Cell ageing characteristics

Modelling battery cells at end of life is becoming more popular for key reasons, as Nick Flaherty reports. Accurate prediction of battery lifespan is crucial for e-mobility and involves a variety of test approaches, from thermal measurements to transmission electron microscopes. Assessing how a cell delivers power when required and how it is charged provides insights into its lifetime.

Battery dielectric protection

Peter Donaldson examines multi-function dielectric materials for battery systems. Dielectric protection materials are critical in EV battery systems, where they serve to insulate components from one another, reduce the risks to technicians working on them, and often also contribute to structural strength and thermal management.

End-of-line battery testing

As battery technology evolves, so the process of testing it all becomes more complex, as Peter Donaldson discovers. End-of-line (EOL) testing for EV battery packs is a critical step in ensuring their performance, safety and longevity, and that of the vehicles they power. As battery technologies evolve, so do the complexities of testing them.

NTO’s bus pass

Toshiba has developed a new generation of its fast charging SCiB battery technology, which combines a lithium-ion cathode with a niobium titanate oxide (NTO) anode, writes Nick Flaherty. SCiB Nb has an energy density of 350 Wh/L at 2.3 V while the chemistry minimises the risk of fires and explosions, and it is being used for the first time in an electric bus in Brazil. The cells
