Baytariyada Li-ion ayaa ku dhawaad meel walba yaal.Waxa loo isticmaalaa codsiyada mobaylada iyo laptop-yada ilaa baabuurta isku-dhafka ah iyo kuwa korontada ku shaqeeya.Batariyada lithium-ion waxay sidoo kale caan ku yihiin codsiyada baaxadda leh sida Supplies Power Aan Kala Goyn karin (UPSs) iyo Nidaamyada Kaydinta Tamarta Tamarta ee Joogta ah (BESSs).
Batarigu waa aalad ka kooban hal ama in ka badan unugyo kiimikaad oo koronto leh oo leh xiriiryo dibadeed oo loogu talagalay tamarta qalabka korontada.Marka batarigu uu bixiyo awood koronto, terminalkiisa togan waa cathode, terminalkiisa taban waa anode.Terminal-ka taban ee calaamadsan waa isha elektarooniga ah ee ku qulquli doona wareegga korantada ee dibadda ilaa terminalka togan.
Marka batteriga lagu xiro culeys koronto oo dibadda ah, falcelinta redox (dhimista-oxidation) waxay u beddeshaa falcelinta tamarta sare ee tamarta hoose, farqiga tamarta xorta ah waxaa loo geeyaa wareegga dibadda sida tamar koronto.Taariikh ahaan ereyga "batteri" wuxuu si gaar ah u tilmaamayaa qalab ka kooban unugyo badan;si kastaba ha ahaatee, isticmaalku waxa uu u xuubsiibtay in lagu daro qalab ka kooban hal unug.
Sidee buu u shaqeeyaa baytariyada lithium-ion?
Inta badan baytariyada Li-ion waxay wadaagaan naqshad la mid ah oo ka kooban bir oxide positive electrode (cathode) oo lagu dahaadhay ururiyaha aluminium ee hadda jira, electrode taban (anode) oo laga sameeyay kaarboon/graphite oo lagu dahaadhay ururiyaha hadda jira ee naxaasta ah, kala-soocida iyo electrolyte ka samaysan cusbada lithium ee dareere organic ah.
Inta uu batarigu sii daynaayo oo uu bixinayo koronto, electrolyte-ku waxa uu si fiican u dallacay ion lithium ion ka anode ilaa cathode iyo dhanka kale iyada oo loo marayo kala-soocida.Dhaqdhaqaaqa ions lithium-ku wuxuu abuuraa elektaroono bilaash ah anode kaas oo abuura lacag ururiyaha hadda jira.Dabadeed socodka korantada ayaa ka soo qulqulaya ururiyaha hadda socda iyada oo loo marayo qalab ku shaqaynaya (taleefanka gacanta, kumbuyuutarka, iwm.) una gudbaya kuwa hadda taban.Kala soocida ayaa xannibaysa socodka elektarooniga ee gudaha batteriga.
Inta lagu jiro dallacaadda , isha koronto ee dibadda ah (wareegga dallacaadda) ayaa quseysa koronto-dhaaf ah (voltage ka sarreeya inta uu batarigu soo saaro, ee isla polarity), ku qasbaya dallacaadda in ay ku dhex socoto batteriga laga bilaabo togan ilaa korantada taban, ie jihada danbe ee qulqulka dareeraha ee xaaladaha caadiga ah.ion-yada lithium-ka ayaa markaa ka guura dhinaca togan una guura electrode taban, halkaas oo ay ku dhex milmaan walxaha korantada dabada ah ee habka loo yaqaan inter-calation.
