Pa ntchito zosiyanasiyana, mabatire amphamvu kwambiri akufunidwa kwambiri masiku ano. Mabatirewa ali ndi ntchito zambiri, kuphatikizapo mabatire a dzuwa, magalimoto amagetsi, ndi zosangalatsa. Mabatire a lead-acid anali okhawo omwe anali ndi mphamvu zambiri pamsika mpaka zaka zingapo zapitazo. Komabe, chikhumbo cha mabatire okhala ndi lithiamu chasintha kwambiri pamsika wamakono chifukwa cha ntchito zawo.

Batri ya lithiamu-ion ndi lithiamu Iron phosphate (LiFePO4Batri ndi yosiyana kwambiri ndi ena pankhaniyi. Anthu nthawi zambiri amafunsa za kusiyana pakati pa mabatire awiriwa chifukwa amachokera ku lithiamu.

Zotsatira zake, tifufuza mabatire awa mwatsatanetsatane munkhaniyi ndikukambirana momwe amasiyanirana. Mwa kuphunzira za momwe amagwirira ntchito pazinthu zosiyanasiyana, mudzapeza chidziwitso chochuluka cha batire yomwe ingakugwireni bwino. Popanda kuchedwa, tiyeni tiyambe:

Chifukwa chake Mabatire a LiFePO4 ndi abwino:

Opanga m'mafakitale osiyanasiyana amayang'ana lithiamu iron phosphate kuti agwiritse ntchito pamene chitetezo chili chofunikira. Kulimba kwa mankhwala ndi kutentha ndi khalidwe la lithiamu iron phosphate. M'malo otentha, batri iyi imasunga kuzizira kwake.

Sizimayakanso ngati sizikukonzedwa bwino panthawi ya kuchajidwa mwachangu komanso kutulutsa mpweya kapena pamene vuto la short circuit likuchitika. Chifukwa cha kukana kwa phosphate cathode ku kuyaka kapena kuphulika panthawi ya kuchajidwa kwambiri kapena kutenthedwa kwambiri komanso mphamvu ya batri yosunga kutentha kokhazikika, mabatire a lithiamu iron phosphate nthawi zambiri sakumana ndi kutentha koopsa.

Komabe, ubwino wa chitetezo cha lithiamu-ion batire ndi wochepa poyerekeza ndi wa lithiamu iron phosphate. Batireyi ikhoza kukhala yodalirika kwambiri chifukwa cha mphamvu zake zambiri, zomwe ndi vuto. Popeza batire ya lithiamu-ion imatha kutenthedwa ndi kutentha, imatenthedwa mwachangu ikadzachajidwa. Kuchotsedwa kwa batire pambuyo pake mutagwiritsa ntchito kapena kulephera kugwira ntchito ndi phindu lina la lithiamu iron phosphate pankhani ya chitetezo.

Mankhwala a lithiamu cobalt dioxide omwe amagwiritsidwa ntchito m'mabatire a lithiamu-ion amaonedwa kuti ndi oopsa chifukwa amatha kupangitsa anthu kukhala ndi vuto la ziwengo m'maso ndi pakhungu lawo. Akameza, amathanso kubweretsa mavuto aakulu azaumoyo. Chifukwa chake, mabatire a lithiamu-ion amafunika nkhawa zapadera zotayira. Komabe, opanga amatha kutaya lithiamu iron phosphate mosavuta chifukwa si poizoni.

Kuzama kwa kutulutsa kwa mabatire a lithiamu-ion kumayambira pa 80% mpaka 95%. Izi zikutanthauza kuti nthawi zonse muyenera kusiya mphamvu yochepera 5% mpaka 20% (chiwerengero chenicheni chimasiyana malinga ndi batire yeniyeni) mu batire. Kuzama kwa kutulutsa kwa mabatire a lithiamu iron phosphate (LiFeP04) kuli kwakukulu kwambiri pa 100%. Izi zikusonyeza kuti batire ikhoza kutulutsidwa kwathunthu popanda chiopsezo choiwononga. Batire ya lithiamu iron phosphate ndiyo yomwe imakonda kwambiri poyerekeza ndi kuzama kwa kutha.

Kodi vuto lalikulu la batri ya lithiamu-ion ndi liti?

Mtengo ndi kudalirika kwa makina osungira mphamvu, monga omwe amagwiritsidwa ntchito ngati magetsi owonjezera kapena kuchepetsa kusinthasintha kwa mphamvu zomwe zimapangidwa kuchokera ku magwero a mphamvu zongowonjezwdwanso, zimakhudzidwa kwambiri ndi nthawi yogwira ntchito ya mabatire. Komabe, mabatire a lithiamu-ion ali ndi zovuta zazikulu, kuphatikizapo kukalamba ndi chitetezo.

Mphamvu ya mabatire ndi maselo a lithiamu-ion ndi yotsika poyerekeza ndi ya mabatire a Lithium iron phosphate. Ayenera kusamala kuti asadzazidwe kwambiri kapena kutulutsidwa mopitirira muyeso. Kuphatikiza apo, ayenera kusunga mphamvu yamagetsi mkati mwa malire oyenera. Chifukwa chake, vuto limodzi la mabatire a lithiamu-ion ndikuti magetsi oteteza ayenera kuwonjezedwa kuti atsimikizidwe kuti akusungidwa mkati mwa malo awo otetezeka ogwirira ntchito.

