No ka pana ʻana i ka palena o ka ikehu o nā super-capacitors, makemake nui ʻia kahi papa hou o nā mea electrode me nā hale hoʻolālā maikaʻi.
ʻO nā sulfides metala binary e paʻa i ka ʻōlelo hoʻohiki nui ma ke ʻano he mea electrode no nā mea mālama mālama ikehu hana kiʻekiʻe no ka mea hāʻawi lākou i ka hana electrochemical kiʻekiʻe a me ka mana kiʻekiʻe ma mua o ka mono-metal sulfides.
Maanei, ua hōʻike ʻia ka hoʻolālā kūpono a me ka hana ʻana o nā nano-sheets NiCo 2 S 4 i kākoʻo ʻia ma nā foams carbon doped nitrogen (NCF) (e pili ana i ka SINOYQX carbonized melamine foam) ma ke ʻano he electrode flexible hou no nā super-capacitors.
Ua hoʻomohala ʻia kahi ʻano hana maʻalahi ʻelua-ʻanuʻu no ka ulu ʻana o nā nanosheets NiCo 2 S 4 ma NCF me ka hoʻopili paʻa, e pili ana i ka ulu ʻana o ka mea mua o Ni-Co a me ka hoʻololi ʻana ma hope i nā nanosheets NiCo 2 S 4 ma o ke kaʻina hana sulfidation.
Me ka pōmaikaʻi mai nā hiʻohiʻona haku mele a me nā hoʻolālā electrode 3D, hōʻike ka electrode NiCo 2 S 4 /NCF i ka hana electrochemical i hoʻomaikaʻi nui ʻia me ka capacitance ultrahigh (877 F g −1 ma 20 A g −1 ) a me ke kūpaʻa paikikala maikaʻi loa.
Eia kekahi, ua hana ʻia kahi mea hoʻohuihui super-capacitor asymmetric ʻole ma ka hoʻohana ʻana iā NiCo 2 S 4 /NCF ma ke ʻano he electrode maikaʻi a me ke kalapona mesoporous i kauoha ʻia (OMC) / NCF ma ke ʻano he electrode maikaʻi ʻole; hōʻike kēia i ka nui o ka ikehu (≈45.5 Wh kg −1 ma 512 W kg −1 ).
No ka ʻike hou aku e pili ana i ka papahana, e ʻoluʻolu e hoʻokaʻaʻike iā SINOYQX ma o: [email protected] a i ʻole leka uila ma [email protected] Laifa Shen, Jie Wang, Guiyin Xu, Hongsen Li, Hui Dou lāua ʻo Xiaogang Zhang mai ke Kulanui o ka ʻEpekema Mea a me ka ʻenekinia Jiangsu Key Laboratory of Materials and Technologies for Energy Conversion, Nanjing, PR Kina No ka hoʻokuke ʻana i ka palena o ka nui o ka ikehu o nā super-capacitors, pono nui kahi papa hou o nā mea electrode me nā hoʻolālā maikaʻi.
