E toru ngā hiahia nui o te pākahiko rokiroki pūngao, ko te haumaru te mea tino nui
Ko te rokiroki pūngao hikohiko te momo rokiroki pūngao matua i roto i te pūnaha hiko o te heke mai, ko te pākahiko me te PCS te uara teitei rawa atu me ngā arai i roto i te mekameka ahumahi, ko te tono matua kei roto i te haumaru teitei, te roa o te ora me te utu iti. I roto i aua mea, ko te haumaru te mea nui. I kī ētahi tohunga ahumahi, kei te tere te whanaketanga o te tipu hiko rokiroki pūngao hikohiko, engari ko te take haumaru te aukati o tana whanaketanga nui, kua tangi te whakaoho i te pahūtanga o te tipu hiko rokiroki pūngao o Beijing me te kaupapa rokiroki pūngao Tesla Ahitereiria mō te umanga rokiroki pūngao.
Hei whakatutuki i tēnei, ko ngā Whakaaro Arataki mō te Whakateretere i te Whakawhanaketanga o te Rokiroki Pūngao Hou e whakatairanga ana i te whakatūnga o ngā paerewa hangarau haumaru me te pūnaha whakahaere, te whakapakari i te whakahaere haumaru ahi, me te piri tonu ki te kaupapa matua o te haumaru; te haumaru teitei, te utu iti, te pono teitei, te roa o te ora me ētahi atu āhuatanga o te ahunga whakamua roa; te whakapakari i te haumaru o te rangahau hangarau rokiroki pūngao hikohiko me ētahi atu. Ko te Komihana Whakawhanake me te Whakahoutanga ā-Motu, te Poari Pūngao ā-Motu ki te whakarite i te tuhi o te "Ngā Mahi Wā poto mō te Whakahaere Haumaru o ngā Teihana Rokiroki Pūngao Hikohiko (Tauira)", kua tae atu hoki ki te hapori i te 24 o Ākuhata ki te kōrero ki te marea, hei whakapakari i te whakahaere haumaru rokiroki pūngao.
Ngā āhuatanga matua o te pākahiko haumaru teitei, roa te ora, me te uara o te nickel-metal hydride
E whakaatu ana ngā raraunga a te Rōpū Ahumahi Pūhiko o Haina he tino haumaru te hiko nikara-whakarewa hauwai, he roa te ora huringa, he porowhita nikara tōna hiko pai, ā, he koranu rokiroki hauwai te rauemi hohe o te hiko kino, he rauemi pumau, he pai ngā āhuatanga ātete mura o te hiko wai, kāore e pahū, e mura rānei, ko te kaha o te monomer pākahiko tae atu ki te 140wh/kg; ko te ora huringa tae atu ki te 3,000, he papaku te huringa āhua utu me te tuku tae atu ki te 10,000 wā, neke atu rānei; ka taea te whakamahi mō te neke atu i te 10,000 wā; ka taea te whakamahi mō te neke atu i te 10,000 wā. Neke atu i te 10,000 wā; ka taea te pupuri i te tere utu me te tuku teitei i roto i te taiao -40°C ~ 60°C. Neke atu i te 18 miriona ngā hokonga motuka Toyota HEV puta noa i te ao, ā, he maha ngā pākahiko nikara-whakarewa hauwai kei roto, kāore anō kia puta he take kotahi o ngā aituā tahunga pākahiko, kua manatokohia te haumaru teitei o te pākahiko.
Heoi anō, ko te utu me te tukunga o te pākahiko te hurihanga o te pūngao matū me te pūngao hiko, he nui te pānga o te pāmahana ki te tauhohenga matū. Ko te nuinga o ngā teihana hiko rokiroki pūngao kei waho, ko te nuinga o ngā momo pākahiko ka pāngia e te taiao me te pāmahana, ka whakawhāiti i te wāhi o ngā teihana hiko, ka ngoikore hoki te mahi rokiroki pūngao. Ko ngā pākahiko nikara-whakarewa wairākau i ngā pāmahana tino iti me ngā pāmahana teitei he tino pai te whai huatanga o te utu me te tukunga, kia ngāwari ake ai, kia watea ai te wāhi o te teihana hiko rokiroki pūngao, kia pai ake ai te mahi whānui, kua waiho hei wāhi mōna ki te whakataetae o ngā huarahi hangarau pākahiko rerekē "ngā tohu tāpiri".
Ina hoki, ko ngā pākahiko nikara-whakarewa i roto i te mākete rokiroki pūngao he tauira tuatahi. I te tau 2020, i whakangaohia e te kamupene rokiroki pūngao Nilar te 47 miriona euros e te European Investment Bank. E mārama ana kei te arotahi a Nilar ki te whakaurunga me te rokiroki whakaputa hiko whakahou, te hiko tūmatanui me ngā tono utu waka hiko, ko te haumitanga hei whakatairanga i te whakaurunga o te kamupene ki roto i te pākahiko mō ngā pūnaha mākete kāinga, arumoni me te ahumahi me te whatunga-tauine, hanganga rānei. E ai ki a Frontiers in Polymer Science, kua whakawhanakehia e te tīma a Ahorangi Yi Cui i Te Whare Wānanga o Stanford he pākahiko nikara-whakarewa (Ni-MH) mō ngā tono rokiroki me te pūngao whakahou nui, me ngā painga o te roa o te ratonga, kāore he mōrearea o te ahi, te rere wera rānei, kāore he hiahia mō te tiaki auau, he pai te whanonga pāmahana iti, me te utu iti. Ka hangaia e te tīma a Cui he waeine whakamātautau me te kaha rokiroki o te 2 megawatts i te tau 2021, ā, kei te whakamahere kia whakawhānui ake i tōna kaha ki te 20 ngā wā o taua nui i te tau 2022.