Mwamwayi, ukadaulo wa digito wolumikizidwa ndi ma circuit umapangitsa kuti zikhale zosavuta kuyika izi mu batri kapena, ngati batri silingasinthidwe, zidazo. Mabatire a Li-ion angagwiritsidwe ntchito popanda ukatswiri wapadera chifukwa cha kuphatikiza ma circuitry oyang'anira mabatire. Batri ikadzala ndi chaji yokwanira, imatha kusungidwa pa chaji, ndipo chochaja chimadula mphamvu ku batri.

Mabatire a lithiamu-ion ali ndi njira zoyendetsera mabatire zomwe zimayang'anira mbali zosiyanasiyana za magwiridwe antchito awo. Dera loteteza limaletsa magetsi ambiri a selo iliyonse akamachaja chifukwa magetsi ambiri amatha kuvulaza maselo. Popeza mabatire nthawi zambiri amakhala ndi kulumikizana kamodzi kokha, nthawi zambiri amachaja motsatizana, zomwe zimawonjezera chiopsezo cha selo imodzi kulandira magetsi ambiri kuposa ofunikira chifukwa maselo osiyanasiyana angafunike magetsi osiyanasiyana.

Njira yoyendetsera mabatire imatsatiranso kutentha kwa selo kuti ipewe kutentha kwambiri. Mabatire ambiri amakhala ndi mphamvu yokwanira yochajira ndipo amaletsa kutulutsa mphamvu pakati pa 1°C ndi 2°C. Komabe, akachajira mofulumira, ena nthawi zina amatenthedwa pang'ono.

Mfundo yakuti mabatire a lithiamu ion amawonongeka pakapita nthawi ndi imodzi mwa zovuta zazikulu zowagwiritsa ntchito mu zipangizo zamagetsi. Izi zimadalira nthawi kapena kalendala, komanso zimatengera kuchuluka kwa mabatire omwe amatulutsa chaji. Nthawi zambiri, mabatire amatha kupirira ma cycle 500 mpaka 1000 okha asanayambe kutsika mphamvu zawo. Chiwerengerochi chikukwera pamene ukadaulo wa lithiamu-ion ukupitirira, koma ngati mabatirewo aphatikizidwa mumakina, angafunike kusinthidwa pakapita nthawi.

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

Lithium chitsulo phosphate (LiFePO4Mabatire a LiFePO4 ali ndi ubwino wambiri poyerekeza ndi mabatire a lithiamu-ion. Mabatirewa ali ndi mphamvu zambiri zotulutsa ndi kutchaja, amakhala nthawi yayitali, sakukonza, amakhala otetezeka kwambiri, komanso ndi opepuka, kungotchulapo zochepa. Ngakhale mabatire a LiFePO4 si omwe ali otsika mtengo kwambiri pamsika, ndi omwe amaika ndalama zambiri nthawi yayitali chifukwa cha moyo wawo wautali komanso kusakonza.

Mabatire a lithiamu iron phosphate (LiFePO4) akatuluka madzi okwana 80 peresenti, amatha kubwezeretsedwanso nthawi 5000 popanda kuwononga mphamvu. Nthawi yogwira ntchito ya mabatire a lithiamu iron phosphate (LiFePO4) ikhoza kuwonjezeka pang'onopang'ono.

Kuphatikiza apo, mabatirewa alibe mphamvu zokumbukira, ndipo mutha kuwasunga kwa nthawi yayitali chifukwa cha kuchepa kwa mphamvu zawo zotulutsa madzi (3% pamwezi). Chisamaliro chapadera chikufunika pa mabatire a lithiamu-ion. Ngati sichoncho, nthawi yawo yotsala idzachepa kwambiri.

Mabatire a lithiamu iron phosphate (LiFePO4) odzaza ndi mphamvu ya 100% ndi omwe angagwiritsidwe ntchito. Ndi abwino kwambiri pa ntchito zosiyanasiyana chifukwa cha mphamvu zawo zochapira ndi kutulutsa mphamvu mwachangu. Mphamvu imawonjezeka, ndipo kuchedwa kulikonse kumachepetsedwa chifukwa cha kuchapira mwachangu. Mphamvu imaperekedwa mwachangu ndi ma pulse currents amphamvu.

Yankho

Magetsi a dzuwa akhala akugulitsidwa chifukwa mabatire ndi othandiza kwambiri. Ndikoyenera kunena kuti njira yabwino yosungiramo mphamvu imangopangitsa kuti pakhale malo aukhondo, otetezeka, komanso ofunika kwambiri. Zipangizo zamagetsi a dzuwa zingapindule kwambiri pogwiritsa ntchito mabatire a lithiamu iron phosphate ndi lithiamu-ion.

Komabe,LiFePO4Mabatire ali ndi ubwino wambiri kwa ogula ndi ogulitsa. Kuyika ndalama m'malo opangira magetsi onyamulika pogwiritsa ntchito mabatire a LiFePO4 ndi chisankho chabwino kwambiri chifukwa cha magwiridwe antchito awo apamwamba, nthawi yayitali yosungira, komanso kuchepa kwa zotsatirapo zachilengedwe.
