Ko te wero he kaupapa matua nui ki te whakatau i te mahi, te maroke, me te roa o ngā pūnaha rīwha mā ia tono. Mai i ngā waka hiko ki ngā rama e taea ana te whakauru anuanu, he mea nui kia mōhio pēhea ka pā te takotoranga wero ki ngā taputapu penapena wairua kia pai ai te hoahoa me te whakahaerenga o te pūnaha. Ko te hononga i waenganui i te wero me te mahi a te rīwha e whai pānga ana ki ngā tikanga electrochemical mātāmua e āwhina ana i te maha, te hiko hiko, te maroke uta, me te ora o ēnei wae rīwha matua.

Me whakaeke ngā punaha whakapūmau rerekē i ngā tikanga taiao maha, nō reira ko te whakahaere i te wera he whakaaro matua mō te hoahoa kōpae riipoka. Ahakoa ka tūmōhi ki te makariri tino, ki te wera hoki, e āhua ngā wero motuhake ka taea e ngā punaha nei te pā ki ō rātou āhuatanga mahi. Ka taea e ngā inijiniara me ngā kaihoahoa punaha te whakamahi i ngā rautaki whakahaere wera e hāngai ana, me te whiriwhiri i ngā hangarau riipoka e hāngai ana mō ngā whakamahinga motuhake mā te mārama ki ēnei pānga wera.

Ngā Pānga Matua o te Wera ki te Kimikimekameka Riipoka

Ngā Tere Tākimokimo o te Kimikimekameka Riipoka

Ko ngā whakaururanga electrochemical kei roto i ngā wae rite o te pūhiko he tikanga e noho pā ki te temparatū tino ana, ā, ka arataki ki ngā mātai mōhio kua whakaturia pai. Ake ake te temparatū, ka huritaua ngā tere o ngā whakauru nā te nekenga ake o ngā iona me te itinga o te herehere o roto. Ka taea e tēnei huritao te whakanui i ngā pūkenga tuku hiko engari ka taea anō hoki te whakapiki i ngā ururanga taha kore e hua ai te whakarohe o te mōhio i te wā.

Ka pakaru tēnei momo whakaururanga electrochemical i ngā temparatū iti, ka hua ai te iti ake o te mōhio me te hiko ka puta mai. Ka piki ake te kīato o ngā wehenga electrolyte i ngā āhuatanga makariri, ka whakapōaitia te nekenga o ngā iona, ā, ka hua ai tētahi herehere o roto e teitei ake. Ko ēnei āhuatanga e āhua tino kitea ana i ngā matū e pā ana ki te lithium, nā te wāhi e herenga ai te papanga electrolyte taupiri he wāhi uaua ake i ngā āhuatanga makariri.

Ko ngā panonitanga o te wera hoki e whai pānga ana ki te mōhini taurite o ngā wae rere, me te nuinga o ngā kimikime e whakaatu ana i ngā panonitanga o te mōhini e 2-3 miri-mōhini pea ia kelvinia. Me mātua whakauru tēnei here ki te hoahoa punaha whakahaere rere kia tino pono ai te whakataunga o te āhuatanga-tauā i roto i ngā tauwae wera.
