Maintaining accurate humidity control is essential to the production of lithium-ion batteries, and the most effective way to do that is to remove the moisture from the desiccant. Although dehumidifiers may look the same on the outside, it's what's on the inside that counts. In fact, not all components and construction methods are the same, and those differences can have a huge impact on performance – from wasted energy, to poor performance and ultimately high and inconsistent humidity levels.
