Abstract
In an electrochemical cell having an active metal negative electrode, a positive electrode and a electrolyte separator there is provided a first layer between the negative electrode and the electrolyte separator, the layer comprises a carbon-based material which is a conductor of electrons and a conductor of metal ions of the negative electrode. The layer restricts penetration of electrolytic organic and anionic salt constituents therethrough and prevents degradation of the negative electrode.
