Cabot Launches First Graphene-Based Additive To Improve Energy Density Of Li-ion Batteries
LITX™ G700 is a conductive graphene-based additive that is to improve conductivity and achieve a high energy density in lithium-ion batteries at “ultra-low loadings” in comparison to conventional additives. Lower volume additives offer the advantage of more space in batteries for energy storage materials.
“Cabot is committed to becoming the key performance additives supplier to the lithium-ion battery industry,” said Gregg Smith, general manager of Cabot Energy Materials. “Our new graphene-based additive is bringing a new leading-edge material to the market. We have been working closely with our customers to help deliver solutions that will increase and extend the performance of their current and next generation battery cells.”
Graphene is a carbon-based material (often made from graphite) which exhibits a highly unusual combination of features such as high electrical conductivity, high thermal conductivity, rust resistance (it does not rust at all), malleability, semiconductor capabilities which enabled IBM to make a 155 GHZ transistor, strength far exceeding that of steel, and a weight 1/6th of that of steel.
“We recognize that graphenes have the potential to improve performance in a number of applications from advanced batteries to conductive plastics and tires. We see it also leading to new, stronger composite materials,” said Yakov Kutsovsky, chief technology officer. “Cabot has made and continues to make investments in graphene technology. This enables us to have a robust platform capability in which to test and further develop graphene materials.”
