ʻO nā pākahi liʻiliʻiua lilo i mea nui o ko kakou ola ana i kela la i keia la, e hoohana ana i na mea a pau mai na smartphones a me na laptops i na kaa uwila a me na nenoai hoahu ikehu hou. ʻO ka mōʻaukala o nā pā lithium he huakaʻi hoihoi i nā makahiki he nui, i hōʻailona ʻia e nā holomua nui o ka ʻenehana a me ka hana hou. Mai ka hoʻomaka haʻahaʻa a hiki i ko lākou kūlana i kēia manawa ma ke ʻano he alakaʻi i ka mālama mālama ʻana i ka ikehu, ua hoʻololi nā pākahi lithium i ke ʻano o kā mākou hoʻohana a mālama ʻana i ka uila.
ʻO ka hana ʻana o nā pā lithium
Ka moolelo onā pākahi lithiummai ka makahiki 1970, i ka wā i hoʻomaka mua ai ka poʻe noiʻi e ʻimi i ka hiki o ka lithium ma ke ʻano he kumu nui i loko o nā pākaukau rechargeable. ʻO ia ka manawa i ʻike ai ka poʻe ʻepekema i nā waiwai kūʻokoʻa o ka lithium, me ka nui o ka ikehu kiʻekiʻe a me ke ʻano māmā, i mea kūpono no nā mea uila uila. Ua hoʻokumu kēia ʻike i ke kumu no ka hoʻomohala ʻana i nā pā lithium-ion, e hoʻomau i ka mana o ka mākeke uila uila no nā makahiki e hiki mai ana.
I ka makahiki 1979, ua hana ʻo John Goodenough a me kāna hui i kahi holomua a hoʻomohala i ka pākaukau lithium-ion rechargeable mua. ʻO kēia hana paionia i hoʻokumu i ke kumu no ka hoʻolaha ʻana i nā pā lithium-ion, e ulu wikiwiki ana ma muli o kā lākou hana ʻoi aku ka maikaʻi a me ka lōʻihi o ka lawelawe ʻana i hoʻohālikelike ʻia me nā pākaukau lead-acid a me nickel-cadmium.
Ma nā 1980s a me 1990s, nui nā noiʻi a me nā hana hoʻomohala i kālele ʻia i ka hoʻomaikaʻi ʻana i ka hana a me ka palekana o nā pā lithium. ʻO kekahi o nā paʻakikī koʻikoʻi ʻo ka loaʻa ʻana o kahi electrolyte paʻa e hiki ke kū i ka nui o ka ikehu kiʻekiʻe o ka lithium me ka ʻole o ka pale ʻana i ka palekana. Ua alakaʻi kēia i ka hoʻomohala ʻana i nā ʻano hana electrolyte like ʻole a me nā ʻōnaehana hoʻokele pākaukau e hoʻomaikaʻi nui i ka hilinaʻi a me ka palekana o nā pā lithium-ion.
ʻO ka holomua o nā pā lithium
Ma nā 1980s a me 1990s, nui nā noiʻi a me nā hana hoʻomohala i kālele ʻia i ka hoʻomaikaʻi ʻana i ka hana a me ka palekana o nā pā lithium. ʻO kekahi o nā paʻakikī koʻikoʻi ʻo ka loaʻa ʻana o kahi electrolyte paʻa e hiki ke kū i ka nui o ka ikehu kiʻekiʻe o ka lithium me ka ʻole o ka pale ʻana i ka palekana. Ua alakaʻi kēia i ka hoʻomohala ʻana i nā ʻano hana electrolyte like ʻole a me nā ʻōnaehana hoʻokele pākaukau e hoʻomaikaʻi nui i ka hilinaʻi a me ka palekana o nā pā lithium-ion.
ʻO nā makahiki 2000 mua i hōʻailona i ka huli ʻana no nā pākahi lithium, me ka holomua o ka nanotechnology a me nā ʻepekema ʻenehana e hoʻoulu i ka hoʻomohala ʻana o ka lithium iron phosphate (LiFePO4) a me nā pākahi lithium polymer. Hāʻawi kēia mau mea kemika pākaukau hou i ka ikehu kiʻekiʻe, ka hiki ke hoʻopiʻi wikiwiki a me nā hiʻohiʻona palekana i hoʻonui ʻia, e hoʻonui hou i ka hoʻohana ʻana i nā pā lithium i nā ʻāpana automotive, aerospace a me ka ikehu hou.
ʻO ka wā e hiki mai ana o nā pākahi lithium
ʻO ka hoʻolaha nui ʻana o nā kaʻa uila (EVs) a me ka ulu nui ʻana o ka noi no ka mālama ʻana i ka ikehu ua alakaʻi i ka hoʻomohala ʻana o ka hana kiʻekiʻe.nā pākahi lithium. I kēia mau makahiki i hala iho nei, ua hoʻomaikaʻi hou ka holomua nui o ka ʻenehana pākaukau e like me nā electrolytes paʻa a me nā anodes silicon i ka nui o ka ikehu a me ke ola pōʻai o nā pā lithium, e hoʻolilo iā lākou i koho kūpono no ka mālama ʻana i ka ikehu nui a me ka paʻa o ka grid.
Hōʻike ka mōʻaukala o nā pākahi lithium i ka ʻimi mau ʻana i ka hana hou a me ka mana hoʻololi o ka ʻenehana. I kēia lā, ʻo nā pākahi lithium kahi pōhaku kihi o ka hoʻololi ʻana o ka ikehu maʻemaʻe, e hiki ai i ka hoʻohana ākea ʻana i nā kaʻa uila a me ka hoʻohui ʻana i ka ikehu hou. I ka ʻimi ʻana o ka honua e hōʻemi i kona hilinaʻi ʻana i nā wahie mōʻalihaku a me ka hakakā ʻana i ka hoʻololi ʻana i ke aniau, e pāʻani nui nā pākaukau lithium i ka hana ʻana i ka wā e hiki mai ana a haʻahaʻa-carbon.
Ka hopena
I ka hōʻuluʻulu ʻana, ka moʻolelo hoʻomohala onā pākahi lithiumhe huakaʻi kupaianaha o ka ʻike ʻepekema, ka ʻenehana hou, a me ka hoʻololi ʻoihana. Mai ko lākou mau lā mua ma ke ʻano he ʻimi ʻimi noiʻi a hiki i ko lākou kūlana i kēia manawa ma ke ʻano he mau mea mālama mālama ikehu, ua hele lōʻihi nā pā lithium i ka mana o ka honua hou. Ke hoʻomau nei mākou i ka wehe ʻana i ka mana piha o nā pā lithium, e hoʻomaka mākou i kahi au hou o ka mālama ʻana i ka ikehu maʻemaʻe, hilinaʻi a hoʻomau e hoʻohālikelike i ka wā e hiki mai ana o kā mākou honua.
Inā he mau nīnau kāu a makemake paha e aʻo hou aku, e ʻoluʻolu e ʻoluʻolue kikoo mai ia makou.
