The efect of different binders on the electrochemical properties of mesoporus carbon anode electrodes used in lithium ion batteries.

Lithium ion batteries are a type of rechargeable battery whose importance has been increasing in recent years. With the increasing interest in portable electronic products and the increasing popularity of electric vehicles day by day, this type of battery has also come to the forward. Lithium-ion batteries, which the changing and developing technology has given to humanity, are among the battery types used in many of today's technology-related fields. The many advantages it offers, are an important factor in the widespread use of this battery type. Lithium ion battery usage areas include many products such as mobile phones, laptops, small home appliances, tablets and electric vehicles. Lithium ion batteries; They are among the popular battery types due to their important advantages such as lightweight construction, top-notch charging, small and portable. Today, the usage area is expanding day by day. In this thesis, the effects of different binders on the electrochemical properties of mesoporous carbon(MCMB) anode electrodes used in li-ion batteries were investigated. PVDF, CMC + SBR and LA 133 were used as binders. The anodes in which binders are used are produced by mesoporous carbon based anode electrode slurry method. The produced anode muds were plastered on Cu foil with Dr Blade method and anode electrodes were obtained. The anode binding performances of the binders were demonstrated with FESEM images. The performances of the anodes are demonstrated by impedance spectroscopy, cyclic voltammetry and galvanostatic charge / discharge curves. LA 133 binder showed higher and stable specific capacity and cycle performance compared to other binders.
