Researchers Develop Stretchable, Sustainable Fluid Battery

Linköping University unveils a groundbreaking battery design using liquid electrodes, achieving flexibility and sustainability, though voltage limitations remain a challenge.

The new fluid battery, developed by Linköping University, replaces solid electrodes with liquid ones, allowing it to take any shape and integrate seamlessly into various technologies.
Made from conductive plastics and lignin, the battery offers an eco-friendly alternative by utilizing abundant and sustainable materials, including a byproduct of paper production.
The battery maintains performance over 500 charge cycles and can stretch to twice its original length without losing functionality, demonstrating durability and adaptability.
Current limitations include a low voltage of 0.9 volts, with ongoing research exploring zinc and manganese compounds to enhance its performance.
This innovation addresses the growing demand for flexible power solutions as over a trillion connected devices, including wearables and medical implants, are expected in the near future.
