More Information
Summary:A nonaqueous electrolytic secondary battery comprising an anode consisting of a carbon material, an electrolyte containing a lithium salt, and a cathode consisting of a material capable of occluding/releasing lithium metal or lithium, characterized in that the anode consists of a graphite boride material, and an abundance ratio of boron and boron compound in terms of boron is 0.05-11 wt.%; and a method of producing the anode material thereof. L'invention concerne une batterie électrolytique secondaire non aqueuse comprenant une anode constituée d'un matériau de carbone, un électrolyte contenant un sel de lithium et une cathode constituée d'un matériau pouvant renfermer/libérer du lithium-métal ou du lithium. Cette batterie secondaire se caractérise en ce que l'anode est constituée d'un matériau de borure de graphite et que le rapport des teneurs de bore et de composé de bore, pour ce qui est du bore, est compris entre 0,05 et 11 % en poids. L'invention concerne également un procédé de production dudit matériau d'anode.
