  "textContent": "The present invention relates to a rechargeable lithium generator comprising a positive electrode whose electrochemically active material comprises at least one oxide of a transition metal, and a negative electrode comprising a conductive support and an active layer containing an electrochemically active material which is a mixed oxide of lithium and titanium of general formula LixTiyO4 in which 0.8 ≤ x ≤ 1.4 and 1.6 ≤ y ≤ 2.2, and a binder which is a polymer containing no fluorine. The non-fluorinated polymer is preferably soluble in water or capable of forming a stable emulsion when suspended in water. The binder preferably contains an elastomer, in particular an acrylonitrile and butadiene copolymer or a styrene and butadiene copolymer, and/or a cellulosic compound such as carboxymethylcellulose.",
