GM-Backed Addionics Promises Revolution in EV Battery Longevity and Cost with Novel Foil Current Collector

Startup supported by GM vows to reduce costs and extend the lifespan of electric vehicle batteries by concentrating on a frequently disregarded battery part.

Addionics, supported by General Motors' investment division GM Ventures, has innovated a fresh version of the foil current collector, a part that "has remained largely unchanged for three decades," according to CEO Moshiel Biton, in a recent conversation with TechCrunch.

Addionics contends that the efficiency of ion collection in battery cells can be enhanced by designing aluminum and copper foils that feature minuscule perforations along with a rippled surface of peaks and troughs. While the concept of texturizing current collectors to boost their performance isn't novel, Biton asserts that it has yet to be implemented on a large-scale commercial basis.

Utilizing methods from the semiconductor sector, the foil substance is crafted with a rippled and permeable texture. Addionics employs an electroetching process on the aluminum foil designated for the cathodes in batteries. Meanwhile, for the anodes' copper foil, the company harnesses electric currents to arrange copper ions in a specific pattern.

Addionics asserts that their innovative three-dimensional current collector not only enhances production simplicity and heightens the already significant efficiency of electric vehicle batteries but also remarkably promises to extend their durability by up to two times. Meanwhile, earlier in the year, Goldman Sachs announced a predicted 40% reduction in EV battery costs. However, car manufacturers like Toyota argue that battery costs must be further reduced for electric vehicles to be genuinely cost-effective for consumers.

Earlier in the year, the new company disclosed its intentions to construct a factory in the United States with an investment of $400 million. Additionally, it has indicated that it possesses preliminary agreements with certain undisclosed car manufacturers. TechCrunch highlights that obtaining battery materials from Addionics' American facility could aid car producers in adhering to the U.S. government's criteria for electric vehicle tax deductions, which mandate the use of materials sourced within the country.
