Lithium storage cell capable of operating at high temperature

摘要

The use of a rechargeable lithium storage cell at a temperature lying in the range 80° C. to 180° C., said cell comprising a cathode, an anode comprising either Li₄Ti₅O₁₂ or a carbon-containing material capable of inserting lithium, a separator, a non-aqueous solvent, and a lithium slat, wherein: the active material of said cathode is a lithiated metal oxide having the following formula: LiNi_1-x-yCo_xAl/Mn_yO₂ in which: Al/Mn means Al and/or Mn; 0<=x<=0.5; 0<=y<=0.5; the sum x+y being less than 0.66; and wherein the lithium salt is selected from the group consisting of: LiPF₆, LiBF₄, LiBOB, LiBETI, and mixtures thereof.
