A metal battery (100), e.g. a lithium battery, comprising an anode (103); an anode current collector (101) in electrical contact with the anode; a cathode (109); a cathode current collector (109) in electrical contact with the cathode; a separator (107) disposed between the anode and cathode; a liquid electrolyte; and an anode protection structure comprising an anode protection layer (105) disposed between the anode and the separator. The anode protection layer has a matrix (105A) and domains (105B) within the matrix. One of the matrix and domains contains a first material and the other of the matrix and domains contains a second material. The first material is less permeable by the electrolyte than the second material. |
