Fully printed primary zinc-manganese dioxide (Zn|MnO 2 ) batteries in coplanar configuration were fabricated by sequential screen printing. While electrode dimensions and transferred active masses were kept at constant levels, electrode separating gaps were incrementally enlarged from 1 mm to 5 mm. Calendering of solely zinc anodes increased interparticle contact of active material within the electrodes while the porosity of manganese dioxide based electrodes was maintained by non-calendering. Chronopotentiometry revealed areal capacities for coplanar batteries up to 2.8 mAh cm −2 . Galvanostatic electrochemical impedance spectroscopy measurements and short circuit measurements were used to comprehensively characterise the effect of gap width extension on bulk electrolyte resistance and charge transfer resistance values. Linear relationships between nominal gap widths, short circuit currents and internal resistances were evidenced, but showed only minor impact ...

完全丝网印刷的共面Zn | MnO2电池的间隙宽度修改

通过顺序丝网印刷制造了共面配置的完全印刷的一次锌锰二氧化锰（Zn | MnO 2）电池。当电极尺寸和转移的活性物质保持恒定水平时，电极分离间隙从1 mm逐渐增加到5 mm。仅锌阳极的压延增加了电极内活性材料的颗粒间接触，同时通过非压延保持了基于二氧化锰的电极的孔隙率。计时电位法显示，共面电池的面积容量高达2.8 mAh cm -2。恒电流电化学阻抗谱测量和短路测量用于全面表征间隙宽度扩展对整体电解质电阻和电荷转移电阻值的影响。
