5 Battery Startup Companies to Watch

2. Sila Nanotechnologies 

Total Funding: $980.5 million

Sila Nanotechnologies has developed a nanocomposite of covalently bonded nanostructures, with 50% of the material used being silicon, and the rest being an undisclosed material.

In addition, according to the CEO, the composite is housed in a porous scaffold so it expands and contracts without puncturing the coating. Among the company’s financial backers are the US Department of Energy, Sutter Hill Ventures and Canada Pension Plan Investment Board.
