Journal of the Electrochemical Society, vol. 162(2), pp A3038-A3044http://hdl.handle.net/10204/7973Copyright:2015 ECS.Spinel Li(sub4)Ti(sub5)O(sub12) has become an alternative material to replace graphite anodes in terms of solving safety issues and improving battery life-time. Unfortunately, as Li(sub4)Ti(sub5)O(sub12) is an insulator, the low electrical conductivity becomes a major drawback, as it is unfavorable to higher rate capability. In addition to the low electronic conductivity, severe gassing during charge/discharge cycles is a critical but often-overlooked problem of Li(sub4)Ti(sub5)O(sub12) batteries. Li(sub4)Ti(sub5)O(sub12)/C microspheres were prepared by assembling the nano-Li(sub4)Ti(sub5)O(sub12) (50–300 nm) with pitch derived pyrolytic carbon. It was found that the coated carbon in Li(sub4)Ti(sub5)O(sub12)/C microspheres can effectively inhibit gassing and Mn deposition in LiMn(sub2)O(sub4)/Li(sub4)Ti(sub5)O(sub12) battery. Carbon can also significantly improve rate capability and cycling performance compared with that of Li(sub4)Ti(sub5)O(sub12) microspheres without carbon due to stable interface and superior electronic conductivity.enSpinel lithium titanateElectrochemical half cellsCarbonMaterials ScienceArticleWen, L., Wu, Z., Luo, H., Song, R., & Lia, F.
