ABSTRACT:
A lithium storage cell comprises at least a first electrode comprising an active material wherein Li+cations can be inserted, a second electrode and an electrolyte. The active material of the first electrode comprises a linear condensed compound comprising at least two tetrahedra, respectively of AO4and A′O4type, bonded by a common oxygen atom. A transition metal ion M2+with a degree of oxidation of +2 selected from the group consisting of Ni2+, Co2+, Mn2+, Fe2+and Ti2+is inserted in the linear condensed compound, and the ratio between the number of Li+cations able to be inserted in the active material and the number of transition metal ions M2+is strictly greater than 1. A and A′ are selected from the group consisting of P5+, Si4+, Al3+, S6+, Ge4+, B3+.
