摘要
为了提高LiNi_(1/3)Co_(1/3)Mn_(1/3)O_(2)/Li_(4)Ti_(5)O_(12)全电池的电化学性能,本文通过对比实验,研究了在不同的N/P比以及充放电电压区间下的全电池性能表现。经对比数据发现,当正极材料LiNi_(1/3)Co_(1/3)Mn_(1/3)O_(2)(NCM111)和负极材料Li_(4)Ti_(5)O_(12)(LTO)的N/P比为1.0:1.0,充放电电压区间为0.5~3.2V时,电池具备较好的比容量、库伦效率和循环稳定性。本文为后续LiNi_(1/3)Co_(1/3)Mn_(1/3)O_(2)/Li_(4)Ti_(5)O_(12)全电池的工业化制造提供了帮助。
In order to improve the electrochemical performance of LiNi_(1/3)Co_(1/3)Mn_(1/3)O_(2)/Li_(4)Ti_(5)O_(12) batteries,this paper studies the performance of LiNi_(1/3)Co_(1/3)Mn_(1/3)O_(2)/Li_(4)Ti_(5)O_(12) batteries under different N/P ratios and charge-discharge voltage ranges.After comparing the data,it is found that when the N/P ratio of the positive electrode material LiNi_(1/3)Co_(1/3)Mn_(1/3)O_(2)(NCM111)and the negative electrode material Li_(4)Ti_(5)O_(12)(LTO)is 1.0:1.0,and the charge and discharge voltage range is 0.5~3.2V,the battery has good specific capacity,coulomb efficiency and cycle stability.This paper provides assistance for the subsequent industrial manufacturing of LiNi_(1/3)Co_(1/3)Mn_(1/3)O_(2)/Li_(4)Ti_(5)O_(12) full batteries.
