Company Overview

Ionobell, founded in 2017 in San Jose, California, develops next-generation silicon-based battery solutions for automotive and consumer electronics. The company’s mission is to deliver scalable, cost-effective, and sustainable energy storage by integrating porous nano-silicon anodes—offering up to 50% greater energy density—in existing manufacturing processes without overhauling facilities.

Battery Technology

Silicon-dominant anodes using porous nano-particle silicon with protective coatings to mitigate volumetric expansion. Offers ~50% higher energy density than graphite electrodes. Adaptable to existing battery manufacturing lines, reduces production costs by ~30% per kWh, sources recycled silicon from industrial byproducts, and employs a licensing model. Research ongoing into lithium-sulfur and solid-state platforms.

Products

Licensing agreements for silicon-dominant battery technology providing energy-dense, durable cells for electric vehicles and high-drain electronics. Specific product models and specifications have not been publicly disclosed.

Recent Projects

Partnerships and pilot programs with automotive OEMs and technology manufacturers to license Ionobell’s silicon battery technology, with ongoing efforts toward mass adoption in consumer and industrial applications.

Investors

In March 2024, ionobell raised a $3.9M seed extension, bringing its total seed funding to $7.3M. The round was led by Dynamo Ventures, Trucks VC, and Alumni Ventures, with funds allocated to scaling production, factory integration, and R&D.
