He rerekētanga nui kei roto i ngā whakaritenga taupū mō te kōka hinu kua whakakāwhatia puta noa i ngā mara tono rerekē. I roto i te mara o ngā rauemi anode pākahiko lithium-ion, ka aro nui ki te mahi hikohiko, te tohatoha rahi matūriki, te horahanga mata motuhake, me te whakahaere parakore. He rerekē, ko te mara o ngā tokotoko hiko (pērā i ngā hiko karāwhata) ka aro nui ake ki te kawe hiko, te kaha miihini, te pumau wera, me te whakahaere i te ihirangi pungarehu. Kei raro nei tētahi tātari taipitopito:
I. Papa Rauemi Anode Pūhiko Lithium-ion
- Te Mahi Hikohiko hei Tohu Matua
Te Pūmanawa Motuhake mō te Utu/Tukunga Tuatahi: Me eke ki te ≥350.0 mAh/g (Paerewa ā-Motu GB/T 24533-2019) hei whakarite i te kiato pūngao pākahiko. Te Whai Huatanga o te Coulombic Tuatahi: Ko te whakaritenga o te ≥92.6% e whakaata ana i te ōwehenga o te pūmanawa ka taea te huri i te wā o te huringa tuatahi. Ngā Tawhā Hanganga Tioata: Ko te mokowā papa (002) (d002) ka whakahaeretia mā te whakamātautau X-ray diffraction (XRD) hei arotau i te tohu graphitization, hei whakaiti i ngā hapa whatunga, hei whakarei ake i te nekenekehanga irahiko. 2. Te Tohatoha Rahi Matūriki me te Horahanga Mata Motuhake
Te Tohatoha Rahi o te Matūriki: Me whakahaere te rahi toharite o te matūriki (D50) me te whānui o te tohatoha hei whakapai ake i te tukanga whakarite paru pākahiko me te kiato pūngao rōrahi. Mā ngā matūriki iti e whakakī ana i ngā āputa o ngā matūriki nui ka taea te whakapai ake i te kiato whakakī. Te Horahanga Mata Motuhake: Me taurite i waenga i te mahi tauhohenga me te ngaronga kaha tuatahi. Ka nui ake te horahanga mata motuhake ka whakanui ake i te whakamahinga o te here me te ātete ā-roto, engari ko te korenga o te horahanga mata motuhake ka whakawhāiti i te pai o te tango i te lithium-ion. 3. Te Whakahaere i te Parakore me te Parakore
Te Ihirangi Waro Pūmau: Me whakarite kia ≥99.5% te nui hei whakaiti i te pānga o ngā wāhanga kore mahi ki te mahi hikohiko. Te Uara Makuku me te pH: Me tino whakahaere kia kore ai e mimiti te makuku o te rauemi, e tauhohe rānei ki te electrolyte, ka pā ki te pumau o te tukanga whakarite paru.
II. Te Marae Irahiko (hei tauira, te Irahiko Karāpiti)
- Te Aroturuki me te Kaha Mīhini
Ātete: Me iti iho i te taumata μΩ·m hei whakaiti i te ngaronga pūngao i te wā e whakamahia ana te hiko. Kaha Piko: Me kaha piko teitei hei ātete i te ahotea miihini i te wā e whakamahia ana, ā, hei ārai i te pakaru. Tauwehenga Rino: Me taurite te pakari me te pakari hei karo i te pakaru nā te ru wera, te wiri miihini rānei. 2. Te Pūmautanga Wera me te Ātete Waikura
Tau Whakawhanui Wera: Me iti hei whakaiti i ngā panonitanga ā-ahu i ngā pāmahana teitei, me te ārai i te hononga ngoikore i waenga i te hiko me te utu oumu. Te Ihirangi Pungarehu: Me ≤0.5% hei whakaiti i te pānga o ngā poke ki te ātete ki te waikura hiko. Ka taea e ngā huānga konganuku i roto i te pungarehu te whakatere i te waikura hiko me te whakapoto i te roa o te mahi. 3. Te Whakarerekētanga o te Tukanga Hanga
Kiato Papatipu: He mea tika kia nui te kiato papatipu hei whakarei ake i te kiato o te hikohiko me te whakapai ake i te kawe hiko me te ātete ki te waikura. Tukanga Whakakī me te Whakakāwhata: E hiahiatia ana ngā whakakī maha me te whakakāwhata pāmahana teitei (≥2800°C) hei whakarei ake i te raupapa tioata me te whakaiti i te ātete.
III. Te Whakatakotoranga Tohu e Aratakihia ana e ngā Horopaki Taupānga Pūhiko Ritiuma-ion Ngā Rauemi Anode: Me tutuki i a rātou ngā hiahia mō te kiato pūngao teitei me te roa o te ora huringa, nō reira he whakaritenga pakari mō te mahi hikohiko, te tohatoha rahi matūriki, me te parakore. Ngā Tokotoko Hikohiko: Me mahi pumau i raro i ngā pāmahana teitei me ngā kiato iahiko teitei, nō reira he nui ake te aro ki te kawe hiko, te kaha miihini, me te pumau wera.
