CATEGORY: Binders & Specialty Coating Materials for Lithium Ion Batteries
Lithium ion batteries are one of the world’s most progressive technologies, powering everything from cell phones to electric cars. In order to provide a battery that delivers great performance while still maintaining a high level of safety, the quality of the materials used and proper processing are crucial. APV has the capability to disperse a diverse range of solvents with high performance binders, such as N-Methyl 2-Pyrrolidone (NMP) and Polyvinylidene Fluoride (PVDF), for customized aqueous slurry materials used in electrode preparation. We procure battery grade components and instill processing techniques that produce a binder or slurry that is pure, free of contaminants and moisture, and completely dispersed with uniform particle size distribution. Processing methods range from high and low shear mixers, which are controlled with exceptional filtration systems.
Depending on formulation requirements, APV has a variety of high and low shear mixers including high speed reactors, dual shaft mixers, three-roll mills, horizontal mills and ball mills. Binders and slurries are manufactured under an inert gas blanket to maintain purity levels. The blending process is highly controlled by a technical team analyzing quality, maintaining consistency, and eliminating performance issues such as gelling, seeding, poor particle distribution, discoloration, trapped moisture, etc.
APV can provide battery grade solvents including N-Methyl 2-Pyrrolidone (NMP) for the manufacturing of electrode binders and slurries. The procurement of the highest grade materials assures optimal performance and product consistency. Purity levels are tested using a titration method and are maintained through processing under an argon gas.
APV can disperse a variety of high performance resins, polymers, and elastomers, such as SBR or PVDF. PVDF is a common binder material used in electrode preparation due to its high molecular weight and surface chemistry. These properties help to improve adhesion of the electrodes to the collector as well as affect the level of coverage over the active materials in the lithium ion cell.
Unlike other suppliers, APV offers the ability to source and incorporate high performance additives into anode/cathode coating slurries for a ready-to-use/ready-to-coat format. This includes carbon black, single and multi-wall carbon nanotubes, graphene, and graphite. These additives are often utilized to improve cycling efficiency, increase energy storage life cycles, and enhance performance.
