In the 21st century, humanity has become an engine, participant, and witness of the revolution in the energy sphere. We harness renewable energy sources (RES) such as sun, wind, and water movement. In recent years we have begun to understand the importance of preserving the environment in which we live. One particular area of focus is the increasing use of electrified means of transport, this is set to become an important step forward in the goal of reducing inner city pollution.
In the whole technological chain of the power system, from production to the final consumer, the task of accumulating generated energy (including mobile energy, such as gadgets and electric vehicles) and its use has become increasingly critical towards achieving the goal of reducing carbon footprints. The most common energy storage element in production today is the lithium-ion battery (Li-ion).
Battery production takes place in special rooms now commonly referred to as “Dry Rooms”. The main criteria by which dry rooms are classified is in the low dew point (tdp) requirements, these dewpoints can currently range from minus 35.0˚C to minus 65.0°C.
Violations of parameters, particularly at critical stages of production such as electrolyte fill lead to a decrease in the quality of the Li-ion battery. To maximise product quality, microclimates are often created at critical production points, where the moisture level in the air should be close to zero as possible.
The next generation of batteries currently in design, are showing an increasing demand for even lower dewpoints of minus 75.0°C and below, as such energy consumption for maintaining the dry rooms will continue to form a significant part of the cost of producing lithium-ion batteries.
To minimise this production cost, drys room should be constructed in a manner to reduce infiltration to as low as practicable. Crucially the room air drying systems should be designed to be as energy efficient as possible and should be able to react quicky to changing external conditions. With these goals in mind, DT Group are focusing on the utilization of dual rotor desiccant dehumidifiers to provide continuous supply of low dewpoint air into the manufacturing spaces. These innovative designs are set to become the new benchmark across the battery industry.
The Desiccant Technology Group team is always ready to work with you to solve any problem and provide an energy efficient, reliable solution, with the goal of achieving the required microclimate in your DRY ROOM project.
