LiFePO4 VS.Mabatire a Lithium-Ion-Momwe mungasankhire yomwe ili yabwino

Kwa ntchito zosiyanasiyana, mabatire apamwamba kwambiri akufunika kwambiri masiku ano.Mabatirewa ali ndi ntchito zambiri, kuphatikiza ma solar, galimoto yamagetsi, ndi mabatire osangalatsa.Mabatire a lead-acid anali okhawo omwe amasankha kuchuluka kwa batri pamsika mpaka zaka zingapo zapitazo.Chikhumbo cha mabatire a lithiamu chasintha kwambiri pamsika wamakono, ngakhale, chifukwa cha ntchito zawo.

Batire ya lithiamu-ion ndi lithiamu Iron phosphate (LiFePO4) batire imaonekera bwino pakati pa ena pankhaniyi.Anthu nthawi zambiri amafunsa za kusiyana kwa mabatire awiriwa chifukwa ndi opangidwa ndi lithiamu.

Zotsatira zake, tiwunika mabatire mozama muchigawochi ndikukambirana momwe amasiyanirana.Pophunzira za momwe amagwirira ntchito pazinthu zosiyanasiyana, mupeza chidziwitso chambiri chomwe batire ingagwire ntchito bwino kwa inu.Popanda kuchedwa, tiyeni tiyambe:

Chifukwa chiyani Mabatire a LiFePO4 ali bwino:

Opanga m'mafakitale osiyanasiyana amayang'ana ku lithiamu iron phosphate kuti agwiritse ntchito pomwe chitetezo ndichofunikira.Mankhwala abwino kwambiri komanso kukhazikika kwamafuta ndi katundu wa lithiamu iron phosphate.M'malo otentha, batire iyi imasunga kuziziritsa kwake.

Komanso siwopsereza pamene ikugwiritsidwa ntchito molakwika panthawi yolipiritsa mwachangu ndi kutulutsa kapena pakachitika zovuta zafupipafupi.Chifukwa cha kukana kwa phosphate cathode kuyaka kapena kuphulika panthawi yowonjezereka kapena kutenthedwa komanso kutha kwa batri kusunga kutentha kwabata, mabatire a lithiamu iron phosphate nthawi zambiri sakhala ndi kuthawa kwamafuta.

Komabe, mapindu achitetezo a lithiamu-ion batire chemistry sakhala wamkulu kuposa a lithiamu iron phosphate.Batire ikhoza kukhala yodalirika chifukwa cha kuchuluka kwa mphamvu zake, zomwe ndizovuta.Monga batire ya lithiamu-ion imatha kuthawa chifukwa cha kutentha, imatenthetsa mwachangu ndikuyitanitsa.Kuchotsedwa kwa batri pambuyo pa kugwiritsidwa ntchito kapena kusagwira ntchito ndi phindu lina la lithiamu iron phosphate ponena za chitetezo.

Mankhwala a lithiamu cobalt dioxide omwe amagwiritsidwa ntchito m'mabatire a lithiamu-ion amaonedwa kuti ndi owopsa chifukwa amatha kuwonetsa anthu kuti asavutike m'maso ndi pakhungu.Akamezedwa, angayambitsenso mavuto aakulu a thanzi.Zotsatira zake, mabatire a lithiamu-ion amafunikira kukhudzidwa kwapadera.Komabe, opanga amatha kutaya lithiamu iron phosphate mosavuta chifukwa alibe poizoni.

Kuzama kwa kutulutsa kwa mabatire a lithiamu-ion kumachokera ku 80% mpaka 95%.Izi zikutanthauza kuti nthawi zonse muyenera kusiya ndalama zosachepera 5% mpaka 20% (peresenti yeniyeni imasiyanasiyana kutengera batire yeniyeni) mu batri.Kuzama kwa mabatire a lithiamu iron phosphate (LiFeP04) ndikokwera modabwitsa pa 100%.Izi zikuwonetsa kuti batire ikhoza kutulutsidwa kwathunthu popanda chiopsezo choyiwononga.Battery ya lithiamu iron phosphate ndiyomwe imakonda kwambiri pakuzama kwa kuchepa.

Kodi choyipa chachikulu cha batire ya Lithium-ion ndi chiyani?

Mtengo ndi kudalirika kwa makina osungira mphamvu, monga omwe amagwiritsidwa ntchito ngati magetsi osunga zobwezeretsera kapena kuchepetsa kusinthasintha kwamagetsi opangidwa kuchokera kumagetsi ongowonjezedwanso, kumakhudzidwa kwambiri ndi moyo wogwira ntchito wa mabatire.Komabe, mabatire a lithiamu-ion ali ndi zovuta zazikulu, kuphatikizapo kukalamba ndi chitetezo.

Mphamvu zamabatire a lithiamu-ion ndi ma cell ndizotsika kuposa mabatire a Lithium iron phosphate.Ayenera kukhala osamala kuti asawalipiritse mochulukira ndi kutulutsidwa monyanyira.Kuonjezera apo, ayenera kusunga panopa mkati mwa malire ovomerezeka.Zotsatira zake, chotsalira chimodzi cha mabatire a lithiamu-ion ndikuti chitetezo chamagetsi chiyenera kuwonjezeredwa kuti zitsimikizire kuti zimasungidwa mkati mwa magawo awo otetezeka.

