Abstract

The disclosure provides an electrode comprising a conductive foil (1), an active layer (5) and an insulating edge coating (6). The active layer comprises an active material, a binder and optionally a conductive additive. The insulating edge coating comprises a ceramic material and a polyurethane binder. The insulating edge coating comprises 5 to 40 wt% polyurethane binder and from 95 to 60wt% ceramic material and the polyurethane binder comprises a minimum 85 wt% block copolymer of polyether and polyurea. The conductive foil comprises a first region (2), a second region (3) and a third region (4), wherein the second region is located between the first and third region and the active layer is coated on the first region. The insulating edge coating is coated on the second region and overlaps (7) the interface between the active layer and the second region and the third region is not coated with active layer or insulating edge coating. The disclosure also provides a method for preparing the edge coating, and electrode assembly, a cell, a battery system and a vehicle comprising the electrode.
