Nhanganyaya：
Kubva zvapinda mumusika,mabhatiri e lithiamudzave dzichishandiswa zvakanyanya nekuda kwezvakanakira zvadzo zvakaita sekugara kwenguva refu, kugona kukuru, uye kusava nemhedzisiro yekurangarira. Kana dzichishandiswa patembiricha yakaderera, mabhatiri e-lithium-ion ane matambudziko akadai sekushanda kwakaderera, kudzikira kwakanyanya, kushanda kwakashata kwe cycle rate, kuyerera kwe lithium pachena, uye kuiswa uye kubviswa kwe lithium zvisina kuenzana. Zvisinei, sezvo nzvimbo yekushandisa iri kuramba ichikura, zvipingamupinyi zvinounzwa nekushanda kwakashata kwemabhatiri e-lithium-ion patembiricha yakaderera zviri kuramba zvichionekwa. Ngationgororei zvikonzero uye titsanangure maitiro ekubata mabhatiri e-lithium nemazvo munguva yechando?
Kukurukurirana pamusoro pezvinhu zvinokanganisa mashandiro emabhatiri e lithium pakupisa kwakaderera
1. Simba reElectrolyte
Iyo electrolyte ine simba guru pakushanda kwekupisa kwakaderera kwemabhatiri e lithiamu. Maumbirwo uye hunhu hwefizikisi ye electrolyte zvine chekuita nekushanda kwebhatiri patembiricha yakaderera. Dambudziko rinotarisana nebhatiri patembiricha yakaderera nderekuti viscosity ye electrolyte ichawedzera, kumhanya kwe conduction ye ion kuchaderera, zvichikonzera kusawirirana mukumhanya kwe electron ye external circuit, saka bhatiri richave rakapatsanurwa zvakanyanya uye simba rekuchaja nekuburitsa richadzikira zvakanyanya. Kunyanya kana richichaja patembiricha yakaderera, lithium ions dzinogona kuumba lithium dendrites nyore nyore pamusoro pe negative electrode, zvichikonzera kutadza kushanda kwebhatiri.
2. Kupesvedzera kwezvinhu zvisina kunaka zve electrode
- Kupatsanurana kwemabhatiri kunonyanya kuipa kana paine kuchaja nekuburitsa simba patembiricha yakaderera, uye huwandu hwakawanda hwesimbi inonzi lithium hunoiswa pamusoro peelectrode isina kunaka. Zvinoitwa nesimbi inonzi lithium ne electrolyte hazviwanzoiti kuti zvinhu zvifambe zvakanaka;
- Kubva pamaonero ethermodynamic, electrolyte ine nhamba yakakura yemapoka epolar akadai seCO neCN, ayo anogona kuita nechinhu cheelectrode chisina kunaka, uye firimu reSEI rakaumbwa rinonyanya kukanganiswa nekupisa kwakaderera;
- Zvakaoma kuti maelectrode asina carbon aise lithium patembiricha yakaderera, uye hapana kuenzana pakuchaja nekuburitsa simba.
Nzira yekurapa mabhatiri e lithium nemazvo munguva yechando?
1. Usashandise mabhatiri e lithium munzvimbo dzine tembiricha yakaderera
Kupisa kunokanganisa zvikuru mabhatiri e lithium. Kana tembiricha yakaderera, basa remabhatiri e lithium rinoderera, izvo zvinotungamira zvakananga kudzikira kukuru mukuchaja nekuburitsa simba. Kazhinji, tembiricha yekushanda yemabhatiri e lithiamutembiricha iri pakati pe -20 degrees ne60 degrees.
Kana tembiricha iri pasi pe0℃, chenjera kuti usachaja panze. Haugone kuichaja kunyangwe ukaichaja. Tinogona kutora bhatiri mumba kuti richajirwe (cherechedza, iva nechokwadi chekuti wagara kure nezvinhu zvinobvira moto!!!). Kana tembiricha iri pasi pe -20℃, bhatiri rinozongoerekana rava muchimiro chekusashanda zvakanaka uye harigone kushandiswa zvakajairika. Saka vashandisi vari kuchamhembe vanotonhora zvakanyanya.
Kana pasina mamiriro ekuchaja mumba, shandisa zvizere kupisa kwasara kana bhatiri rabuda, uye richaje muzuva mushure mekupaka kuti uwedzere huwandu hwekuchaja uye kudzivirira mvura ye lithium.
2. Iva netsika yekuchaja paunenge uchishandisa
Munguva yechando, kana simba rebhatiri rakaderera zvakanyanya, tinofanira kurichaja nenguva uye kuva netsika yakanaka yekuchaja paunenge uchirishandisa. Yeuka, usambofa wafungidzira simba rebhatiri munguva yechando zvichienderana nehupenyu hwebhatiri hwakajairika.
