Dataset for "Water activated disposable paper battery"

We developed a disposable paper battery aiming to reduce the environmental impact of single-use electronics for applications such as point of care diagnosis, smart packaging and environmental sensing. The battery uses Zinc as a biodegradable metal anode, graphite as a nontoxic cathode material and paper as a biodegradable substrate. To facilitate additive manufacturing, we developed electrodes and current collector inks that can be stencil printed on paper to create water-activated batteries of arbitrary shape and size. The battery remains inactive until water is provided and absorbed by the paper substrate, taking advantage of its natural wicking behavior. Once activated, a single cell provides an open circuit potential of 1.2 V and a peak power density of 150 µW/cm2 at 0.5 mA. As a proof of concept, we fabricated a two cell battery and used it to power an alarm clock and its liquid crystal display.

本研究开发了一款一次性纸基电池，旨在降低一次性电子产品对环境的负面影响，可应用于床旁诊断（point of care diagnosis）、智能包装与环境传感等场景。该电池以锌作为可降解金属阳极，石墨作为无毒阴极材料，纸张作为可降解基底。为适配增材制造需求，本研究开发了电极与集流体油墨，可通过丝网印刷工艺将其印刷于纸张之上，从而制得任意形状与尺寸的水激活电池。该电池在纸张基底吸收水分激活前始终处于休眠状态，这一设计利用了纸张天然的芯吸效应。激活后，单节电池可提供1.2 V的开路电位，并在0.5 mA电流下实现150 µW/cm²的峰值功率密度。作为概念验证，本研究制备了两节电池构成的电池组，并利用其为一台闹钟及其液晶显示屏（liquid crystal display）供电。
