[资源] 3.22文献解读:三元材料在高能量密度锂离子电池中的应用

今天的文献解读时间定在11:30开始,欢迎大家一起参加,踊跃发言讨论。用到的文献简介如下:
题目:
An application of lithium cobalt nickel manganese oxide to high-power and high-energy density lithium-ion batteries
文献出处:Journal of Power Sources 174 (2007) 813–817
作者:Hiroshi Yoshizawa, Tsutomu Ohzuku
摘要部分:Evolved gas analysis (EGA) by mass spectroscopy (MS) was carried out for the pyrolysis of Li1−xCo1/3Ni1/3Mn1/3O2(185 mAh g−1 of charge capacity) and the results were compared with that of Li1−x CoO2(140 mAh g−1).
Electrochemically prepared Li1−xCo1/3Ni1/3Mn1/3O2clearly shows that O2 evolution begins at much higher temperature than Li1−x CoO2, suggesting that Li1−xCo1/3Ni1/3Mn1/3O2 is superior to LiCoO2 with respect to thermal stability.
High-temperature XRD measurements of charged LiCo1/3Ni1/3Mn1/3O2-electrodes at 4.45 V were also carried out and shown that the decomposition product by heating was identified as a cubic spinel consisting of cobalt, nickel, and manganese.
This indicates that phase change from a layered to spinel-framework structure plays a crucial role in the suppression of oxygen evolution from the solid matrix.
In order to show practicability of the new material, lithium-ion batteries with graphite-negative electrodes are fabricated and examined in the R18650-hardware.
The new lithium-ion batteries show high rate discharge performances, excellent cycle life, and safety together with high-energy density.
