Group14 has secured a $400 million investment from Porsche that will help build a new factory for its silicon-anode batteries.The battery breakthroughs that will make the EV revolution possible are coming from places you never heard of. You know about QuantumScape and StoreDot, but what about Group14 Technologies? That’s a company that says it has found a way to make battery anodes using silicon.
Others are working on silicon anodes but say they are years away from commercial production. Rick Luebbe, co-founder and CEO of Group14, tellshis company expects its first silicon-anode batteries to be fitted into electric cars as early as next year. Group14’s recipe, dubbed SCC55, uses “hard carbon-based scaffolding” to keep that silicon “in the most ideal form – amorphous, nano-sized, and carbon-encased,” according to the. In other words, the silicon sits in a minuscule scaffolding structure where it has room to expand and contract without weakening the structure of the anode, Luebbe explained.
Once the scaffold is made, the next step is called “Siligenesis.” It is how Group14 makes the silicon anode material. “Creating both silicon and tuned internal void spaces within the carbon scaffolding, this novel approach employs a non-exotic precursor that converts into silicon within the porous carbon scaffold.
