Paper electronics offer an environmentally sustainable option for flexible and wearable systems and perfectly fit the available printing technologies for high manufacturing efficiency. As the heart of energy-consuming devices, paper-based batteries are required to be compatible with printing processes with high fidelity. Herein, hydrogel reinforced cellulose paper (HCP) is designed to serve as the separator and solid electrolyte for paper batteries. The HCP can sustain higher strain than pristine papers and are biodegradable in natural environment within four weeks. Zinc-metal (Ni and Mn) batteries printed on the HCP present remarkable volumetric energy density of ≈26 mWh cm^–3, and also demonstrate the feature of cuttability and compatibility with flexible circuits and devices. As a result, self-powered electronic system could be constructed by integrating printed paper batteries with solar cells and light-emitting diodes. The result highlights the feasibility of hydrogel reinforced paper for ubiquitous flexible and eco-friendly electronics.

印刷锌纸电池

纸电子产品为柔性和可穿戴系统提供了一种环境可持续的选择，并完美地适合现有的印刷技术，以实现高制造效率。作为耗能设备的核心，纸基电池需要高保真度地兼容印刷工艺。在此，水凝胶增强纤维素纸（HCP）被设计用作纸电池的隔膜和固体电解质。HCP 可以承受比原始纸张更高的压力，并且在自然环境中可在 4 周内生物降解。在HCP上印刷的锌金属（镍和锰）电池具有约26 mWh cm ^–3的出色体积能量密度，并且还表现出可切割性以及与柔性电路和设备的兼容性的特征。因此，可以通过将印刷纸电池与太阳能电池和发光二极管集成来构建自供电电子系统。结果凸显了水凝胶增强纸用于无处不在的柔性和环保电子产品的可行性。
