EV Vs gas.png
Range (Miles)
This prevents affordable EV range and the efficient management of energy for a multitude of applications
The Limiting Factor
It's basic chemistry
Carbon Anode

-

+

Cathode
The anodes of traditional li-ion batteries are made of carbon
It takes 6 carbon atoms to store 1 Lithium ion
The Solution
It only takes 1 silicon atom to store 4 lithium ions
That's a 24X advantage
over carbon

Vetted, Trusted and Verified
Silicon has been used commercially since 2009

Most of the silicon used is silicon nanopowder

Inherent compromise

silicon swells by 400% when charged
Swelling causes cracking in the anode
cracking is detrimental to the battery's service life

As a consequence
commercially available batteries only contain a small amount of silicon nanopowder

the benefits of Silicon aren't being maximized
The Advanced Materials Revolution
A handful of companies have developed alternatives to silicon nanopowder

They embody special properties to circumvent the detrimental effects of swelling

Their materials deliver sensational performance

But they're prohibitively expensive
and Their methods for making them are difficult to scale
Same problem, different Decade 
silicon nanopowder doesn't satisfy performance needs
and

Advanced alternatives are too expensive

Introducing

silicon nanofibers ("SiNFs")
Superior cycling endurance
