摘要:
Methods are provided for forming films of orthorhombic V 2 O 5 . Additionally provided are the orthorhombic V 2 O 5 films themselves, as well as batteries incorporating the films as cathode materials. The methods use electrodeposition from a precursor solution to form a V 2 O 5 sol gel on a substrate. The V 2 O 5 gel can be annealed to provide an orthorhombic V 2 O 5 film on the substrate. The V 2 O 5 film can be freestanding such that it can be removed from the substrate and integrated without binders or conductive filler into a battery as a cathode element. Due to the improved intercalation properties of the orthorhombic V 2 O 5 films, batteries formed using the V 2 O 5 films have extraordinarily high energy density, power density, and capacity.
摘要(中):
提供了形成斜方晶V2O5薄膜的方法。 另外提供了斜方晶V2O5膜本身以及将膜作为阴极材料的电池。 该方法使用前体溶液的电沉积在基底上形成V 2 O 5溶胶凝胶。 可以对V2O5凝胶进行退火,以在衬底上提供斜方晶V2O5膜。 V2O5膜可以是独立的,使得其可以从基底上移除并且将粘合剂或导电填料整合成电池作为阴极元件。 由于正交V2O5膜的嵌入性能的改善,使用V2O5薄膜形成的电池具有极高的能量密度,功率密度和容量。
