Kupu Whakataki:
E toru ngā wāhanga matua o ngā pākahiko: ngā pākahiko matū, ngā pākahiko ā-tinana, me ngā pākahiko koiora. Ko ngā pākahiko matū te mea e whakamahia whānuitia ana i roto i ngā waka hiko.
Pūhiko matū: He taputapu te pūhiko matū e huri ana i te pūngao matū hei pūngao hiko mā roto i ngā tauhohenga matū. Kei roto ko ngā irahiko me ngā irahiko pai, kino hoki.
Pūhiko ā-tinana: Ka hurihia e te pūhiko ā-tinana te pūngao ā-tinana (pērā i te pūngao o te rā me te pūngao ā-pūkaha) hei pūngao hiko mā roto i ngā huringa ā-tinana.
Te whakarōpūtanga o te pākahiko matū: Mai i te tirohanga hanganga, ka taea te wehewehe kia rua ngā wāhanga: ngā pākahiko rokiroki (tae atu ki ngā pākahiko tuatahi me ngā pākahiko tuarua) me ngā pūtau wahie. Ngā pākahiko tuatahi: ka taea te whakamahi kotahi anake, kāore e taea te whakakore i te rauemi hohe, he iti te tukunga-ake, he nui te ātete ā-roto, ā, he teitei te kaha motuhake o te papatipu me te kaha motuhake o te rōrahi.
Ngā pākahiko tuarua: ka taea te utu me te tuku i ngā wā maha, ka taea te huri i te rauemi hohe, ā, he whānuitia te whakamahinga i roto i ngā momo taputapu utu. Ko te nuinga o ngā tauira kei te mākete e whakamahi ana i ngā pākahiko tuarua ka taea te utu anō hei taraiwa i te waka. Ka wehea ngā pākahiko tuarua ki ngā pākahiko waikawa-mata, ngā pākahiko nikara-karamiuma, ngā pākahiko nikara-waikawa me ngā pākahiko riitiuma e ai ki ngā rauemi hiko pai rerekē. I tēnei wā, ko ngā kamupene motuka kei te mākete e whakamahi ana i ngā pākahiko riitiuma, ā, he iti noa iho e whakamahi ana i ngā pākahiko nikara-waikawa.
Te whakamāramatanga o te pākahiko lithium
Ko te pākahiko lithium he pākahiko e whakamahi ana i te konganuku lithium, i te koranu lithium rānei hei rauemi hiko pai, kino rānei, hei otinga hiko kore-wai hoki.
Ko te tukanga utu me te tukunga o te pākahiko lithium e whakawhirinaki ana ki te nekehanga o ngā katote lithium (Li+) i waenga i ngā irahiko pai me ngā irahiko kino. I te wā e utu ana, ka tangohia ngā katote lithium mai i te irahiko pai ka whakauruhia ki roto i te irahiko kino mā roto i te electrolyte, ā, kei roto te irahiko kino i te āhua whai-lithium; ko te ritenga kē te pono i te wā e tukunga ana.
Te kaupapa hikohiko o te pākahiko lithium-ion
Tātai tauhohenga hiko pai: LiCoO2 → Li1-xCoO2 + xLi+ + xe-
Tātai tauhohenga hiko tōraro: C + xLi+ + xe- → CLix
He nui te kaha o ngā pākahiko lithium-ion, he roa te ora, ā, he iti te tere tukunga-ake, ā, e whakamahia whānuitia ana i roto i ngā waea pūkoro, ngā pona me ngā waka hiko.
Ko ngā mara tono o ngā pākahiko lithium-ion e wehea ana ki te mana hiko me te kore-mana. Ko ngā mara tono o ngā pākahiko lithium-ion ko ngā waka hiko, ngā taputapu hiko, me ētahi atu; ko ngā mara kore-mana ko ngā hiko kaihoko me ngā mara rokiroki pūngao, me ētahi atu.
Te hanganga me te whakarōpūtanga o ngā pākahiko lithium
Ko ngā pākahiko lithium-ion te nuinga o te wā he mea tito mai i ngā wāhanga e whā: ngā rauemi irahiko pai, ngā rauemi irahiko kino, ngā irahiko me ngā wehewehe pākahiko. Ko ngā rauemi irahiko kino te nuinga o te pānga ki te pai o te tīmatanga me te mahi huringa o ngā pākahiko lithium-ion. E rua ngā wāhanga matua o ngā irahiko kino pākahiko lithium: ngā rauemi waro me ngā rauemi kore-waro. Ko te tono tino aro ki te mākete ko te rauemi irahiko kino karāhe i roto i ngā rauemi waro, kei roto i ēnei ko te karāhe horihori me te karāhe taiao he tono ahumahi nui. Ko ngā irahiko kino e ahu mai ana i te silicon te kaupapa matua o te rangahau a ngā kaihanga irahiko kino nui, ā, ko tētahi o ngā rauemi irahiko kino hou ka whakamahia pea i runga i te tauine nui a muri ake nei.
E ai ki ngā rauemi irahiko pai, ka whakarōpūtia ngā pākahiko lithium-ion ki ngā pākahiko lithium cobalt oxide, ngā pākahiko lithium rino phosphate, ngā pākahiko toru, me ētahi atu;
E ai ki te āhua o te hua, ka wehea ēnei ki ngā pākahiko tapawhā, ngā pākahiko porotaka me ngā pākahiko pōkai-ngohengohe;
E ai ki ngā āhuatanga tono, ka taea te wehewehe i ēnei ki ngā hikohiko kaihoko, te rokiroki pūngao me ngā pākahiko hiko. I roto i ēnei, ko ngā pākahiko lithium kaihoko e whakamahia ana i roto i ngā hua 3C; ko ngā pākahiko rokiroki pūngao e whakamahia ana i roto i te rokiroki pūngao o te whare me te rokiroki pūngao pūnaha hiko motuhake tohatoha pēnei i te pūngao o te rā me te whakaputa hiko hau; ko ngā pākahiko hiko e whakamahia ana i roto i ngā waka hiko, ngā taputapu hiko me ngā waka hiko hou.
