I roto i te mara o ngā pū mirimiri, ko te pākahiko hei"ngākau"o te pū mirimiri, koinei hoki te take matua hei wehewehe i ngā painga me ngā ngoikoretanga o te pū mirimiri. Ko te nuinga o ngā kaihanga pū mirimiri kei te mākete, hei whakaiti i ngā utu, hei utu mō te pai ake o te tohanga, nō reira kāore e whakaatu ki ngā kaihoko ā rātou hua e whakamahia ana i roto i te pākahiko. Ka piri tonu a Beoka ki te pākahiko momo mana 3C waitohu raina tuatahi taketake, ka whakakore i ngā wāhanga taketake kino, tuarua.
Ko ngā pū mirimiri Beoka i pai ki te Tianjin Lishen Battery Company Limited (e kiia nei ko te Lishen Battery) ngā pākahiko taumata-A, ko tēnei pākahiko i roto i te haumaru, te mahi, te roa me ētahi atu āhuatanga o ngā painga tino pai. Hei māngai hangarau-teitei ā-motu, ko Tianjin Lishen te hinonga R&D me te hanga pākahiko lithium-ion tuatahi i Haina, me te 23 tau o te wheako ki te R&D me te hanga pākahiko lithium-ion. I te tau 2018, 11 ngā tohunga mātauranga o te Chinese Academy of Engineering, 574 ngā tohunga e whiwhi ana i ngā tahua motuhake a te kāwanatanga i raro i te Kaunihera ā-Motu, 18 ngā taiwhanga matua taumata-kāwanatanga, 20 ngā teihana rangahau pou-toketā, ā, kei mua i te umanga lithium o te ao e pā ana ki te wahanga mākete teitei o te ao.
Nā, he aha ngā painga nui o te pūnaha pākahiko e whakamahia ana i roto i ngā pū mirimiri Beoka?

E mōhio ana tātou katoa, ko te nuinga o ngā aituā o ngā waka hiko pūngao hou ka meinga te pākahiko kia mura. E whakaatu ana tēnei i te hiranga o te pākahiko ki ngā kino o waho. Ko ngā pākahiko e whakamahia ana i roto i ngā waka hiko i konei, me ngā pākahiko e whakamahia ana i roto i ngā pū mirimiri whānui, he pākahiko lithium katoa. Ā, ko tētahi o ngā āhuatanga nui o ngā pākahiko lithium ko te matotoru o te pūngao.
He maha ngā pū mirimiri iti e whakamahia ana i roto i ngā pākahiko lithium e toru, e whā rānei ngā waitohu, tae atu ki ngā waitohu rerekē. Kāore he hoahoa haumaru me te pūnaha whakamātautau kounga tino tika. Mēnā he pānga iti, he werohanga, he werohanga, he werohanga iti, he tino tūpono ka mura, ka pahū. Ehara i te mea nā ngā āhuatanga matū tino kaha o te lithium anake tēnei, engari he hononga tata hoki ki te hoahoa haumaru o ngā pākahiko lithium.
Ko te pākahiko Lithium A e whakamahia ana i roto i te pū mirimiri Beoka he anga maitai o waho, me te takirere whakaiti pēhanga kei te tihi o te pākahiko, ka taea te tuku hau ki waho ina nui rawa te pēhanga i roto hei ārai i te pahūtanga.
Heoi anō, i te wā o te wera nui (130℃), te utu nui rawa, te tukunga nui rawa, te ara iahiko poto, te whakaputanga hiko, me ngā whakamātautau maturuturu o ngā pūtau pākahiko kua utua katoatia i raro i te Pūhiko LiShen, i pai te mahi a ngā pākahiko me te kore he ahi, he pahūtanga, me ētahi atu āhuatanga tino kino.
PaingaE ruaTe huihuinga taketake,Lte whakamahinga tonu
Hei kaihoko, ina hoko ana i ngā hua hiko me ngā mea hiko, ko te huarahi māmā ki te taka ki te mahanga ko te utu mō te waitohu tuturu, ka tiki i ngā taonga iti iho te kounga.Nō reira, hei kaihoko, me pēhea tātou e mōhio ai ki te pono o te pākahiko?
