Researchers in the United States have achieved a significant breakthrough in the development of solid-state, anode-free sodium batteries. This promising advancement not only offers enhanced levels of safety but also tackles the high costs associated with traditional batteries.
The team of scientists, led by Grayson Deysher, a PhD candidate at the University of California – San Diego, has successfully combined three essential ideas – sodium-based technology, solid-state electrolytes, and anode-free designs – in a pioneering battery. Their groundbreaking achievement has been published in the esteemed journal Nature Energy.
One of the key advantages of this solid-state sodium battery is its impressive durability. It can undergo charging and discharging cycles for up to 400 times without any noticeable degradation. The research team, led by Professor Ying Shirley Meng from the University of Chicago, has filed a patent application for this innovative technology.
Conventional batteries consist of an anode, which supplies electrons, and a cathode, which accepts them. The flow of electrons from the anode to the cathode produces electrical energy. Additionally, batteries require current collectors to connect the anode and cathode with outer circuits, as well as electrolytes to facilitate the movement of charged particles within the battery.
While it is possible to create batteries without anodes, storing the charged particles directly on a current collector, this technique has proven challenging to implement effectively. In an anode-free battery, establishing good contact between the electrolyte and the current collector is crucial. However, this is relatively straightforward with liquid electrolytes, as they can flow and cover every surface. Solid electrolytes, on the other hand, do not possess this capability.
To overcome this challenge, the research team adopted an innovative approach. They used aluminum powder as a current collector, allowing it to flow freely around the solid electrolyte during the battery assembly process. This resulted in the creation of a stable, solid-state sodium battery without the need for an anode.
Deysher believes that this breakthrough has the potential to invigorate the development of sodium-based batteries, debunking the notion that they are a distant future technology. In fact, he suggests that in certain cases, solid-state sodium batteries might perform even better than their lithium counterparts. This discovery opens new horizons for the energy storage industry, offering a more affordable and safer alternative to current battery technologies.
