For optimal kinetics compatibility, the key to breaking the capacity bottleneck is maintaining the mass transport deep within the electrode, instead of just accelerating oxygen diffusion at the oxygen inlet. As a proof of concept, the capacity limit is boosted by 150% by introducing breathing channels on the separator side.
The limitations of today's lithium-ion batteries are one such bottleneck, casting doubt on the viability of widespread electrification. Developers face mounting pressure to push battery technology further — delivering more power, enhancing safety and speeding up recharging times.
The choice of battery technology and its influence on the demand for raw materials is only valid with regard to the study of a given metal, since the change of technology implies the need for an alternative, a substitute, for which criticality issues may exist too.
Using the Li 2 S–Li 6 PS 5 Br solid-state battery as an example, the present experimental results demonstrate that lithium-ion interfacial transport over the electrode–electrolyte interfaces is the major bottleneck to lithium-ion transport through all-solid-state batteries.
This work demonstrates the ability of exchange NMR between distinguishable lithium-ion sites in the electrode and the solid electrolyte to quantify unambiguously the amount and timescale of lithium-ion transport over the solid electrolyte–electrode interface in bulk solid-state batteries.
By leveraging the inherent regulatory ability of battery systems, the initial states of nucleation and transport kinetics are controlled. Specifically, a multi-field cross-scale model, combined with visualization techniques, is developed to provide a quantitative and intuitive understanding of the coupling of phase transition and species transport.
