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 difficult challenges to overcome.
Improving the Performance of Silicon-Based Negative Electrodes in All-Solid-State Batteries by In Situ Coating with Lithium Polyacrylate Polymers In all-solid-state batteries (ASSBs), silicon-based negative electrodes have the advantages of high theoretical specific capacity, low lithiation potential, and lower susceptibility to lithium dendrites.
During the initial lithiation of the negative electrode, as Li ions are incorporated into the active material, the potential of the negative electrode decreases below 1 V (vs. Li/Li +) toward the reference electrode (Li metal), approaching 0 V in the later stages of the process.

The Li- and Mn-rich layered composites are used which have two layered structures as well as the Ni-rich lithiated transition metal oxide of Ni, Mn, and Co are used for improved performance. Electrochemical storage batteries are used in fuel cells, liquid/fuel generation, and even electrochemical flow reactors.
The demand for lithium batteries with energy densities beyond those of lithium-ion has driven the recent studies on lithium metal anode. High-efficiency electrochemical cycling of lithium requires improved lithium deposition morphology and reduced parasitic reactions between lithium and the liquid electrolyte.
