Sila Nano raises $70 million in funding for silicon-dominant battery anodes

Battery specialist Sila Nanotechnologies has received $70 million in Series D funding from Sutter Hill Ventures, Next47 (backed by Siemens), and Amperex. Sila Nano will use the funding for the development and commercialization of its silicon-dominant anodes. Overall, Sila has raised $125 million from investors including Bessemer Venture Partners, Chengwei Capital, Matrix Partners, Samsung, and In-Q-Tel (IQT). The company also partnered with the BMW group earlier this year.

“Changes in battery chemistry are generational, and Sila Nano is bringing the next one to market,” says Sutter Hill Ventures Managing Director Mike Speiser. “Sila has solved the hard scientific and engineering problems and is ready to rapidly scale up manufacturing to meet the enormous demand for better batteries. Dramatically better batteries will change the landscape of what’s possible for the phone in your pocket, the cars on the road, and the entire grid infrastructure.”

“Batteries are a key component in the future of mobility and electrification, but the current technology can’t keep up,” said Next47 Partner T.J. Rylander. “Future progress in everything from wearables and smart devices to industrial IoT and electric transportation depend on improvements in energy density and cycle life. Sila has demonstrated that it has the right technology and the right team to meet these demands.”

“We have spent the past seven years diligently developing critical new materials to improve battery storage capacity. With the chemistry proven we are now moving into a new phase of market application and manufacturing at industry scale,” said Sila Nano CEO Gene Berdichevsky. “We are incredibly gratified to be supported by a group of investors from finance and industry who recognize the opportunity, understand the science and share our vision.”

    Promising to see developments like this….we are on the cusp of better batteries….

    • Michael B

      We’ve been getting better batteries every year for the past 15-20. Perhaps what you mean is that we’re on the cusp of an order-of-magnitude better batteries? Or a new battery chemistry with higher theoretical energy-density limits?

      • UnconventionalWisdom

        Ahh – yes. Sorry for my lack of precision in my statement. I am excited to see battery performance support transportation – on par in terms of cost (not quite there yet I believe) and single charge range. I know there are options out there like the Tesla products and others, but it is exciting to see improvements get us to better products.

    A little bit of background would be appropriate and appreciated. i.e., who the H is Sila Nano, how old are they (+what else do they do) and where are they located?

      Gleb Yushin is the CTO, he’s done battery research for the past 13 years at DrexelU, and GeorgiaTech. They are producing a battery anode that can replace the graphite in Lithium ion batteries, so if they can prove to get better results at a lower cost their anode will literally be everywhere in 10 years. They’re using silicone to absorb the lithium ions which typically swells 4x from absorption during charging but their using a nanocompiste to prevent that from happening. Here’s one of his patents that uses a silicone anode with a method for manufacturing:

      Instead of complaining about idiotic journalists why don’t you do your own research!

      • Michael B

        Uh, because it’s their job, not mine? Most “articles” I read are to save my time, with my silly assumption being that THEY did the appropriate research. WhatEVer.

        • Pavel Lelyukh

          Save time on what? I considering reading any news generally a waste of time, even some research papers on google scholar.

          • Michael B

            Save time compared to “doing my own research”, as you suggested. But you’re right about most news… Why do I keep hoping that’ll change?!

    A little more details would make this article a lot better. Like energy density, charging rates, life expectancy, etc. Talk talk talk doesn’t do much for me.
