ʻO nā pākahi Lithium-ion kahi ʻenehana kokoke i nā wahi āpau me kahi drawback koʻikoʻi: hopu lākou i ke ahi i kekahi manawa.
ʻO ke wikiō o nā poʻe holo moku a me nā poʻe kaʻa ma ka mokulele ʻo JetBlue e ninini nui ana i ka wai ma kā lākou ʻeke ʻeke i lilo i kumu hoʻohālike hou loa o nā hopohopo ākea e pili ana i nā pākaukau, hiki ke loaʻa i kēia manawa ma kahi kokoke i kēlā me kēia mea e pono ai ka mana lawe lima.I loko o nā makahiki he ʻumi i hala iho nei, ua hoʻonui ʻia nā poʻomanaʻo e pili ana i ke ahi pākaukau lithium-ion i hana ʻia e nā kaʻa uila, nā kaʻa uila a me nā kamepiula ma nā mokulele mokulele.
ʻO ka ulu ʻana o ka hopohopo lehulehu ua hoʻoikaika i ka poʻe noiʻi a puni ka honua e hana e hoʻomaikaʻi i ka palekana a me ka lōʻihi o nā pā lithium-ion.
Ke pahū nei ka hana hou ʻana o ka pākaukau i nā makahiki i hala iho nei, me ka poʻe noiʻi e hana ana i nā ʻōhua paʻa paʻa ma o ka hoʻololi ʻana i nā electrolytes wai flammable i nā pākahi lithium-ion maʻamau me nā mea electrolyte paʻa paʻa e like me nā gels nonflammable, nā aniani inorganic a me nā polymers paʻa.
ʻO ka noiʻi i paʻi ʻia i ka pule i hala ma ka puke moʻolelo Nature e hōʻike ana i kahi hana palekana hou e pale ai i ka hoʻokumu ʻia ʻana o ka lithium "dendrites," i hana ʻia i ka wā e wela ai nā pā lithium-ion ma muli o ka overcharging a hōʻino paha i ka hale dendritic.Hiki i nā Dendrites ke hoʻopōkole i nā pila a hoʻoulu i ke ahi pahū.
"ʻO kēlā me kēia haʻawina e hāʻawi iā mākou i ka hilinaʻi nui aʻe e hiki iā mākou ke hoʻoponopono i nā pilikia palekana a me ka laulā o nā kaʻa uila," i ʻōlelo ai ʻo Chongsheng Wang, ke kaukaʻi o ka ʻenekinia a me ka biomolecular engineering ma ke Kulanui o Maryland a me ke alakaʻi kumu o ka noiʻi.
ʻO ka hoʻomohala ʻana o Wang he hana koʻikoʻi i ka hoʻomaikaʻi ʻana i ka palekana o nā pā lithium-ion, wahi a Yuzhang Li, he loea kōkua o ka ʻenekinia kemika ma UCLA ʻaʻole i komo i ka noiʻi.
Ke hana nei ʻo Lee i kāna hana hou, e hana ana i kahi pākahi lithium metala hou aʻe e hiki ke mālama i nā manawa he 10 ʻoi aʻe ka ikaika ma mua o nā ʻāpana electrode graphite i nā ʻāpana lithium-ion kuʻuna.
I ka wā e pili ana i ka palekana kaʻa uila, ua ʻōlelo ʻo Lee ʻaʻole ʻino a maʻamau paha nā pā lithium-ion e like me ka manaʻo o ka lehulehu, a he mea koʻikoʻi ka hoʻomaopopo ʻana i nā protocol palekana pākaukau lithium-ion.
"He mau pilikia ko nā kaʻa uila a me nā kaʻa maʻamau," wahi āna."Akā, manaʻo wau ʻoi aku ka palekana o nā kaʻa uila no ka mea ʻaʻole ʻoe e noho ana ma luna o nā galani wai wela."
Ua hoʻohui ʻo Lee he mea nui ia e hana i nā hana pale e kūʻē i ka overcharging a i ʻole ma hope o kahi ulia kaʻa uila.
Ua ʻike ka poʻe noiʻi e aʻo ana i nā ahi pākaukau lithium-ion ma ka nonprofit Fire Research Foundation, ua like ke ahi o nā kaʻa uila i ka ikaika me nā ahi o nā kaʻa i hoʻohana ʻia i ka ʻaila maʻamau, akā ʻoi aku ka lōʻihi o ke ahi i nā kaʻa uila, pono ka wai e pio a ʻoi aku ka nui. e ʻā ana paha.hou.he mau hola ma hope o ka nalo ʻana o ka lapalapa ma muli o ke koena o ka ikehu i loko o ka pākaukau.
Ua ʻōlelo ʻo Victoria Hutchison, ka luna nui o ka papahana noiʻi o ka hoʻokumu, ʻo nā kaʻa uila he pilikia kūʻokoʻa i nā mea kuni ahi, nā mea pane mua a me nā mea hoʻokele ma muli o kā lākou mau pā lithium-ion.Akā ʻaʻole ia he manaʻo e makaʻu ka poʻe iā lākou, ua hoʻohui ʻo ia.
"Ke hoʻāʻo nei mākou e hoʻomaopopo i ke ʻano o ke ahi kaʻa uila a pehea ka maikaʻi e hakakā ai iā lākou," wahi a Hutcheson.“He ʻano hoʻonaʻauao.Ua loaʻa iā mākou nā kaʻa ʻenekini hoʻopau i loko no ka manawa lōʻihi i kēia manawa, ʻoi aku ka ʻike ʻole ʻia, akā pono mākou e aʻo pehea e hana pono ai i kēia mau hanana.
Hiki i nā hopohopo e pili ana i ke ahi kaʻa uila ke hoʻonui i nā kumukūʻai ʻinikua, wahi a Martti Simojoki, he loea pale pale ma ka International Union of Marine Insurance.Ua ʻōlelo ʻo ia ʻo ka hōʻoia ʻana i nā kaʻa uila e like me ka ukana i kēia manawa kekahi o nā laina liʻiliʻi loa o ka ʻoihana no ka poʻe insurers, hiki ke hoʻonui i ke kumukūʻai o ka ʻinikua no ka poʻe e ʻimi nei e lawe i nā kaʻa uila ma muli o ka manaʻo o ke ahi.
Akā ʻo kahi noiʻi a ka International Union of Marine Insurance, kahi hui waiwai ʻole e hōʻike ana i nā hui ʻinikua, ʻike ʻia ʻaʻole ʻoi aku ka pōʻino a i ʻole ka pilikia o nā kaʻa uila ma mua o nā kaʻa maʻamau.ʻO kaʻoiaʻiʻo,ʻaʻole i hōʻoiaʻiʻoʻia he ahi kaʻa kiʻekiʻe ma waho o ke kahakai Dutch i kēia kauwela i hanaʻia e kahi kaʻa uila,ʻoiai nā poʻomanaʻo e hōʻike ana i kahi'ē aʻe, wahi a Simojoki.
"Manaʻo wau ʻaʻole makemake ka poʻe e lawe i nā pilikia," i ʻōlelo ai ʻo ia."Inā kiʻekiʻe ka pilikia, ʻoi aku ka kiʻekiʻe o ke kumukūʻai.I ka hopena o ka lā, uku ka mea kūʻai aku. "
Hoʻoponopono (Nov. 7, 2023, 9:07 am ET): Ua kuhi hewa kekahi mana o kēia ʻatikala i ka inoa o ka mea kākau alakaʻi.ʻO Wang Chunsheng ʻo ia, ʻaʻole ʻo Chunsheng.
