With the growing popularity of wearable electronics, flexible thin-film batteries have become a major focus for researchers. Innovations such as organic semiconductor thin-film transistors have emerged, but they face challenges like poor stability, making them unsuitable for real-world applications. According to a recent report from the Physicist Organization Network, a study published in *Applied Physics Letters* introduced a promising alternative: a zinc-manganese dioxide battery.
Many current studies aim to enhance the performance of organic semiconductor thin-film transistors. However, despite these efforts, the devices still suffer from limited flexibility, long molecular bonds, and thick dielectric layers—issues that prevent them from being used in practical scenarios. As a result, alkaline batteries like zinc dioxide have gained more attention due to their potential for better performance and easier integration.
One of the main reasons behind the development of thin-film printed batteries is their compatibility with existing manufacturing lines used for flexible electronic components. This allows for higher integration and reduced production costs. Compared to lithium-ion batteries, alkaline batteries are more eco-friendly, don’t require sealing, and are generally less expensive. By using stencil printing on fiber substrates, these batteries can be flexed and integrated into flexo-printed circuits, meeting the necessary performance requirements.
In the latest research, scientists developed a unique fabrication method that enabled them to connect 10 battery units in series, achieving a peak voltage of 14 volts and a capacity of 0.8 milliampere hours. The new thin-film battery uses commercially available materials like polyvinyl alcohol or polyvinyl cellulose films. A 100 μm thick film separates the zinc and manganese dioxide electrodes, acting as a substrate. A hydrophobic fluoropolymer solution (Teflon AF) was printed between the electrodes to minimize electrolyte migration and reduce unwanted contact between adjacent cells. Silver-containing ink was used to connect the different cells.
To test the battery’s performance, the researchers connected it to a 100 kΩ resistor. The 0.8 mAh battery discharged over 7.5 hours, with the voltage dropping from 14 volts to 10 volts. To evaluate its real-world applicability, they also tested it in a simulated environment. They built a simple circuit consisting of five inverters connected in sequence. The circuit's output was sensitive to the supply voltage and showed a measurable delay. The results showed that the voltage waveform remained around 13 volts during measurements taken every 10 milliseconds. After 20 minutes, no significant changes were observed, indicating that the battery provides a stable power supply.
The researchers noted that more complex circuits may require more energy, but this new zinc-manganese dioxide battery offers an additional viable option for printed batteries. This development could open new possibilities in the field of flexible electronics. (Wang Xiaolong)
