Countless applications are driving the need to improve rechargeable battery performance on many levels. EVs require faster charging and higher energy density to give them the range and "quick fill-up" of gas-powered vehicles. Portable electronics and computing devices need the energy density to power brighter displays and higher performance processing architectures. All devices need to be safe under a myriad of conditions. Regardless of the application, battery technology is going to be under pressure to improve for years to come.
Carbon-based materials have long played a role in battery construction and performance. Countless initiatives have sought to leverage materials from graphite to graphene to carbon nanotubes to drive existing lithium-ion battery performance higher. Others have used advanced carbon materials as a key component of new technologies like lithium sulphur to create more robust cathode structures.
Regardless of the particular battery technology, carbon nanotubes have the potential to improve performance.
