摘要： Disclosed is a battery with a light weight and a high energy density. The battery includes a anode 5, having a layer of an anode active material 9 formed on an anode substrate 8, a cathode 6, including a layer of a cathode active material 14 formed on a cathode substrate 13, and a non-aqueous liquid electrolyte 4. The anode substrate 8 includes an anode resin film 11 containing a polymer and an anode metal layer 12 containing an electrically conductive metal. Since the anode resin film 11 reduces the weight of the anode substrate 8 and the anode metal layer 12 imparts electron conductivity to the anode substrate 8, the battery may be reduced in weight without detracting from battery characteristics to increase the energy density.

摘要： A negative electrode of a nonaqueous secondary battery is formed of a carbonaceous material. The ratio RG=Gs/Gb of the degree of graphitization Gs of the carbonaceous material, determined by a surface-enhanced Raman spectrum, to the degree of graphitization Gb, determined by a Raman spectrum measured using argon laser light, is at least 4.5. Alternatively, the carbonaceous material has a peak in a wavelength range above 1,360 cm−1 in a surface-enhanced Raman spectrum which is measured by the same surface-enhanced Raman spectrum. The deterioration of the nonaqueous secondary battery is suppressed during use in high-temperature environments and high capacity is maintained for long periods.

摘要： An anode material composed mainly of a difficultly graphatizable carbon or coke (easily graphatizable coke) consisting essentially of carbon, phosphorus and oxygen, and containing phosphorus in an amount of 0.2 to 9.0 wt %, is disclosed. The anode material exhibits a peak in a .sup.31 P solid NMR spectrum in a range of .+-.100 ppm based on orthophosphoric acid, and a peak in a 2p orbital spectrum of a phosphorus atom in XPS of not more than 135 eV. The anode material is prepared by adding phosphoric acid or phosphorus oxides to an organic material or a carbonic material. A non-aqueous liquid electrolyte cell is produced from the above anode material, an Li-containing cathode and a liquid electrolyte.
