Daimler-Backed Battery Startup Raises Funds, Hires Tesla Veteran.

04 November, 2019

Sila Nanotechnologies, a San Francisco Bay-area battery startup, is getting an additional $45 million in funding and has hired two new executives, including a former Tesla Inc. manager who helped build the electric-car company’s relationship with battery-cell makers.

Bill Mulligan, a former vice president at solar-panel maker SunPower Corp., joins Sila as its first chief operating office, the Alameda, California-based company said in a statement. Kurt Kelty, a former Panasonic Corp. and Tesla executive who then joined vertical-farming startup Plenty Inc., was named vice president of automotive.

The $45 million investment from Canada Pension Plan Investment Board brings the company’s total funding to $340 million, including an earlier contribution from Daimler AG. Daimler and BMW are automotive partners.

Sila is working to improve the performance of lithium-ion batteries, the key component of electric cars. Measured as kilowatt hours per kilogram or liter, energy density determines range: The more watt hours you have, the more miles the car can travel on a single charge. Low-cost, high-energy-density batteries are the holy grail.

The basic guts of a battery include a negatively charged anode, a positively charged cathode and the electrolyte. As a battery discharges, ions flow from the anode to the cathode, flowing through the electric circuit to releasing energy.
Sila is creating a silicon-based battery anode that’s fundamentally different chemistry than the graphite used in the most commercially popular anode material. Sila says its breakthrough can boost battery performance by 20%, which would be a big draw to original-equipment manufacturers in the auto industry.

“This will allow OEMs to build fundamentally different cars: smaller cars with longer range,” Chief Executive Officer Gene Berdichevsky said in an interview. Autos isn’t the only market he’s tackling: “We’ll be in wearables and phones before cars.”

Berdichevsky was employee No. 7 at Tesla, where he worked on the company’s first electric car, the Roadster, and was an entrepreneur in residence at Sutter Hill Ventures after he finished his graduate degree at Stanford University. He co-founded Sila Nano with the mission of commercializing a generational shift in battery chemistry.

When Kelty joined SoftBank-backed Plenty, he figured revolutionizing agriculture would be his next act, and he remains a believer in the company. But batteries have always been his passion, and he’s been on Sila’s advisory board for the past two years. Kelty worked with battery-cell makers on each Tesla vehicle from the Roadster to the Model 3.

“Batteries are all about trade-offs. With Sila, you get improved energy density without all the trade-offs,” said Kelty in an interview. “Let’s say a Tesla car gets 200 miles per charge and 1,000 cycles. If you can get 5,000 cycles with the same range, you are talking about a million-mile car. I’ve spent 25 years working toward this. It’s a natural fit for me.”


About Sila Nanotechnologies

The battery industry has been long on promises and short on delivery. At Sila, we’re changing that, and delivering actual material that works in actual full cells that you can test in actual real-world conditions. Our silicon-dominant anode products drop into existing battery manufacturing processes, replace graphite entirely, and deliver significantly higher energy density at the cell-level with lower swelling.

Sila products drop into the existing commercial battery manufacturing process. This means that our battery manufacturing partners can produce higher performing cells in their existing factories on existing production equipment. This also means that automakers and consumer products companies can continue working with their existing battery suppliers while seamlessly incorporating Sila’s materials technology into new products.
