Positive electrodes processes during drying

A combined positive and negative DEP approach was used for positioning and assembly of the transistors. Negative DEP was used to position particles on top of metal electrodes. Positive DEP between the resistors and the metal electrodes led to assembly by either leaving the DEP voltage on or with the help of chemicals during drying process. 

The battery characteristic deteriorates when the rechargeable lithium-ion battery is contaminated with water. Naturally, it is desired that the water content in LiCoO used as the positive electrode-active material be controlled below a certain value. Moreover, currently a further decrease in the water content level is demanded by our customers. Although it may be considered that there is no problan because there is a process to make a slurry of the positive electrode-active material and to dry it, it is known that the water in LiCoO consists of both physical adsorption and chemisorptions. Because the water, which has been chemically adsorbed, cannot be removed during this drying temperature, it is important to stop the inclusion of moisture from the manufacturing process.
