This review discusses efforts to improve lithium battery electrodes at various levels via: (1) the identification of the optimal chemical composition of active materials (AMs), (2) tailoring physical properties of AMs such as size and surface, and (3) integrating AMs with binders, conductive additives, and current collectors.
One of the major issues that has hindered step-change advances in LIB performance is the decline over time in the charge that a battery can deliver (defined as ‘capacity fade’), and its impact on performance. A key location for electrochemical degradation processes is the interface between the electrolyte and the electrode active particles.
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.
While much progress is being made to improve LIBs, other battery chemistries such as lithium–sulfur batteries (LSBs), Al-ion, Na-ion, and K-ion are also being explored [ 8, 9, 10, 11, 12, 13, 14 ]. In this short review, recent progress in improving the electrochemical performance and cycle life of lithium batteries is presented.
Lithium ions must be able to move freely and reversibly between and within the battery’s electrodes. Several factors can impede this free movement and can cause a battery to prematurely age and degrade its state-of-health (SoH). Over time, successive charging and discharging causes damage to the battery’s materials.
Both modes of lithium loss reduce the charge “currency” or lithium inventory, and thus the battery’s capacity, because there will be a diminished amount of lithium freely available to convey charge between the positive and negative electrodes.
