Abstract (en)
[origin: WO2015121574A1] The subject of the invention is a lithium-ion battery comprising a graphite-based material for negative electrode, a lithium-rich material for positive electrode, an electrolyte and a separator, characterized in that the reversible capacity (N) of said negative electrode is equal to the reversible capacity (P) of said positive electrode so that said battery exhibits a ratio N/P = 1. The subject of the invention is also a method of preparing Li‑ion batteries according to the invention. Finally, the subject of the invention is a method of cycling a lithium-ion battery according to the invention.
