6 FAQs about [Wet treatment of negative electrode materials for batteries]
What is a wet electrode manufacturing process?
The conventional wet electrode manufacturing process consists of mixing, coating, drying, calendaring, post-drying, and cell assembly steps, as shown in Fig. 1 [2, 3]. The wet process follows the essential step of a slurry formation consisting of active materials, binders, conductive additives, and solvents.
What is a wet electrode experiment?
In the wet electrode experiments, the battery is discharged to a capacity of 0% after the battery has run for ten cycles, and the negative electrode sheet with the SOC of 0% is peeled off by disassembling in an argon-filled environment. The positive electrode is disassembled for stripping when the battery SOC is 100%.
Why do batteries need a wet coating?
The wet coating also enables the production of thicker electrodes, resulting in higher energy–density batteries. However, using solvents in the wet coating can result in environmental and safety concerns, and the drying and pressing steps can increase the processing time and cost [16, 17, 18].
What is an electrode in a battery?
An electrode is where the electrochemical reactions throughout the charging and discharging process occur, which is a crucial part of a battery. As a vital part of a battery, an electrode is essential to the storage and discharge of the battery.
What is dry pressing a battery electrode?
While other methods can be used for wet and dry battery electrode technology, the dry pressing method includes using a hydraulic press to compress dry electrode material into the required shape and density. The electrode that results is then trimmed to the proper size and shape.
What is a dry electrode coating?
The dry electrode coating technology eliminates the need for solvents and drying steps, resulting in a more environmentally friendly and cost-effective process. The dry coating also allows for better control over the thickness and uniformity of the electrode, resulting in improved battery performance.
