6 FAQs about [Battery Degradation Technology Project]

Do environmental and internal battery stresses degrade EV batteries over time?

The Faraday Institution's project is examining how environmental and internal stresses, such as high temperatures, charging and discharging rates, degrade electric vehicle (EV) batteries over time. Results will include the optimization of battery materials and cells to extend battery life (and hence EV range) and reduce battery costs.

What is the Faraday Institution's battery degradation Project?

The Faraday Institution ’s Battery Degradation project is led by the University of Cambridge, along with nine other universities and numerous industry partners. This project aims to study the mechanisms of degradation of lithium ion battery cells containing high Ni-content NMC and graphite.

Why is battery degradation important?

This improves the lifetime economics, enables longer warranties 4 and dilutes the environmental impacts associated with raw material extraction and manufacturing. 9,10 Understanding battery degradation is key to increasing operational lifetime.

How do you describe battery degradation?

Battery degradation can be described using three tiers of detail. Degradation mechanisms describe the physical and chemical changes that have occurred within the cell. Mechanisms are the most detailed viewpoint of degradation but are also typically the most difficult to observe during battery operation.

How does battery degradation cost affect the potential profit?

Depending on the battery degradation model used, battery degradation cost can considerably impact the potential profit if the battery's temperature is not controlled with adequate thermal management system. The empirical and semi-empirical models predict that the degradation cost is minimum at 5 • C and 25 • C respectively.

Which model predicts a minimum battery degradation cost?

The empirical and semi-empirical models predict that the degradation cost is minimum at 5 • C and 25 • C respectively. Moreover, both models predict degradation is minimum at lower battery charge levels.
