Ngā Ripa i roto i te Pēke Pūhiko Lithium-Ion: He Tirohanga Whānui

He wāhanga nui ngā ripa i roto i ngā pākahiko lithium-ion putea, e mahi ana hei piriti kawe hiko i waenga i ngā irahiko o roto o te pākahiko me ngā ara iahiko o waho. Ehara i te mea he hononga noa iho, engari he mahi nui tā rātou ki te whakarite i te haumaru o te pākahiko, te mahi hiri, me te whai huatanga whānui. Ka tūhuratia e tēnei tuhinga ngā momo, ngā rauemi, ngā āhuatanga mahi, me ngā whakamahinga o ēnei wāhanga nui, e tuku ana i ngā māramatanga whai hua mō ngā kaihanga me ngā miihini.

He aha ngā Ripa Pūhiko?

I te pūtake, he hanganga hiato ngā ripa pākahiko e rua ngā wāhanga matua: he rīpene whakarewa me te kiriata kirihou (piri ripa). Ko te rīpene whakarewa te kaiārahi, e whakawhiti ana i te iahiko hiko i waenga i ngā irahiko pai/kino o te pākahiko me ngā taputapu o waho. I taua wā, ka whakaratohia e te kiriata kirihou he hiri hei ārai i te turuturu o te irahiko hiko, ā, ka ārai i te rīpene whakarewa mai i ngā ara iahiko poto.

1. Ngā ripa paihe mea hanga i te konumohe (Al) nā te mea he pai rawa te kawe hiko me te ātete ki te waikura.
2. Ngā ripa kinowhakamahia te nikara (Ni) te parahi whakakikoruatia ki te nikara (Ni-Cu) rānei. He mea noa ngā ripa nikara i roto i ngā taputapu matihiko iti, ko ngā ripa parahi whakakikoruatia ki te nikara ia—he mea nui mō te kaha kawe iahiko teitei—he mea pai mō ngā pākahiko hiko me ngā tono tere teitei.

Te Whakarōpūtanga o ngā Ripa

Ka whakarōpūtia ngā ripa i runga i te rauemi, te momo piripiri, me te takai, ia ripa e tika ana mō ngā whakamahinga motuhake:

1. Mā te Rauemi Ripanga Whakarewa

1. Ngā ripa konumohe (Al)E whakamahia ana mō ngā irahiko pai. Ka taea hoki te whakamahi hei irahiko kino i roto i ngā pākahiko me ngā anode lithium titanate.
2. Ngā ripa nikara (Ni)Mō ngā irahiko kino anake i roto i ngā taputapu iti-mana pēnei i ngā waea atamai, ngā papahiko, me ngā peeke mana.
3. Ripa parahi (Ni-Cu) whakakikoruatia nikelI hangaia mō ngā irahiko kino i roto i ngā pākahiko hiko (hei tauira, ngā waka hiko) me ngā pākahiko tere-teitei, e whakakotahi ana i te kawe hiko o te parahi me te ātete ki te waikura o te nikara.

2. Momo Piripiri Mā te Ripa

Ka whakarōpūhia e ngā mākete ā-rohe ngā piripiri ripa mā te tae, e whakaatu ana i ngā rerekētanga o te kounga me te whakamahinga:

1. Ngā ripa piri pangoWhakamahia i roto i ngā pākahiko matihiko awhe-iti ki te awhe-waenga. Ka tūpono te pakaru o tōna hanganga (he matua kiriata PEN me ngā paparanga PP kua whakarerekētia) i roto i te wā.
2. Ngā ripa piri kōwhaiHe mea noa i roto i ngā pākahiko hiko waenga-rahi. Ahakoa he māmā ake te hiri, ka taea e tōna uho kore-whatu te mimiti i te makuku, ka pupuhi ai te pākahiko.
3. Ngā ripa piri māHe pai ake mō ngā taputapu matihiko kounga teitei, ngā pākahiko hiko, me ngā pākahiko tere teitei. Kei te wātea i roto i ngā hoahoa paparanga kotahi, toru, rima rānei, ko ngā piripiri ma paparanga toru (me ngā matua PP) e tuku ana i te hiri pai rawa atu, ā, kāore he mōrearea mo te wehewehe.
4. Ngā ripa kua hurihia: Ngā rīpene tonu kua takaihia hei rōra, he mea tino pai mō ngā raina whakaputa aunoa.
5. Ngā ripa rauNgā ripa takitahi kua whakatakotoria i waenganui i ngā rau kirihou, he pai mō ngā tukanga ā-ringa, ā-haurua rānei.

