Lithium Umzi-mveliso webhetri

Yintoni iLithium?

I-Lithium yinto yekhemikhali esetyenziswa kuzo zonke iintlobo zeebhetri, kubandakanywa zombini umgangatho kunye nokutshajwa kwakhona. Ibhetri ye-lithium-ion lolona hlobo ludumileyo lwebhetri olusetyenziswayo namhlanje.

Ukwenza iibhetri zeLithium Ion

Inyathelo lokuqala ekwenzeni ibhetri ye-lithium ion kukudala i-anode, eyenziwa ngokuqhelekileyo kwikhabhoni. Izinto ze-anode kufuneka zicutshungulwe kwaye zihlanjululwe ukususa nayiphi na i-nitrogen, eya kubangela ukuba izinto ze-anode zigqithise ngokugqithiswa ngamaqondo aphezulu. Isinyathelo esilandelayo sidala i-cathode kwaye siyifake kwi-anode nge-conductor yensimbi. Lo mqhubi wentsimbi udla ngokuza ngocingo lobhedu okanye lwe-aluminium.

Ukuvelisa iibhetri ze-lithium ion kunokuba yinkqubo eyingozi ngenxa yokusetyenziswa kweekhemikhali ezifana ne-manganese dioxide (MnO2). IManganese diokside ikhupha umsi oyityhefu xa ifudunyezwa kumaqondo obushushu aphezulu. Nangona le khemikhali iyadingeka kwiibhetri ze-lithium ion, ayikwazi ukudibana nomoya okanye ukufuma ngenxa yokuba inokukhupha igesi enetyhefu (khumbula indlela endiyikhankanye ngayo ngaphambili?). Ukunqanda oku, abavelisi banezabo izicwangciso zokuphatha ezi gesi ngexesha lemveliso njengokugquma ii-electrode ngomphunga wamanzi njengokhuselo ekutyhilekeni kweoksijini kunye nehydrogen.

Abavelisi baya kubeka kwakhona isahluli phakathi kwee-electrode ezimbini, ezithintela iisekethe ezimfutshane ngokuvumela ii-ion ukuba zidlule kodwa zivala ii-electron ekwenzeni oko.

Enye inxalenye ebalulekileyo yokuvelisa iibhetri ze-lithium ion yongeza i-electrolyte engamanzi phakathi kwee-electrode ezimbini. Le electrolyte engamanzi inceda ukuqhuba ii-ion kwaye ivumela ukuhamba kombane phakathi kwee-electrode zombini ngelixa ithintela enye i-electrode ekuchukumiseni enye, enokubangela isekethe emfutshane okanye umlilo. Kuphela xa onke la manyathelo sele egqityiwe siyakwazi ukwenza imveliso yethu yokugqibela: ibhetri ye-lithium ion.

Iibhetri zeLithium Ion zinika amandla izinto ezininzi esizisebenzisa yonke imihla. Kwaye ngokwanda kokuthandwa kwazo, ziya zisanda iifektri ezivelisa izixhobo zebhetri kunye neemveliso. Njengalo naliphi na ishishini, kukho iingozi kwimveliso kunye nokulahlwa. Siyathemba ukuba eli nqaku belinolwazi, kwaye ngoku unokuqonda okungcono kushishino lwebhetri yeLithium.
