and greater Li+ ion diffusion coefficient for the LixFePO4/C electrode process. The Li+ ion concentration in LixFePO4/C is potential to impact the Li+ ion diffusion coefficient, and a decrease in the former results in an increase in the latter.Key words:lithium ion cell; LiFePO4/C; electrode process; electrochemical impedance spectroscopy; equivalent circuit; Li+ ion diffusion coefficient......
Diffusion barrier performance of nanoscale TaNx thin-film ZHOU Ji-cheng(周继承), CHEN Hai-bo(陈海波), LI You-zhen(李幼真) School of Physics Science and Technology, Central South University, Changsha..., and the diffusion barrier properties of TaNx thin-films is improved. TaN1.09 can prevent interdiffusion between Cu and Si effectively after annealing up to 650 ℃ for 60 s. The failure of TaNx is mainly......
