Before the process of recycling, the lithium battery needs to discharge the electricity. Without this step, the batteries may be explosive during the treatment. එබැවින්, for the safety of the working process, electricity discharge is necessary. In order to secure the process, the brine and inert gas can also help the discharge process.

After the electricity discharge process, the materials then need to conduct the drying process. The low-temperature drying oven plays the most important part of the process. The main purpose of the machine is to evaporate the electrolyte. Although the machine is called low temperature, the inside temperature still can reach 90℃-120℃. වියළීමේ ක්රියාවලියේදී, the oxygen content can be lower than 2% to reduce the risk of explosion.
