help me to polish my article "PVDF-based SPEs still suffer their primary limitations"

PVDF-based solid polymer electrolytes (SPEs) continue to grapple with their fundamental constraints. Despite their potential, these materials face persistent challenges that hinder their widespread application. It is essential to address these limitations to unlock the full potential of PVDF-based SPEs.

One of the key drawbacks is the limited ionic conductivity of PVDF-based SPEs. This hampers their effectiveness in facilitating efficient ion transport, impacting the overall performance of energy storage devices. Enhancing the ionic conductivity should be a primary focus of future research and development efforts in this field.

Moreover, issues related to mechanical strength and flexibility pose additional hurdles. PVDF-based SPEs often exhibit inadequate mechanical properties, limiting their application in flexible and portable devices. Addressing this limitation requires innovative approaches to enhance the mechanical strength and flexibility of these materials without compromising other essential properties.

Another critical aspect that demands attention is the thermal stability of PVDF-based SPEs. These materials may face challenges in maintaining stability at elevated temperatures, which is crucial for various applications, including high-performance batteries. Strategies to improve thermal stability should be explored to broaden the scope of applications for PVDF-based SPEs.

In conclusion, while PVDF-based SPEs hold promise
