The present invention relates to a positive electrode activenmaterial, a negative electrode active material and an electrolyte thatnare used alone or in combination to improve charge and discharge cyclencharacteristic, low temperature characteristic and safety of annon-aqueous electrolyic secondary battery, particularly a lithium ionnsecondary battery. Specifically, a particulate Li-transition metalncomposite oxide having an average particle size of not less than 10nµm, wherein [20/(specific surface area×average particle size)]=7-n9 , is used as a positive electrode active material. |
