چکیده

پلیمر پلی‌وینیلیدن فلوئورید (PVDF) پلیمری نیمه‌بلوری است که به‌علت ویژگی‌های مطلوبی چون خواص دی‌الکتریکی عالی، استحکام مکانیکی مناسب، پایداری گرمایی زیاد، مقاومت شیمیایی خوب و همچنین قابلیت تشکیل غشا به‌طور گسترده در پژوهش‌های علمی و فرایندهای صنعتی استفاده می‌شود. غشاهای PVDF کاربردهای متنوعی در زمینه تصفیه آب، جداسازی گاز و نیز به‌عنوان جداساز و الکترولیت پلیمری در باتری یون لیتیم دارند. جداساز استفاده‌شده در باتری یون لیتیم باید دارای ضخامت کم و اندازه تخلخل و منافذ مناسب با استحکام مکانیکی خوب باشد. الکترولیت پلیمری بر پایه PVDF به‌علت پایداری الکتروشیمیایی در باتری یون لیتیم به‌عنوان ماده مناسبی برای ساخت جداکننده‌ها استفاده می‌شود. با وجود این، پلیمر PVDF خالص استفاده‌شده در آماده‌سازی الکترولیت پلیمری ممکن است باعث ایجاد اتصال کوتاه شود که بر عملکرد باتری اثر می‌گذارد. آمیخته‌سازی با سایر پلیمرها و افزودن پرکننده‌های معدنی و نانوذرات از روش‌های مؤثر برای بهبود عملکرد الکترولیت‌های پلیمری هستند. در این مقاله، الکترولیت‌های پلیمری بر پایه PVDF و الزامات عملکردی آن‌ها بررسی شده است. همچنین، روش‌های ساخت این الکترولیت و راهکارهای شناخته‌شده برای بهبود ویژگی‌های مکانیکی و الکتروشیمیایی آن‌ها شرح داده شده است. افزون بر این، رسانندگی یونی و عملکرد الکتروشیمیایی باتری یون لیتیم بر پایه PVDF نیز بحث می‌شود.

چکیده [English]

Polyvinylidene fluoride (PVDF) is a semicrystalline polymer which has been extensively
applied in scientific research and industrial processes owing to its desirable features
such as excellent dielectric properties, suitable mechanical resistance, high thermal stability,
good chemical resistance. PVDF membranes can be applied in a wide range of applications
including waste water treatment, gas separation, and separator and polymer electrolyte in
lithium ion batteries. PVDF-based polymer electrolytes in lithium ion batteries should have
low thickness as well as an appropriate porosity with good mechanical strength and high
electrochemical stability. Applying pristine PVDF based polymer electrolytes may cause
internal short circuit which will influence the performance of the Li-ion batteries. Blending
PVDF with other polymers and incorporation of inorganic fillers have been considered as
effective methods to improve the performance of PVDF-based electrolytes. In this paper,
PVDF-based electrolytes and their performance requirements have been investigated. The
fabrication methods of PVDF membranes and the known strategies which are applied to
improve their mechanical and electrochemical characteristics have also been described.
Furthermore, the ionic conductivity and electrochemical performance of PVDF-based
lithium-ion batteries are discussed.
