<p>A negative electrode material which has as a main component hardly graphitized carbon containing carbon, phosphorus and oxygen as main components, or coke (easily graphitized carbon), and includes 0.2-9.0 weight % phosphorus. The negative electrode material has peaks at +/- 100 ppm relative to orthophosphoric acid as the reference in the <3><1>P nuclear solid NMR spectrum, and has a peak of 135.0 eV in the 2p orbital spectrum of phosphorus atom in the XPS. The negative electrode material is manufactured by adding phosphoric acid, phsphorus oxide, etc., to an organic material or a carbon material, and by burning the mixture. A nonaqueous electrolyte battery is made from the negative electrode material, a positive electrode including Li, and an electrolyte. <IMAGE></p> |
