Electrochemical energy storage disassembly

What are electrochemical energy storage devices?

These electrochemical energy storage devices can be employed in combination with LIBs or alone. Furthermore, they present diversified, safe, and green alternatives for energy supply and promote the sustainable development of new energy.

Why is electrochemical energy storage important?

Abstract: With the increasing maturity of large-scale new energy power generation and the shortage of energy storage resources brought about by the increase in the penetration rate of new energy in the future, the development of electrochemical energy storage technology and the construction of demonstration applications are imminent.

What is the energy storage mechanism?

The energy storage mechanism includes both the intercalation/deintercalation of lithium ions in the electrode material and the absorption/desorption of electrolyte ions on the surface of the electrode material.

How ESC is removed from a battery?

However, the cell disassembly process was not the main subject in this research. The hard-casing battery cells were cut, and the ESC was removed in an automated process . In another case, an automated cutting of the casing was carried out by a custom device, and ESC was manually removed .

Is a cell disassembly process environmentally friendly?

Bi et al. [91, 92] developed a complete material recovery process for spent batteries, which was described as environmentally friendly and highly efficient, while generating minimal waste. However, the cell disassembly process was not the main subject in this research.

Should a cell be charged or discharged before disassembly?

Before disassembly, a cell must be charged or discharged to a defined state-of-charge (SOC). 12, 16, 17, 30, 34, 45, 69 – 71 From a safety point of view, a deep discharge (until an end-of-discharge voltage of 0 V) is desirable, since it lowers the energy content of the cell.
