Nexeon claims Li ion capacity record
Imperial College spin out Nexeon claims it has developed lithium ion battery cells with a capacity of 3.2Ah, said to be more than the capacity of the best commercially available Li-ion batteries. Cycle life performance is also said to exceed that of the best commercial cell when tested under the same conditions.
"These performance figures show how the use of silicon allows us to break through the capacity 'ceiling' for 18650 cells, which is seen with carbon-based anodes", said Dr Scott Brown, Nexeon's ceo. "It is a tremendous achievement and I'm immensely proud of our technical team. To have already exceeded the performance of cells made in volume by the world's best manufacturers gives us another huge confidence boost in the potential of our approach."
Nexeon's technology road map calls for it to deliver cells with a capacity of 4Ah next year, based on optimisation of first generation silicon anode materials.
