SLINTEC scientists are using carbon nanotube films to stop the growth of dendrites on lithium metal anodes. This step may help develop lithium metal batteries, which could have much higher capacity and faster charging than lithium ion batteries.
RENEWABLE ENERGY AND STORAGE SYSTEMS
With rapidly growing energy demands and concerns over energy security and environmental pollution, it is highly desirable to explore renewable and sustainable energy sources. Wind power and Solar photovoltaics (PV) are the world’s fastest growing renewable energy.
Graphene exhibits excellent mechanical, electrical, thermal and optical properties and is particularly suitable for the implementation in electrochemical applications because of extraordinary electrical conductivity, large specific surface area, unique heterogeneous electron transfer and charge carrier rates and good electrochemical stability. The SLINTEC spin-off company Ceylon Graphene Technologies’ high quality graphene is highly desirable for renewable energy and storage systems. As part of our contribution to the extensive research on lead acid batteries with added graphene ended up with 300% charge acceptance improvements and 200% cycle life improvements.
REVOLUTIONARY GRAPHENE AUTOMOBILE BATTERY LAUNCHED BY SLINTEC'S SPIN-OFF COMPANY CEYLON GRAPHENE TECHNOLOGIES
Ceylon Graphene Technologies launched first ever Graphene applied Lead Acid Battery Technology together with Associated Battery Manufacturers (Cey) Ltd, leader in the industry of battery manufacturing in the region. Mixed composites of Reduced Graphene Oxide and Expanded Graphite mixed in an optimized ratio have delivered promising results of enhanced charge acceptance of lead acid batteries while reducing sulfation in negative plates. This technology is ready to be applied in the mass production and soon to be available in the market by 2020 under the Lead Acid Battery range of Exide. The result optimisation using graphene and its derivatives expected to be further modified and extensive research is in progress.
