CAPACITY-MAXIMIZED PRUSSIAN WHITE FOR SODIUM-ION BATTERIES

Abstract

As promising materials for sodium-ion batteries, the development of Prussian White is vital for the commercialization of the next-generation environmentally friendly batteries. However, performance standards in current literature are still lacking in many ways, which leaves a huge gap for researchers to fill. There is a noticeable difference between the calculated theoretical specific capacity (170 mAh/g) and literature-published data (~120 mAh/g range). As of current publication, the performance of these materials are insufficient for commercial applications.

In this thesis, we set out to tie up this discrepancy by setting out two major goals, which are to: (1) enhance the capacity of a suitable cathode material (Prussian Blue), and to improve it to a competitive level such that it would be able to rival, if not exceed the performance of the incumbent lithium-ion battery systems, and (2) implement this improved material into a full-cell setup, and show that it is suitable and capable of operating as such.
