Ubomi bebhetri ye-lithium yemoto yombane kunye nezilumkiso

Umbhali : Iflowpower - UMboneleli weSikhululo saMandla esiphathwayo

Ibhetri ye-lithium yemoto yombane ihlukaniswe ngokukodwa kwiindidi ezintathu ezinkulu. Eyokuqala yi-yuan ye-lithium ezintathu, ekwayeyona isetyenziswa kakhulu ibhetri ye-lithium, ibhetri yesibini ye-phosphate, kunye neyesithathu i-titanate, apho i-lithium titanate iphantsi kakhulu. Abantu abambalwa.

Lide kangakanani inani leebhetri ze-lithium zesithuthi sombane? Ngaba uyayazi indlela yokusebenzisa ibhetri ye-lithium ngokuchanekileyo? Namhlanje, uXiaobian uthetha ngayo. Ubomi bebhetri ye-lithium yemoto yombane yenzelwe ukuba ibe ngamaxesha angama-1000 (ibhetri ye-yuan yesithathu ye-lithium), eyi-3-4 iminyaka. Kodwa oku akuthethi ukuba emva kweminyaka emi-3-4 ubomi bebhetri lithium kupheliswa.

Ibhetri ye-lithium iron phosphate yenye yebhetri ye-lithium ion. Okwangoku, inani lokutshaja kweebhetri ze-lithium phosphate linokufikelela kumaxesha angama-10,000, kwaye ubomi benkonzo ye-cyclic bunokufikelela kwi-7-8 iminyaka. Inokuzaliswa ngaphezu kwemizuzu engama-40 ngexesha.

Ngokuqhelekileyo yibhetri ye-lead-asidi ngokubanzi elingana nebhetri ye-lead-acid 12-15. Ubomi obude bomjikelo webhetri ye-acid bujikeleze amaxesha angama-300, elona liphezulu ngamaxesha angama-500, ngelixa ibhetri ye-lithium phosphate, ubomi bomjikelezo bufikelela kumaxesha angaphezu kwama-2,000, ukutshaja okuqhelekileyo (iiyure ze-5), kunokufikelela kumaxesha angama-2000. Umgangatho ofanayo webhetri ye-lead-acid "yisiqingatha sonyaka omtsha, unyaka wesiqingatha esidala, ukugcinwa kunye nokugcinwa kunye nesiqingatha sonyaka", ukuya kuthi ga kwi-1 ukuya kwi-1.

Iminyaka emi-5, ngelixa iibhetri ze-lithium iron phosphate zisetyenziswa phantsi kweemeko ezifanayo, ubomi bethiyori buya kufikelela kwiminyaka eyi-7-8. Ukuqwalaselwa ngokubanzi, ixabiso lentsebenzo lingaphezulu kwamaxesha e-4 ngaphezulu kwebhetri ye-lead-acid kunethiyori. Ubomi bebhetri ye-lithium yemoto yombane, ingxaki kunye nebhetri ye-lithium kufuneka inikwe ingqwalasela malunga nokutshaja, kwaye okona kuvuyisa ngakumbi kukuba iye yaphuhliswa ukwandisa ubomi bebhetri ye-lithium, kodwa le teknoloji ayiqhelekanga, iindaba Emva kokuqhuma, abathengi abaninzi balindeleke, nangona ubomi beebhetri ze-lithium bunokwandiswa, kodwa wonke umntu kufuneka asebenzise ukusetyenziswa okuchanekileyo ukuqinisekisa ukuba iibhetri ze-lithium aziyi kuqhutyelwa kwangaphambili.

Izinto eziluncedo kwimoto yombane i-lithium ibhetri 1. Ubunzima bebhetri ye-Lithium Umthamo wokukhanya Umthamo omncinci we-lithium ibhetri yombane okwangoku ihlukeneyo, ngokuhambelana nokusebenza okuguquguqukayo, kunye neebhetri ze-lead-acid, ukutshaja i-6 ~ 8 iiyure, zinokuqhuba i-30 ukuya kwiikhilomitha ze-45 ngokuxhomekeke kumthamo webhetri. Ubunzima bumalunga ne-1/5 kuphela yebhetri ye-lead-acid, kwaye ibhetri ye-lithium jikelele okwangoku iqinisekisiwe iminyaka eyi-2, kwaye ibhetri ye-lead-acid iqinisekisa unyaka we-1.

