Fig. 1 and 2 display is according to the cross section of the electrode for secondary battery of the sheet form of the utility model execution mode, and Fig. 3 schematically shows the method for optimizing of preparation according to the electrode for secondary battery of the sheet form of the utility model execution mode.
With reference to figure 1-3, the electrode for secondary battery according to of the present utility model form comprises: current-collector 10; Be formed in the electrode active material layers 20 on a surface of described current-collector 10; To be formed in described electrode active material layers 20 and to comprise the porous organic and inorganic layer 30 of inorganic particulate and polymer adhesive; Be formed in the first porous support layer 40 on porous organic and inorganic layer 30.
Further, the second supporting layer 50 be formed on described another surface of current-collector 10 can be comprised according to the electrode for secondary battery of the sheet form of the utility model execution mode.
In order to make battery have flexibility, enough flexibilities should be had for the electrode in battery.But, when the regular cable type battery as a flexible battery example, electrode active material layers is easy to the stress because causing for the external force of change of shape or its fast volume when using the high power capacity negative active core-shell material containing Si, Sn etc. during charging and discharging process expands and comes off.This capacity deteriorated cycle life characteristics that reduce battery of coming off of electrode active material layers.As the trial overcoming this problem, improve the amount of adhesive in electrode active material layers to bend or to provide flexible during distortion.
But the amount of binder improved in electrode active material layers causes electrode resistance to raise and deterioration.In addition, when applying strong external force, such as, when being folded completely by electrode, even if the quantitative change of adhesive is large, still can not prevent electrode active material layers from coming off.Therefore, the method is not enough to address this is that.
