Batteries with more energy density could allow electric vehicles to travel longer on a charge. They could also enable lighter, thinner electronic gadgets. Because of this, many advanced battery makers are pursuing a jump in storage capacity with novel chemistries and materials.
EnerG2 said last week that its synthetic carbon anode increases the storage capacity of lithium-ion batteries by up to 30 percent. An anode is the negatively charged electrode in a battery, which attracts electrons as it discharges. The company has started production of its anode, which it hopes will appeal to lithium-ion battery makers.
The company’s technology, originally developed at the University of Washington, is a process for creating carbon with desired properties. Its first products were lead-acid batteries and components for ultracapacitors, two relatively small markets compared to the one for lithium-ion batteries.
