Abstract
Sr_doped spinel phase_LiSrxMn 2-x O4 was successfully prepared by solid_state method. Structural and electrochemical characterizations were carried out. Although Sr 2+ has a large ion radius_1.12 ,the spinel structure can be well maintained for LiSrxMn 2-x O4 sample as far as the x value doesn't surpass 0.05. Electrochemical study presents supporting evidence that doping the stoichiometric LiSrxMn 2-x O4 phase with Sr is an effective way to improve the cycleability of LiSrxMn 2-x O4 spinel material. A remarkable enhancement of the cycleability with retention of the initial capacity >90 % after 95 cycles was observed for the Sr_doped spinel.
