Bu
çalışma, günümüzde enerji sistemlerinin daha yüksek kapasiteli ve performanslı
üretilmesini sağlayabilecek ters opal metodunun piller üzerindeki kapasite
artışını göstermektedir. Ters opal metodu ile yeniden şarj-edilebilir pil
elektrotlarının kapasitelerinin yaklaşık 2.5 kat arttığı ve bu artış
sağlanırken daha küçük boyutlu ve daha ince katmanlı elektrotların
hazırlanabildiği görülmüştür. Ters opal metodu ile elektrotlar homojen 3D
boşluklu bir yapıya sahiptir. Bu metot ile küresel boşluklu yapıda daha yüksek
yüzey alanına sahip ve kullanılan opallerin çaplarına bağlı olarak nanometre
seviyesinde elektrot tabakaları oluşturmaktadır. Ters opal metodunda üretilen
nanometre seviyesindeki kalınlığa sahip bu yapılar ayrıca iyon transferini
hızlandırarak pillerin daha hızlı şarj edilmesi imkânı da sağlamaktadır.

Enhancement Performance of Rechargeable Batteries via Homogenous 3D Nano Cavity Structure

Öz

This
study shows the capacity improvement of the battery by inverse opal method,
which can provides to produce much effective energy systems with higher
capacity and performance. It has been seen that the capacity of the
rechargeable battery electrodes is increased by about 2.5 times via inverse
opal method, which method also provides smaller and thinner layered electrode
production. The electrodes have homogeneous 3D cavity structure via inverse
opal method. The spherical cavity structure has higher surface area and what
forming electrode layers at the nanometer levels depending on the diameters of
the used opals. These structures also provide speed up ion transfers and faster
charging of the batteries by nanometer level of thickness via inverse opal
method.
