BATTERIES

Silver, copper and copper alloy foils, aluminium laminated foils.

Products

Copper foils: used in new generation lithium-ion batteries.
Silver foils: produced for special batte- ries requiring speific electrochemical re- actions.
Copper alloy foils: used in batteries that have to withstand extreme mechanical and thermal stress.
Aluminium laminated foils: used as multilayer casings to ensure cell safety.

Applications

Service

We accept orders for even the smallest production quantities and guarantee our customers fast and reliable delivery times. We offer customised solutions, designed and developed to express the proper characteristics and suit unique production cycles

Silver

Silver (up to 99.99% purity with impurity control in PPB); perfectly degreased surfaces suitable for coating

Thicknesses from 8 my; thickness tolerance up to +/- 3%; minimum width 1 mm

Plastic flanges available for each coil; coils also available in reduced widths; customised shapes available on request

Hard foils with HV> 75
Mechanical properties with narrow tolerance ranges for special applications.

Specular surface with very low roughness level; the absence of surface impurities guarantees the highest level of polishability; anti- scratch protection film available

Copper

Different types of copper available depending on the required properties

Thicknesses from 8 my; thickness tolerance depending on alloy type
