dc.description.abstract | 影響二氧化錫電極之比電容量包含了三大
因素:粉體之表面積、粉體之孔洞分布、
粉體之結晶度。隨著熱處理溫度之升高,
粉體之晶粒大小亦隨之成長,較高結晶度
有助於粉體導電度之提高。其孔徑大小逐
漸變大,較大之孔洞有助於電解質中離子
之傳導。但此過程中,可供離子吸附以產
生電荷分離之比表面積卻隨之減少。此三
因素之間相互影響,並無法同時兼顧,因
此其中必定存在一個最適當之條件。由實
驗結果,我們可得知的是,在最適溫度
500
o
C 下進行熱處理,可以取得最大的可供電化學反應表面積。 | zh_TW |
dc.description.abstract | This research focuses on the
preparation of sol-gel derived Sb-doped
SnO2 xerogel and aerogel with high surface
area. By mixing these powders with binder
and then coating on substrate, the
performance of the film electrode of a
supercapacitor in conjunction with KOH
electrolyte have been evaluated. Powders
heat-treated at temperatures below 400 o C
exhibited strongly distributed-capacity
phenomenon due to their small pores.
Powders heat-treated at temperatures above
600 o C have low capacity due to their small surface area. The optimum heat-treatment
temperature for maximum capacitance is ~
500 o C | en |
