Gcina indlela entsha yokutshaja ibhetri

Izithuthi zombane ziya zisiba nobuchule ngakumbi kwaye zikrelekrele. Uphando kunye nophuhliso kunye neteknoloji yokuvelisa izithuthi zombane ziyaqhubeka ziqhubela phambili, kwaye iteknoloji yokuvelisa izithuthi zombane zikhula ngakumbi. Xa iibhetri ze-lithium zeebhayisikili zombane zithandwa kwimarike, abantu abaninzi abacaci kakuhle malunga nendlela yokutshaja iibhetri ze-lithium kwizithuthi zombane. Andazi ukuba ndingayigcina njani. Namhlanje, ndiya kwazisa ukugcinwa kwezithuthi zombane ze-lithium kunye neendlela ezintsha zokutshaja ibhetri.

1. Indlela entsha yokutshaja ibhetri

Ukusebenza kwebhetri yeLithium sisihloko esidala. Inxalenye enkulu yabathengi bakholelwa ukuba imfuno yokusebenzisa ibhetri inkulu. Phantse bonke abathengisi bathi amaxesha amathathu okuqala azele iiyure ze-12, ngokucacileyo ukusuka kwicala elithe nkqo leebhetri ze-nickel (njenge-nickel-cadmium kunye ne-nickel-metal hydride). Phantsi. Kunokuthiwa le mbono yagqwethwa kwasekuqaleni. Iimpawu zokutshaja kunye nokukhupha iibhetri ze-lithium zihluke kakhulu kwiibhetri ze-nickel. Ngokucacileyo, zonke iincwadi ezinzulu kunye nezisesikweni zobuchwephesha endizifundileyo zigxininise ukuba i-overcharge kunye ne-overdischarge inokubangela umonakalo omkhulu kwiibhetri ze-lithium, ngakumbi iibhetri zamanzi.

Ngaba uyafuna ukwenza ibhetri isebenze? Ndiphendule, ewe, kuyimfuneko ukuyivula! Nangona kunjalo, inkqubo iyapheliswa ngumenzi, kungekhona ngumsebenzisi, kwaye umsebenzisi akanakho ukukwazi ukuphelisa. Eyona nkqubo yokuvula imi ngolu hlobo lulandelayo: Ibhetri ye-lithium, iqokobhe le-lithium yebhetri itywiniwe nge-electrolyte yolwelo olufakwayo, ehlawuliswa ngamandla ombane rhoqo emva koko ikhutshwe. Kwimijikelo embalwa enjalo, i-electrode ingena kumandla okusebenza atyebileyo e-electrolyte ide ihlangabezane nemfuneko yokuxhoma amandla. Ingumxholo wenkqubo yokuvula. Kwakhona kuthiwa emva kokuba bemkile, ibhetri ye-lithium yenziwe ngumsebenzisi. Ukongeza, kwangaxeshanye, inkqubo yokuqalisa ukusebenza kwezinye iibhetri ifuna ukuba ibhetri ivulwe kwaye itywinwe. Ngaphandle kokuba unezixhobo zokuvelisa ibhetri, ungayiphelisa njani? Ibhetri iya kuphuma kumzi-mveliso ize ithengiselwe umsebenzisi. Kuya kuthatha ixesha, inyanga okanye ezimbalwa. Iinyanga, ke, izinto ze-electrode zebhetri ziya kudlula, kucetyiswa ukuba kusetyenziswe ibhukwana lebhetri okokuqala ngqa ndinenkqubo yokuzalisa ngokucokisekileyo kathathu, ukuze kukhawuleziswe ukupheliswa kwe-passivation, i-electrode material ingaba yaziwa ngempumelelo. Kodwa oku akuthathi iiyure ezili-12. Kufuneka iyeke amaxesha amaninzi. Ukugqithiswa kunokupheliswa emva kokusetyenziswa okuqhelekileyo ixesha elithile. Ngoko ke, umsebenzisi akayona indlela ekhethekileyo kunye nesixhobo kwinkqubo yokuqalisa ibhetri entsha ye-lithium.

Ukongeza, xa ibhetri ihlawuliswe ngokupheleleyo, ibhetri ye-lithium okanye ishaja iya kuyeka ngokuzenzekelayo ukutshaja. Akukho tshaja yenickel enokuhlala ngaphezulu kweeyure ezili-10. Ngamanye amazwi, ukuba ibhetri yakho ye-lithium ihlawuliswe ngokupheleleyo, ayiyi kuhlawuliswa kwitshaja. Asinakuqinisekisa ukuba iimpawu zomrhumo kunye nokukhuselwa kwesekethe aziyi kutshintsha, ngoko ke ibhetri yakho iya kuba semngciphekweni wengozi ixesha elide. Esi sesinye isizathu sokuchasa imirhumo yexesha elide. Kwabanye oomatshini, kucingelwa ukuba itshaja ayiyi kususwa emva kokutshaja ixesha elithile. Ngeli xesha, inkqubo ayiyi kuyeka kuphela ukutshaja, kodwa iphinde iqalise umjikelo wokukhupha intlawulo. Abavelisi banokuba nezicwangciso zabo, kodwa ngokucacileyo ezi ziindaba ezimbi kubomi bebhetri. Ngelo xesha, imfuno yokutshaja kwexesha elide ithatha ixesha elide, kwaye imfuno idla ngokuqhutyelwa ebusuku. Nangona kunjalo, ngokujonga imeko yegridi yelizwe lam, amandla ombane ebusuku kwiindawo ezininzi aphakamileyo kwaye aguquguquka kakhulu. Nangona kunjalo, iibhetri ze-lithium zibuthathaka kakhulu, kwaye amandla abo okumelana nokuguquguquka kwentlawulo kunye nokukhutshwa kungaphantsi kakhulu kwiibhetri ze-nickel, ngoko kukho imingcipheko eyongezelelweyo.

2, intlawulo kufuneka iqalwe ngexesha lokusetyenziswa okuqhelekileyo

Ekubeni inani lentlawulo kunye nokukhutshwa lilinganiselwe, iibhetri ze-lithium kufuneka zisebenzise amandla amancinci njengoko kunokwenzeka xa utshaja. Kodwa ndafumana intlawulo yebhetri ye-lithium kunye netafile yokuvavanya umjikelo wokukhupha, idatha yobomi bomjikelo ngolu hlobo lulandelayo: ubomi bomjikelezo (10% DOD):> 1000 ubomi bomjikelezo (100% DOD):> imijikelo engama-200, apho iDOD sisifinyezo sobunzulu yokukhupha. Ingabonwa kwitheyibhile ukuba ixesha lokutshaja lihambelana nobunzulu bokukhutshwa, kwaye ubomi bomjikelezo we-DOD ye-10% bude kakhulu kune-DOD ye-100%. Ngokuqinisekileyo, kucingelwa ukuba ukucuthwa kwangempela kwentlawulo kuhambelana nomthamo opheleleyo: * 1000 * 200 = 200 = 100100%, 10% emva kokuba intlawulo igqityiwe.
