I roto i te tukanga hanga o ngā pākahiko lithium, ko te mīhini paninga, hei taputapu matua, ka pā tika te mahi o tōna turanga ki te tika o te paninga me te kounga o te hua o ngā pākahiko lithium. He mea nui te rerekētanga o te pāmahana e pā ana ki te pumau o ngā mīhini paninga. Ko te rerekētanga o te ātete pāmahana i waenga i ngā turanga karāhe me ngā turanga rino maka kua waiho hei whakaaro matua mō te whiriwhiri taputapu i roto i ngā umanga hanga pākahiko lithium.
Te tauwehenga o te whakawhānui wera: Te painga o te "ātete pāmahana" o te karāhe
Ko te tauwehenga whānui wera e whakatau ana i te pumau o te āhua o te rauemi ina rerekē te pāmahana. Ko te tauwehenga whānui wera o te turanga rino maka he tata ki te 10-12 ×10⁻⁶/℃. I roto i te taiao piki me te heke o te pāmahana o ngā awheawhe paninga pākahiko lithium, ahakoa he iti noa ngā huringa pāmahana ka taea te whakaputa i te rerekētanga āhua nui. Hei tauira, ina rerekē te pāmahana i roto i te awheawhe mā te 5℃, ka taea e te turanga rino maka 1-mita te roa te whakawhānui me te whakaheke i te āhua 50-60 μm. Ka puta he rerekētanga i roto i te āputa i waenga i te roera paninga me te pepa hiko nā tēnei rerekētanga, ka hua ake he matotoru paninga kāore i te ōrite, ā, ka pā ki te kaha me te ōritetanga o ngā pākahiko lithium.
He rerekē, ko te tauwehenga o te whakawhānui wera o te turanga karāhe he (4-8) ×10⁻⁶/℃ anake, arā, he haurua pea i te rino maka. I raro i te pikinga pāmahana kotahi o te 5℃, ko te whakarerekētanga o te turanga karāhe 1-mita te roa he 20-40 μm anake, ā, tata kore e arohia te huringa āhua. I roto i te tukanga whakaputa tonu mō te wā roa, ka taea e te turanga karāhe te pupuri i te āhua pumau, me te whakarite i te tūranga whanaunga tika i waenga i te roera paninga me te pepa hiko, me te pupuri i te pumau o te tukanga paninga, me te whakarato i te taurangi pono mō te whakaputa pākahiko lithium tino pumau.
Te kawe wera: Ko te āhuatanga "ārai whakamahana" o te karāhe
Haunga ngā panonitanga ā-ahu e puta mai ana i te whānui o te wera, ka pā anō hoki te kawe wera o ngā rauemi ki te ōritetanga o te tohatoha pāmahana i roto i ngā taputapu. He pai te kawe wera o te rino maka. Ina puta te wera i roto i te mīhini paninga nā te mahi a te motuka, te waku o te roera paninga, me ētahi atu, ka tere te kawe wera o te turanga rino maka, ka piki ake te pāmahana o te mata o te turanga, ka kore e taurite te tohatoha. Ka puta he ahotea wera ki te turanga nā tēnei rerekētanga pāmahana, ka kaha ake te whakarerekētanga. I taua wā anō, ka pā pea ki te mahi noa o ngā pūoko tika me ngā wāhanga whakahaere e karapoti ana.
He ngoikore te karāneti hei kawe wera, ā, ko te kawe wera he 2.7-3.3W/ (m · K) anake, he iti iho i tērā o te rino maka i te 40-60W/ (m · K). I te wā e whakahaerehia ana te mīhini paninga, ka taea e te turanga karāneti te aukati i te kawe wera o roto, ka whakaiti i te piki me te heke o te pāmahana i runga i te mata o te turanga me te whakaputanga o te ahotea wera. Ahakoa ka roa te mahi a te mīhini paninga i raro i te kawenga nui, ka taea tonu e te turanga karāneti te pupuri i te āhua pāmahana pumau, ka karo i te whakarerekētanga o ngā taputapu me te hekenga o te mahi i puta mai i te pāmahana kore taurite, me te hanga i tētahi taiao pāmahana pumau mō te tukanga paninga.
Te pumau i raro i te huringa pāmahana: Te kaha o te karāhe ki te "ātete pāmahana mō te wā roa"
Ko te hanga pākahiko lithium te tikanga me mahi tonu ngā taputapu mō te wā roa. I ngā huringa pāmahana auau (pēnei i te whakamatao i te pō me te whakamahana i te awatea), he mea tino nui te pumau o te rauemi turanga. I raro i te pānga auau o te whakawhānui me te whakaheke wera, ka ngawari te pakaru o te turanga rino maka ki roto, ka heke te kaha o te hanganga, ka pā ki te roa o te mahi a te taputapu. E whakaatu ana ngā raraunga rangahau e tika ana, i muri i te 1000 huringa pāmahana (me te awhe rerekētanga pāmahana o te 20-40℃), ka taea e te hohonutanga o te pakaru o te mata o te turanga rino maka te eke ki te 0.1-0.2mm.
He tino pai te ātete o ngā turanga karāneti ki te ngenge nā te hanganga matotoru o roto o te tioata kohuke. I raro i ngā āhuatanga whakamātautau huringa pāmahana kotahi, kāore e kitea he pakaru o te turanga karāneti, ā, ka roa te pupuri i te hanganga. Mā tēnei pumau teitei i raro i te huringa pāmahana ka taea e te turanga karāneti te whakatutuki i ngā whakaritenga mahi kaha me te roa o te hanga pākahiko lithium, ka whakaiti i te auau tiaki me te wā kore mahi o ngā taputapu i puta mai i ngā raruraru turanga, ā, ka whakapai ake i te pai o te whakaputa.
I roto i te horopaki o ngā whakaritenga tino pakari mō te tika me te pumau i roto i te hanga pākahiko lithium, ko ngā turanga granite, me te iti o te tauwehenga o te whakawhānui wera, te kawe wera pai me te pumau huringa pāmahana tino pai, ka nui ake te pai ake o ngā turanga rino maka i runga i te ātete pāmahana. Ko te whiriwhiri i tētahi mīhini paninga pākahiko lithium me te turanga granite ka taea te whakapai ake i te tika o te paninga, te whakarite i te kounga o ngā hua pākahiko lithium, te whakaiti i ngā mōrearea taputapu i te wā o te tukanga whakaputa, ā, ka noho hei tautoko nui mō te whakatairanga i te whanaketanga o te umanga pākahiko lithium ki te mahi teitei ake.
