    摘要： A method of producing an anode unit, whose active material consists of an alloy of an alkaline metal and a host metal therefore. An elongated element of the host metal is enclosed in a separator in form of a hollow fibre and is put in electrochemical contact with an organic solution of the alkaline metal, which migrates through the hollow fibre wall for alloying the host metal element. In a preferred embodiment strips are punched out at distances from each other in a sheet of the host metal and films of hollow fibre material, laid on the two surfaces of the sheet, are welded together in the openings left after the punching for forming hollow fibres.

    摘要： The invention relates to a method for operating a lithium-ion battery including at least one cell that includes: a negative electrode (14) (the first electrode) and a positive electrode (11) (the second electrode), between which a lithium-ion-conducting electrolyte is placed, and a third lithium-ion source electrode. Said method includes: a) a step for preparing said first electrode, said step including a lithiation operation, via the third electrode, of an electrode including a material made of at least one metal or semi-metal element M capable of forming an alloy with lithium such as to obtain said first electrode, including an active material that includes an alloy of at least one metal or semi-metal element M and lithium in a molar ratio Li/M up to 5, said step also being carried out under conditions sufficient to obtain said active material having a molar ratio Li/M (M being the metal or semi-metal element M as defined above) at least equal to 1/3 of the molar ratio when said material is completely alloyed with lithium; and b) a step of operation of said battery via cycling in lithium, between said negative electrode and said positive electrode, without totally delithiating said negative electrode, said step being carried out in a capacity domain corresponding to, at most, 2/3 of the total reversible capacity of the active material of said negative electrode.
