Waa maxay iska caabbinta gudaha ee baytariga lithium?
Marka uu hadda ku dhex qulqulo batteriga gudihiisa, waxa uu la kulmaa iska caabin, taas oo keenaysa hoos u dhac ku yimaadda tamarta shaqaynaysa baytariga. Iska caabintan waxa loo yaqaan caabbinta gudaha batteriga. Sababtoo ah iska caabbinta gudaha batteriga, danabku waa uu ka hooseeyaa xoogga korantada oo furan - danab wareega inta lagu jiro sii daynta. Inta lagu jiro dallacaadda, danabku terminalku wuu ka sarreeyaa xoogga korantada oo furan - danab wareega. Iska caabbinta gudaha ee baytarigu waa halbeeg aad muhiim u ah ilaha tamarta kiimikaad. Waxay si toos ah u saamaysaa tamarta shaqaynaysa batteriga, hadda shaqaynaysa, tamarta wax soo saarka, iyo awoodda. Ilaha awoodda kiimikaad ee la taaban karo, hoos u dhigista iska caabbinta gudaha, ayaa ka sii fiican.
Iska caabbinta baytarigu ma aha mid joogto ah; way kala duwan tahay inta lagu jiro dareeraha iyadoo ku xiran halabuurka walxaha firfircoon, feejignaanta elektrolytka, heerkulka batteriga, iyo wakhtiga dheecaanka. Iska caabbinta gudaha batteriga waxaa ka mid ah iska caabinta gudaha ohmic (R₀) iyo iska caabbinta gudaha ee polarization (Rf) oo ay soo bandhigaan korantada inta lagu jiro falcelinta korantada. Isu geynta labadan waxaa lagu magacaabaa caabbinta guud ee baytariga (Rw).
Iska caabbinta gudaha Ohmic waxay inta badan ka kooban tahay iska caabbinta gudaha ee qalabka elektiroonigga ah, electrolyte, kala-soocida, iyo iska caabbinta xiriirka ee qaybaha kala duwan. Waxa ay la xidhiidhaa cabbirka batteriga, qaab dhismeedka, habka samaynta koroodhyada (tusaale, koollada -nooca iyo tubular electrodes ee ku jira rasaasta rasaasta - baytariyada aysiidhka, iyo sanduuqa{{5}nooca iyo korantada sintered ee baytariyada alkaline), iyo adkaynta isku xidhka. Iska caabinta gudaha Ohmic waxay adeecdaa sharciga Ohm.
Polarization-ka iska caabinta gudaha waxaa loola jeedaa iska caabbinta gudaha ee ay keento polarization ee u dhexeeya korantada togan iyo kuwa taban ee isha tamarta kiimikada inta lagu jiro falcelinta korantada. Waa wadarta iska caabbinta ay keento polarization electrochemical and focus
polarization.
Polarization caabbinta gudaha waxay la xiriirtaa dabeecadda walxaha firfircoon, qaab dhismeedka korantada, iyo habka wax soo saarka batteriga, gaar ahaan si dhow ula xiriira xaaladaha shaqada ee batteriga; qulqulka hadda jira iyo heerkulka ayaa leh saameyn weyn. Inta lagu jiro dheecaanka cufnaanta sare ee hadda, polarization korantada labadaba iyo polarization-ka xoojinta labaduba way kordhaan, taas oo suurtogal ah xitaa inay keento shucaaca korantada taban, sidaas darteed kordhinta caabbinta gudaha ee polarization. Heerkulka hooseeya ayaa si xun u saameeya polarization electrochemical iyo fidinta ion; sidaa awgeed, iska caabbinta gudaha ee batteriga batteriga ayaa sidoo kale ku kordha xaaladaha kulaylka hooseeya{2}. Sidaa darteed, iska caabbinta polarization maaha mid joogto ah, laakiin waxay isbeddelaysaa heerka dheecaanka, heerkulka iyo xaaladaha kale.
Tibaaxaha falanqaynta ee caabbinta gudaha ee baytariga waa sida soo socota:
Qaaciddada, bE (iₐ,τ,C) Iₐ⁻¹- Iska caabbinta gudaha ee baytarigu;
b{{0}Isku dhafka kala duwanaanshaha danab ka baxa batteriga marka loo eego tamarta tamarta E ee hoos timaada xaaladaha awooda marka batteriga lagu dalaco oo laga saaro Iₐ hadda;
Rₑₗ(τ,C)-Ka caabbinta elektrolytka;
Rₑ(C) - Iska caabbinta korantada Iska caabinta elektrolytka Rₑₗ iyo iska caabbinta korantada Rₑ waxay u dhigmaan awoodda degdegga ah ee batteriga;
iₐ, τ, C-Ku dallaca batteriga iyo soo daynta hadda, heerkulka, iyo heerka awoodda wakhtigaas.
Iska caabbinta baytarigu waa mid yar oo inta badan waa dayac marka ay jiraan xaalado badan oo hawlgal ah. Si kastaba ha ahaatee, baytariyada korantada ee baabuurta korontada inta badan waxay ku shaqeeyaan xaaladaha sare ee hadda jira iyo kuwa qoto dheer, taasoo keentay hoos u dhac weyn oo koronto ah oo ay keento iska caabin gudaha ah. Xaaladdan oo kale, saameynta iska caabbinta gudaha ee wareegga oo dhan lama iska indho tiri karo.
