I-Li-ion ibhethri elingalungiswa kahle, inzuzo amanye amakhemikhali amaningi angakwazi ukuyifuna.Ibhethri ayinayo inkumbulo futhi ayidingi ukujima (ukuyikhipha ngamabomu ngokugcwele) ukuyigcina isesimweni esihle.Ukuzikhipha ngokwakho kungaphansi kwengxenye yamasistimu asekelwe ku-nickel futhi lokhu kusiza ukusetshenziswa kwegeji likaphethiloli.Amandla kagesi kamakhalekhukhwini angu-3.60V anganika amandla omakhalekhukhwini ngokuqondile, amaphilisi namakhamera edijithali, anikeze ukwenza lula nokunciphisa izindleko ngemiklamo enamaseli amaningi.Izithiyo ziyisidingo samasekhethi okuvikela ukuvimbela ukuhlukumeza, kanye nenani eliphezulu.

Ibhethri ye-lithium-ion yoqobo yakwaSony yasebenzisa i-coke njenge-anode (umkhiqizo wamalahle).Kusukela ngo-1997, iningi labakhiqizi be-Li ion, okuhlanganisa no-Sony, bashintshele ku-graphite ukuze bathole ijika eliyisicaba.I-graphite iwuhlobo lwekhabhoni olunokuqina komjikelezo wesikhathi eside futhi isetshenziswa kumapensela omthofu.Yikhabhoni ejwayeleke kakhulu, elandelwa amakhabhoni aqinile nathambile.Amakhabhoni e-Nanotube awakakatholi ukusetshenziswa kwezentengiselwano ku-Li-ion njengoba evame ukuthandela futhi athinte ukusebenza.Into yesikhathi esizayo ethembisa ukuthuthukisa ukusebenza kwe-Li-ion i-graphene.
Umfanekiso wesi-2 ubonisa ijika lokukhishwa kwe-voltage ye-Li-ion yesimanje ene-graphite anode kanye nenguqulo yokuqala ye-coke.
Kuzanywe izithasiselo eziningana, okuhlanganisa nama-alloys asekelwe ku-silicon, ukuthuthukisa ukusebenza kwe-graphite anode.Kuthatha ama-athomu e-carbon (graphite) ayisithupha ukubopha i-lithium ion eyodwa;i-athomu ye-silicon eyodwa ingabophezela kuma-ion e-lithium amane.Lokhu kusho ukuthi i-silicon anode ngokwethiyori ingagcina amandla angaphezu kwe-10 amandla egraphite, kodwa ukunwetshwa kwe-anode ngesikhathi sokushaja kuyinkinga.Ngakho-ke i-silicone anode ehlanzekile ayisebenzi futhi amaphesenti angu-3-5 kuphela e-silicon ngokuvamile afakwa ku-anode ye-silicon-based ukuze kuzuzwe impilo yomjikelezo omuhle.
Ukusebenzisa i-lithium-titanate eyakhiwe nge-nano njengesengezo se-anode kukhombisa ukuphila komjikelezo othembisayo, amandla amahle omthwalo, ukusebenza okuhle kakhulu kwezinga lokushisa eliphansi nokuphepha okuphakeme, kodwa amandla athile aphansi futhi izindleko ziphezulu.
Ukuhlola nge-cathode kanye nokokusebenza kwe-anode kuvumela abakhiqizi ukuthi baqinise izimfanelo zangaphakathi, kodwa isithuthukisi esisodwa singalimaza esinye.Okubizwa ngokuthi “Ingqamuzana Lamandla” kuthuthukisa amandla athile (amandla) ukuze kuzuzwe izikhathi zokusebenza ezinde kodwa ngamandla athile aphansi;i-“Power Cell” inikeza amandla akhethekile akhethekile kodwa ngomthamo ophansi.I-"Hybrid Cell" iwukuvumelana futhi inikeza okuncane kwakho kokubili.
Abakhiqizi bangathola amandla athile aphezulu kanye nezindleko eziphansi kalula ngokungeza i-nickel esikhundleni se-cobalt ebiza kakhulu, kodwa lokhu kwenza iseli lingazinzi.Nakuba inkampani eqalayo ingase igxile emandleni athile aphezulu kanye nenani eliphansi ukuze yamukeleke ngokushesha emakethe, ukuphepha nokuhlala isikhathi eside akunakubekwa engcupheni.Abakhiqizi abahloniphekile babeka ubuqotho obuphezulu ekuphepheni nasekuphileni isikhathi eside.
Amabhethri amaningi e-Li-ion ahlanganyela ngomklamo ofanayo ohlanganisa i-metal oxide positive electrode (cathode) embozwe kumqoqi wamanje we-aluminium, i-electrode eyinegethivu (i-anode) eyenziwe nge-carbon/graphite ehuqwe kumqoqi wamanje wethusi, isihlukanisi kanye ne-electrolyte. eyenziwe ngosawoti we-lithium ku-solvent ephilayo.Ulwazi olwengeziwe, pls hamba ne-teda battery.com.
Ithebula lesi-3 lifingqa izinzuzo nemikhawulo ye-Li-ion.