I-2, ibhetri ye-lithium inempawu esebenzayo ye-lithium ibhetri kulula ukuyisebenzisa, nje ngokuba idlula kwi-3-5 intlawulo eqhelekileyo kunye nemijikelezo yokukhupha, ibhetri inokuthi isebenze, kwaye umthamo oqhelekileyo ubuyiselwe. Ngenxa yeempawu zebhetri ye-lithium ngokwayo, inquma ukuba akukho phantse impembelelo yememori. Ngoko ke, ibhetri entsha ye-lithium yomsebenzisi ikwinkqubo yokuvula, ayifuni iindlela ezikhethekileyo kunye nezixhobo.

3. I-4, ibhetri ye-lithium ejikeleza ubomi obude ibhetri ye-lithium ion ibhetri kwi-1C yokukhulisa, ukukhutshwa, ubomi bomjikelezo bukhulu okanye bulingana namaxesha angama-500, ubuninzi be-capacitance bukhulu kunomqadi wobhedu olubizwa ngokuba ngama-70%. Ibhetri ye-lead-asidi ihlawuliswa ngo-0.

I-15c, kwaye ubomi bomjikelezo bungaphantsi okanye bulingana namaxesha angama-350, kwaye i-capacitance ingaphantsi okanye ilingana ne-60%. I-5, iqondo lobushushu elisebenzayo libanzi ibhayisekile yombane ye-lithium-ion ibhetri inokusebenza ngaphakathi -25 degrees ukuya kuma-55 degrees, kunye ne-capacitance ukufikelela kwi-70% yomthamo oqhelekileyo, kunye nebhetri ye-lead-acid inokusebenza kuphela ngaphakathi kwe-10 degrees ukuya kuma-40 degrees. Musa ukusebenza kakuhle xa -25 degrees.

I-6, ixesha lokutshaja ibhetri ye-lithium lifutshane, ukukhuselwa kokusingqongileyo okuluhlaza kubangelwa iimpawu zebhayisiki ye-lithium-ion ibhetri yombane, ngoko ixesha lokutshaja liyi-4-5 iiyure kuphela, ngelixa ibhetri ye-lead-acid ithatha i-8 kwiiyure ze-10. I-Heavy metal lead, iyingozi kwimo engqongileyo, iyeyemveliso ephezulu yokusingqongileyo. ImiGaqo yeBattery yeLithium yeSithuthi soMbane 1.

Ngenxa yokuba ibhetri ye-lithium emva kokusetyenziswa ikwimo yomjikelezo ongekho nzulu, ukutshaja kuya kwandisa ubomi bebhetri yemoto yombane yonke imihla. I-2, ukutshaja ngexesha elifanelekileyo ngenxa yokuba ibhetri ye-lithium yemoto yombane iya kungena kwinkqubo ye-vulcanization emva kokukhutshwa, ukuba ihlawuliswa, inokususa i-vulcanization engekho kakhulu. Ngoko ke, ibhetri ye-lithium iya kuhlawuliswa ngokukhawuleza emva kokuyisebenzisa, ukwenzela ukuba amandla ebhetri agcwele ngokusemandleni.

I-3, iiseli ezikhutshwa rhoqo ezinzulu Ukuqhuba rhoqo ukukhutshwa okunzulu kukwanceda kwibhetri "yokuvula", enokuphucula kancinci amandla ebhetri ye-lithium. Indlela eqhelekileyo kukukhupha ibhetri ngamaxesha athile. Indlela ekhutshwe ngokupheleleyo kukukhwela ukhuseleko lokuqala lwe-undervoltage phantsi komthwalo oqhelekileyo wepavement flat.

Emva kokuba ibhetri ikwindawo yokuqala yokukhusela i-undervoltage, ibhetri ibuyele kwi-non-output ye-non-voltage state emva kwexesha elithile, kwaye umthamo webhetri uya kuphuculwa. Kufuneka kuqatshelwe ukuba xa ibhetri ye-lithium iqala ukukhusela i-undervoltage, ungasebenzisi ibhetri, eli xesha liyingozi kakhulu kwibhetri ye-lithium. 4, zama ukusebenzisa itshaja yokuqala, itshaja yelithium yebhetri yomenzi ngamnye inesidingo somntu, musa indawo yetshaja xa ingenakukwazi.

Ukongeza, musa ukususa umda wesantya somlawuli, susa umda wesantya somlawuli, nangona isantya sezinye iimoto sinokuphuculwa, kodwa siya kunciphisa ubomi bebhetri. Oku ngasentla bubomi besithuthi sombane se-lithium ubomi bebhetri kunye nokusetyenziswa okuchanekileyo. Ithiyori yobomi bebhetri ye-lithium kufuneka ibe yiminyaka eyi-4-6, kwaye itshaja ekhethekileyo kufuneka isetyenziswe ukulimaza ibhetri.

Intlawulo kunye nokukhutshwa kwebhetri ye-lithium iron phosphate ngamaxesha angama-2,000.
