Innovation through the fusion of plasma science, battery science, and data science.

Incremental improvement in energy density of lithium ion battery have been led by moving toward high Nickel cathode and high capacity artificial and synthetic graphite alongside densified battery designs. In recent years, the view on potential innovation in energy density in lithium ion battery has been shifted to anode particularly to silicon and lithium metal. Silicon active materials or silicon anode itself can be made by different processes with different material designs such as core-shell, yolk-shell, scaffolding, compositing, binder free silicon anode, nanowire grown from pre-formed structure, and direct silicon deposition via PECVD. They all have both positive and negative impacts on battery performances because of different behaviours during lithiation and delithiation. LeydenJar silicon is a 100% silicon anode deposited on Copper foil directly by PECVD, which is unique in that it forms columnar structure of 100% silicon with pores inside and between columns. In the presentation, three topics will be touched upon; recent progresses in battery performance, how the unique features of LeydenJar technologies could have led to overcome the well-known fundamental issues of silicon anode; and how effectively the three technologies, plasma science, battery science, and data science, are fused in LeydenJar technologies.
