Lithium batteries have always played a key role in the field of new energy sources.

Although batteries containing a Li metal anode offer the most promising energy density, they also face their own limitations regarding current density.

Nevertheless, uncontrollable dendrite growth and consequently large volume change during stripping/plating cycles can cause unsatisfied operation efficiency and

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.
Selecting a lithium-ion battery for a certain application depends mainly on the chemistry of cathode and other physical factors involved in the fabrication of cells, e.g. density of the material, composition and solid particle size in electrodes, and the cell geometry.
The practical uses of various lithium-ion batteries of different capacities often require the batteries being of adequate high-rate charge/discharge capability 24. Case 3 considers a 10 C discharge process. The simulated spatial distribution and temporal change of SOC in the anode and DOD in the cathode are depicted in Fig. 5 (a).
It has been shown previously 37 that high-rate discharges of Li-ion batteries are limited by species transport processes, which can be the Li-ion species transport in the electrolyte phase or the lithium transport in the solid active material phase or the both.
Improving Li + transference number is recognized as a non-negligible factor to enhance battery performance. In order to improve the lithium mobility number, three methods are commonly applied: enhancing dissociation of lithium salt, the construction of the framework, and the addition of additives and other aspects of improvement.
Main factors that retard the growth of lithium-ion battery include underutilization, stress-induced material damage, capacity fade, and possible occurrence of thermal runaway 5. Researchers have poured considerable endeavors to commercialize different types and/or chemistries of lithium-ion batteries.
