Pāka Lithium no ka mālama ʻana i ka ikehu ma nā ʻano mea mana ʻole
ʻO ka hapa nui o nā ʻōnaehana mālama i kēia manawa a puni ka honua e hoʻohana ana i nā pā lithium.Hōʻike ka honua o nā pākahi lithium i kahi hui like ʻole o nā ʻenehana e mālama ai i ka ikehu ma o ka hoʻohana ʻana i nā ion lithium, nā ʻāpana me ka uku kūpono manuahi e hiki ke maʻalahi me nā mea ʻē aʻe.
Hana a me na ano
ʻO ka hoʻouka ʻana a me ka hoʻokuʻu ʻana o nā pā lithium, i hana ʻia me kahi electrode maikaʻi (lithium cathode) a me kahi electrode maikaʻi ʻole (carbon anode), e hana ʻia ma o nā hopena kemika e hiki ai i ka ikehu, i kēia hihia i hana ʻia e nā mea kanu hou, e hōʻiliʻili a hoʻihoʻi ʻia. .He mau hiʻohiʻona ʻenehana maikaʻi loa nā pākahi Lithium no ka manaʻo o ka ikehu, me ka modularity, ke kiʻekiʻe o ka ikehu kiʻekiʻe a me ke kiʻekiʻe o ka hoʻouka ʻana a me ka hoʻokuʻu ʻana, hiki ke ʻoi aku ma mua o 90% ma kahi pae module hoʻokahi.
ʻO ka ʻenehana e pili ana i ka nickel, manganese a me ka cobalt (NMC) ua hoʻololi ʻia i nā makahiki i hala iho nei, me ka hoʻonui ʻana i ka hana a me nā kumukūʻai i hāʻule, e like me ka ʻike Bloomberg, ma kahi o 85% mai 2010 a 2018.
Hana a me na ano
ʻO ka paʻakikī i ka loaʻa ʻana o kekahi mau mea, ʻoi aku ka cobalt, mai kahi ʻano socio-political o ka nānā ʻana, ke hoʻoikaika nei i ka poʻe noiʻi e hoʻāʻo i nā hopena hou e hōʻike ana i nā haʻahaʻa haʻahaʻa o ka cobalt, a i ʻole kahi i hui pū ʻia ai ka lithium me nā mea ʻē aʻe i maʻalahi ke loaʻa, e like me ka silicon a i ʻole. oxygen.
Eia kekahi, hoʻonui ʻia ka nānā ʻana i ka hoʻokele hopena o ke ola, ma o ke aʻo ʻana i nā kaʻina hana e hiki ai iā mākou ke "pani" i ka pōʻai hana ma ka hana hou ʻana i nā mea koʻikoʻi loa.Wahi a ka ʻikepili mai ka Global Battery Alliance, hiki i ka 11 miliona mau toni o nā ʻona lithium ion e hiki i ka hopena o ke ola ma ka makahiki 2030. Ke aʻo ʻia nei kekahi mau mea hoʻohana hou no nā pā lithium (e laʻa, no nā kaʻa uila) i hiki ke hoʻohui iā lākou i loko o nā ʻōnaehana mālama. nā ʻōnaehana hou, a i ʻole e hāʻawi i nā lawelawe no ka pā uila, e hana ana i kahi pōʻai maikaʻi o ka hoʻokele waiwai.
