Storage technology - Polifibra offers innovative and individual film solutions

Electrochemical storage systems are becoming increasingly more important for the energy supply of high-performance smartphones, computers, power tools and electric vehicles as well as stationary storage of renewable energy. Here lithium-ion-batteries are of vital importance. Over the past few years this type of batterie, due to its high energy density has become the leading storage technology in almost all areas of application. Polifibra Folien offers innovative and individual solutions for this rapidly growing market: pouch film.

Pouch film, Pouch bag cell or Coffee bag cell

The smallest active component of a battery is the battery cell. Active components of pouch cells are inside a cover that is made of a composite film consisting of synthetic material and aluminium, the sides of which are heat sealed. Pouch film forms the outer cover of the batteries and is also called housing film or coffee bag.

With its hermetic packaging made of a synthetics-aluminium-composite film the pouch cell meets the criteria of high packing density with reduced installation space, excellent heat dissipation and minimal weight. Besides high-power density and easy scalability, compared to other types of cells, the low manufacturing cost recommend the application of this type of cell in the area of high-energy batteries.

Polifibra applies the highest standards to its highly refined pouch film. The quality of the sealed seam is the primary issue in regard to operating time as well as the safety of the cell. Upon cycling it needs to tolerate periodic stresses and withstand pressure fluctuations.

Individual film solutions

The term "pouch cell" encompasses a multitude of different designs and packings, cellular chemistry and applications. Polifibra Folien Handelsgesellschaft with its main office in Limburg a. d. Lahn, Germany develops individual solutions for optimum and efficient use of pouch film for and with its customers.

In each case pouch film should always be tailored to the specific application. For that reason, different product variations are manufactured to adapt the packing of the battery to the requirements of the application. Because of the many variation a close co-operation between manufacturer and expert for film is vitally important.

Polifibra Folien is your reliable and flexible European partner if you are looking for or would like to develop innovative and individual solutions for future storage technology.
