An electrode plate. Most of the area of the front thereof combines with a first electrode coating layer; most of the area of the back of the electrode plate combines with a second electrode coating layer; and a solid molecular polymer electrolyte coating layer respectively coats the first electrode coating layer and the second electrode coating layer. In this way, when an electrode plate serves as either of a positive electrode or a negative electrode, the positive electrode and the negative electrode are overlapped crosswise, the solid molecular polymer electrolyte coating layer being arranged between the positive electrode and the negative electrode; and when the positive and negative electrodes form a winding core in a manner of stacking or continuous winding, then a lithium battery core can be composed, making the battery core operate normally in an environment of high and low temperature, and stabilizing the performance of the battery, so as to ensure application safety. |
