Rechargeable Li battery based on the Li chemistry is a promising battery system. The light atomic weight and low reductive potential of Li endow the superiority of Li batteries in the high energy density. Obviously, electrode material is the key factor in dictating its performance, including capacity, lifespan, and safety [9].
Directly recycling the negative electrode material, specifically graphite, the most commonly utilized anode material in LIBs, has been less extensively investigated compared to the positive electrode. This is primarily attributed to its economical nature and the limited financial incentive associated with its recycling, even if natural graphite

We have developed a method which is adaptable and straightforward for the production of a negative electrode material based on Si/carbon nanotube (Si/CNTs) composite for Li-ion batteries. Comparatively inexpensive silica and magnesium powder were used in typical hydrothermal method along with carbon nanotubes for the production of silicon nanoparticles.

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.
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.
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.
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).
Lithium ions are embedded in the spent materials under the action of electric current. The capacity of spent materials after electrochemical repair is low (Table 3), which is likely to be due to the SEI film on the surface of the spent materials hindering the replenishment of Li, and lithium defects have not been completely repaired.
