s: The manufacturing of porous lithium aluminium alloy anode containing cerium was investigated. The effects of cerium on the mechanical and physical properties of lithium aluminium alloy anode were discussed and the charging discharging behavior of the electrode was also tested. It is shown that the ideal porous aluminium can be obtained by pressing at 100～150 MPa and sintering at 550～570℃ by using NaCl as porous packing. The porous β lithium aluminium alloy anode containing 0 5%～1 5% cerium was obtained by electrodepositing cerium and lithium on the porous aluminium respectively and it has the best charging discharging properties.
