Positive electrodes for Li-ion and lithium batteries (also termed “cathodes”) have been under intense scrutiny since the advent of the Li-ion cell in 1991. This is especially true in the past decade.
The influences of different technologies on electrode microstructure of lithium-ion batteries should be established. According to the existing research results, mixing, coating, drying, calendering and other processes will affect the electrode microstructure, and further influence the electrochemical performance of lithium ion batteries.
Due to the smaller capacity of the pre-lithiated graphite (339 mAh g −1 -LiC 6), its full-cell shows much lower capacity than the case of Li 21 Si 5 (0.2–2 μm) (Fig. 6b), clearly indicating the advantage of the Li-rich Li-Si alloy as a promising lithium-containing negative electrode for next-generation high-energy LIBs.
Electrode structure is an important factor determining the electrochemical performance of lithium-ion batteries. It comprises physical structure, particle size and shape, electrode material and pore distribution.
Lithium (Li) metal is widely recognized as a highly promising negative electrode material for next-generation high-energy-density rechargeable batteries due to its exceptional specific capacity (3860 mAh g −1), low electrochemical potential (−3.04 V vs. standard hydrogen electrode), and low density (0.534 g cm −3).
Chemical reactions can cause the expansion and contraction of electrode particles and further trigger fatigue and damage of electrode materials, thus shortening the battery life. In addition, the electrode microstructure affects the safety performance of the battery.
