Abstract
A nonaqueous secondary battery of the present invention comprises a polyvinylidene fluoride resin layer formed on either or both of the surface of the positive electrode and the negative electrode. This polyvinylidene fluoride resin layer exhibits excellent liquid retaining properties and thus can be formed on the surface of the electrodes to reduce the capacity drop during high temperature storage and hence improve the high temperature storage properties of the battery.
