电化学装置
摘要：
本发明提供一种电化学装置(100)，其具备具有隔板(18)和夹住隔板(18)设置的一对电极(10、10)的叠层体(20)、和浸渍在叠层体(20)中的电解液，电极(10)含有活性物质粒子，隔板(18)由平均纤维直径Df为0.1～1.0μm的无纺布制造，将隔板(18)的厚度记为T时、满足T≥5μm且T/Df≥20，将活性物质粒子的平均粒径记为Dp时、满足Dp＜T。
摘要（英）：

In an electrochemical device 100 comprising a multilayer body 20 having a separator 18 and a pair of electrodes 10, 10 disposed so as to hold the separator 18 therebetween, and an electrolyte infiltrated in the multilayer body 20; the electrodes 10, 10 contain an active material particle; the separator 18 is made of a nonwoven fabric having an average fiber diameter Df of 0.1 to 1.0 mum; T>=5 mu mand T/Df>=20, where T is the thickness of the separator 18; and Dp
