PVDF is a chain polymer, its molecular weight is generally greater than 300,000, and it is an insulator. The bonding mechanism is to form hydrogen bonds through the F atoms on the long chain and other component particles in the pole piece, and the effect of hydrogen bonds makes each component particle string together.<\/p><p><img loading=\"lazy\" decoding=\"async\" class=\"aligncenter size-full wp-image-59169\" src=\"https:\/\/www.takomabattery.com\/wp-content\/uploads\/2022\/11\/PVDF-battery-binder.jpg\" alt=\"PVDF battery binder\" width=\"1000\" height=\"750\" srcset=\"https:\/\/www.takomabattery.com\/wp-content\/uploads\/2022\/11\/PVDF-battery-binder.jpg 1000w, https:\/\/www.takomabattery.com\/wp-content\/uploads\/2022\/11\/PVDF-battery-binder-300x225.jpg 300w, https:\/\/www.takomabattery.com\/wp-content\/uploads\/2022\/11\/PVDF-battery-binder-768x576.jpg 768w, https:\/\/www.takomabattery.com\/wp-content\/uploads\/2022\/11\/PVDF-battery-binder-600x450.jpg 600w\" sizes=\"(max-width: 1000px) 100vw, 1000px\" \/><\/p><p>In PVDF battery binder modification, blending modification is simple and effective. Generally, another polymer is mixed with PVDF to obtain a battery binder with better performance. The modified battery binder after blending generally shows that the crystallization of PVDF is appropriately reduced, the composite electrode is more compatible with the electrolyte, the lithium ion transmission is accelerated, and the battery performance is improved.<\/p><p><strong>\u25cf Other oil-based binders<\/strong><\/p><p>In addition to the commonly used PVDF battery binder, other oil-soluble binders have also received a lot of attention through their unique advantages. Non-PVDF oily binders mainly include: polyacrylonitrile (PAN), polyimide (PI), perfluorosulfonic acid ionomer (Nafion).<\/p><p>PAN is a semi-crystalline polymer, and its main functional group, the nitrile group, has strong polarity, and generally connects active materials and current collectors through hydrogen bonds, van der Waals forces, and permanent dipole-dipole interactions. At the same time, PAN can well infiltrate the electrolyte, and the strong polarity of the nitrile group can also promote the movement of lithium ions in the electrode.<\/p><p>PI-based battery binder generally has good mechanical properties and heat resistance, and are often used in large-volume expansion silicon anodes and high-voltage layered cathode materials.<\/p><p>Nafion has excellent ionic conductivity and suitable bonding strength. The sulfonic acid group on Nafion can generate electrostatic interaction with Li+ in the electrolyte, so that Li+ can creep and migrate on the polymer main chain, improving the ionic conductivity of the electrode.<\/p><h3 id=\"Water-based-battery-binder\">Water-based battery binder<\/h3><p>In order to overcome the problems of environmental pollution and high cost of use of oily battery binder, water-soluble battery binder has been gradually developed, and have become a direction that battery workers have generally paid attention to in recent years. Water-based battery binder widely used in industrial lithium-ion batteries include sodium carboxymethylcellulose (CMC) combined with styrene-butadiene rubber (SBR), polyacrylate (LA series) binders, etc.<\/p><p><strong>\u25cf CMC<\/strong><\/p><p>The preparation of CMC is formed by embedding carboxymethyl functional groups into natural cellulose. Due to the presence of carboxymethyl functional groups in CMC, it is soluble in water. When CMC is used as a carbon negative electrode binder for lithium-ion batteries, the amount used is relatively small, generally between 2% and 5%.<\/p><p>The electrode made with this binder has a small loss in the first irreversible capacity and a high reversible capacity. Some companies have applied CMC in the manufacture of lithium-ion negative electrodes, but CMC is brittle and has poor flexibility.<\/p><p><strong>\u25cf SBR<\/strong><\/p><p><img loading=\"lazy\" decoding=\"async\" class=\"aligncenter size-full wp-image-59170\" src=\"https:\/\/www.takomabattery.com\/wp-content\/uploads\/2022\/11\/Lithium-battery-binder-SBR.jpg\" alt=\"Lithium battery binder SBR\" width=\"1000\" height=\"563\" srcset=\"https:\/\/www.takomabattery.com\/wp-content\/uploads\/2022\/11\/Lithium-battery-binder-SBR.jpg 1000w, https:\/\/www.takomabattery.com\/wp-content\/uploads\/2022\/11\/Lithium-battery-binder-SBR-300x169.jpg 300w, https:\/\/www.takomabattery.com\/wp-content\/uploads\/2022\/11\/Lithium-battery-binder-SBR-768x432.jpg 768w, https:\/\/www.takomabattery.com\/wp-content\/uploads\/2022\/11\/Lithium-battery-binder-SBR-600x338.jpg 600w\" sizes=\"(max-width: 1000px) 100vw, 1000px\" \/><\/p><p>When SBR is used as a battery binder, it has good elasticity and high elongation, and is mainly used to increase the flexibility of the electrode sheet. In industry, SBR is mostly used in combination with CMC. The mechanical properties of polymer films with different CMC\/SBR ratios are shown in the figure below. It can be seen that SBR effectively reduces the Young&#8217;s modulus of the film and increases the flexibility of the film.<\/p><p><strong>\u25cf LA series<\/strong><\/p><p>Polyacrylate latex has good adhesion to current collectors, which is conducive to improving the capacity of electrodes, and has been used in some applications in recent years. The first reversible specific capacity and cycle performance of the nano-SnO2 pole piece fabricated in this way are improved compared with the use of PVDF battery binder.<\/p><p>The disadvantage of this type of battery binder is its high brittleness in dry conditions. During the pulping process, the active material is prone to agglomeration and has poor dispersion. It may be that the stability of the binder makes the long-term cycle performance of the electrode sheet made of this battery binder poor.<\/p><p><strong>\u25cf PAA<\/strong><\/p><p>PAA as a battery binder has the following advantages:<\/p><p><span style=\"color: #808000;\">\u25cf<\/span> There is almost no swelling in the carbonate solvent of the electrolyte, and the structure of the electrode sheet is stable during the charge and discharge process;<\/p><p><span style=\"color: #808000;\">\u25cf<\/span> The carboxyl group content in its structure is higher than that of CMC, which can form a strong hydrogen bond with active material materials (such as silicon anode materials) containing hydroxyl groups on the surface, and promote the formation of a more uniform coating on the electrode surface than CMC ;<\/p><p><span style=\"color: #808000;\">\u25cf<\/span> It can form a relatively dense film in the electrode sheet, increasing the electrical contact between the active material and the current collector;<br \/>Excellent tensile mechanical strength, which is conducive to
