Addionics developed a brand new foil present collector
Common Motors’ GM Ventures backed Addionics with funding
Addionics plans to construct a manufacturing facility within the U.S.
A startup goals to make EV batteries cheaper by specializing in an oft-overlooked battery part.
Addionics, which is backed by Common Motors’ GM Ventures venture-capital arm, has developed a brand new foil present collector, updating a part that “hasn’t modified a lot in 30 years,” CEO Moshiel Biton mentioned in a not too long ago revealed interview with TechCrunch.

Present collectors assist collect ions in battery cells, a course of Addionics believes could be improved by creating aluminum and copper foils with tiny holes and undulating peaks and valleys. The thought of including texture to enhance present collectors is not new, but it surely hasn’t been commercialized at scale, Biton claims.
Foil materials is made wavy and porous utilizing strategies from the semiconductor business. Addionics makes use of electroetching on the aluminum foil for battery cathodes. For the copper foil used for anodes, the startup makes use of electrical energy to deposit copper ions in a given configuration.

The result’s a three-dimensional present collector that’s straightforward to fabricate, whereas enhancing battery-level effectivity (already very excessive for EV batteries) and—most notably right here—probably doubling lifespan, Addionics claims. Whereas Goldman Sachs earlier this 12 months declared that EV battery costs are within the midst of dropping by 40%, some automakers like Toyota declare battery costs must lower additional to make EVs really inexpensive.
The startup introduced earlier this 12 months that it was planning to construct a $400 million U.S. manufacturing facility, and has additionally mentioned it has letters of intent from unnamed automakers. As TechCrunch notes, sourcing battery supplies from Addionics’ U.S. manufacturing facility might assist automakers meet federal EV tax credit score necessities for domestically-sourced content material.
