Solef® PVDF Improves Battery Performance

Solvay - Solef PVDF in batteries

Lithium batteries are a challenging application for most polymeric materials, as they demand long-term reliability as well as chemical and electrochemical resistance in the specific chemical environment of Li-ion cells. In the case of automotive applications, higher temperature performance is also required.

Solef® PVDF brings many advantages to the lithium battery industry when used as a binder in the formulation of electrodes as well as in the design of the separator: as a binder, it provides outstanding adhesion and long-term performance; as a separator coating, it enhances the interface between electrode and separator. All these allow our customers to achieve a smoother cell assembly process to produce higher energy density cells with increased cycle life.

Solef® PVDF is already well-assessed in many specialty applications such as oil and gas, semiconductors, membranes for water filtration, plumbing, architectural coatings, and photovoltaics.

Key Characteristics for Li-ion batteries

-Solef PVDF is electrochemically stable in the full range of voltage between 0 and 5 V vs Li+/Li, which guarantees its safe use in the electrochemical environment of the lithium cell.

-Thermogravimetric analysis shows that Solef PVDF resins are stable at high temperature: no thermal degradation occurs below 420°C (788°F) for short-term treatments.

-The shelf life of Solef PVDF is infinite. In accordance with ISO 9080 extrapolation standards, Solef PVDF pipes are stable for more than 50 years under 25 MPa at room temperature.

Binders for Stable Electrodes

Among other polymers, Solef PVDF is one of the preferred choices as a binder material for electrodes thanks to its stable and reliable performance.

In particular Solef PVDF guarantees:

-Electrochemical stability from 0 to 5 V vs Li+/Li

-Solubility in NMP for easy processing

-Chemical resistance in the electrolyte

-Suitable cohesion between active materials

-Durable adhesion to the current collector

Solef PVDF for long term batteries

Adhesion is a key property that determines the final performance of batteries, especially in the long term. A good binder guarantees the homogeneous dispersion of active materials and conductive carbon together with stable bonding to the metallic collector.

Various tests have been conducted to evaluate the binder effect. In the two images the result of the comparison tests of the binding effect between Solef PVDF and a common Hydrogenated polymer.
