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.
Figure 2 outlines the range of causes of degradation in a LIB, which include physical, chemical, mechanical and electrochemical failure modes. The common unifier is the continual loss of lithium (the charge currency of a LIB). 3 The amount of energy stored by the battery in a given weight or volume.
The continuous SEI formation thickens the SEI and increases the internal resistance of batteries. Li deposition on anodes is an undesirable process, which occurs if the charge rate exceeds the speed at which Li + ions insert anodes. The poor Li plating/stripping efficiency in traditional carbonate electrolytes aggravates the irreversible Li + loss.
A reduction in the lithium content from the NE will lead to the SoC of that electrode decreasing whilst the PE remains the same. This is known as stoichiometric drift and leads to a reduction in the capacity but also an increase in the PE potential at the end of charge, accelerating the PE degradation mechanisms.
Whereas extensive research has been conducted to address capacity loss during extended cycling of lithium ion batteries , , , , , , , , , , the initial large capacity loss of the anodes of LIBs has been studied to a lesser extent.
It should be noted that the Li deposition is more prone to occur with high internal resistance of batteries. Electrode pulverization. The repeated lithiation/de-lithiation reactions associated with the volume variation of active materials, especially the alloy-type anodes such as Si, Ge, Sn etc., will lead to the electrode pulverization.
