In the pursuit of maximizing electric vehicle battery capacity, automakers are increasingly turning to silicon, a readily available but delicate ingredient that promises to increase capacity by at least 20%.
Companies like Sila, Group14, Envoix, and Amprius are all vying to commercialize their silicon anode technology in order to meet the growing demand for extended EV range.
Ionobell, a seed-stage startup, aims to lead the pack by offering a silicon material that is more cost-effective than its competitors.
Unlike traditional methods used by Sila and Group14, Ionobell takes a unique approach by starting with a porous silicon structure and then coating it, as outlined in the company’s patents.
Ionobell’s CEO, Robert Neivert, explains that their innovative technology keeps the silicon from swelling, allowing for greater lithium ion capacity without the risk of structural damage.
While silicon can accommodate 10 times more lithium ions than graphite, its fragility has limited its adoption in EV batteries. Ionobell’s cost-efficient approach utilizing waste materials helps lower overall production costs, providing a competitive edge in the market.
Despite initial skepticism, Neivert eventually joined Ionobell as CEO after witnessing the team’s progress in overcoming manufacturing challenges. The company recently secured a $3.9 million seed extension led by Dynamo Ventures and Trucks VC.
As competition heats up with industry giants like Group14 and Sila gearing up for commercialization, Ionobell faces obstacles in proving the viability of their technology to potential automotive partners.
However, Ionobell’s potential for cost savings could pave the way for broader adoption in the market, as the next phase of lithium-ion innovation, driven by silicon-based advancements, approaches.
