主 题：Functional binders Molecular design High-specific-energy electrodes Lithium-ion batteries
摘 要：The binder adheres to each component of the electrode to maintain the structural integrity and plays an irreplaceable role in a battery despite its low *** difluoride(PVDF),as the dominant binder in commercial battery systems(for cathodes),has acceptably balanced properties between chemical/electrochemical stability and adhesive ***,in the pursuit of high-specific-energy batteries featuring high mass loading,high voltage,and large volume changes,the PVDF binder is unable to satisfy the versatile electrode demands and extreme operation ***,developing novel binders with task-specific functionality is of urgent ***,we review the recently developed design strategies of functional binders from the insight of molecular *** functions and failure mechanisms of the binders are elucidated *** from the basic moiety(functional group)of the polymer molecule,how the constituents,molecular structure,and assembly into a supramolecule will affect the properties of the binders,and furthermore the performance of the electrodes,is discussed at ***,we summarize and provide a future outlook on the opportunities and challenges of functional binders towards future high-specific-energy lithium-ion batteries.
