Salt, ice, and a little bit of oomph – these are the ingredients that researchers have discovered can generate waste-free electricity. The study, published in Nature Materials, highlights the flexoelectric effect, where electricity is produced through the irregular deformation of a solid material. While most materials have weak flexoelectricity, salted ice shows promise as a renewable energy source.
The research team, led by experimental physicist Xin Wen, found that impurities in ice, such as salt, play a crucial role in generating electricity. Pure ice was previously shown to be flexoelectric, shedding light on the mechanism behind lightning in thunderstorms. By freezing saltwater in various shapes and bending the briny ice, the researchers were able to measure the electrical charge produced. They found that cone-shaped ice structures were more efficient in generating voltage compared to curved beams.
The key to this phenomenon lies in the thin layers of liquid brine within the solid ice, which contain positively charged particles called cations. When the ice is bent, a pressure gradient is created, causing the brine to flow towards areas of lower pressure. This movement of salty liquid generates an electric current, resulting in the production of electricity.
While the idea of using saline ice for energy-harvesting devices or sensors in cold environments is promising, there is still a long way to go before it can power everyday devices. According to Wen, a large cube of salty ice would be needed to charge a smartphone at this stage. However, further research and development could potentially reduce the size and increase the efficiency of salted ice as a renewable energy source.
Overall, the study showcases the potential of salted ice as a sustainable and eco-friendly way to generate electricity. With continued research and innovation, salted ice could pave the way for new energy harvesting technologies that benefit both the environment and society.
