Tumen: Loaʻa iā mākou nā supercapacitors e like me nā pākahi lithium-ion. ʻOi aku ka maikaʻi
ʻO ka hui Kina ʻo Toomen New Energy ka mea i loaʻa nā supercapacitors i loaʻa ka ikehu o nā pā lithium-ion. I ka manawa like, e like me nā supercapacitors, hiki iā lākou ke ʻae a hoʻokuʻu i nā uku kiʻekiʻe ma mua o nā pā lithium-ion. Ma ka liʻiliʻi ma ka pepa, hoʻomaikaʻi kēia i ka hana kaʻa a me ka hana hoʻouka.
Supercapacitors ma kahi o nā pila? A i ʻole ke kūʻai aku paha?
Ka papa o nā mea
- Supercapacitors ma kahi o nā pila? A i ʻole ke kūʻai aku paha?
- ʻO kekahi Hummingbird?
Ua lawe ʻia nā supercapacitors i nīnau ʻia i ʻEulopa e ka Belgian Eric Verhulst. ʻIke ʻia, ʻaʻole ʻo ia i manaʻoʻiʻo i ka mana i haʻi ʻia e ka mea hana, no ka mea he iwakālua mau manawa ʻoi aku ka maikaʻi ma mua o nā palena i hoʻohiki ʻia e Maxwell. Hoʻohui mākou ʻo Maxwell kekahi o nā alakaʻi i ka mākeke supercapacitor a ua kūʻai ʻia e Tesla ma 2019 (kumu).
> Loaʻa iā Tesla iā Maxwell, kahi mea hana o nā supercapacitors a me nā ʻāpana uila
Ke haʻaheo nei ʻo Verhulst e hiki i nā supercapacitors Kina ke kū i ka hoʻopaʻa ʻana ma 50 C (50x hiki), a i kekahi mau mahina ma hope o ka hoʻopiʻi ʻana, paʻa mau lākou i kahi uku, ʻaʻole maopopo loa me nā supercapacitors. Eia kekahi, ua hoʻāʻo ʻia lākou e ke Kulanui o Munich, a i kēia mau hoʻāʻo ua hiki iā lākou ke kū i nā mahana mai -50 a +45 degere Celsius.
Hoʻomaopopo ka mea hana Kina ua hoʻohana ʻo ia i ka "carbon activated" i kāna mau supercapacitors, akā ʻaʻole maopopo i ke ʻano o ia mea. Ua hōʻike ʻo Belgian ua hoʻomohala ʻo Toomen i kahi packet supercapacitor me ka nui o ka ikehu o 0,973 kWh / L. ʻOi aku kēia ma mua o nā pūnaewele lithium-ion maʻamau, a ʻoi aku hoʻi ma mua o ka prototype solid electrolyte cell i wehewehe ʻia e Samsung SDI.
> Ua hoʻokomo ʻo Samsung i nā cell electrolyte paʻa. Wehe: ma 2-3 mau makahiki ma ka mākeke
Ua hōʻike ʻia ʻo nā supercapacitors maikaʻi loa mai ka mea hana Kina i hōʻea i ka ikehu ikehu o 0,2-0,26 kWh / kg, ʻo ia hoʻi, ʻaʻole i ʻoi aku ka maikaʻi o kā lākou mau ʻāpana ma mua o nā pā Li-ion hou.
Akā ʻaʻole ʻo ia wale nō. Hoʻomaopopo ka Belgian aia nā Toomen supercapacitors i hoʻolālā ʻia e loaʻa / hoʻokuʻu i nā mana kiʻekiʻe. Hāʻawi lākou i kahi haʻahaʻa haʻahaʻa haʻahaʻa (0,08-0,1 kWh / kg), akā e ʻae i ka hoʻouka ʻana a me ka hoʻokuʻu ʻana ma 10-20 C. I ka hoʻohālikelike ʻana, hāʻawi nā pā i hoʻohana ʻia i ka Tesla Model 3 i ka nui o ka ikehu ma luna o 0,22 kWh. / kg (per. ke kiʻekiʻe o ka pākaukau) me ka mana hoʻouka o 3,5 C.
ʻO kekahi Hummingbird?
ʻIke maikaʻi loa nā ʻōlelo hoʻohiki a Toomen New Energy ma ka pepa. Hōʻike nā ʻāpana i wehewehe ʻia e hiki i nā supercapacitors o ka mea hana Kina ke hoʻololi i nā pila, a i ʻole e hoʻohui iā lākou. Hiki i ka mana hikiwawe ke hāʻawi i ka wikiwiki ma lalo o 2 kekona a i ʻole ka hoʻouka ʻana mai 500 a 1 kW..
ʻO ka pilikia, ʻo kā mākou hana wale nō me nā ʻōlelo hoʻohiki. Ua ʻike ka mōʻaukala i nā mea hana "breakthrough", i lilo i mea hoʻopunipuni. Aia ma waena o lākou nā pihi Hummingbird:
