Abstract
A lithium-ion storage battery includes LiFePO4 as an active material for a positive electrode, an active material for a negative electrode having a lithium insertion/extraction potential equal to or greater than 0.5 V vs. Li+/Li, and a separating element placed between the positive and negative electrodes. The active material for the negative electrode is a lithiated titanium oxide, a derivative of a lithiated titanium oxide, a non lithiated titanium oxide, a derivative of a non lithiated titanium oxide or a mixture thereof. The separating element is formed from a non-woven fabric comprising cellulose fibers or glass fibers of nanometric and/or micrometric size.
