As the world makes more use of renewable energy sources, new battery technology<\/a> is needed to store electricity for the times when the sun isn’t shining, and the wind isn’t blowing.<\/p>\n

“Current lithium batteries have reached their limitations in terms of energy storage capability, life cycle, and safety,” says Xiaolei Wang, a professor of chemical engineering at the University of Alberta in Edmonton. “They’re good for app<\/a>lications like electric vehicles and portable electronics, but they’re not suitable for large-scale grid-level energy storage.”<\/p>\n

With the help of the Canadian Light Source at the University of Saskatchewan, Wang and his team are developing new technologies to help make grid-level aqueous batteries that can use seawater as an electrolyte. The study is published<\/a> in the journal Advanced Materials<\/i>.<\/p>\n

Aqueous batteries can be safer, cheaper, and more environmentally friendly to make and dispose of than lithium-ion batteries, but their development has so far been limited by a lack of a good material to make a decent anode (the part of the battery where electricity flows out).<\/p>\n

Wang’s team developed a material made of polymer nanosheets and carbon nanotubes that is suitable for storing a variety of different types of ions, including those found naturally in seawater. These anodes are thicker than previous ones, so have a high capacity for storing energy, and are extremely durable so they can last a long time\u2014up to 380,000 charging cycles in some cases\u2014and they can operate under extreme conditions such as fast charging and discharging, or at low temperatures, says Wang.<\/p>\n
