Why are step-change advances in lithium ion battery performance a problem?
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.
How to improve lithium mobility number?

What chemistries can improve lithium battery performance & cycle life?
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.
Can lithium ions damage a battery?
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.
How does lithium loss affect battery capacity?
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.
