Kufanele ngabe uzwile ngebhethri ye-Lithium!Kungokwesigaba samabhethri ayisisekelo ahlanganisa i-lithium eyinsimbi.I-metallic lithium isebenza njenge-anode ngenxa yokuthi leli bhethri laziwa nangokuthi ibhethri le-lithium-metal.Uyazi ukuthi yini eyenza ahluke kwezinye izinhlobo zamabhethri?
Noma nini lapho ibhethri ye-lithium iba manzi, ukusabela okwenzekayo kuyamangaza.I-lithium yakha i-lithium hydroxide kanye ne-hydrogen evutha kakhulu.Isixazululo esakhiwe siyi-alkali ngempela ngokwemvelo.Ukusabela kuhlala isikhathi eside uma kuqhathaniswa nokusabela okwenzeka phakathi kwe-sodium namanzi.
Ngezinjongo zokuphepha, akunconywa ukugcinaamabhethri e-lithiumamazinga okushisa aseduze.Kufanele zigcinwe kude nokukhanya kwelanga okuqondile, ama-laptops nama-radiator.Lawa mabhethri azwela kakhulu ngokwemvelo ngenxa yalokho akumele agcinwe ezindaweni lapho kunamathuba aphezulu okuhlangabezana nomonakalo.
Ingabe uhlela ukwenza isilingo ngokucwilisa ibhethri ye-lithium emanzini?Kungcono ukungakwenzi lokho ngephutha njengoba kungase kubulale kakhulu.Ibhethri ngemva kokucwiliswa emanzini liphumela ekuvuzeni okuphezulu kwamakhemikhali ayingozi.Njengoba amanzi engena ngaphakathi kwebhethri, amakhemikhali ayahlangana akhiphe isakhi esiyingozi.
I-compound ibulala kakhulu ngokwezempilo.Kungase kubangele ukushiswa kwesikhumba ekuthinteni.Futhi, ibhethri lilimala kabi.
Uma ibhethri lakho le-lithium libhobozwa, umphumela uwonke ungase ubulale.Njengomsebenzisi, kufanele uqaphele ngokwanele.Ibhethri ye-Li-ion ebhoboziwe ingase ibangele izingozi zomlilo ezimbi kakhulu.Njengoba ama-electrolyte anamandla angase avuze kuwo wonke umgodi, ukusabela kwamakhemikhali kwenzeka ngendlela yokushisa.Okokugcina, ukushisa kungase kulimaze amanye amaseli ebhethri, kudale umonakalo omkhulu.
Ibhethri ye-lithium emanzini ingase ibangele ukukhululwa kwe-nail polish njengephunga ngenxa yokwakheka kwe-dimethyl carbonate.Ungase uyinuke kodwa iphunga kangcono imizuzwana embalwa kuphela.Uma ibhethri livutha, khona-ke i-fluoric acid iyakhululwa engase ibangele izinga eliphezulu lezifo zomdlavuza.Kuzophumela ekuncibilikeni kwezicubu zamathambo nezinzwa zakho.
Le nqubo yaziwa ngokuthi i-thermal runaway okuwumjikelezo oziqinisayo.Ingase iholele ekulilweni kwebhethri ebangeni eliphezulu kanye neminye imicimbi ehlobene nokusha.Intuthu eyingozi enye ingozi ehambisana nokuvuza kwebhethri.Ukukhishwa kwe-carbon monoxide ne-hydrofluoric acid kungase kucasule isikhumba ngemva kwamahora amade wokuchayeka.
Ukuhogela intuthu isikhathi eside kungase kubangele izingozi ezisongela ukuphila.Ngakho-ke, kungcono ukungalingi impilo yakho.
Manje, ukucwilisa ibhethri ye-lithium emanzini anosawoti, khona-ke ukusabela kuyoba into ephawulekayo.Usawoti uyancibilika emanzini, ngaleyo ndlela ushiye ama-ion sodium nama-chloride ion ngemuva.I-ion ye-sodium izofuduka iye ngasethangini ene-negative charge, kuyilapho i-ion ye-chloride ithuthela ethangini ibe nokushajwa okuhle.
