For electric vehicles to be competitive, batteries must reach both:

But improvements
have been leveling off.

The good news:
a step-up change in performance is available thanks to one of the most abundant resources on earth.
Silicon.

Silicon
4,200 mAh/g
Graphite
375 mAh/g

Silicon can hold energy 10X better than graphite, the standard anode material.

This lets us make batteries with thinner electrodes for higher energy density.

So, while batteries are currently made this way:

Utilizing silicon in place of graphite is a notoriously difficult problem. A successful integration is akin to solving a Rubik’s Cube – achieving one trait compromises others and requires fine tuning that most material companies do not have.

Many material companies claim to have a “drop-in” solution, in the form of a revolutionary silicon powder. However, they ignore the complexity and complication of integrating silicon powder into an actual cell. They leave that problem for someone else to figure out.

We tackle silicon’s numerous issues using surface functionalization technology. This heavily patented platform technology allows us to controllably alter silicon’s properties at its most intimate interfacial dimension—the surface where it meets electrolyte and lithium. This allows us to influence the interaction with the other materials in the anode, and also optimize its performance in the cell in ways that were previously cost-prohibitive.
