The Finnish battery manufacturer has started full production at its new factory in Varkaus

Finnish battery manufacturer European Batteries Oy has started full volume production at its new factory in Varkaus, Finland. The factory was built by engineering and construction company, M+W Group.

The new factory has a surface area of 10,000m2 and manufactures large, lithium-ion based battery packs and systems with an annual production capacity of around 100 megawatt/hours. This means that around 3,000 full-electric cars can be fitted with lithium-ion batteries, although a possible tripling of production is already planned.

In July 2009, M+W Group began with the design and construction of cleanrooms and dry rooms for particularly sensitive phases of production. This includes the assembly of electrodes and separators as well as filling the individual cells with electrolyte at extremely low humidity. To ensure this, M+W Group used high performance absorption dehumidifiers, air locks and vapour-impermeable wall and ceiling systems.

M+W Group has developed a concept for planning and building lithium-ion battery plants, in which all the process stages are linked modularly under one roof. The multiple use of building infrastructure means that considerable cost savings can be achieved. For example, heat generated during individual process stages is used for air dehumidification and air conditioning.
