Mapping of Lithium-Ion Battery Electrolyte Transport Properties and Limiting Currents with In Situ MRI

Given the electrochemical modelling and control systems challenges facing lithium-ion batteries in extreme operating conditions, such as low temperature and high C-rate, it is important to understand the transport dynamics in a polarized cell with large electrolyte concentration gradients. To this end, a combination of conventional magnetic resonance imaging (MRI) experiments and MRI experiments coupled with pulsed-field gradient NMR for …
