Argonne National Lab issues lithium-sulfur battery research update

By On Jan 9, 2023

Although lithium-ion batteries are the mainstay of electric vehicles today, they have certain drawbacks. They tend to overheat and don’t always last as long as we would like. Also, some of the raw materials are in short supply, which means the cost to manufacture them is going up instead of down as expected due to economies of scale.

Scientists at the US Department of Energy’s Argonne National Laboratory are investigating solutions to these problems by testing new materials in battery construction. One such material is sulfur, which is abundant and profitable. It can also store much more energy than traditional lithium-ion batteries. The researchers claim that 2600 Wh per kilogram is possible.

In a recent study published in the journal Nature Communications, researchers reported advances in sulfur-based battery research achieved by creating a layer inside the battery that adds energy storage capacity while nearly eliminates a traditional problem with sulfur batteries that caused corrosion. “These results demonstrate that a redox-interactive layer could have a great impact on Li-S battery development. We are one step closer to seeing this technology in our daily lives,” says Wenqian Xu, who is a member of the ‘research team.

The promising new battery design combines a sulfur-infused positive electrode with a lithium metal negative electrode. Among these components is the electrolyte, the substance that allows ions to pass between the two ends of the battery. Early lithium-sulfur batteries did not perform well because the polysulfides dissolved in the electrolyte, causing corrosion. This effect of polysulfide transport negatively affects battery life and reduces the number of times it can be recharged.

To prevent this transfer of polysulfide, the researchers attempted to place a redox-inactive intermediate layer between the cathode and anode. The term “redox-inactive” means that the material does not undergo reactions like those of an electrode. But this protective interlayer is heavy and dense, reducing the energy storage capacity per unit weight of the battery. It also does not adequately reduce transportation, which has proven to be a major barrier to the commercialization of lithium-sulfur batteries.

To address this, the researchers developed and tested a sulfur-infused porous interlayer. Tests in the laboratory showed an initial capacity of approximately three times greater in lithium-sulfur cells with this active interlayer, as opposed to the inactive one. The cells with the active interlayer maintained a high capacity for 700 charge/discharge cycles.

“Previous experiments with cells that had the redox-inactive layer only suppressed transport, but in doing so, they sacrificed energy for a given cell weight because the layer added extra weight,” he says. Guiliang Xu, an Argonne chemist and co-author of the paper. “In contrast, our active redox layer increases energy storage capacity and suppresses the shuttle effect.”

To further study the redox-active layer, the team conducted experiments at the Argonne Advanced Photon Source, a DOE Office of Science user facility. Data collected from exposing cells with this layer to X-ray beams allowed the team to determine the benefits of the interlayer.

The data confirmed that a redox-interactive layer can reduce transport, reduce harmful reactions within the battery, and increase the battery’s ability to hold more charge and last longer cycles. “These results show that a redox-interactive layer could have a great impact on Li-S battery development,” says Wenqian Xu, “We are one step closer to seeing this technology in our daily lives.” Looking ahead, the team wants to assess the growth potential of redox-active interlayer technology. “We want to try to make it much thinner, much lighter,” says Guiliang Xu,

In summary, the researchers write: “We propose a polar, redox-active interlayer concept for high-energy, long-cycle Li-S batteries, in which sulfur is embedded in ordered mesoporous silica of polar platelets to form a interlayer Interestingly, sulfur storage/trapping occurs in polar silica while electron transfer to the conducting agent in pOMS/Sx IL during charge discharge.

“During the electrochemical processes, this interlayer not only fulfills the function of effectively preventing the transport of long-chain polysulfides, but also contributes to the improvement of the cell capacity. The cell with an optimal interlayer offers an areal capacity of >10 mAh cm−2 with the advantage of a high sulfur loading of >10 mg cm−2 and stable cyclability for 700 cycles, even with a high specific current cycle and a low electrolyte/sulfur ratio. These attributes can increase the practical specific energy of Li-S batteries.”

Lithium-Sulfur Research Around The World

Many battery researchers are exploring the feasibility of sulfur batteries, primarily because sulfur is one of the most abundant and readily available materials on Earth. While lithium-ion batteries have worked incredibly well to start the electric vehicle revolution, they are only a precursor to the batteries that await us in the coming years.

Researchers in Australia are exploring batteries that combine sulfur with sodium. Theionm, a German battery company, is also researching lithium-sulphur amid claims that such batteries could triple the range of electric vehicles. A year ago, we reported on research conducted at the University of Michigan on lithium-sulfur batteries that are said to last up to 1000 charge/discharge cycles.

The problem, as always, is getting advanced battery technology out of the lab and into commercial production. It was five years ago that we reported on research at MIT that held promise for lithium-sulfur batteries for grid-scale storage applications. To our knowledge, no commercial application of this research has yet occurred. The fascinating part of the MIT studies was the claim that these batteries would cost only 1% of conventional lithium-ion batteries. Imagine how this would disrupt the utility industry!
