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).
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.
The unique structure of the electrode-separator assembly can be utilized in a multilayered configuration to enhance the energy density of batteries (Figure 5a). In contrast to conventional electrodes on dense metal foils, the electrode-separator assembly allows liquid electrolyte to permeate through pores of the electrode and separator.
Note that battery chemists name the electrodes (cathode/anode) based on the processes occurring on discharging; from here on, the positive (cathode) and negative (anode) will be referred to what they are on discharge and be simplified to oxide and graphite electrodes, respectively.
Furthermore, the electrode structure permeable to liquid electrolytes enables a multilayered cell configuration, which contributes to achieving a high areal capacity. A thick electrode is desired for the higher energy density of batteries because it minimizes the fraction of electrochemically inactive components.
This achievement is attributed to the innovative and persistent development of materials, particularly active materials. The initially adopted electrode materials, lithium cobalt oxide (LiCoO 2, LCO) and graphite have relatively low specific capacities of 140 and 372 mAh g −1, respectively.
