I roto i te tukanga whakaputa pākahiko lithium-ion, ko te tukanga paninga, hei hononga matua, ka pā tika ki te mahi me te haumaru o ngā pākahiko. Ko te pumau o te papa whakahaere nekehanga o te mīhini paninga pākahiko lithium he mea nui ki te tika o te paninga. Ko te karāneti me te rino maka, hei rauemi papa e whakamahia whānuitia ana, kua aro nui te aro ki te rerekētanga o te pumau o ō rātou āhua. Ka tātarihia hohonutia e tēnei tuhinga te whakapainga nui o te pumau o te āhua o te karāneti ki te rino maka i runga i te papa whakahaere nekehanga o ngā mīhini paninga pākahiko lithium mā roto i ngā āhuatanga rauemi, ngā raraunga whakamātautau me ngā take tono mahi.
Ko ngā āhuatanga rauemi te pūtake o te pumau
I mua, i whakamahia whānuitia te rino maka, hei rauemi ahumahi tuku iho, i roto i te ao o ngā papa whakahaere nekehanga nā te mea he pai te mahi whakarewa me ngā painga utu. Heoi, he hapa ā-roto anō hoki ngā rauemi rino maka. He nui te karāpeti maramara kei roto i tōna hanganga o roto, he rite ki ngā kapiti o roto, ā, ka whakaiti i te pakari whānui o te rauemi. I taua wā, he teitei te tauwehenga o te whakawhānui wera o te rino maka, tata ki te 10-12 ×10⁻⁶/℃. I raro i te kohikohinga o te wera i puta mai i te whakamahinga roa o te paninga pākahiko lithium, ka ngāwari ki te whakarerekē i te wera. Hei tāpiri, kei roto i te rino maka te ahotea whakarewa. I roto i te wā, ka puta he huringa kore e taea te huri i te rahi o te papa, ka pā ki te tika o te paninga.
He rauemi taiao te karāneti i hangaia mā roto i ngā tukanga whenua mō ngā rau miriona tau. He matotoru, he ōrite te hanganga o roto o te karaihe, ā, he tino pumau tōna. Ko te tauwehenga whānui raina o te karāneti he 0.5-8×10⁻⁶/℃ anake, arā, 1/2-1/3 o te rino maka, ā, he tino kore e pāngia e ngā huringa pāmahana. I taua wā, he mārō te kakano o te karāneti, ā, ko te kaha pēhi he 1,050-14,000 kirokaramu ia henimita tapawha. Ka taea e ia te ātete pai ki ngā pānga kaha o waho me ngā wiri, e whakarato ana i te turanga pakari me te pumau mō te papa whakahaere nekehanga. Kāore he ahotea toenga i roto, ā, e kore e puta he huringa āhuahanga nā te tukunga ahotea, e whakarite ana i te pumau āhuahanga o te papa mai i te mauri o te rauemi.
Ka whakamanahia ngā rerekētanga mahi e ngā raraunga whakamātautau
Hei whakataurite ā-kanohi i ngā rerekētanga o te pumau o ngā āhuatanga i waenga i te karāneti me te rino maka, i whakahaerehia e te tīma rangahau tētahi whakamātautau motuhake. E rua ngā papa whakahaere nekehanga o te mīhini paninga pākahiko lithium o te whakatakotoranga kotahi i tīpakohia, he mea hanga ki te karāneti me te rino maka, ā, i whakamatautauria i raro i ngā āhuatanga taiao kotahi. I whakatauira te whakamātautau i te horopaki mahi tuturu o te mīhini paninga pākahiko lithium. Mā te whakahaere tonu i ngā taputapu, i aroturukitia ngā huringa rahi o te papa i ngā wā rerekē.
E whakaatu ana ngā hua whakamātautau, i muri i te mahi tonu mō ngā hāora 24, nā te wera i puta mai i te whakahaerenga o ngā taputapu, ka piki ake te pāmahana o te mata o te papa rino maka mā te 15℃, ā, ka piki ake te roa o te papa mā te 0.03mm. I raro i ngā āhuatanga ōrite, he iti noa te rerekētanga o te rahi o te papa karāhe, ā, he iti iho i te 0.005mm te whānuitanga o te rerekētanga o te rahi. I muri i te 1000 hāora o ngā whakamātautau tawhito mō te wā roa, nā te tukunga o te ahotea ā-roto me te kohikohinga o te whakarerekētanga wera, ka whānui ake te hapa papatahi o te papa rino maka mai i te 0.01mm tuatahi ki te 0.05mm. Ka puritia tonutia te hapa papatahi o te papa karāhe ki roto i te 0.015mm, ā, he mārama te painga o te pumau o te rahi.
Ngā whakatutukitanga whakamiharo i roto i ngā tono mahi
I roto i te hanga tuturu o tētahi umanga hanga pākahiko lithium nui, i whakamahia ngā papa whakahaere nekehanga rino maka i mua. I te pikinga ake o te wā mahi o ngā taputapu, ka heke haere te tika o te paninga, ka hua ake he matotoru paninga kāore i te ōrite, he ngoikore te hanganga o ngā pepa hiko pākahiko, me te tere hua hapa tae atu ki te 8%. Hei whakaoti i tēnei raruraru, i whakakapia e te umanga ngā papa whakahaere nekehanga o ētahi taputapu ki ngā rauemi karāhe.
I muri i te whakakapinga, kua tino pai ake te pumau o ngā āhuatanga o ngā taputapu. I roto i te huringa whakaputa e ono marama te roa, i mau tonu te hapa matotoru o te paninga i roto i te ±2μm e te mīhini paninga e whakamahi ana i te papa granite, ā, i tino heke te tere o te hua hapa ki raro iho i te 3%. I taua wā, nā te mea kāore e hiahiatia he whakatikatika me te tiaki tika auau mō ngā papa granite pērā i ngā papa rino maka, ka penapenahia e rātou he nui o ngā utu tiaki taputapu me te wā kore mahi a ngā umanga i ia tau, ā, ka piki ake te pai o te whakaputanga mā te neke atu i te 15%.
Hei whakamutunga, i roto i te whakamahinga o te papa whakahaere nekehanga o ngā mīhini paninga pākahiko lithium, ko te karāneti, me ōna āhuatanga rauemi tino pai, he nui ake te pai ake i te rino maka i runga i te pumau o te rahi. Ahakoa mai i te tirohanga o te āhua rauemi, o ngā raraunga whakamātautau, o ngā pānga tono mahi rānei, ka whakaratohia e te karāneti he taurangi pono mō te whakaputanga tino tika me te pumau o ngā tukanga paninga pākahiko lithium. Me te whakapai tonu i ngā whakaritenga kounga hua i roto i te umanga pākahiko lithium, ko ngā papa whakahaere nekehanga i hangaia ki te karāneti ka noho hei whiringa matua i roto i te umanga.
