Zisebenza njani iibhetri zeLithium

I-Li-ion yibhetri yogcino oluphantsi, iadvanteji leyo uninzi lwezinye iikhemistri ezingenakubango.Ibhetri ayinankumbulo kwaye ayifuni ukuzilolonga (ukuyikhupha ngabom ngokupheleleyo) ukuyigcina ikwimo entle.Ukuzikhupha kungaphantsi kwesiqingatha seenkqubo ezisekelwe kwi-nickel kwaye oku kunceda ukusetyenziswa kwe-fuel gauge.I-voltage yeselula ebizwa ngokuba yi-3.60V inokunika amandla ngokuthe ngqo iifowuni eziphathwayo, iipilisi kunye neekhamera zedijithali, ezinikezela ngokulula kunye nokunciphisa iindleko kwiiseli ezininzi.Iintsilelo ziyimfuneko yeesekethe zokukhusela ukukhusela ukuxhatshazwa, kunye nexabiso eliphezulu.

Ibhetri yelithium-ion yoqobo yakwaSony isebenzise icoke njenge anode (imveliso yamalahle).Ukusukela ngo-1997, uninzi lwabavelisi be-Li ion, kubandakanya i-Sony, batshintshele kwigraphite ukuze bafumane igophe elithambileyo lokukhupha.Igraphite luhlobo lwekhabhoni enozinzo lomjikelo wexesha elide kwaye isetyenziswa kwiipensile zokukhokela.Yeyona nto ixhaphakileyo yekhabhoni, ilandelwa ziikhabhoni ezinzima nezithambileyo.Iikhabhoni zeNanotube azikafumani ukusetyenziswa kwezorhwebo kwi-Li-ion njengoko zithande ukubopha kwaye zichaphazele ukusebenza.Izinto ezizayo ezithembisa ukuphucula ukusebenza kweLi-ion yigraphene.

Umzobo we-2 ubonisa ijika lokukhupha i-voltage ye-Li-ion yanamhlanje ene-graphite anode kunye ne-coke version yokuqala.

Izongezo ezininzi zizanyiwe, kubandakanywa i-silicon-based alloys, ukuphucula ukusebenza kwe-graphite anode.Kuthatha i-athomu ezintandathu ze-carbon (graphite) ukubopha kwi-ion ye-lithium enye;iathom ye-silicon enye inokubophelela kwii-ion ze-lithium ezine.Oku kuthetha ukuba i-silicon anode inokugcina ithiyori ngaphezulu kwe-10 amandla egraphite, kodwa ukwandiswa kwe-anode ngexesha lokutshaja kuyingxaki.I-silicone i-anode ecocekileyo ke ayisebenzi kwaye kuphela i-3-5 ipesenti ye-silicon yongezwa kwi-anode ye-silicon-based ukufezekisa ubomi bomjikelezo omhle.

Ukusebenzisa i-nano-structured lithium-titanate njenge-anode additive ibonisa ubomi bomjikelezo othembisayo, amandla omthwalo omhle, ukusebenza kakuhle kweqondo lokushisa eliphantsi kunye nokhuseleko oluphezulu, kodwa amandla athile aphantsi kwaye ixabiso liphezulu.

Ukuzama nge-cathode kunye ne-anode imathiriyeli ivumela abavelisi ukuba bomeleze iimpawu zangaphakathi, kodwa isixhasi esinye sinokubeka esichengeni esinye.Oko kubizwa ngokuba yi-“Energy Cell” ikhulisa amandla athile (umthamo) wokuphumeza amaxesha okusebenza amade kodwa kumandla athile asezantsi;i-“Power Cell” inika amandla akhethekileyo kodwa kumthamo ophantsi."I-Hybrid Cell" yi-compromise kwaye inikezela kancinci kuzo zombini.

Abavelisi banokufumana amandla athile aphezulu kunye neendleko eziphantsi ngokulula ngokongeza i-nickel endaweni ye-cobalt ebiza kakhulu, kodwa oku kwenza iseli ingazinzi.Ngelixa inkampani eqalayo inokugxila kumandla athile aphezulu kunye nexabiso eliphantsi lokufumana ukwamkelwa ngokukhawuleza kwentengiso, ukhuseleko kunye nokuqina akunakuchaphazeleka.Abavelisi abahloniphekileyo babeka ingqibelelo ephezulu kukhuseleko kunye nokuphila ixesha elide.

Uninzi lweebhetri ze-Li-ion zabelana ngoyilo olufanayo olubandakanya i-metal oxide positive electrode (i-cathode) egqunywe kumqokeleli wangoku we-aluminium, i-electrode engalunganga (i-anode) eyenziwe kwikhabhoni / igraphite eqatywe kumqokeleli wangoku wobhedu, isahluli kunye ne-electrolyte. eyenziwe ngetyuwa ye-lithium kwi-solvent ephilayo.Ulwazi oluthe kratya, pls yiya ne teda battery.com.
