摘要

本发明关于一种可实现高功率或高容量的二次电池。;本发明的二次电池(100)系具备：负极(20)、正极(10)及隔离层(30)，正极(10)含有p型半导体材料，隔离层(30)使负极(20)与正极(10)隔离，并含有电洞传递部件，隔离层(30)藉由涂布在负极(20)及正极(10)中之至少一者来层叠。以电洞传递部件含有α氧化铝为较佳。以隔离层(30)含有与负极(20)或正极(10)之黏着剂相同的黏着剂为较佳。; a positive electrode containing a p-type semiconductor material; and an isolation layer configured to isolate the negative electrode from the positive electrode and including a hole transmission member. The isolation layer is layered by being applied to at least one of the negative electrode and the positive electrode. Preferably, the hole transmission member contains α-alumina. Preferably, the isolation layer includes the same binding agent as the negative electrode or the positive electrode.
