PVDF : The Industry-Standard Binder for Lithium-Ion Battery Cathodes, Now Available in Indonesia

PVDF is the standard polymer used as a binder in nearly every commercial lithium-ion battery in the world, ever since this technology was first developed, not because there's no alternative, but because PVDF is one of the few polymers that stays chemically stable in the extreme oxidative environment at a high-voltage cathode surface, above 4 volts versus Li/Li⁺, conditions that would degrade most other polymers in a short time. The PVDF Powder discussed here is Solef 5130, one of the most globally recognized battery-grade PVDF products for electrode applications.

Getting genuine battery-grade PVDF like Solef in Indonesia has typically meant a long import process, with the added risk that what arrives isn't actually battery grade at all, but ordinary technical-grade PVDF not designed for long-term electrochemical stability. That's starting to change.

ITNANO (CV. Inovasi Teknologi Nano), based at the NRE Lab in Medan, provides direct access to PVDF Solef 5130 in Indonesia, complete with verifiable official specifications. Here's what PVDF actually is, why its chemical stability matters, and where it's being used in research and industry today.

What Is PVDF?

PVDF (polyvinylidene fluoride) is a fluorinated polymer with a carbon chain interspersed with fluorine atoms, an arrangement that gives PVDF very high chemical resistance to solvents and oxidative environments, along with good thermal stability. This property is exactly what allows PVDF to stay bonded to cathode active material particles without degrading, even after hundreds of battery charge-discharge cycles.

Purity and molecular weight are the biggest factors in PVDF's performance as a binder, since both affect adhesion strength and solution viscosity when mixed with active material and solvent. ITNANO's PVDF is Solef 5130 grade at above 99.5% purity, with a density of 1.77-1.79 g/cm³, a melting point of 164-174°C, an intrinsic viscosity of 1-2 dL/g, a moisture content of 0.1%, and a molecular weight of 600,000 g/mol, dissolving clear in polar solvents.

Where PVDF Is Being Used

Binder for battery and supercapacitor electrodes

This is PVDF's primary application: as a binder that holds active material particles, conductive additives, and current collector together into a single sturdy electrode layer, able to withstand mechanical stress and an aggressive chemical environment throughout the lifecycle of a lithium-ion battery or supercapacitor.

Why Get Genuine PVDF from ITNANO

Because of battery-grade PVDF's reputation as an industry standard, like Solef, generic technical-grade PVDF products sold with claims of equivalence often circulate on the market, even though their molecular weight and purity aren't designed for long-term stability in an electrochemical environment. ITNANO provides PVDF with directly verifiable specifications, giving labs in Indonesia certainty that the binder they use is genuinely equivalent to the battery industry standard, without needing to wait through a long import process.

Whether you're formulating lithium-ion battery cathode electrodes, developing supercapacitor electrodes, or working on applications that require a chemically resistant binder, ITNANO's PVDF gives you an assurance of authenticity and specification that imitation products can't guarantee, without the import wait. See ITNANO's Binder product line for current specifications and pricing.