Mwamwayi, ukadaulo wophatikizika wa digito umapangitsa kuti zikhale zosavuta kuphatikiza izi mu batri kapena, ngati batire silingasinthike, zida.Mabatire a Li-ion atha kugwiritsidwa ntchito popanda ukadaulo wapadera chifukwa chophatikizidwa ndi kayendedwe ka batire.Batire ikadzakwana, imatha kusungidwa pa charger, ndipo charger imadula mphamvu ya batire.

Mabatire a Lithium-ion ali ndi makina opangira ma batri omwe amawunika momwe amagwirira ntchito.Dera lachitetezo limaletsa mphamvu yamagetsi yayikulu kwambiri ya cell iliyonse panthawi yolipira chifukwa ma voltage ochulukirapo amatha kuvulaza ma cell.Popeza mabatire nthawi zambiri amakhala ndi kulumikizana kumodzi kokha, nthawi zambiri amaperekedwa motsatizana, zomwe zimapangitsa kuti chiwopsezo cha cell imodzi ilandire voteji yoposa yofunikira chifukwa ma cell osiyanasiyana angafunike milingo yosiyana.

Njira yoyendetsera batire imasunganso kutentha kwa ma cell kuti apewe kutentha kwambiri.Mabatire ambiri amakhala ndi chiwongolero chachikulu komanso kuletsa kwapakati pa 1°C ndi 2°C.Komabe, pochajisa mofulumira, ena amafunda pang’ono.

Mfundo yakuti mabatire a lithiamu ion amawonongeka pakapita nthawi ndi chimodzi mwazovuta zazikulu zowagwiritsa ntchito pazida zogula.Izi zimatengera nthawi kapena kalendala, komanso zimatengera kuchuluka kwa ma charger omwe batire yadutsa.Nthawi zambiri, mabatire amatha kupitilira kutulutsa kwapakati pa 500 mpaka 1000 mphamvu yawo isanatsike.Nambalayi ikukwera pamene teknoloji ya lithiamu-ion ikupita patsogolo, koma ngati mabatire amangidwa m'makina, angafunikire kusinthidwa pakapita nthawi.

Kodi mungasankhe bwanji pakati pa mabatire a LiFePO4 ndi Lithium-ion?

Lithium iron phosphate (LiFePO4) mabatire ali ndi zabwino zambiri poyerekeza ndi mabatire a lithiamu-ion.Kutulutsa bwino komanso kuthirira mwachangu, moyo wautali, kusakonza, chitetezo chambiri, komanso kupepuka, kungotchulapo zochepa.Ngakhale mabatire a LiFePO4 sali m'gulu lotsika mtengo kwambiri pamsika, ndi ndalama zomwe zimafunikira nthawi yayitali chifukwa cha moyo wawo wautali komanso kusowa kosamalira.

Pakuzama kwa 80 peresenti, mabatire a lithiamu iron phosphate amatha kuyitanidwanso nthawi 5000 popanda kusokoneza mphamvu.Moyo wogwira ntchito wa mabatire a lithiamu iron phosphate (LiFePO4) ukhoza kuchulukitsidwa mosasamala.

Kuonjezera apo, mabatire alibe zotsatira zokumbukira, ndipo mukhoza kuwasunga kwa nthawi yaitali chifukwa cha kuchepa kwawo (3% pamwezi).Chisamaliro chapadera chimafunikira mabatire a lithiamu-ion.Ngati sichoncho, nthawi ya moyo wawo idzacheperachepera.

100% kuchuluka kwa mabatire a lithiamu iron phosphate (LiFePO4) amatha kugwiritsidwa ntchito.Amakhalanso angwiro pazogwiritsa ntchito zosiyanasiyana chifukwa cha kuchuluka kwawo mwachangu komanso kutulutsa kwawo.Kuchita bwino kumawonjezeka, ndipo kuchedwa kulikonse kumachepetsedwa ndi kulipiritsa mwachangu.Mphamvu zimaperekedwa mothamanga kwambiri ndi mafunde othamanga kwambiri.

Yankho

Magetsi a solar apirira pamsika chifukwa mabatire ndi opambana.Ndizomveka kunena kuti njira yabwino yosungiramo mphamvu yosungiramo mphamvu idzangobweretsa malo aukhondo, otetezeka, ndi ofunika kwambiri.Zipangizo zamagetsi zamagetsi zimatha kupindula kwambiri pogwiritsa ntchito lithiamu iron phosphate ndi mabatire a lithiamu-ion.

Komabe,LiFePO4mabatire ali ndi zopindulitsa zambiri kwa onse ogula ndi ogulitsa.Kuyika ndalama m'malo onyamula magetsi okhala ndi mabatire a LiFePO4 ndichisankho chabwino kwambiri chifukwa chakuchita bwino kwambiri, kukhala ndi nthawi yayitali, komanso kuchepa kwachilengedwe.
