding capacity retention is 96.3% during 100 charge and discharge...
