AI Customer ServiceA multi-scale transport theory dominated by the spatial scale to reveal the nature of lithium-ion transport in solid-state lithium batteries is proposed. Generalized design rules for improving ion-transport kinetics in solid electrolytes are established at microscopic, mesoscopic and macroscopic scales.
The performance of conventional lithium ion batteries (LIBs) is limited by their low cation transference number (t+), defined as the fraction of ionic conductivity imparted by the lithium ion rather than its counterion.
In 1994, Doyle, Fuller, and Newman demonstrated that Li + transference number plays an crucial role in lithium batteries . When tLi+ of SPEs is close to 1, the SPEs may show a significant improvement over other materials (tLi+ < 0.2) in terms of material utilization and energy density.
As the power source of electric vehicles, lithium-ion batteries are widely used in the field of energy storage due to their advantages of high energy density, high discharge current, and long service life .
This work opens the door for the rules and control of energy conversion in metal-air batteries, greatly accelerating their path to commercialization. Lithium-oxygen batteries (LOBs), with significantly higher energy density than lithium-ion batteries, have emerged as a promising technology for energy storage and power 1, 2, 3, 4.
Herein, a unique perspective is proposed to re-examine the ion-transport behavior in lithium conductors by tracing Li + at multi-scale, including microscopic, mesoscopic and macroscopic scales. The multi-scale ion-transport mechanisms and corresponding characterization techniques are analyzed in depth.
