摘要：A negative electrode material which has as a main component hardly

graphitized carbon containing carbon, phosphorus and oxygen as main components, orcoke (easily graphitized carbon), and includes 0.2-9.0 weight % phosphorus. The negativeelectrode material has peaks at ± 100 ppm relative to orthophosphoric acid as thereference in the ³¹P nuclear solid NMR spectrum, and has a peak of 135.0 eV in the 2porbital spectrum of phosphorus atom in the XPS. The negative electrode material ismanufactured by adding phosphoric acid, phsphorus oxide, etc., to an organic material ora carbon material, and by burning the mixture. A nonaqueous electrolyte battery is madefrom the negative electrode material, a positive electrode including Li, and an electrolyte.
