Pūhiko lithium (Li-ion, Pūhiko Lithium Ion)He māmā ngā pākahiko lithium-ion, he nui te kaha, ā, kāore he pānga mahara, nō reira e whakamahia whānuitia ana – he maha ngā taputapu matihiko e whakamahi ana i ngā pākahiko lithium-ion hei pūtake hiko, ahakoa he utu nui. He tino teitei te kaha o ngā pākahiko lithium-ion, ā, ko tōna kaha he 1.5 ki te 2 ngā wā i tērā oNgā pākahiko NiMHhe rite te taumaha, ā, he tino iti te tere tuku-ake. Hei tāpiri, kāore he "pānga mahara" o ngā pākahiko lithium-ion, ā, kāore he matū paitini kei roto, ā, ko ētahi atu painga he take nui anō hoki mō tōna whakamahinga whānui. Kia mōhio hoki ko ngā pākahiko lithium he mea tohu ki te pākahiko lithiumion 4.2V, te pākahiko tuarua lithium 4.2V, te pākahiko lithiumion 4.2V rānei i waho.

pākahiko lithium 18650
Ko te 18650 te pūtake o te pākahiko lithium-ion – he tauira pākahiko lithium-ion paerewa i whakatakotoria e te kamupene SONY Hapanihi hei penapena utu, ko te 18 te tikanga he diameter 18mm, ko te 65 te tikanga he roa 65mm, ko te 0 te tikanga he pākahiko porotaka. Ko te 18650 te tikanga he diameter 18mm, ko te roa 65mm. Ā, ko te tauira nama 5 he 14500, 14 mm te diameter me te 50 mm te roa. Ko te pākahiko whānui 18650 he nui ake te whakamahinga i roto i te ahumahi, he iti noa te whakamahinga a te iwi whānui, he mea noa te whakamahi i roto i ngā pākahiko pona me ngā rama rama teitei.

Ko ngā pākahiko 18650 noa e wehea ana ki ngā pākahiko lithium-ion, ngā pākahiko lithium rino phosphate. Ko te ngaohiko pākahiko lithium-ion he 3.7v te ingoa, ko te ngaohiko tapahi utu he 4.2v, ko te pākahiko lithium rino phosphate he 3.2V te ingoa, ko te ngaohiko tapahi utu he 3.6v, ko te kaha he 1200mAh-3350mAh te tikanga, ko te kaha he 2200mAh-2600mAh. Ko te ariā o te ora o te pākahiko lithium 18650 he 1000 ngā wā.

Ko te pākahiko Li-ion 18650 te mea e whakamahia nuitia ana i roto i ngā pākahiko pona nā te mea he nui te kaha mō ia waeine kiato. Hei tāpiri, he whānuitia te whakamahinga o te pākahiko Li-ion 18650 i roto i ngā mara hiko nā te mea he tino pumau i roto i te mahi: he mea whakamahi whānuitia i roto i ngā rama kounga teitei, te pūhiko kawe, te tuku raraunga ahokore, ngā kākahu me ngā hu mahana hiko, ngā taputapu kawe, ngā taputapu rama kawe, te pūreretā kawe, ngā taputapu ahumahi, ngā taputapu hauora, me ētahi atu taputapu hauora, me ētahi atu.

He rite tonu te pūhiko Li-ion kua tohua ki te 3.7V, ki te 4.2V rānei. Ko te 3.7V e pā ana ki te ngaohiko tūāpapa (arā, te ngaohiko noa) i te wā e whakamahia ana te pākahiko, ko te 4.2 volts e pā ana ki te ngaohiko i te wā e utua ana he utu katoa. Ko te pūhiko lithium 18650 ka taea te utu anō, ko te ngaohiko he tohu 3.6, 3.7v rānei, ā, 4.2v ina utua katoatia, he iti noa iho te pānga ki te mana (kaha), ko te kaha matua o te pūhiko 18650 mai i te 1800mAh ki te 2600mAh, (ko te kaha matua o te pūhiko 18650 kei roto i te 2200 ~ 2600mAh), ko te kaha matua he tohu 3500, 4000mAh rānei, neke atu rānei.

E whakaponohia whānuitia ana ka noho te ngaohiko kore-kawenga o te pākahiko Li-ion ki raro iho i te 3.0V, ā, ka pau te hiko (me whakawhirinaki te uara motuhake ki te uara paepae o te papa tiaki pākahiko, hei tauira, he iti iho i te 2.8V, he 3.2V anō hoki). Ko te nuinga o ngā pākahiko lithium kāore e taea te tuku ki te ngaohiko kore-kawenga o te 3.2V, iti iho rānei, ki te kore ka kino te pākahiko ki te tukunga nui rawa (ko ngā pākahiko lithium o te mākete whānui e whakamahia ana me te pereti tiaki, nō reira ka kore e taea e te pereti tiaki te kite i te pākahiko e te tukunga nui rawa, ā, kāore e taea te utu i te pākahiko). Ko te 4.2V te rohe mōrahi o te ngaohiko utu pākahiko, e kiia ana ko te ngaohiko kore-kawenga o ngā pākahiko lithium kua utua ki te 4.2V i te wā e kī ana te hiko, i te tukanga utu pākahiko, ka piki haere te ngaohiko pākahiko i te 3.7V ki te 4.2V, kāore e taea te utu i te pākahiko lithium ki te neke atu i te 4.2V ngaohiko kore-kawenga, ki te kore ka kino anō hoki te pākahiko, koinei te wāhi motuhake o ngā pākahiko lithium.

Ngā Painga

1. Ko te kaha o te pākahiko lithium 18650 he nui te rahi i waenga i te 1200mah ~ 3600mah, ko te kaha o te pākahiko whānui he 800mah noa iho. Ki te whakakotahihia ki te pākahiko lithium 18650, ka taea e te pākahiko lithium 18650 te pakaru i te 5000mah.

2. He roa te ora o te pākahiko lithium 18650, ko te huringa ora o te whakamahinga noa tae atu ki te 500 ngā wā, he nui ake i te rua ngā wā o te pākahiko noa.

3. He mahi haumaru teitei te pākahiko lithium 18650, hei ārai i te āhuatanga porowhita poto o te pākahiko, ka wehea ngā pou pai me ngā pou kino o te pākahiko lithium 18650. Nō reira kua tino whakaitihia te tūponotanga o te porowhita poto. Ka taea e koe te tāpiri i tētahi pereti tiaki hei karo i te utu nui rawa me te tukunga nui rawa o te pākahiko, ka taea hoki te whakaroa i te roa o te ora o te pākahiko.

4. Ko te ngaohiko o te pākahiko lithium 18650 ngaohiko teitei he 3.6V, 3.8V me te 4.2V te nuinga, he teitei ake i te ngaohiko 1.2V o ngā pākahiko NiCd me NiMH.

5. Kāore he pānga mahara Kāore he take ki te whakakore i te mana e toe ana i mua i te utu, he ngāwari ki te whakamahi.

6. Ātete ā-roto iti: He iti ake te ātete ā-roto o ngā pūtau polymer i ērā o ngā pūtau wai whānui, ā, ko te ātete ā-roto o ngā pūtau polymer ā-whare ka iti iho i te 35mΩ, ka whakaiti i te whakamahinga-ake a te pākahiko, ka roa ake te wā tatari o ngā waea pūkoro, ā, ka taea te eke ki te taumata o ngā paerewa o te ao. He pai rawa atu tēnei momo pākahiko polymer lithium e tautoko ana i te iahiko tuku nui mō ngā tauira mana mamao, ā, koinei te mea tino whai hua hei whakakapi i ngā pākahiko NiMH.
