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.
Currently, in particular the automotive industry is focusing on the solid-state battery for electric vehicles. New materials and manufacturing processes are needed for the development of rechargeable batteries based on solid-state technology, in which solid instead of liquid electrolytes are used.
Solid-state batteries (SSBs) can potentially enable the use of new high-capacity electrode materials while avoiding flammable liquid electrolytes. Lithium metal negative electrodes have been extensively investigated for SSBs because of their low electrode potential and high theoretical capacity (3861 mAh g −1) 1.
Metal negative electrodes that alloy with lithium have high theoretical charge storage capacity and are ideal candidates for developing high-energy rechargeable batteries. However, such electrode materials show limited reversibility in Li-ion batteries with standard non-aqueous liquid electrolyte solutions.
The study revealed significant mechanical evolution of the electrode materials, including early comminution, crack initiation and patterning, irreversible volume changes, formation of a fresh SEI at the crack surface, and particle insulation .
These results demonstrate the possibility of improved all-solid-state batteries via metallurgical design of negative electrodes while simplifying manufacturing processes. Aluminum-based negative electrodes could enable high-energy-density batteries, but their charge storage performance is limited.
