6 FAQs about [Battery negative electrode material production equipment lubrication]

What are battery electrodes?

Battery electrodes are the two electrodes that act as positive and negative electrodes in a lithium-ion battery, storing and releasing charge. The fabrication process of electrodes directly determines the formation of its microstructure and further affects the overall performance of battery.

What is a battery electrode manufacturing procedure?

The electrode manufacturing procedure is as follows: battery constituents, which include (but are not necessarily limited to) the active material, conductive additive, and binder, are homogenized in a solvent. These components contribute to the capacity and energy, electronic conductivity, and mechanical integrity of the electrode.

How does electrode microstructure affect battery life?

Chemical reactions can cause the expansion and contraction of electrode particles and further trigger fatigue and damage of electrode materials, thus shortening the battery life. In addition, the electrode microstructure affects the safety performance of the battery.

How do different technologies affect electrode microstructure of lithium ion batteries?

The influences of different technologies on electrode microstructure of lithium-ion batteries should be established. According to the existing research results, mixing, coating, drying, calendering and other processes will affect the electrode microstructure, and further influence the electrochemical performance of lithium ion batteries.

Can dry electrodes reduce battery capacity?

By controlling the water content of dried electrodes, the researchers suggested that severe drying process would cause irreversible damage to the electrode microstructure, leading to a sharp decline in battery capacity. In contrast, the best electrochemical performance of the battery can be achieved by using mild drying process.
