    摘要： The invention discloses a lithium battery structure and the electrode layer thereof. The lithium battery structure includes two battery units with the two negative active material layers being disposed in face-to-face arrangement. The negative current collector includes a conductive substrate with a plurality of through holes and an isolation layer. The isolation layer is covered on one surface of the conductive substrate and extended along the through holes to another surface to cover the edge of the openings of the through holes. It can be effectively avoided the lithium dendrites depositing near the openings of the through holes on the conductive substrate. Also, the face-to-face arrangement of the negative active material layers is effectively control the locations of the plated lithium dendrites. Therefore, the safety of the battery and the cycle life of the battery is greatly improved.

    摘要： The current thickness limitations of battery electrodes are addressed. An electrode includes an electrically conductive porous foam layer, an energy-storage material in contact with the porous foam layer, and electrically conductive porous foam protrusions extending from the porous foam layer into the energy-storage material. The energy-storage material is not contained within the pores of the foam layer or the foam protrusions. These electrodes allow lithium ions (and other metal ions, if desired) to diffuse deeper into a thick energy-storage material layer, compared to conventional planar electrodes. In particular methods, fluidic foam precursors can be templated in a mold, followed by conversion into a solid conductive foam that includes the electrically conductive porous foam protrusions. The result is batteries with surprisingly high energy densities.

    摘要翻译： 解决了电池电极的当前厚度限制。 电极包括导电多孔泡沫层，与多孔泡沫层接触的能量存储材料，以及从多孔泡沫层延伸到储能材料中的导电多孔泡沫突起。 能量储存材料不包含在泡沫层或泡沫突起的孔内。 与常规平面电极相比，这些电极允许锂离子（和其它金属离子，如果需要）扩散到较厚的储能材料层。 在具体的方法中，流体泡沫前体可以在模具中模板化，随后转变成包括导电多孔泡沫突起物的固体导电泡沫体。 结果是具有令人惊讶的高能量密度的电池。
