    摘要: 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 AO4 and A′O4 type, 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+.
