Cabot Launches First Graphene-Based Additive to Improve Energy Density of Lithium-Ion Batteries
LITX™ G700 graphene-based additive delivers step change performance vs. conventional additives for energy batteries
Battery developers for applications in electronics and electric vehicles have reached the limit in reducing the loadings of conventional carbon additives. As a result, many are resorting to alternatives such as carbon nanotubes that add significant cost as well as manufacturing challenges.
The LITX G700 conductive additive is a graphene-based additive designed for use in electric vehicle and high-end consumer electronics in which better driving range and longer run times are critical performance features. This new additive is designed to deliver the conductivity needed to achieve very high energy densities in lithium-ion batteries at ultra-low loadings in comparison to conventional additives. Less loading or volume allocated to conductive additives enables more volume to be available for energy storage materials. As a result, the LITX G700 graphene-based additive delivers step change performance in conductivity at ultra-low loadings and is easily incorporated into battery electrodes.
“Cabot is committed to becoming the key performance additives supplier
to the lithium-ion battery industry,” said
Graphene is a thin sheet of carbon atoms that has high electrical and thermal conductivity, and is mechanically strong. It is used as a performance-enhancing material in composites to add strength, stability, electrical and thermal conductivity, and other properties at lower loading levels than traditional materials. Its unique shape and structure provide different application opportunities from standard carbon additives. Specifically, graphene’s unique properties help to balance the overall electronic and ionic conductivity of lithium-ion battery cells that could not be achieved with other carbon additives.
“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
