EnerG2

EnerG2, founded in 2003 in Seattle, Washington, developed its patented Carbon Technology Platform to enable large-scale production of carbon materials. They argue that their synthetic carbons can surpass the limitations of the naturally occurring carbons (such as those made out of coconut shells) traditionally used in energy storage applications. Polymer chemistry is the foundation for EnerG2's innovations. EnerG2 has developed laboratory-scale technologies and translated those technologies to commercial-scale manufacturing, all based on finely controlled and ultra-high purity polymer chemistry. The company aims through their products to tailor carbons for energy storage technologies in order to increase device utilization and performance to create better cost/performance value to the end consumer. The company manufactures its material through using a polymer to coat the silicon particles, then this material goes through a pyrolysis process that delivers a hard carbon structure - silicon composite. The company has a $28 million plant funded with a $21.3 million DOE Recovery Act grant opened in early 2012 and can now produce tens of tons of carbon materials a month, depending on demand.
