Recent research found that the main cause of lithium and nickel oxide batteries degradation is a chemical reaction involving oxygen atoms.
Researchers at the University of Texas, in Dallas, have made an innovative discovery that could make the Last Lithium Ião Batteriespotentially transforming the electric vehicle (VE) and energy storage industries.
The study, in Advanced Energy Materials, identifies the main cause of degradation of lithium and nickel oxide batteries (Linio₂) and proposes a solution to improve its stability.
Despite being recognized as a promising catholic material since the 1950s, Linio₂ has faced marketing challenges due to structural instability and rapid loss of capacity During repeated loading cycles.
These problems – caused by irreversible phase transitions, cation mixture and oxygen loss – limited their feasibility for high energy density applications such as EVs, portable electronics And large -scale energy storage systems, explains the.
Using advanced computational models, UT Dallas research team analyzed atomic level processes during the final phase of Linio₂ batteries. They found that a chemical reaction that involves oxygen atoms leads to the instability of the material, causing cracks that degrade performance. To solve this problem, they propose the reinforcement of the cathode with positive load ions, or cation, which would act as structural “pillars” To avoid degradation and improve durability.
“Now that we have a clear understanding of why this happens, we are working on a solution so that technology can be used to Provide longer battery life In a series of products, including telephones and electric vehicles. ”
This research is part of the initiative BEACONSlaunched in 2023, which focuses on the advance of battery technology. As part of this initiative, doctoral researcher Matthew Bergschneider is creating a robotics -based laboratory to develop and test battery prototypes. Initially, small -scale production will improve the process of synthesis of materials before increasing the scale to manufacture hundreds of batteries per week.
