An electrode plate comprising a current collector (10), a layer of active material on the electrodes (14) and a safety coating (12) disposed between the current collector (10) and the layer of active material on the electrodes (14), where the safety coating (12) comprises a polymer matrix, a conductive material and an inorganic charge, where the amount of other components is less than or equal to 3% by weight and where the matrix of polymer is a polymer matrix of fluorinated polyolefin and / or chlorinated polyolefin, in which based on the total weight of the security coating (12), the percentage by weight of the polymeric matrix is 35% by weight to 75% in weight; the percentage by weight of the inorganic filler is from 10% by weight to 60% by weight. |
