Isingeniso：
Selokhu yangena emakethe,amabhethri e-lithiumasetshenziswe kabanzi ngenxa yezinzuzo zawo ezifana nokuphila isikhathi eside, umthamo omkhulu othize, kanye nokungasebenzi kahle kwenkumbulo. Uma esetshenziswa emazingeni okushisa aphansi, amabhethri e-lithium-ion anezinkinga ezifana nomthamo ophansi, ukuncishiswa okukhulu, ukusebenza kahle kwesilinganiso somjikelezo, imvula ecacile ye-lithium, kanye nokufakwa nokukhishwa kwe-lithium okungalingani. Kodwa-ke, njengoba insimu yokusetshenziswa iqhubeka nokukhula, imingcele ebangelwa ukusebenza kabi kokushisa okuphansi kwamabhethri e-lithium-ion iya ngokuya icaca. Ake sihlole izizathu futhi sichaze ukuthi singawaphatha kanjani amabhethri e-lithium ngendlela efanele ebusika?
Ingxoxo ngezinto ezithinta ukusebenza kwezinga lokushisa eliphansi kwamabhethri e-lithium
1. Ithonya le-Electrolyte
I-electrolyte inomthelela omkhulu ekusebenzeni kwezinga lokushisa eliphansiamabhethri e-lithium. Ukwakheka kanye nezakhiwo ze-physicochemical ze-electrolyte zinomthelela obalulekile ekusebenzeni kwebhethri ekushiseni okuphansi. Inkinga ebhekene nomjikelezo webhethri ekushiseni okuphansi ukuthi i-viscosity ye-electrolyte izokwanda, ijubane lokuqhuba ama-ion lizoncipha, okuholela ekungahambelani kwejubane lokufuduka kwama-electron kwesekethe yangaphandle, ngakho-ke ibhethri lizohlukaniswa kakhulu futhi amandla okushaja nokukhipha azokwehla kakhulu. Ikakhulukazi uma kushajwa ekushiseni okuphansi, ama-ion e-lithium angakha kalula ama-dendrite e-lithium ebusweni be-electrode engemihle, okubangela ukwehluleka kwebhethri.
2. Ithonya lezinto ezingezinhle ze-electrode
- Ukuhlukaniswa kwebhethri kuba kubi kakhulu ngesikhathi sokushaja nokukhipha izinga eliphezulu lokushisa eliphansi, futhi inani elikhulu le-lithium yensimbi lifakwa ebusweni be-electrode engemihle. Umkhiqizo wokusabela we-lithium yensimbi kanye ne-electrolyte ngokuvamile awuhambisani nogesi;
- Ngokombono we-thermodynamic, i-electrolyte iqukethe inani elikhulu lamaqembu e-polar njenge-CO ne-CN, angasabela ngezinto ze-electrode ezingezinhle, futhi ifilimu ye-SEI eyakhiwe isengozini enkulu yokushisa okuphansi;
- Kunzima ngama-electrode angenayo i-carbon ukufaka i-lithium emazingeni okushisa aphansi, futhi kukhona ukungalingani ekushajeni nasekukhipheni i-lithium.
Ungawaphatha kanjani amabhethri e-lithium ngendlela efanele ebusika?
1. Ungasebenzisi amabhethri e-lithium ezindaweni ezishisa kakhulu
Izinga lokushisa linomthelela omkhulu kumabhethri e-lithium. Uma izinga lokushisa liphansi, umsebenzi wamabhethri e-lithium uyancipha, okuholela ngqo ekunciphiseni okukhulu ekusebenzeni kahle kokushaja nokukhipha ishaja. Ngokuvamile, izinga lokushisa lokusebenza le-amabhethri e-lithiumiphakathi kwama-degrees angu-20 nama-degrees angu-60.
Uma izinga lokushisa lingaphansi kuka-0℃, qaphela ukuthi ungashaji ngaphandle. Awukwazi ukushaja noma ngabe uyashaja. Singayisa ibhethri ngaphakathi ukuze lishaje (qaphela, qiniseka ukuthi uhlala kude nezinto ezivuthayo!!!). Uma izinga lokushisa lingaphansi kuka-20℃, ibhethri lizongena ngokuzenzakalelayo esimweni sokungalali futhi alikwazi ukusetshenziswa ngokujwayelekile. Ngakho-ke abasebenzisi enyakatho babanda kakhulu.
Uma kungekho simo sokushaja ngaphakathi, sebenzisa ngokugcwele ukushisa okusele lapho ibhethri likhishwa, bese ulishaja elangeni ngokushesha ngemva kokupaka ukuze wandise inani lokushaja futhi ugweme imvula ye-lithium.
