6.12: Battery characteristics

Metallic dendrites grow on the cells causing the electrodes to swell, forcing them closer together and increasing the self-discharge, The dendrites may penetrate the separator giving very high self discharge, or even a short circuit. Eventually, the internal impedance and the self discharge will be so high that the battery is no longer usable.

Nernst, Pourbaix and self-discharge

Self-discharge is the process by which a battery''s available capacity is spontaneously and irreversibly diminished by undesirable chemical reactions or electronic short circuits within the cell. Self-discharge occurs when the cell is disconnected and this differs from the loss of cell capacity when cell terminals are left connected

• Self-discharge rate: The battery''s self-discharge rate is the rate at which the battery loses its charge when it is not in use. If you have ever wondered why an electronic device does not turn on after a period of inactivity, this is because the battery self-discharged until the battery lost enough charge to no longer support device function.

6 FAQs about [Battery self-discharge diagram]

Can the Evans diagram be applied to self-discharge batteries?

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.

Can parasitic reactions cause self-discharge of rechargeable batteries?

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.

What is self-discharge in a battery?

Self-discharge is the process by which a battery’s available capacity is spontaneously and irreversibly diminished by undesirable chemical reactions or electronic short circuits within the cell.

How does self-discharge affect battery life?

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).