Munguva yechando, basa remabhatiri e lithiamukuderera, izvo zvinogona kukonzera kuburitsa simba rakawandisa uye kuchaja zvakanyanya, izvo zvinogona kukanganisa hupenyu hwebhatiri kana kutokonzera tsaona dzemoto. Saka, munguva yechando, unofanira kutarisisa zvakanyanya pakuchaja pasina kudzika uye pakuchaja zvishoma. Kunyanya, usamisa mota kwenguva yakareba uchichaja kuti usachaja zvakanyanya.
3. Usagara kure paunenge uchichaja. Yeuka kusachaja kwenguva yakareba.
Usachaja mota kwenguva yakareba kuti zvive nyore. Ingoibvisa kana yachaja zvizere. Nzvimbo yekuchaja munguva yechando haifanirwe kunge yakaderera kupfuura 0℃. Paunenge uchichaja, usasiye mota kure zvakanyanya kudzivirira njodzi uye gadzirisa dambudziko racho nenguva.
4. Shandisa charger chaiyo yemabhatiri e lithium paunenge uchichaja.
Musika uzere nemachaja emhando yepasi. Kushandisa machaja emhando yepasi pasi kunokonzera kukuvara kwemabhatiri uye kutokonzera moto. Usatenge zvigadzirwa zvemutengo wakaderera uye zvisina kuchengetedzeka nekuda kwemutengo wakaderera, tisingatauri nezvekushandisa machaja emabhatiri ane lead-acid; kana chaja yako isingakwanise kushandiswa zvakajairika, rega kuishandisa ipapo ipapo, uye usarasikirwa nepfungwa huru pamusoro pezvinhu zvidiki.
5. Teerera nguva yekushanda kwebhatiri woritsiva nenguva
Mabhatiri eLithiumine hupenyu hwenguva refu. Mhando dzakasiyana dzemagadzirirwo uye mamodheru ane hupenyu hwakasiyana. Pamusoro pezvo, nekuda kwekushandiswa zvisina kunaka kwezuva nezuva, hupenyu hwebhatiri hunotangira pamwedzi mishoma kusvika kumakore matatu. Kana mota ikarasikirwa nemagetsi kana hupenyu hwebhatiri hupfupi zvisingawanzoitiki, ndapota taura nevashandi vekugadzirisa bhatiri re lithium nenguva kuti vagadzirise.
6. Siya simba rechando
Kuti mota ishandise zvakanaka muchirimo chegore rinouya, kana bhatiri risingashandiswe kwenguva yakareba, yeuka kurichaja kusvika 50%-80%, kuribvisa mumota kuti richengeterwe, uye kurichaja nguva dzose, kanenge kamwe chete pamwedzi. Cherechedza: Bhatiri rinofanira kuchengetwa munzvimbo yakaoma.
7. Isa bhatiri nemazvo
Usanyike bhatiri mumvura kana kurinyorovesa; usaisa bhatiri munzvimbo dzinopfuura 7, kana kutenderedza bhatiri.
Mhedziso
Pa -20℃, simba rekuburitsa mabhatiri e-lithium-ion rinongosvika 31.5% chete patembiricha yemumba. Tembiricha yekushanda kwemabhatiri echinyakare e-lithium-ion iri pakati pe -20 ne +55℃. Zvisinei, muminda yendege, maindasitiri emauto, mota dzemagetsi, nezvimwewo, mabhatiri anofanirwa kushanda zvakajairika pa -40℃. Saka, kuvandudza hunhu hwematembiricha akaderera emabhatiri e-lithium-ion kwakakosha zvikuru. Ehe,bhatiri re lithiamuIndasitiri iri kuramba ichikura, uye masayendisiti ari kuramba achidzidza mabhatiri e lithium anogona kushandiswa patembiricha yakaderera kugadzirisa matambudziko evatengi.
Heltec Energy ndiyo shamwari yako yaunovimba nayo mukugadzira mabheteri. Nekutarisa kwedu kutsvagurudzo nekuvandudza, pamwe chete nemidziyo yedu yakawanda yemabhatiri, tinopa mhinduro dzese kuti tisangane nezvinodiwa zviri kuchinja muindasitiri. Kuzvipira kwedu kune kugona, mhinduro dzakagadzirirwa vatengi, uye hukama hwakasimba nevatengi zvinoita kuti tive sarudzo yakanaka kune vagadziri vemabheteri nevatengesi pasi rese.
Kana muine mibvunzo kana kuti muchida kuziva zvakawanda, musazeza kupindurataura nesu.
