Bottleneck of battery development

How to break a capacity bottleneck?

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.

Is lithium-ion interfacial transport a bottleneck in all solid-state batteries?

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.

Can solid-state batteries increase lithium-ion battery energy density and safety?

Nature Communications 8, Article number: 1086 (2017) Cite this article Solid-state batteries potentially offer increased lithium-ion battery energy density and safety as required for large-scale production of electrical vehicles.

Why do solid-state batteries have a poor rate and cycle performance?

Despite providing a high bulk lithium-ion conductivity, the poor rate and cycle performance of solid-state batteries are ascribed to a high internal resistance for lithium-ion transfer over the solid–solid electrode–electrolyte interfaces 4, 5, 6, 7, 8, 9, 33, 34, 35, 36, 37, 38, 39.

Does electrode preparation and battery cycling influence lithium-ion transport?

Here we report two-dimensional lithium-ion exchange NMR accessing the spontaneous lithium-ion transport, providing insight on the influence of electrode preparation and battery cycling on the lithium-ion transport over the interface between an argyrodite solid-electrolyte and a sulfide electrode.

Can NMR detect lithium-ion transport over 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.
