Revolutionizing EV Batteries: Innovative New Binder Doubles Performance

Credit: Noriyoshi Matsumi from JAISTResearchers have actually created an advanced binder for silicon oxide electrodes in lithium-ion batteries, improving their electrochemical efficiency and lifespan.Lithium-ion batteries are widely used in numerous applications however require enhanced binders to enhance their performance to meet developing needs. Reliable binders are hence essential to attend to these issues and ensure enhanced performance and extended sturdiness for lithium-ion battery systems.In a recent research study published in the journal ACS Applied Energy Materials on February 8, 2024, Professor Noriyoshi Matsumi from the Japan Advanced Institute of Science and Technology (JAIST), along with doctoral student Noriyuki Takamori, previous Senior Lecturer Rajashekar Badam, Dr. Tejkiran Pindi Jayakumar (previous student), and researchers from Maruzen Petrochemical Company Ltd., have actually used poly(vinylphosphonic acid) (PVPA) as a binder for a micro-SiO electrodes, achieving superior performance compared to standard cells.Superior Performance of PVPAAccording to Prof. Matsumi, “The PVPA binder should show to be very beneficial in extending the life of high-performing lithium-ion secondary batteries. The use of PVPA will use better options to commercially available binders, such as poly(acrylic acid) (PAA) and poly(vinylidene fluoride) (PVDF), etc”The research study involved fabricating electrodes containing PVPA, PAA, and PVDF as binders, and their performance was evaluated through electrochemical experiments and density functional theory.
