Iibhetri ze-Li-ion

ngo kim Ukuhlaziywa: Julayi 9, 2022

Iibhetri ze-Li-ion ziibhetri ezinokutshajwa kwakhona ezine-lithium ion. Zisetyenziswa kuyo yonke into ukusuka kwiiselfowuni ukuya kwiimoto. Kodwa zisebenza njani?

Iibhetri ze-Li-ion zisebenzisa inkqubo yokudibanisa ukugcina amandla. Le nkqubo ibandakanya i-lithium ion ehamba phakathi kwe-cathode kunye ne-anode ngaphakathi kwebhetri. Nini ukuhlawula, ii-ion zihamba ukusuka kwi-anode ukuya kwi-cathode, kwaye xa zikhupha, zihamba kwelinye icala.

Kodwa oko kushwankathela nje. Makhe sijonge yonke into ngokweenkcukacha ngakumbi.

Yintoni ibhetri yeLithium-Ion?

Iibhetri zeLithium-ion zikhona kuyo yonke indawo kule mihla! Banika amandla iifowuni zethu, laptops, izithuthi zombane, kunye nokunye. Kodwa ziyintoni kanye kanye? Makhe sihlolisise ngakumbi!

I siseko

Iibhetri zeLithium-ion zenziwe ngeseli enye okanye ngaphezulu, ibhodi yesekethe ekhuselayo, kunye nezinye izinto ezimbalwa:

• Electrodes: Iziphelo ezichajiwe kakuhle nezichajiweyo zeseli. Incanyathiselwe kubaqokeleli bangoku.
• Inode: I-electrode engeyiyo.
• Electrolyte: Lulwelo okanye ijeli ehambisa umbane.
• Abaqokeleli bangoku: Iifoyile zokuqhuba kwi-electrode nganye yebhetri edityaniswe kwiitheminali zeseli. Ezi theminali zisasaza umsinga wombane phakathi kwebhetri, isixhobo, kunye nomthombo wamandla onika amandla ibhetri.
• Isahluli: Ifilimu yepolymeric ene-porous eyahlula i-electrodes ngelixa ivumela ukutshintshiselwa kwe-lithium ion ukusuka kwelinye icala ukuya kwelinye.

Ingaba isebenza kanjani

Xa usebenzisa isixhobo esiqhutywa yibhetri ye-lithium-ion, ii-ion ze-lithium zijikeleza ngaphakathi kwebhetri phakathi kwe-anode kunye ne-cathode. Ngelo xesha, ii-electron zijikeleza kwisekethe yangaphandle. Le ntshukumo yeeyoni kunye nee-electron yiyo eyenza umsinga wombane onika amandla isixhobo sakho.

Xa ibhetri ikhupha, i-anode ikhupha i-lithium ion kwi-cathode, ivelisa ukuhamba kwee-electron ezinceda ukunika amandla isixhobo sakho. Xa ibhetri ihlawula, kwenzeka okuchaseneyo: i-lithium ion ikhutshwa yi-cathode kwaye ifunyenwe yi-anode.

Unokuzifumana Phi?

Iibhetri zeLithium-ion zikhona kuyo yonke indawo kule mihla! Ungazifumana kwiifowuni, iilaptops, iimoto zombane, nokunye. Ke kwixesha elizayo xa usebenzisa esinye sezixhobo zakho ozithandayo, khumbula nje ukuba iqhutywa yibhetri ye-lithium-ion!

Imbali enomdla yebhetri yeLithium-Ion

Imizamo yokuqala yeNASA

Emva ngeminyaka yee-'60s, iNASA yayisele izama ukwenza ibhetri ye-Li-ion egcwalisekayo. Baphuhlise ibhetri yeCuF2/Li, kodwa ayizange isebenze kakuhle.

Impumelelo kaM. Stanley Whittingham

Kwi-1974, i-chemist yaseBrithani uM. Stanley Whittingham yenza impumelelo xa isebenzisa i-titanium disulfide (TiS2) njengento ye-cathode. Oku kwakunesakhiwo esine-layer esinokuthatha i-lithium ion ngaphandle kokutshintsha isakhiwo sayo se-crystal. I-Exxon yazama ukuthengisa ibhetri, kodwa yayibiza kakhulu kwaye inzima.

Iibhetri zeLi-Ion Vs Lead Acid

Iibhetri ze-lead acid zitshiphu kuneebhetri ze-lithium-ion, kodwa azisebenzi ngokunjalo. Iibhetri ze-lead ze-asidi zinokuthatha ukuya kwiiyure ezili-10 ukutshaja, ngelixa iibhetri ze-lithium ion zinokutshaja nje ngemizuzu embalwa. Kungenxa yokuba iibhetri ze-lithium ion zinokwamkela isantya esikhawulezayo sangoku, ukutshaja ngokukhawuleza kuneebhetri zeasidi yelothe. Ke ukuba ujonge ibhetri ehlawulisa ngokukhawuleza nangokufanelekileyo, i-lithium ion yindlela yokuhamba. Kodwa ukuba unohlahlo lwabiwo-mali, iasidi ekhokelayo lolona khetho lufikelelekayo.

