Prediction of battery storage ageing and solid electrolyte interphase property estimation using an electrochemical model

Prediction of battery storage ageing and solid electrolyte interphase property estimation using an electrochemical model

Ageing prediction is often complicated due to the interdependency of ageing mechanisms. Research has highlighted that storage ageing is not linear with time. Capacity loss due to storing the battery at constant temperature can shed more light on parametrising the properties of the Solid Electrolyte Interphase (SEI); the identification of which, using an electrochemical model, is systematically ...

Simulating Li-ion battery ageing through solid electrolyte interphase growth in graphite/NMC cells

Artificial solid electrolyte interphase for aqueous lithium energy storage systems

Aqueous lithium energy storage systems address environmental sustainability and safety issues. However, significant capacity fading after repeated cycles of charge-discharge and during float charge limit their practical application compared to their nonaqueous counterparts. We introduce an artificial solid electrolyte interphase (SEI) to the aqueous systems and report the use of graphene films ...

Electrolyte and Solid-Electrolyte Interphase Layer in Lithium-Ion Batteries

The supply and the management of the energy are particularly at the centre of our daily concerns and represent a socio-economic priority. Indeed, while cars use fossil fuel as the main source of energy for over a century, the depletion of the oil reserves and the necessity to reduce the carbon dioxide emissions, stimulate the development of electric vehicles. Therefore, one of the main challeng...

An all solid-state electrochemical electrolyte analyzer.

Ion-selective electrodes have been applied to analysis of blood electrolytes with some success. However, currently available ion-selective electrode systems tend to be elaborate and expensive. We describe a clinical electrolyte analyzer in which inexpensive ion-selective electrodes are used. The elec‘trodes are in the configuration of thin wires and are all solid in construction. They may be di...
