To be used as a lithium-ion battery material, it is, however, not enough that the material has a high electronic conductivity and a high surface area. A good negative electrode material also needs to undergo a reduction during the lithiation step and an oxidation during the subsequent delithiation step.
For post-lithium batteries, carbon is still an opportunity as electrode materials, as hard carbons for anode purpose or as carbon fluorides as cathode one. Progresses in those fields will be rapid with the perfect mastery of electrochemical mechanisms and the use of characterization techniques coupled to galvanostatic cycling.
Summary and Perspectives As the energy densities, operating voltages, safety, and lifetime of Li batteries are mainly determined by electrode materials, much attention has been paid on the research of electrode materials.
Simultaneously, the term “lithium-ion” was used to describe the batteries using a carbon-based material as the anode that inserts lithium at a low voltage during the charge of the cell, and Li 1−x CoO 2 as cathode material. Larger capacities and cell voltages than in the first generation were obtained ( Fig. 1 ).
Ultimately, the development of electrode materials is a system engineering, depending on not only material properties but also the operating conditions and the compatibility with other battery components, including electrolytes, binders, and conductive additives. The breakthroughs of electrode materials are on the way for next-generation batteries.
In addition to lithium metal and carbon-based materials, a large number of alternative possibilities for the anode of the lithium-ion cell have been recently reported in the literature. The diversity in chemical elements and reaction mechanisms clearly demand a systematic study.
