摘要
主要报道ZnMn2O4纳米颗粒的水热合成及其作为锂离子电池负极材料的电化学性能,并研究了新型水性粘结剂CMC-SBR对其电化学性能的影响。实验表明,所制备的ZnMn2O4粉体为单一的尖晶石晶体结构,呈纳米块状颗粒,粒径约为20 nm,且具有较好的循环性能和倍率性能;水性粘结CMC-SBR替代传统粘结剂PVDF能极大地改善其电化学性能。
Spinel type ZnMn2O4 nanocrystallines were successfully prepared by the hydrothermal method and their electrochemical performances were investigated as anode materials for lithium-ion battery.In addition,the effect of the water-soluble binder CMC-SBR on their electrochemical performances was studied.The results showed that the products with spinel structure were nanocystalline with diameters of about 20 nm.When evaluated as anode materials for lithium-ion battery,they had good cyclability and rate capability.In place of traditional binder PVDF,CMC-SBR had largely improved the performances of ZnMn2O4.
