ʻEkolu mau pono nui o ka pākaukau mālama ikehu, ʻo ka palekana ka mea koʻikoʻi
Manaʻo ʻia ka mālama ʻana i ka ikehu electrochemical ʻo ia ke ʻano nui o ka mālama ʻana i ka ikehu i ka ʻōnaehana mana e hiki mai ana, ʻo ka pākaukau a me ka PCS ka waiwai kiʻekiʻe a me nā mea pale i ke kaulahao ʻoihana, ʻo ke koi nui aia i ka palekana kiʻekiʻe, ke ola lōʻihi a me ke kumukūʻai haʻahaʻa. I waena o lākou, ʻo ka palekana ke kī. Wahi a kekahi poʻe akamai o ka ʻoihana, i kēia manawa ke ulu wikiwiki nei ka mana mālama uila electrochemical, akā ʻo ka pilikia palekana ka bottleneck o kāna hoʻomohala nui, ʻo Beijing ka ikehu waihona mana a me Tesla Australia ikehu waihona pāhana no ka pahū ʻana no ka ʻoihana mālama ikehu ua kani ka puʻupuʻu.
No kēia hopena, nā Manaʻo alakaʻi e pili ana i ka hoʻonui ʻana i ka hoʻomohala ʻana o ka New Energy Storage e hoʻokumu i ka hoʻokumu ʻana i nā kūlana ʻenehana palekana a me ka ʻōnaehana hoʻokele, hoʻoikaika i ka mālama ʻana i ke ahi, e mālama pono i ka laina lalo palekana e like me ke kumu kumu; i ka palekana kiʻekiʻe, ke kumukūʻai haʻahaʻa, ka hilinaʻi kiʻekiʻe, ke ola lōʻihi a me nā mea ʻē aʻe o ka holomua lōʻihi; hoʻoikaika i ka palekana o ka noiʻi ʻenehana mālama ikehu electrochemical a pēlā aku. National Development and Reform Commission, ka National Energy Board e hoʻonohonoho i ka hoʻolālā ʻana o ka "Interim Measures for the Safe Management of Electrochemical Energy Storage Stations (Draft)", ua hoʻi ma ʻAukake 24th i ke kaiāulu no ke kūkākūkā lehulehu, e hoʻoikaika i ka hoʻokele ʻana i ka palekana mālama mālama.
Palekana kiʻekiʻe, ola lōʻihi, nickel-metal hydride waiwai nui
Hōʻike ka ʻikepili ʻo China Battery Industry Association i ka nickel-metal hydride uila palekana, lōʻihi ka pōʻai ola, kona electrode maikaʻi i hana ʻia i nā nickel spheres, kākoʻo ʻia ka mea hana electrode maikaʻi ʻole e ka hydrogen storage alloy, pili i kahi mea paʻa paʻa, ʻo ka wai electrolyte he mau mea pale ahi maikaʻi, ʻaʻole e pahū a puhi i nā pōʻino, ka nui o ka ikehu monomer a hiki i 14 kg; ke ola pōʻaiapuni a hiki i 3,000, hoʻopaʻu pāpaʻu a me ka hoʻokuʻu ʻana i ka mokuʻāina a hiki i 10,000 mau manawa a ʻoi aku paha; hiki ke hoʻohana ʻia ma mua o 10,000 mau manawa; hiki ke hoʻohana ʻia ma mua o 10,000 mau manawa. ʻOi aku ma mua o 10,000 mau manawa; hiki ke mālama i kahi kiʻekiʻe o ka hoʻouka ʻana a me ka hoʻokuʻu ʻana ma -40 ° C ~ 60 ° C kaiapuni. Toyota HEV kaʻa global kuai ua hiki i oi aku ma mua o 18 miliona, a me ka lako nui me ka nickel-metal hydride pila, aole i loaʻa hoʻokahi hihia o ka ulia pōʻino, ua hōʻoia piha ka palekana kiʻekiʻe o ka pila.
Eia kekahi, ʻo ka hoʻopiʻi ʻana a me ka hoʻokuʻu ʻana ka hoʻololi ʻana o ka ikehu kemika a me ka ikehu uila, he hopena nui ka mahana i ka hopena kemika. ʻO ka nui o nā keʻena mana mālama ikehu ma waho, ʻo ka hapa nui o nā ʻano pākaukau e hoʻopilikia ʻia e ke kaiapuni a me ka mahana, e kaupalena ana i kahi o nā kikowaena mana a hoʻonāwaliwali i ka hana o ka mālama ʻana i ka ikehu. Nickel-metal hydride batteries i loko o ka haʻahaʻa loa wela a me ke kiʻekiʻe wela hoʻopiʻi maikaʻi a me ka hoʻokuʻu 'ana i ka pono, no laila, i ka ikehu waihona mana kahua kahua oi maʻalahi, maʻalahi, maikaʻi holoʻokoʻa hana, i lilo i kona komo ana i loko o ka hoʻokûkû o 'okoʻa 'ike loea ala ala "me nā helu".
ʻO ka ʻoiaʻiʻo, ʻo nā pākahi nickel-metal hydride i ka noi ʻana o ka mākeke mālama ikehu he mea mua. 2020, nickel-metal hydride battery storage company Nilar e ka European Investment Bank he 47 miliona mau kālā. Ua hoʻomaopopo ʻia ʻo Nilar e kālele ana i ka hoʻohui ʻana i ka mana hou a me ka mālama ʻana, ka mana standby a me ka hoʻouka ʻana i nā noi kaʻa uila, ʻo ka hoʻopukapuka ʻana e hoʻolaha i ka hui e hoʻohui ʻia i loko o ka pākaukau no nā hale noho, ʻoihana a me nā ʻoihana a me nā ʻōnaehana mākeke a i ʻole nā mea waiwai. Wahi a Frontiers in Polymer Science, ua hoʻomohala ka hui o Professor Yi Cui ma ke Kulanui ʻo Stanford i kahi pākahi nickel-metal hydride (Ni-MH) no ka nui o ka ikehu hou a me ka mālama ʻana i nā noi, me nā pōmaikaʻi o ke ola lawelawe lōʻihi loa, ʻaʻohe pilikia o ke ahi a i ʻole ka holo ʻana o ka wela, ʻaʻohe pono no ka mālama maʻamau, ʻano haʻahaʻa haʻahaʻa maikaʻi, a me nā kumu kūʻai haʻahaʻa. E kūkulu ka hui o Cui i kahi pailaka me ka nui o 2 megawatts i ka makahiki 2021, a ke manaʻo nei e hoʻonui i kona hiki i 20 mau manawa ma mua o 2022.
