Kupu Whakataki:
Āe, tērā pea ka hurihia rawatia e tēnei mea hou ngā ture o te ao i roto i te umanga pūngao hou o te ao! I te 12 o Pēpuere, 2025, i whakaputa te hautaka rongonui o te ao, a Nature, i tētahi putanga hou. Nā te tīma o Peng Huisheng/Gao Yue o Te Whare Wānanga o Fudan i Haina i hanga he mea hou.hangarau "whakaora" pākahiko lithium, e takahi ana i ngā mātāpono hoahoa tuku iho o ngā pākahiko lithium mō ngā tau neke atu i te 30, ka taea te whakaroa i te roa o te pākahiko neke atu i te 10 ngā wā! Kei te pupuri tonu te pākahiko lithium rino phosphate noa i te 96% o tōna kaha i muri i te 11,818 huringa utu me te tukunga! E mōhio ana koe, ko ngā pākahiko lithium kei te mākete i tēnei wā e whakamahia ana mō te 1000-2000 ngā wā.
He aha te tikanga o tēnei? I mua, me whakakapi te pākahiko o te Tesla i ia 6-8 tau, engari ināianei ka taea te taraiwa mō te 60 tau me te kore e hiahiatia te whakakapi! Ka taea te utu me te whakakore i tō iPhone i ngā wā 10,000 me te kore e ngaro te hiko!
Ko te whakaaweawe mō te hangarau whakatika pākahiko i ahu mai i te rongoā tangata
Nō hea te whānautanga o tēnei kitenga whakamiharo?
"Pērā i te rongoā i ngā mate tangata, ka arotahi mātou ki te whakatika i ngā take matua o ngā pākahiko me te tiaki i ō rātou wāhanga hauora," te whakamārama a Gao Yue, he kairangahau i Te Whare Wānanga o Fudan.
I te tīmatanga, ko te take matua o te "pakeketanga" o ngā pākahiko lithium ko te ngaronga o ngā ion lithium. Pērā i te korenga o tētahi matūkai i roto i te tinana tangata ka arahi ki te mate, ka taea hoki e ngā pākahiko te heke te mahi nā te kore kai pai. Ko te whakaaro hou o te tīma ko: Ka taea e tātou te whakakī anō i ngā ion lithium ngaro i roto i te pākahiko, pērā i te werohanga ki tētahi tūroro?
Ka āwhina te AI ki te wawahi i ngā hangarau taurite pākahiko matua
Heoi, ehara i te mea ngāwari te kimi i te "werohanga" e tika ana. Me tutuki i tēnei ngota kawe ngā whakaritenga ā-tinana me te matū tino pakari i te wā kotahi:
- Kia tika te ngohe hikohiko me te awhe ngaohiko pirau.
- Te wairewatanga e tika ana i roto i te electrolyte.
- He tino pai te pumau o te hau, me te pumau matū.
- Te waikawa, te kawakore, me te tere o te tauhohenga e tika ana.
- Me noho haumaru, me te kore he kino o ngā hua pirau.
- Ko te mea nui, me iti te utu, ā, me ngāwari hoki te whakanui ake i te hanga.
Ka kitea e te matauranga horihori ngā rauemi matua
Nā te korenga o tētahi tauira i whai ake, ka tahuri te tīma rangahau ki te mātauranga horihori. I mamatihia e rātou ngā āhuatanga ngota ngota, ā, i whakamahia te ako mīhini hei rapu whakautu mai i te nui o ngā raraunga matū waro, matū hiko me te hangarau rauemi.
I hua te mahi uaua! Whai muri i ngā tau e whā o te mahi uaua, ka kitea e rātou te otinga tino pai: CF3SO2Li (lithium trifluoromethanesulfonate). He rite tēnei ngota ki tētahi kaikawe iti, e kawe ana i ngā irahiko lithium i tētahi pito, ā, ka tukuna haumarutia hei hau i tētahi pito i muri i te otinga o te kawe.
He tino ohorere ngā hua o te whakamātautau!
I roto i te whakamātautau, ko te pākahiko i whiwhi i tēnei "maimoatanga tika" i mau tonu te mahi tata ki te taumata wheketere ahakoa i muri i te 12000 ki te 60000 huringa utu me te tukunga. Ehara i te mea ka roa ake te ora o te pākahiko, engari ka whakaratohia hoki he otinga hangarau whai hua hei whakaoti rapanga o te parahanga pākahiko nui.
Heoi anō, he mea whakahihiri ake te whakatuwheratanga o ngā huarahi hou e tēnei hangarau:
I whakatinanahia he pūnaha pākahiko katote kore-litium me te ngaohiko o te 3.0V me te mātotoru pūngao tae atu ki te 1192 Wh/kg.
I whakawhanake i tētahi pākahiko putea katote polyacrylonitrile kua whakawhāitihia ki te whanariki waro me te mātotoru pūngao o te 388 Wh/kg.
Pānga Hurihuri
Ka tino hurihia e tēnei putanga hou ngā ture o te kēmu i roto i te umanga pūngao hou:
Ka tino whakaitihia te utu mō te whakamahi i ngā waka hiko, ka tino whakaitihia te parahanga taiao e puta mai ana i te tango pākahiko, ā, ka whakatuwherahia ngā whakaaro hou mō te hoahoa i ngā pākahiko hou; ko te mea tino whakahihiri ko te utu nui o tēnei hangarau - e tika ana kia iti iho i te 10% o te utu pākahiko katoa, ko te tikanga he kaha pea mō te whakamahinga arumoni nui!
E ai ki te kairangahau a Gao Yue: Ahakoa he whakaroa i te ora o te pākahiko, he ārai rānei i te whakarērea nui me te parahanga taiao, ka whakaratohia e tēnei "maimoatanga tika" he otinga hangarau whaihua. Ehara i te mea ko tēnei rangahau anake e whakaatu ana i te kaha auaha o Haina i roto i te ao o te pūngao hou, engari e tohu ana hoki i te taenga mai o tētahi wā hou. I roto i ngā rā kei te heke mai, ka noho pea te "manukanuka pākahiko" hei hītori. Kia titiro whakamua tātou ki te hokohoko o tēnei hangarau auaha i te wā e taea ai!
