Hangarau Whakahaere Wera mō ngā Waka Hiko Parakore

Ehara i te mea ka whakarite noa te pūnaha whakahaere wera o ngā waka hiko parakore i tētahi taiao taraiwa whakamarie mō te taraiwa, engari ka whakahaere anō hoki i te pāmahana, te haumākū, te pāmahana o te hau, me ērā atu mea o roto. Ko te nuinga o te wā ka whakahaere i te pāmahana o te pākahiko hiko. Ko te whakahaere pāmahana o te pākahiko hiko he whakarite i te haumaru o te waka hiko. He mea nui tēnei mō te whakahaere pai me te haumaru o ngā motuka.

He maha ngā tikanga whakamatao mō ngā pākahiko hiko, ka taea te wehewehe i ēnei ki te whakamatao hau, te whakamatao wai, te whakamatao totohu wera, te whakamatao rauemi huringa āhuahanga me te whakamatao paipa wera.

Ka pāngia te mahi a ngā pākahiko lithium-ion e te pāmahana teitei rawa, iti rawa rānei, engari he rerekē ngā pānga o ngā pāmahana rerekē ki te hanganga o roto o te pākahiko me ngā tauhohenga matū katote.

I ngā pāmahana iti, he iti te kawe irahiko o te irahiko i te wā e utu ana, e tuku ana, ā, he teitei ngā ārai i te atanga irahiko pai/irahiko me te atanga irahiko kino/irahiko, e pā ana ki te ārai whakawhiti utu i runga i ngā mata irahiko pai me kino, me te horapa o ngā iona lithium i roto i te irahiko kino. Ka pāngia ngā tohu matua pēnei i te tere tukunga o te pākahiko me te pai o te utu me te tukunga. I ngā pāmahana iti, ka totoka tetahi wāhanga o te whakarewa i roto i te irahiko o te pākahiko, ka uaua ai te heke o ngā iona lithium. I te hekenga o te pāmahana, ka piki tonu te ārai tauhohenga hiko o te tote irahiko, ā, ka heke tonu hoki te pūmau wehenga o ōna iona. Ka tino pāngia ēnei āhuatanga e te tere nekehanga o ngā iona i roto i te irahiko ka whakaiti i te tere tauhohenga hiko; ā, i te wā e utu ana te pākahiko i te pāmahana iti, ka tīmata te uaua o te hekenga o ngā iona lithium ki te whakaheke i ngā iona lithium ki ngā dendrite irahiko whakarewa, ka hua ake te pirau o te irahiko me te pikinga o te porotiti kukū. Heoi anō, ka taea e ngā koki koi o tēnei dendrite konganuku lithium te wero i te wehewehe o roto o te pākahiko, ka puta he ara iahiko poto i roto i te pākahiko, ka puta hoki he aituā haumaru.

E kore te pāmahana teitei e whakapakeke i te whakarewa electrolyte, e kore hoki e whakaiti i te tere horapa o ngā katote tote electrolyte; engari, ka whakanui ake te pāmahana teitei i te mahi tauhohenga electrochemical o te rauemi, ka whakanui ake i te tere horapa katote, ka tere ake te hekenga o ngā katote lithium, nō reira, i roto i tētahi tikanga, ka āwhina ngā pāmahana teitei ki te whakapai ake i te mahi utu me te tukunga o ngā pākahiko lithium-ion. Heoi, ina tino teitei te pāmahana, ka tere ake te tauhohenga pirau o te kiriata SEI, te tauhohenga i waenga i te waro kua whakauruhia ki te lithium me te electrolyte, te tauhohenga i waenga i te waro kua whakauruhia ki te lithium me te piripiri, te tauhohenga pirau o te electrolyte me te tauhohenga pirau o te rauemi cathode, ā, ka pā kino ki te roa o te mahi me te mahi a te pākahiko. Te mahi whakamahinga. Tata kore e taea te huri i ngā tauhohenga o runga ake nei. Ina tere ake te tere tauhohenga, ka tere te heke o ngā rauemi e wātea ana mō ngā tauhohenga electrochemical hurihuri i roto i te pākahiko, ka heke te mahi a te pākahiko i roto i te wā poto. Ā, ina piki tonu te pāmahana o te pākahiko ki tua atu i te pāmahana haumaru o te pākahiko, ka puta noa te tauhohenga pirau o te electrolyte me ngā electrodes i roto i te pākahiko, ka puta he nui te wera i roto i te wā poto rawa, arā, ka puta he pakaru wera o te pākahiko, ka meinga kia tino whakangaromia te pākahiko. I roto i te wāhi iti o te pouaka pākahiko, he uaua ki te memeha te wera i roto i te wā, ā, ka tere te kohikohi o te wera i roto i te wā poto. He tino tūponotanga ka horapa tere te pakaru wera o te pākahiko, ka meinga te kete pākahiko kia paowa, kia mura noa, kia pahū rānei.
