Since the necessity of the batteries, the study of the prussian blue(PB) battery has increased fro decades of years because of its low cost, environmental friendly, high theoretical capacity, and long cycle life. Such of the features are caused by its special structure, which provides the space to storage lithium ions.
In this study, the co-precipitation method was used to produce PB. The difference is that the temperature are controlled to four different temperature during the titration process, causing the different particle size of PBs. The X-ray is also used to analyze the difference of particle size. After that, the produced, different size PBs are made into batteries to analyze. Also, nano size of nickel are added to the PB to see if the nickel will affect the batteries.
In this work, we found out that PB batteries with nano size of nickel will have worse full specific capacity when comparing with PB battery. Also, the more nano size of nickel is added, the worse the capacity is. This difference may caused by Fe-C reaction at 3.3 V. |
