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 limitations in potential for the electroactive material of the negative electrode are less important than in the past thanks to the advent of 5 V electrode materials for the cathode in lithium-cell batteries. However, to maintain cell voltage, a deep study of new electrolyte–solvent combinations is required.
More recently, a new perspective has been envisaged, by demonstrating that some binary oxides, such as CoO, NiO and Co 3 O 4 are interesting candidates for the negative electrode of lithium-ion batteries when fully reduced by discharge to ca. 0 V versus Li , .
The main problem is the high voltage (1.8 V) of the plateau, particularly as compared with carbon materials. Again this can be solved by combination with a sufficiently high potential positive electrode in a lithium-ion battery.
As the main body of lithium storage, negative electrode materials have become the key to improving the performance of lithium batteries. The high specific capacity and low lithium insertion potential of silicon materials make them the best choice to replace traditional graphite negative electrodes.
However, the use of lithium metal as anode material in rechargeable batteries was finally rejected due to safety reasons. What caused the fall in the application of rechargeable lithium-anode batteries is also well known and analogous to the origin of the lack of zinc anode rechargeable batteries.
