In previous work, Sayavong and his colleagues discovered that the SEI matrix begins to dissolve when the battery is idle. Based on that finding, the Stanford team decided to see what would happen if the battery was allowed to rest while discharged.
New lithium metal batteries with solid electrolytes are lightweight, nonflammable, pack a lot of energy, and can be recharged very quickly, but they have been slow to develop due to mysterious short circuiting and failure. Now, researchers at Stanford University and SLAC National Accelerator Laboratory say they have solved the mystery.
Series and parallel battery cell connections to the battery bank produce sufficient voltage and current. There are many voltage-measuring channels in EV battery packs due to the enormous number of cells in series. It is impossible to estimate SoC or other battery states without a precise measurement of a battery cell .
The passage of an electric current even when the battery-operated device is turned off may be the result of leakage caused , for example, by electronically slightly conductive residues of dirt on the battery surface, the battery holder, or mechanical and chemical processes inside the battery .
Reconnecting with the anode brings dead lithium back to life, enabling the battery to generate more energy and extend its cycle life. “Previously, we thought that this energy loss was irreversible,” Cui said. “But our study showed that we can recover lost capacity simply by resting the discharged battery.”
The culprit behind the degradation of lithium-ion batteries over time is not lithium, but hydrogen emerging from the electrolyte, a new study finds. This discovery could improve the performance and life expectancy of a range of rechargeable batteries.

The cover picture illustrates how state of charge (SoC) influences the capacity fade of a widely employed automotive Li-ion battery chemistry when idle, e.g. when EVs are parked. The chemical degradation is revealed to be aggravated when devices are kept at around 80 % SoC. Read the full text of the Article at
Lithium batteries are becoming increasingly important in the electrical energy storage industry as a result of their high specific energy and energy density.
