Các nanoarray hình xương rồng Mn3O4/Co(OH)2 cho siêu tụ điện bất đối xứng có mật độ năng lượng cao
Tóm tắt
Một cấu trúc mới của nanoarray hình xương rồng Mn3O4/Co(OH)2 đã được phát triển trực tiếp trên bọt niken thông qua quy trình hai bước đơn giản, sử dụng phương pháp điện phân và phương pháp thủy nhiệt. Các hạt Mn3O4 được sử dụng làm khung để neo giữ Co(OH)2, nhằm tạo thành cấu trúc nanoarray hình xương rồng. Nhờ vào hiệu ứng cộng hưởng giữa các lớp nano Mn3O4 và Co(OH)2, điện cực Mn3O4/Co(OH)2 thu được thể hiện điện dung riêng xuất sắc là 1792.9 F g−1 ở mật độ dòng 1 A g−1. Hơn nữa, siêu tụ điện bất đối xứng Mn3O4/Co(OH)2//graphene oxide giảm đã được lắp ráp cho thấy mật độ năng lượng cao là 53.4 Wh kg−1 ở mật độ công suất 800.0 W kg−1, cùng với hiệu suất chu kỳ xuất sắc (82.5% duy trì sau 2000 chu kỳ ở 10 A g−1). Những đặc tính xuất sắc này khiến Mn3O4/Co(OH)2 trở thành ứng cử viên sáng giá cho các siêu tụ điện hiệu suất cao.