2. Yakha umkhuba wokushaja njengoba uyisebenzisa
Ebusika, lapho amandla ebhethri ephansi kakhulu, kumelwe siwashaje ngesikhathi futhi sithuthukise umkhuba omuhle wokushaja njengoba uwasebenzisa. Khumbula, ungalokothi ulinganise amandla ebhethri ebusika ngokwempilo yebhethri evamile.
Ebusika, umsebenzi weamabhethri e-lithiumukwehla, okungase kubangele kalula ukukhishwa kwebhethri ngokweqile kanye nokushaja ngokweqile, okungase kuthinte impilo yebhethri noma kubangele ngisho nezingozi zokushaja. Ngakho-ke, ebusika, kufanele unake kakhulu ukushaja ngendlela yokushaja engajulile kanye nendlela yokushaja engajulile. Ikakhulukazi, ungayipaki imoto isikhathi eside ngenkathi ushaja ukuze ugweme ukushaja ngokweqile.
3. Ungahlali kude uma ushaja. Khumbula ukungashaji isikhathi eside.
Ungayishaji imoto isikhathi eside ukuze kube lula. Vele uyikhiphe uma isishajiwe ngokugcwele. Indawo yokushaja ebusika akufanele ibe ngaphansi kuka-0℃. Uma ushaja, ungashiyi kude kakhulu ukuze uvimbele izimo eziphuthumayo futhi ubhekane nazo ngesikhathi.
4. Sebenzisa ishaja ekhethekile yamabhethri e-lithium uma ushaja.
Imakethe igcwele amashaja asezingeni eliphansi. Ukusebenzisa amashaja asezingeni eliphansi kuzodala umonakalo ebhethri futhi kubangele ngisho nemililo. Ungathengi imikhiqizo engabizi futhi engavikelekile ngenxa yentengo ephansi, ingasaphathwa eyokusebenzisa amashaja ebhethri le-lead-acid; uma ishaja yakho ingasetshenziswa ngendlela evamile, yeka ukuyisebenzisa ngokushesha, futhi ungalahlekelwa isithombe esikhulu salokho okuncane.
5. Naka impilo yebhethri bese uyishintsha ngesikhathi
Amabhethri e-lithiuminesikhathi sokuphila. Imininingwane ehlukene namamodeli anesikhathi sokuphila esihlukile. Ngaphezu kwalokho, ngenxa yokusetshenziswa okungafanele kwansuku zonke, isikhathi sokuphila kwebhethri sisukela ezinyangeni ezimbalwa kuya eminyakeni emithathu. Uma imoto ilahlekelwa amandla noma isikhathi sokuphila kwebhethri sifushane ngendlela engavamile, sicela uxhumane nabasebenzi bokulungisa ibhethri le-lithium ngesikhathi ukuze bakuphathe.
6. Shiya amandla athile ebusika
Ukuze usebenzise imoto ngokujwayelekile entwasahlobo yonyaka ozayo, uma ibhethri lingasetshenziswa isikhathi eside, khumbula ukulishaja kufike ku-50%-80%, ulikhiphe emotweni ukuze uligcine, bese ulishaja njalo, cishe kanye ngenyanga. Qaphela: Ibhethri kumele ligcinwe endaweni eyomile.
7. Beka ibhethri ngendlela efanele
Ungalicwilisi ibhethri emanzini noma ulimanzise; ungalifaki ibhethri ngaphezu kwezingqimba eziyi-7, noma uguqule indlela ibhethri elibheke ngayo.
Isiphetho
Ku--20℃, amandla okukhipha amabhethri e-lithium-ion angaba ngu-31.5% kuphela walokho ekushiseni kwegumbi. Izinga lokushisa lokusebenza kwamabhethri e-lithium-ion endabuko liphakathi kuka--20 no-+55℃. Kodwa-ke, emikhakheni yezindiza, imboni yezempi, izimoto zikagesi, njll., amabhethri ayadingeka ukuze asebenze ngokujwayelekile ku--40℃. Ngakho-ke, ukuthuthukisa izakhiwo zokushisa eziphansi zamabhethri e-lithium-ion kubaluleke kakhulu. Vele, iibhethri le-lithiumImboni ithuthuka njalo, futhi ososayensi bayaqhubeka nokufunda amabhethri e-lithium angasetshenziswa emazingeni okushisa aphansi ukuxazulula izinkinga zamakhasimende.
