Researchers Achieve Breakthrough in Flexible and Sustainable Battery Technology

Linköping University develops a fluid, stretchable battery with liquid electrodes, while UC Berkeley pioneers a durable, jelly-like lithium-ion alternative.

Scientists at Linköping University have created a flexible battery using liquid electrodes, capable of stretching to twice its length while maintaining performance across 500 recharge cycles.
The battery incorporates sustainable materials, including conductive plastics and lignin, a byproduct of paper production, promoting environmentally friendly design.
Despite its flexibility and sustainability, the battery currently operates at a low voltage of 0.9 volts, with ongoing research aimed at increasing its output using alternative chemical compounds.
UC Berkeley researchers have developed a complementary jelly-like lithium-ion battery using hydrogel electrolytes, which withstands bending, twisting, and cutting without compromising safety.
These advancements address long-standing limitations of rigid battery designs, paving the way for applications in wearables, medical implants, and soft robotics.
