Small form factor battery with high power density

A base cell structure includes a containment ring defining an opening extending therethrough. An inner wall of the containment ring defines a peripheral boundary of the base unit volume. The containment ring provides a liquid impermeable enclosure at a peripheral boundary. A first set of active particles is disposed in the elementary cell volumes of the first elementary cell structure to form an anode cell. A second set of active particles is disposed in the elementary cell volumes of the second elementary cell structure to form a cathode cell. The anode unit and the cathode unit are assembled together with a separator disposed between the anode unit and the cathode unit. Two electrode plates are disposed on the assembly, one adjacent to the anode unit and one adjacent to the cathode unit to provide an anode electrode plate and a cathode electrode plate, respectively, disposed on opposite outer sides of the assembly. 一种基本单元结构包括界定延伸穿过其的开口的容纳环。容纳环的内壁界定基本单元容积体的周边界限。容纳环在周边界限处提供液体不可渗透的外壳。第一组活性颗粒被设置在第一基本单元结构的基本单元容积
