He mea tino nui anō hoki te taiao e whakamahia ana te pākahiko lithium polymer hei awe i tōna roanga huringa. I roto i ēnei, he mea tino nui te pāmahana taiao. Ka pā te pāmahana taiao iti rawa, teitei rawa rānei ki te roanga huringa o ngā pākahiko Li-polymer. I roto i ngā tono pākahiko hiko me ngā tono e nui ana te awe o te pāmahana, me whakahaere te wera o ngā pākahiko Li-polymer hei whakapai ake i te whai huatanga o te pākahiko.

Ngā take o te huringa pāmahana ā-roto o te pākahiko Li-polymer

MōNgā pākahiko Li-polymer, ko te wera o roto e puta mai ana ko te wera tauhohenga, te wera pōraritanga me te wera Joule. Ko tētahi o ngā take matua mō te pikinga o te pāmahana o te pākahiko Li-polymer ko te pikinga o te pāmahana i puta mai i te ātete o roto o te pākahiko. Hei tāpiri, nā te whakatakotoranga matotoru o te tinana pūtau wera, ka nui ake te wera ka kohia e te rohe waenga, ā, ka iti ake te rohe taha, ka piki ake te kore taurite o te pāmahana i waenga i ngā pūtau takitahi o te pākahiko Li-polymer.

Ngā tikanga whakahaere pāmahana pākahiko lithium polymer

1. Te whakatikatika ā-roto

Ka whakanohoia te pūoko pāmahana ki te wāhi tino kitea, ko te nui rawa o te huringa pāmahana, inā koa ko te pāmahana teitei me te iti rawa, me te pokapū o te pūhiko lithium polymer he wāhi kaha ake.

1. Te ture ā-waho

Te whakahaere whakamatao: I tēnei wā, i runga i te uaua o te hanganga whakahaere wera o ngā pākahiko Li-polymer, he maha o rātou e whakamahi ana i te hanganga māmā o te tikanga whakamatao hau. Ā, i runga i te ōritetanga o te tohatoha wera, he maha o rātou e whakamahi ana i te tikanga hauhautanga whakarara.

1. Te whakahaere pāmahana: ko te hanganga whakamahana māmā ko te tāpiri i ngā pereti whakamahana ki runga me raro o te pākahiko Li-polymer hei whakatinana i te whakamahana, he raina whakamahana i mua me muri i ia pākahiko Li-polymer, i te whakamahi rānei i te kiriata whakamahana kua takaihia ki te taha.Pūhiko Li-polymermō te whakamahana.

Ko ngā take matua mō te whakahekenga o te kaha o ngā pākahiko lithium polymer i ngā pāmahana iti

1. Te kawe hiko ngoikore o ngā irahiko, te kore e pai te mākū me te uruhanga o te diaphragm, te puhoi o te hekenga o ngā katote lithium, te puhoi o te tere whakawhiti utu i te atanga irahiko/irahiko, me ētahi atu.

2. Hei tāpiritanga, ka piki ake te aukati o te kiriuhi SEI i ngā pāmahana iti, ka whakaroa i te tere o ngā katote lithium e haere ana i roto i te atanga irahiko/irahikohiko. Ko tētahi o ngā take mō te pikinga o te aukati o te kiriata SEI he māmā ake te tango atu o ngā katote lithium i te irahiko kino i ngā pāmahana iti, ā, he uaua ake te whakauru.

3. I te wā e utu ana, ka puta mai te konganuku lithium ka tauhohe ki te electrolyte hei hanga i tētahi kiriata SEI hou hei taupoki i te kiriata SEI taketake, ka whakanui ake i te ātete o te pākahiko, ā, ka heke te kaha o te pākahiko.

Te pāmahana iti ki te mahi a ngā pākahiko lithium polymer

1. te pāmahana iti i runga i te mahi utu me te tukunga

I te hekenga o te pāmahana, ko te ngaohiko tukunga toharite me te kaha tukunga ongā pākahiko lithium polymerKa whakaitihia, ina koa ka -20 ℃ te pāmahana, ka tere ake te heke o te kaha tuku pākahiko me te ngaohiko tuku toharite.

2. Te iti o te pāmahana i runga i te mahi a te huringa

Ka tere ake te pirau o te kaha o te pākahiko i te -10℃, ā, ko te kaha anake e toe ana ko te 59mAh/g i muri i te 100 huringa, me te 47.8% te pirau o te kaha; ka whakamatautauria te pākahiko kua tukuna i te pāmahana iti i te pāmahana rūma mō te utu me te tango, ā, ka tirohia te mahi whakaora kaha i roto i te wā. Ka whakahokia tōna kaha ki te 70.8mAh/g, me te ngaronga kaha o te 68%. E whakaatu ana tēnei he nui ake te pānga o te huringa pāmahana iti o te pākahiko ki te whakaora i te kaha o te pākahiko.

3. Te pānga o te pāmahana iti ki te mahi haumaru

Ko te utu i te pākahiko lithium polymer ko te tukanga o te hekenga o ngā katote lithium mai i te irahiko pai mā te hikohiko kua whakauruhia ki roto i te rauemi kino, ka honoa ngā katote lithium ki te polymerization o te irahiko kino, ka hopukina he katote lithium e ngā ngota waro e ono. I ngā pāmahana iti, ka whakaitihia te mahi tauhohenga matū, i te mea ka puhoi haere te hekenga o ngā katote lithium, kāore anō kia whakauruhia ngā katote lithium ki roto i te irahiko kino kua whakaitihia ki te konganuku lithium, ā, ka heke te ua ki runga i te mata o te irahiko kino hei hanga i ngā dendrite lithium, ka taea te wero ngāwari i te diaphragm ka puta he ara iahiko poto i roto i te pākahiko, ka taea te kino i te pākahiko me te puta he aituā haumaru.

Hei whakamutunga, me whakamahara tonu mātou ki a koe, he pai ake kia kaua e utua ngā pākahiko lithium polymer i te takurua i ngā pāmahana iti. Nā te pāmahana iti, ka puta he tioata iona mai i ngā katote lithium e piri ana ki te hiko kino, ka wero tika i te diaphragm, ka puta he ara iahiko poto poto, ka pā ki te roanga o te ora me te mahi, ka pahū tika. Nō reira, ko ētahi tāngata e whakaata ana i te kore e taea te utu i te pākahiko lithium polymer i te takurua, nā te wehenga atu i te pūnaha whakahaere pākahiko nā te tiakitanga o te hua.
