This mini-review discusses the recent trends in electrode materials for Li-ion batteries. Elemental doping and coatings have modified many of the commonly used electrode materials, which are used either as anode or cathode materials. This has led to the high diffusivity of Li ions, ionic mobility and conductivity apart from specific capacity.
This leads to capacity degradation of lithium batteries, increased internal resistance, and poses potential safety hazards [4, 5, 6]. To mitigate the aging of lithium batteries, extend the battery’s service life, and enhance its safety performance, it is crucial to investigate the factors influencing electrode stress in lithium batteries.
The copper collector of graphitic negative electrodes can dissolve during overdischarge and form microshorts on recharge. Preventing this is one of the functions of the battery management system (see 2.1.3). The electrode foils represent inert materials that reduce the energy density of the cell.
