Silicone is also used in solid state lithium batteries

Where is the problem?
when the solution to the problem already exists 

A team of NIMS researchers has taken another synthesis approach toward high-performance anodes for all-solid-state lithium batteries with commercial silicon nanoparticles. They found a unique phenomenon with the nanoparticles in the solid-state cell: Upon lithiation, they undergo volume expansion, structural compaction, and appreciable coalescence in the confined space between the solid electrolyte separator layer and metal current collector to form a continuous film, similar to that prepared by the evaporation process. The anode composed of nanoparticles prepared by spray deposition therefore exhibits excellent electrode performance, which has previously been observed only for sputter-deposited film electrodes. The spray deposition method is a cost-effective, atmospheric technique that can be used for large-scale production. Hence, the findings will pave the way for low-cost and large-scale production of high-capacity anodes for use in all-solid-state lithium batteries.

This is a fantastic revelation here in what you posted. I think shareholders need to understand what you just posted. You have a link to where you sourced this from?

  Following is a nice review of what Japan's NIMS (National Institute of Materials Science) & "Toyota" (Lasvegasnetwork listening?) have been collaborating on...hint: includes spray deposition of silicon nanoparticles. https://www.designnews.com/electronics-test/simpler-method-creating-high-performance-battery-anodes
