Mā tētahi momo pākahiko hou i hangaia mai i ngā pūmua e kawe ana i te hiko—he kirihou te nuinga—ka āwhina i te whakaiti i te utu me te roa o te rokiroki pūngao i runga i te whatunga hiko, ka taea ai te whakamahi nui ake i te hiko whakahou.
Ko ngā pākahiko, i hangaia e te kamupene hou o BostonPolyJoule, ka taea te tuku i tētahi atu huarahi iti ake te utu, he roa ake hoki te ora hei whakakapi i ngā pākahiko lithium-ion mō te penapena hiko mai i ngā pūtake hiko wā poto pēnei i te hau me te rā.
Kei te whakaatu te kamupene i ana hua tuatahi. Neke atu i te 18,000 ngā pūtau kua hangaia e PolyJoule, ā, kua tāutahia he kaupapa whakamātautau iti mā te whakamahi i ngā rauemi iti te utu, e wātea whānuitia ana.
Ko ngā pūhui kawe hiko e whakamahia ana e PolyJoule i roto i ōna irahiko pākahiko ka whakakapi i te lithium me te mata e kitea ana i roto i ngā pākahiko. Mā te whakamahi i ngā rauemi ka taea te hanga ngāwari me ngā matū ahumahi e wātea ana, ka karohia e PolyJoule tete pēhitanga o te tukute anga atu ki ngā rauemi pēnei i te lithium.
I tīmatahia a PolyJoule e ngā ahorangi o MIT, a Tim Swager rāua ko Ian Hunter, ā, i kitea e rāua he pai ngā pūmua kawe hiko mō te penapena pūngao. Ka taea e rātou te pupuri i te utu mō te wā roa, ā, ka tere te utu. He pai hoki te mahi, arā, ka penapenahia e rātou te nuinga o te hiko e rere ana ki roto. Nā te mea he kirihou, he iti te utu o ngā rauemi ki te hanga, ā, he pakari hoki, ka mau ki te pupuhi me te whakawhāiti e puta ana i roto i te pākahiko i a ia e utu ana, e tuku ana hoki.
Ko tētahi ngoikoretanga nui kote matotoru o te pūngao"E rua ki te rima ngā wā te rahi o ngā pākahiko i te pūnaha lithium-ion o te kaha rite, nō reira i whakatau ai te kamupene he pai ake te hangarau mō ngā tono tūmau pēnei i te rokiroki whatunga i ngā mea hikohiko, ngā motuka rānei," te kī a te Tumu Whakarae o PolyJoule, a Eli Paster.
Engari, he rerekē ki ngā pākahiko lithium-ion e whakamahia ana mō taua kaupapa i nāianei, kāore ngā pūnaha a PolyJoule e hiahia ki ngā pūnaha whakahaere pāmahana hohe hei whakarite kia kore e wera rawa, e mura rānei, tāna tāpiri. "E hiahia ana mātou ki te hanga i tētahi pākahiko tino pakari, iti te utu, e haereere noa ana ki ngā wāhi katoa. Ka taea e koe te whakamahi ki ngā wāhi katoa, ā, kāore koe e manukanuka ki tēnā," te kī a Paster.
Tērā pea ka noho ko ngā pūmua kawe hiko hei kaitākaro nui i roto i te rokiroki whatunga, engari ko te tupu o tēnā ka whakawhirinaki pea ki te tere o te whakatairanga a te kamupene i tana hangarau, me te mea nui, ki te utu o ngā pākahiko, e ai ki a Susan Babinec, te kaiārahi o te kaupapa rokiroki pūngao i Argonne National Lab.
ētahirangahaue tohu ana ki te $20 mō ia kilowatt-haora o te rokiroki hei whāinga roa hei āwhina i a tātou ki te whakatutuki i te 100% o te whakamahinga pūngao whakahou. He tohu nui tēnei e kī ana ko ētahi atu huarahi kē atungā pākahiko rokiroki whatungae arotahi ana ki. E ai ki a Form Energy, e hanga ana i ngā pākahiko hau-rino, ka taea e ia te whakatutuki i taua whāinga i roto i ngā tekau tau e haere ake nei.
Kāore pea a PolyJoule e whiwhi utuhe iti rawa, e whakaae ana a Paster. Kei te whai whāinga ia i tēnei wā ki te $65 mō ia kilowatt-haora o te rokiroki mō āna pūnaha, me te whakaaro pea ka pai ngā kaihoko ahumahi me ngā ratonga hiko ki te utu i taua utu nā te mea me roa ake te ora o ngā hua, ā, he māmā ake, he iti ake hoki te utu tiaki.
Tae noa ki tēnei wā, e ai ki a Paster, kua arotahi te kamupene ki te hanga i tētahi hangarau he māmā noa te hanga. Ka whakamahia he matū hanga wai, ā, ka whakamahia hoki ngā mīhini e wātea ana i te hokohoko hei huihui i ana pūtau pākahiko, nō reira kāore e hiahiatia ngā tikanga motuhake e hiahiatia ana i ētahi wā i roto i te hanga pākahiko.
Kāore anō kia mārama he aha te matū o te pākahiko ka toa i roto i te rokiroki whatunga. Engari nā ngā kirihou a PolyJoule kua puta mai he kōwhiringa hou.
