Researchers develop metal-free water-based battery that can effectively reduce battery flammability -Lithium - Ion Battery Equipment

Batteries play an important role in modern life, powering laptops, phones, robot vacuum cleaners, hearing aids, pacemakers, and even electric cars. But at the same time, it also presents safety risks and impacts on the environment. Texas A&M University (Texas A&M University) conducted research on the composition of a special battery-metal-free water-based battery. The battery reduces the flammability of standard batteries and uses fewer metals in the battery production process.

Most batteries today are lithium-ion batteries containing lithium and cobalt, which are strategic global resources that only exist in certain countries but are important to the global economy and the U.S. battery manufacturing industry.

Dr. Jodie Lutkenhaus, Artie McFerrin Professor of Chemical Engineering at Texas A&M University and Chairman of Axalta Coating Systems, said: "This work opens up the possibility of designing metal-free aqueous batteries. By being metal-free, we can meet the global demand for batteries. There is an urgent need for strategic metals, and by using water-based materials, we can replace flammable volatile electrolytes with water."

By using a more sensitive measurement technique, an electrochemical quartz crystal microbalance with dissipation monitoring, the researchers were able to determine how electrons, ions and water are transferred in the electrode as it charges and discharges.

"By understanding this information, we demonstrate that enhanced interuse of electrodes and water can improve energy storage performance," Lutkenhaus said. Although the energy storage capacity of the battery is lower than that of traditional lithium-ion batteries, it also provides the opportunity for a more sustainable and more sustainable future. Non-volatile batteries pave the way. This research is currently in its early stages and has many practical application opportunities, including implantable batteries for medical devices.(Lithium - Ion Battery Equipment)

"By using completely different materials, such as the polymers we used, it is possible to completely remove the metal from lithium-ion batteries," Lutkenhaus said. "What I liked most about this work was being able to deeply characterize the interactions with this redox polymer. Molecular transport process. And it is only in the past few years that we have been able to achieve this goal in time and scale." Lutkenhaus said that in the future they will find more polymers that are compatible with the design. She added: "Once found, we can produce a high-performance full battery cell that can be used in practical applications."