3. Mā te Tākai

1. Ngā ripa kua hurihia: Ngā rīpene tonu kua takaihia hei rōra, he mea tino pai mō ngā raina whakaputa aunoa.
2. Ngā ripa rauNgā ripa takitahi kua whakatakotoria i waenganui i ngā rau kirihou, he pai mō ngā tukanga ā-ringa, ā-haurua rānei.

Ngā Rauemi Matua me te Mahi

Ko te mahi a ngā ripa e whakawhirinaki ana ki ngā rauemi e hanga ana i aua ripa:

1. Ngā rīpene whakarewaKo te konumohe (AL1050 koranu) me te parahi (TU1 parahi kore-hāora) e paingia ana mō ō rātou kawe hiko, ngāwari, me te ātete ki te waikura. Ko te whakakikorua nikara i runga i ngā rīpene parahi ka ārai i te waikura me te whakarei ake i te kaha ki te whakarewa.
2. Ngā piripiri ripaKo te nuinga o ngā piripiri he mea kawemai mai i Hapani, nā te mea he uaua ki ngā rauemi PP o te whare te whakatutuki i ngā whakaritenga taumaha ngota tino pakari. Ka whakatauritehia e ngā piripiri kounga teitei (hei tauira, ngā piripiri mā paparanga-toru) te ātete wera (te ira rewa ~147°C) me te ngāwari, ka whakarite kia pono te hiri me ngā kiriata kirihou konumohe.

Te Hanga me te Mana Kounga

Ko te hanga i ngā ripa mahi-teitei me tino tika:

1. Ngā tukanga whakakikoruaKo ngā ripa parahi whakakikoruatia ki te nikara ka whakamahi i te whakakikoruatanga hiko (1.8±0.3μm te matotoru) te whakakikoruatanga kore-hiko rānei (1.0±0.3μm te matotoru) kia ōrite ai te hipoki.
2. Te tapahi tahaKo ngā rīpene whakarewa matotoru atu i te 0.2mm me kuti ngā taha hei karo i ngā raruraru whakamahana me ngā mōrearea turuturu.
3. Whakamātautau pakari:
   1. Ngā whakamātautau rumaki irahikoMe mau tonu te kaha hiri o ngā ripa >15N/15mm i muri i ngā hāora 24 i te 85°C.
   2. Ngā whakamātautau pikoMe tu atu ngā ripa ki te 5–7 piko (i runga i te matotoru) kia mau ai te pakari i roto i ngā taiao wiri (hei tauira, ngā waka hiko).

Ngā Tikanga Hononga Ripa

He maha ngā tikanga hei hono i ngā ripa ki ngā ara iahiko o waho:

1. Te whakapiri ā-mīhiniHe iti te utu o ngā hononga mā te keri me te whakawiri, engari me āta whakahaere te matotoru.
2. Te whakapiriKa mahi te tūhono M51 pāmahana-iti mō ngā konganuku rerekē (hei tauira, te parahi me te konumohe) engari he utu nui.
3. Te whakarewanga orooroKo te tikanga pai mō ngā pākahiko hiko, mā te whakamahi i ngā wiri auau-tiketike hei here i ngā pepa takai angiangi (0.01mm) me te kore e nui te wera.

Whakamutunga

Ahakoa he iti noa ngā ripa, engari he pānga tika tō rātou hoahoa me te kounga ki te mahi a te pēke pākahiko. I te tipu haere o te tono mō ngā pākahiko haumaru ake, whai hua ake i roto i ngā waka hiko me te rokiroki pūngao, ka noho tonu te whanaketanga o ngā rauemi ripa (hei tauira, ngā piripiri paparanga maha) me te hanga (hei tauira, te whakakikoruatanga tika). Ko te mārama ki ngā āhuatanga o te ripa te mea nui ki te arotau i te pono me te roa o te pākahiko i roto i ngā tono kanorau.
