The world continues to become increasingly interconnected, and as such, the demand for flexible technologies that can power a variety of devices is on the rise. The concept of flexible batteries, which can stretch to fit different form factors, has long been the holy grail of electronics manufacturing.
Scientists from Linköping University in Sweden have made significant strides in this area, developing a flexible battery that can stretch twice its length and maintain its performance.
The battery in question utilizes liquid electrodes, conductive plastics, and lignin, a byproduct of paper production.
The material used in the battery is comprised of conjugated polymers and lignin, which are abundant and sustainable.
The benefits of this new battery are numerous, including the fact that it can be recharged and discharged over 500 times without losing performance.
Moreover, the battery is environmentally conscious, as it does not rely on rare earth materials.
The researchers have also highlighted the potential for this technology to be used in various applications, such as wearable technologies, insulin pumps, hearing aids, pacemakers, and the development of fast robotics.
Limitations of Traditional Batteries
Traditional batteries have several limitations, including their inflexibility and rigidity.
In fact, flexing a lithium-ion battery too far can be a serious safety risk, as it can lead to a flammable disaster.
However, the new flexible battery developed by the scientists at Linköping University addresses this issue, as it can stretch to double its length without compromising its performance.
The researchers have also demonstrated that the battery can be recharged and discharged over 500 times without losing performance.
Sustainable Materials and Design
The researchers used a material made from conductive plastics and lignin in their battery design.
Lignin, a byproduct of paper production, is abundant and sustainable.
The use of this material in the battery design reduces the reliance on rare earth materials and contributes to a more circular model.
Future Research Directions
The researchers are currently exploring ways to increase the voltage of the battery to compete with lithium-ion batteries.
They are considering chemical compounds using zinc or manganese, two of the most abundant metals found on Earth.
The goal is to develop a battery that can match the voltage of a typical smartphone, which can tick upwards of four volts.
The scientists are also committed to maintaining the battery’s sustainable bonafides, and are exploring ways to incorporate more environmentally friendly materials into the design.
Conclusion
The development of flexible batteries is a significant step forward in the field of electronics manufacturing.
The new battery developed by the scientists at Linköping University has the potential to revolutionize the way we design and manufacture electronic devices.
With its ability to stretch to double its length and maintain performance, the battery is an attractive option for a variety of applications.
As researchers continue to explore new materials and design approaches, the future of flexible batteries looks bright.

“The texture is a bit like toothpaste,” said Aiman Rahmanudin, a co-author of the study. “The material can, for instance, be used in a 3D printer to shape the battery as you please. This opens up for a new type of technology.”
“Since the materials in the battery are conjugated polymers and lignin, the raw materials are abundant,” said Mohsen Mohammadi, a postdoctoral fellow and co-author of the study. “By repurposing a byproduct like lignin into a high value commodity such as a battery material we contribute to a more circular model. So, it’s a sustainable alternative.”
Flexible? Check. Sustainable? Also check. So, what’s the catch? Well, right now, the voltages in the battery can’t quite compete with lithium-ion batteries.