FAQ

Ngaba ibhetri ye-Li-ion iyafana ne-lithium?

Hayi, iibhetri ze-Li-ion kunye neebhetri ze-lithium azifani! Iibhetri zeLithium ziiseli eziphambili, okuthetha ukuba aziphinde zitshajwe. Ke, xa uzisebenzisa, ziphelile. Ngakolunye uhlangothi, iibhetri ze-Li-ion ziiseli zesibini, oku kuthetha ukuba zinokuphinda zitshajwe kwaye zisetyenziswe ngokuphindaphindiweyo. Ngaphezu koko, iibhetri ze-Li-ion zibiza kakhulu kwaye zithatha ixesha elide ukuzenza kuneebhetri ze-lithium. Ke, ukuba ujonge ibhetri enokuthi itshajwe, iLi-ion yindlela omawuhambe ngayo. Kodwa ukuba ufuna into enexabiso eliphantsi kwaye ihlala ixesha elide, i-lithium yeyona nto ibhetele yokubheja kwakho.

Ngaba ufuna itshaja ekhethekileyo yeebhetri ze-lithium?

Hayi, awudingi tshaja ekhethekileyo yeebhetri ze-lithium! Ngeebhetri ze-iTechworld lithium, akufuneki uphucule inkqubo yakho yokutshaja kwaye uchithe imali eyongezelelweyo. Ekuphela kwento oyifunayo yitshaja yakho ekhoyo yeasidi kwaye ulungile ukuba uhambe. Iibhetri zethu ze-lithium zineNkqubo ekhethekileyo yoLawulo lwebhetri (BMS) eqinisekisa ukuba ibhetri yakho ihlawulisa ngokuchanekileyo kunye netshaja yakho ekhoyo.
Itshaja ekukuphela kwayo esingakukhuthaziyo ukuyisebenzisa yenzelwe iibhetri zekhalsiyam. Kungenxa yokuba igalelo lombane lidla ngokuba phezulu kunoko kucetyiswa kwiibhetri zomjikelezo onzulu we-lithium. Kodwa ungakhathazeki, ukuba usebenzisa ngempazamo itshaja yekhalsiyam, iBMS iya kubona amandla ombane aphezulu kwaye ingene kwimo ekhuselekileyo, ikhusela ibhetri yakho kuwo nawuphi na umonakalo. Ngoko ke musa ukophula ibhanki ngokuthenga itshaja ekhethekileyo – sebenzisa nje ekhoyo kwaye uya kusekwa!

Bude kangakanani ubomi bebhetri ye-lithium-ion?

Iibhetri zeLithium-ion zingamandla emva kwezixhobo zakho zemihla ngemihla. Kodwa zihlala ixesha elingakanani? Ewe, i-avareji yebhetri ye-lithium-ion kufuneka ihlale phakathi kwe-300 kunye ne-500 yentlawulo / imijikelezo yokukhupha. Oku kufana nokutshaja ifowuni yakho kanye ngosuku ngaphezu konyaka! Kwaye, akufuneki ube nexhala malunga nemiba yememori njengoko ubuqhele ukwenza. Gcina nje ibhetri yakho ivaliwe kwaye ipholile kwaye uya kulungela ukuhamba. Ke, ukuba uyayikhathalela, ibhetri yakho ye-lithium-ion kufuneka ikugcine ixesha elide.

Yintoni eyona nto ingalunganga yebhetri ye-Li-ion?

Elona cala lisezantsi leebhetri zeLi-ion lixabiso lazo. Zimalunga ne-40% zibiza ngaphezulu kwe-Ni-Cd, ke ukuba ukuhlahlo lwabiwo-mali, unokufuna ukujonga kwenye indawo. Ngaphezu koko, baqhele ukuguga, oku kuthetha ukuba banokuphulukana namandla kwaye basilele emva kweminyaka embalwa. Akukho mntu enexesha lalo nto! Ke ukuba uza kutyala imali kwi-Li-ion, qiniseka ukuba uyalwenza uphando lwakho kwaye ufumane eyona bhangi yakho ilungileyo.

isiphelo

Ukuqukumbela, iibhetri ze-Li-ion zibuchwephesha obuguqukayo obunika amandla izixhobo zethu zemihla ngemihla, ukusuka kwiifowuni eziphathwayo ukuya kwizithuthi zombane. Ngolwazi oluchanekileyo, ezi bhetri zinokusetyenziswa ngokukhuselekileyo nangempumelelo, ngoko musani ukoyika ukuthatha ijusi kwaye uhlolisise ihlabathi leebhetri ze-Li-ion!
