Electrode materials based on metal-organic frameworks and polymers for sodium-ion batteries

This article serves as a brief review of sodium-ion technology and the possibilities of using metal-organic frameworks (MOFs) and polymer based electrodes to improve the properties of Na-ion batteries. It is clear that both MOFs and polymers offer a wide range of options for adjusting their properties in order to achieve the best possible properties for Na-ion batteries. MOFs generally offer higher capacity however lower stability during cycling on the other hand polymers offer lower capacity however lower irreversible capacity and quite good stability during cycling.
