silicon anode Technology
without compromise
For Li-ion Batteries
The Problem
Li-ion batteries are at their performance limit
Electric Vehicles

$30,000
$45,000
$60,000

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
Less Anode Means less mass

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

Cathode
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
TruSilicon
silicon nanofibers ("SiNFs")
Superior cycling endurance
scalability based on high throughput Platform manufacturing process
1/5th the cost of silicon nanopowder
