NOVELTY - The electrode has a negative electrode mixture (102) including a binder and an active material particle e.g. carbonaceous material particle, metal particle and metal oxide particle, formed on a current collector (101), where ratio between a cutting strength of an interface between the current collector and the electrode mixture and cutting strength in a horizontal direction within the electrode mixture is greater than 1. A separator is housed in an exterior unit. The exterior unit is filled with a non-aqueous electrolyte.    USE - Electrode e.g. positive electrode and negative electrode, for a non-aqueous electrolytic battery and a non-aqueous electrolytic secondary battery in a battery pack (all claimed), utilized in a mobile electronic equipment e.g. smart phone and digital camera, in a hybrid electric automobile, an electric automobile and an assist automobile.    ADVANTAGE - The negative electrode mixture includes the binder and the active material particle formed on the current collector, so that size of silicon oxide phase is made small and uniform to hinder growth of crystallite size of microcrystal silicon, thus suppressing capacity deterioration due to charge and discharge cycle and improving life characteristic of the electrode. The electrode allows a porous film to be made of polyethylene or polypropylene, thus improving safety of the secondary battery. The electrode reduces expansion and shrinkage of the silicon phase due to insertion and desorption of large amount of lithium by dispersing the silicon phase in the silicon oxide phase and the carbonaceous material to prevent pulverization of the active material particle, while a carbonaceous material phase ensures conductivity, which is important as the negative electrode active material and the silicon oxide phase is strongly bound with silicon and has a large effect on maintenance of a particle structure as a buffer for retaining silicon is made fine.    DETAILED DESCRIPTION - The electrode is a negative electrode (100). An INDEPENDENT CLAIM is also included for a non-aqueous electrolytic secondary battery.