I te nuinga o te wā, ka taea e tātou te tiro i te waikura o ngā pou pai me ngā pou kino o te pākahiko, te wetewete i te kiri, te ine i te ngaohiko me te ātete ā-roto ki ngā raraunga mana, hei wehewehe ko tēhea te pākahiko tuarua. Ko ngā pākahiko kounga iti he maha ngā wā kāore he ingoa o te kaihanga, ā, kāore e taea te rite ki tētahi waitohu taumata tuatahi pērā i ngā pākahiko Lixin, ka taea e koe te tirotiro tika i ngā mōhiohio hanga mā te waehere QR i tāia ki te laser.
He mea nui kia mōhio koe ko te roa o te ora o ngā pākahiko lithium e pā ana ki te wā utu. Mēnā ka nui rawa te utu mō te wā roa, ka ngāwari te wehe atu o ngā katote lithium i roto i te pākahiko mai i te anode, ka whakapoto i tōna roanga mahi. Ko ngā pākahiko kua whakamahia i roto i ngā pū mirimiri kounga iti, he 50-200 noa iho ngā wā utu me te wā tuku. I muri i te whakamahinga roa, kua tino iti te nui o ngā katote lithium hohe, e whakaatuhia ana i roto i te mahi a te pū mirimiri noa he "iti haere, kāore e roa".
Kei te whakamahi te Pū Mirimiri Beoka i te pākahiko Lixin, e kī taurangi ana ka tukuna tika mai e te kaihanga taketake, ā, ka taea tonu te kī taurangi neke atu i te 80% o te penapena hiko i muri i te 500 wā o te utu me te tango.
Painga Tuatoru: Momo Mana 3CBte whare inu,PmanaSakiaki
Ka taea e te pākahiko kounga te whakarato i te kaha pupuhi me te roa o te ora mō ngā pū mirimiri. E ai ki te momo tukunga, ka wehea ngā pākahiko noa ki ngā pākahiko momo kaha me ngā pākahiko momo mana. He nui te kaha o ngā pākahiko momo kaha engari he papatahi te tukunga, ā, kāore e taea te tukunga i runga i te whakarea kawenga mahi. Ina koa, kāore e taea e rātou te whakatutuki i te tukunga whakarea tere e hiahiatia ana e ngā taputapu pēnei i ngā pū mirimiri e whakamahi ana i ngā motuka taipana teitei.
I tētahi atu taha, ko ngā pākahiko momo mana he tere tere te tukunga tere me te ngāwari ki te urutau. Ka taea e ia te whakapūmau i te haumaru, ā, i te wā kotahi ka tautoko i te hiahia kia nui ake te whakapaunga mana o te motuka i raro i ngā kawenga nui. Nō reira, ka whakamahia e te pū mirimiri Beoka te pākahiko momo mana Lixin 3C, ka taea te whakanui ake i te ia tere ina mahi ana i raro i te kawenga, ā, ka whakarato i te mana kaha me te pupuhi kia rere ai te motuka, kia uru ai te putanga o te kaha patu ki roto i ngā uaua, kia tae atu ai ki te hohonutanga o te fascia.
Painga Tuawhā: WhakariteaAmatatauIatamaiCwhakahaereChope,Shaumaru me teShaumaru
Neke atu i te 20 tau a BEOKA e arotahi ana ki te ao o te whakaora tinana me te whakaora. Neke atu i te 200 ngā mana pateni i te kāinga me tāwāhi, he nui ngā wheako o BEOKA ki te whakawhanake me te hanga i ngā Whakaoho Uaua Hōhonu (DMS) kounga hauora, ā, e tohe ana kia whakamahia ngā paerewa hanga taputapu hauora ngaio, nō reira ka whakawhanake me te hoahoa motuhake i āna pū mirimiri "putanga kāinga".
Nō reira, hei whakahaere pūmau i te haumaru o te pākahiko, ka whakamahia hoki e Beoka tētahi maramara whakahaere atamai matatau, ka taea te whai wāhi maha ki te tiaki i ngā taputapu me ngā pūmanawa pākahiko, hei karo i te nui rawa o te ngaohiko, te nui rawa o te iahiko, te poto o te ara iahiko, te nui rawa o te pāmahana me ētahi atu raruraru, hei karo i te tahunga o ngā wāhanga motuka me te IC, kia pumau ake ai, kia tika ake ai te putanga o te pū mirimiri, kia haumaru ake ai, kia māia ake ai hoki te whakamahinga.
