Similarities between battery chemistries and causes of self-discharge are identified; concepts and ideas obtained this way are outlined. As an outcome of a better understanding of both common and system-independent causes and mechanisms of self-discharge as well as chemistry-specific processes approaches to reduce self-discharge are presented.
The rationality of applying the Evans Diagram to self-discharge batteries is adequate. In essence, as summarized in Table 2, both corrosion of metals and self-discharge of batteries are irreversible electrochemical reactions on a certain interface. Table 2.
(b) The self-discharge issues of lithium ion battery with the configuration of graphite/1M EC-DMC/LiNi 0.5 Mn 1.5 O 4 from irreversible electrochemical reaction at various sites (SEI/CEI formation, dendrite growth, active materials dissolution, corrosion of current collector).
For the first time, the self-discharge of rechargeable batteries induced by parasitic reactions is elucidated from the sight of the Evans Diagram, which is an effective method used in corrosion science for analyzing the coupled relationship between kinetics and thermodynamics.
For single cells, it would suppress the energy output due to the capacity loss, and the accumulation of undesired side reactions would result in excessive cation loss and shorten cycle life. For larger battery packs, the self-discharge will result in inconsistent charging states among cells during charge (Figure 1c).
Batteries are comprised of several components that allow batteries to store and transfer electricity. To charge and discharge batteries, charged particles (ions and electrons) must flow in particular directions and through particular components. Although batteries can vary depending on their chemistry, they have
