Pole plate structure

The utility model relates to a polar plate structure, comprising a collector body, an active layer and a safety protective layer. The collector includes Al, Cu or stainless steel. The active layer is adjacent to the collector and includes graphite, silicon, carbon, or combinations of the above. The protective coating covers all the upper and lateral surfaces of the active layer and contains an oxide of the general formula of MxOy. Among them, M is Si, Al, Zr, Ti, Mg, Zn, Li, La, Nb, Ta, Ge, B, Y, Se, or the combination of the above. X is between 1-2. Y is between 1-3. 种极板结构，其包括集电体、活性层与安全防护层。集电体包括Al、Cu或不锈钢。活性层邻接在集电体上，并包括石墨、硅碳或上述的组合。安全防护层包覆活性层的所有上表面及侧表面，并包含通式为MO的氧化物。其中M为Si、Al、Zr、Ti、Mg、Zn、Li、La、Nb、Ta、Ge、Y、Se、B或上述的组合。x介于1～2。y介于1～3。
