YTU scientists develop hybrid polymer to extend battery life
Assoc. Prof. Dr. Ali Can Zaman of YTU's Metallurgy Department and his team have developed a hybrid polymer by reacting acetone with sulfur, which could extend battery life and enable fast charging.
Assoc. Prof. Dr. Ali Can Zaman, a faculty member of Yıldız Technical University's (YTU) Metallurgy Department, and his team have achieved a breakthrough that could revolutionize battery technology. The team developed a new polymer with hybrid properties by reacting acetone with elemental sulfur using a unique polymerization method.
The developed material can be used as a cathode material in lithium-sulfur batteries thanks to its energy storage capability. This aims to extend battery life and enable faster charging and discharging.
"We obtained a polymer with hybrid properties"
Assoc. Prof. Dr. Ali Can Zaman told an AA reporter that their ultimate goal is to develop a technology that extends battery life and enables faster charging.
Noting that elemental sulfur used in lithium-sulfur batteries is a cheap and abundant material, Zaman stated that its hydrophobic nature makes it difficult to use directly in developing long-life batteries. Zaman said they developed a new polymerization technique to overcome this disadvantage, and added:
With this method, we obtained polymeric materials by reacting elemental sulfur with organic compounds that would not normally be expected to react. We realized that we can suppress some of the negative properties of sulfur. The new material we obtained carries some properties of sulfur while also incorporating properties from the organic compounds. In fact, we obtained a polymer with hybrid properties. Acetone is a simple, widely known organic compound. Thanks to the method we developed, we reacted acetone with elemental sulfur to obtain a new polymer material. The resulting materials exhibit electroactive properties, allowing them to store energy. The results could pave the way for the development of longer-lasting batteries that charge and discharge faster after sufficient optimization studies.
Zaman emphasized that although similar studies have been conducted before, obtaining a new class of material by reacting a simple molecule like acetone with elemental sulfur using this method is a novel approach in the literature.
Could also be used in water treatment and carbon dioxide capture
Assoc. Prof. Dr. Zaman stated that the developed material is not limited to batteries, saying, "Derivatives of these materials can also be used in carbon dioxide capture applications. We carried out these applications and achieved good performance. Thus, we have proven that it can be used in both energy storage and carbon dioxide capture."
Zaman pointed out that thanks to its sulfur-containing structure, the material could also be used in water treatment in the future, and said it has the potential to absorb heavy metals like a sponge, especially for removing mercury pollution from water. He also noted that it could be utilized in gas separation and adsorption applications.
The electroactive polymer has also been registered by the Turkish Patent and Trademark Office.
