The lithium metal negative electrode is key to applying these new battery technologies. However, the problems of lithium dendrite growth and low Coulombic efficiency have proven to be di cult challenges to overcome.
To improve further the energy stored per unit weight, employing Li metal as a negative electrode is an efficient strategy owing to the low atomic number (high specific capacity: 3884 mAh/g) and very low redox potential (−3.10 V vs. standard hydrogen electrode) of Li metal.
Thus, a lot of effort are paid to develop next generation materials for negative electrode for LIBs. Silicon is considered to be next generation anode material in lithium ion battery due to its high theoretical specific capacity of 4200 mAh g −1 4, low discharge voltage (~0.4 V versus Li + /Li), highly abundant resource and low toxicity.
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.
Mechanochemical synthesis of Si/Cu 3 Si-based composite as negative electrode materials for lithium ion battery is investigated. Results indicate that CuO is decomposed and alloyed with Si forming amorphous Cu-Si solid solution due to high energy impacting during high energy mechanical milling (HEMM).
