A UV curable dielectric coating is described. The curable coating can include one of more acrylate monomers, a urethane prepolymer, a crosslinker, at least one adhesion promoter, a photoinitiator, and optionally one or more fillers and/or additives. The coating can be used to insulate battery cells and battery packs, such as those used in electric vehicles. The coatings can be easily applied and quickly cured. The cured coatings can have high adhesion strength, even after exposure to wet conditions.

In order to create an electrochemical cell, comprising a housing, an electrochemical element arranged in an interior of the housing, and at least one cell terminal that comprises a terminal feed-through, which extends through a through-opening of the housing, which electrochemical cell is of simple construction and requires a low production expenditure but still reliably limits the short circuit current that arises in the case of a non-regular operating state, it is proposed that the electrochemical cell comprises an electrically conductive sealing element, which seals the through-opening of the housing and electrically conductively connects the cell terminal to the housing.

The aim of the invention is to provide an electrochemical cell that can be produced as simply as possible and has a long service life. This is achieved in that the electrochemical cell comprises a first contact element that connects a first cell terminal to a first connection conductor and that is fixed to a cover element of the electrochemical cell by means of a first potting element in a first connection region, said first potting element being made of a first polymer material that comprises or is made of a first resin material, and/or the electrochemical cell comprises a second contact element that connects a second cell terminal to a second connection conductor and that is fixed to the cover element by means of a second potting element in a second connection region, said second potting element being made of a second polymer material that comprises or is made of a second resin material.

A terminal film for a power storage device configured to cover an outer peripheral surface of a part of a metal terminal of the power storage device composed of a power storage device main body and the metal terminal electrically connected to the power storage device main body. The terminal film contains a hydrogen sulfide developer that changes color upon reacting with hydrogen sulfide. The hydrogen sulfide developer contains at least one element selected from the group consisting of, for example, copper, lead, silver, manganese, nickel, cobalt, tin and cadmium.
