Understanding voltage fade in Li-rich batteries

Alt text coming shortly

In a new paper* published by Nature Materials, a team of researchers made up of Oxford Materials, Oxford Chemistry, The Faraday Institution and Diamond Light Source, examined Lithium (‘Li’) ion batteries made from a new Li-rich material to understand why their performance reduces after prolonged use.

Li-ion batteries are used in many household devices – your mobile, laptop, power tools, electric cars and solar panel back-up packs, but typically their performance drops the more you use them.  One reason for this is because the voltage is not as high as it was when the battery was new (this is known as ‘voltage fade’).  Future Li-ion batteries using Li-rich materials can last longer on a single charge than the ones you buy today, but their voltage fades much more quickly.
