Ka pāngia ngā pākahiko totoka e te makariri?

te pānga o te makariri ki ngā pākahiko totokame ngā mahi e mahia ana mōna:

He aha te wero o te makariri

1. Te kawe irahiko iti iho

   • Ka whakawhirinaki ngā irahiko totoka (ngā uku, ngā whanariki, ngā pūmua) ki ngā katote lithium e peke ana i roto i ngā hanganga tioata, pūmua rānei.

   • I ngā pāmahana iti, ka puhoi haere tēnei pekepeke, nō reiraka piki ake te ātete ā-rotome ngā hekenga o te tuku hiko.

2. Ngā raruraru atanga

   • I roto i tētahi pākahiko āhua-totoka, he mea tino nui te pānga i waenga i te electrolyte totoka me ngā irahiko.

   • Ka taea e ngā pāmahana makariri te whakaiti i ngā rauemi i ngā tere rerekē, ka hangangā āputa itii ngā atanga → ka kino ake te rere o te katote.

3. Te uaua o te utu

   • Pērā i ngā pākahiko lithium-ion wai, ka mōrearea te utu i ngā pāmahana tino itiwhakakikoruatia ki te lithium(te hanganga o te konukōre konukōre ki runga i te anode).

   • I te āhua totoka, ka nui ake te kino o tēnei mea nā te mea ka taea e ngā dendrite (ngā putunga lithium rite ki te ngira) te pakaru i te electrolyte totoka.

Ki te whakataurite ki te lithium-ion noa

• Ion-litiuma electrolyte waiMā te matao ka matotoru ake te wai (ka iti ake te kawe hiko), ka whakaitihia te whānuitanga me te tere o te utu.

• Ritiumu-ion totoka: Haumaru ake i te makariri (kāore he wai e tio/e turuturu ana), engarika ngaro tonu te kawe hikonā te mea kāore e pai te kawe a ngā mea totoka i ngā katote i ngā pāmahana iti.

Ngā otinga rangahau o nāianei

1. Ngā irahiko whākawa

   • Ahakoa kei raro iho i te 0 °C, ka mau tonu te kawe hiko o ētahi irahiko totoka kei roto i te whanariki.

   • He mea pai tēnei mō ngā waka hiko i ngā rohe makariri.

2. Ngā ranunga polymer-uku

   • Mā te whakakotahi i ngā pūmua ngāwari me ngā matūriki uku ka pai ake te rere o te katote i ngā pāmahana iti, me te pupuri tonu i te haumaru.

3. Hangarau atanga

   • Kei te whakawhanakehia ngā paninga, ngā paparanga ārai rānei hei pupuri i te pumau o te pānga o te irahiko me te irahiko i te wā e rerekē ana te pāmahana.

4. Ngā pūnaha whakamahana-mua i roto i ngā EV

   • Pērā i ngā EV o ēnei rā e whakamahana ana i ngā pākahiko wai i mua i te utunga, ka whakamahia pea e ngā EV totoka o muri maiwhakahaere werahei pupuri i ngā pūtau i roto i tō rātou awhe pai (15–35 °C).

Whakarāpopototanga:
He pono ka pāngia ngā pākahiko totoka e te makariri, ko te nuinga nā te iti o te kawe hiko katote me te ātete atanga. He haumaru tonu i te katote lithium wai i roto i aua āhuatanga, engarika taea e te mahi (te whānuitanga, te tere utu, te putanga hiko) te heke iho i raro i te 0 °CKei te kaha te mahi a ngā kairangahau ki ngā irahiko me ngā hoahoa e mau tonu ana te hiko i te makariri, me te whai kia pono te whakamahinga i roto i ngā EV ahakoa i ngā āhuarangi hotoke.
