Document Type and Number:
Japanese Patent JPH09265986
Kind Code:
A
Abstract:
To provide the non-aqueous electrolyte secondary battery (lithium secondary battery) high in discharging capacity.
Graphite is used as a negative electrode, in which the spacing (d002) of its surface based on a X-ray wide angle diffraction method (002) is less than 0.336nm, and a correlative length (Ic) obtained by a X-ray small angle scattering method, is equal to or more than 12nm. The aforesaid graphite can be obtained by crushing natural graphite by a jet crusher using discharge pressure equal to or more than 5kgf/cm2.