Ukucwiliswa kwebhethri ye-Li-ion emanzini anosawoti kuzoholela ekukhishweni okuphelele ngaphandle kokuphazamisa izici zebhethri.Ukushajwa ngokugcwele kwebhethri akuthinti umjikelezo wempilo walo lonke uhlelo lwesitoreji.Ngaphezu kwalokho, ibhethri lingahlala amasonto ngaphandle kokushajwa.Ngalesi sizathu, isidingo sesistimu yokugcinwa kwebhethri siyehla.
Inkokhelo ilawulwa ngokuzenzakalela ngezenzo ze-ionic.Ingenye yezindlela eziphephe kakhulu njengoba ingekho ingozi yokubamba umlilo.Ukucwiliswa kwamabhethri e-Li-ion emanzini anosawoti kuzosiza ekwandiseni ubude bempilo yebhethri.Okokugcina kodwa hhayi okuncane;kuyindlela ekhethwa kakhulu ngesikhathi sobungani bemvelo.
Ukucwiliswa kweibhethri ye-lithium-ionemanzini anosawoti aqeda izidingo ezinciphayo zezinxushunxushu zezombangazwe nezomnotho.
Ngokungafani ne-saltwarer, ukucwiliswa kwebhethri ye-Li-ion emanzini kungase kubangele ukuqhuma okuyingozi.Umlilo owenzekayo uyingozi kakhulu kunomlilo ojwayelekile.Ukulimala kukalwa ngakho kokubili ngokoqobo nangokomfanekiso.Umzuzu lapho i-Lithium iqala ukusabela ngamanzi, igesi ye-hydrogen ne-lithium hydroxide iyakhululwa.
Ukuchayeka ngokweqile ku-lithium hydroxide kungase kubangele izinga eliphezulu lokucasuka kwesikhumba kanye nokulimala kweso.Njengoba kukhiqizwa igesi evuthayo, ukuthela amanzi emlilweni we-lithium kungase kube yingozi nakakhulu.Ukukhiqizwa kwe-hydrofluoric acid kungase kubangele isimo esinobuthi kakhulu, ngaleyo ndlela kucasule amaphaphu namehlo.
Ukuntanta kwe-lithium emanzini ngenxa yokuminyana okuphansi ngenxa yokuthi umlilo we-lithium ungase ube nzima kakhulu.Umlilo ovelayo ungase ubonakale unzima mayelana nokucisha.Kungase kuphumele ekuvukeni uma kunesimo esiphuthumayo esikhethekile.Njengoba amabhethri e-lithium kanye nezingxenye kutholakala ngokuhlukahluka nosayizi, kubaluleke kakhulu ukuthi ulungele ukuhlangabezana nanoma yiluphi uhlobo lwesimo esiphuthumayo.
Enye ingozi eyengeziwe ehlobene nokucwiliswa kweamabhethri e-lithium-ionemanzini akukho okunye ngaphandle kwengozi yokuqhuma.Zenzelwe ngokukhethekile ukukhiqizwa kokushaja okuphelele ngesisindo esincane.Idinga ama-casings amancane kakhulu nama-partitions phakathi kwamaseli.
Ngakho-ke, ukuthuthukiswa kuholela ekushiyeni igumbi ngokuya ngokuqina.Lokhu kungase kubangele ukulimala kalula kwezingxenye zangaphakathi nezangaphandle zebhethri.
Ngakho-ke, kulokhu okungenhla kuyacaca ukuthi nakuba amabhethri e-Lithium ewusizo namuhla;noma kunjalo kufanele ziphathwe ngokucophelela ngokwanele.Njengoba kungenzeka ukuthi ziqhume ngemuva kokuthintana namanzi, kuhle ukuthi uqaphe kakhulu.Ukuphatha ngokucophelela kuzoqinisekisa ukuvinjelwa ezingozini ezihlobene nempilo kanye nezingozi ezibulalayo.
