Abstract

Hollow spherical LiNi0.5Mn1.5O4 (LNMO) material was synthesized by a glucose-assisted hydrothermal method. The glucose was mainly used to control the morphology of LNMO. The initial discharge capacity at 1C was 124.6 mAhg−1. And even at 10C, 91.8 mAhg−1 could still be obtained. Moreover, its excellent structural stability ensures the integrity of the electrode and capacity retention of 95.1% could be obtained at 1C after 100 cycles. The results show that this unique hollow sphere-like structure can promote the transport of Li+ and improve lithium storage capacity. Therefore, we conclude that the addition of glucose has a great improvement in cycle stability and rate capability.
