Tesla Acquires New Startup Shown In Silicon Anode Battery Patent
Tesla’s startup scouting abilities continue, as the American automaker has acquired Colorado-based startup SilLion, Inc., as shown in a new battery-based patent.

The rumours that Tesla was doing something in Colorado date back to late 2019 after the automaker began listing battery research jobs in the state.
Now we know why. Tesla has acquired startup SilLion, Inc., a Colorado-based battery company. We know this thanks to a new patent for a silicon-based battery anode. An anode that credits SilLion cofounders Daniela Molina Piper and Tyler Evans while Tesla is listed as the ‘Applicant.’
Tesla had previously hired multiple SilLion employees prior to this – which only fuelled the rumours of a Colorado-based R&D operation, to begin with.
The promising startup was working on high-energy batteries based on “high-loaded silicon anodes.” SilLion had received multiple grants from the Us Department of Defense and the US Department of Energy.
However, the company would later go dark in 2018. Here’s a brief description of SilLion’s work from its website – a site that has since been shutdown:
“The company’s technology delivers high-energy batteries by simultaneously incorporating high-loaded silicon anodes, nickel-rich NMC cathodes, and a non-flammable ionic liquid electrolyte and offer an increase in both energy density and specific energy in lithium-ion batteries, enabling users to get safer and lower-cost energy storage devices for defence, consumer electronics, and electric vehicle applications.”
This isn’t the first time Tesla has acquired a promising young startup for its battery knowledge. Earlier this year, the EV brand acquired Springpower for its cathode tech.
Earlier this week, Tesla was spotted shipping battery cell manufacturing equipment at its Giga site in Texas – otherwise known as the Gigafactory Texas.
Tesla’s next-generation 4680 battery cell is shaping up to be quite an improvement from the solid-state batteries used by other car brands. But what do you think? Leave us a comment down below.
