Isingeniso:
Kusukela ukungena emakethe,amabhethri e-lithiumbasetshenziswe kabanzi ngezinzuzo zabo njengempilo ende, umthamo omkhulu, futhi akukho mphumela wokukhumbula. Lapho isetshenziswa emazingeni okushisa aphansi, amabhethri e-lithium-ion anezinkinga ezinjengamandla aphansi, i-attiation enzima, ukusebenza kwe-lithium okusobala, ukufakwa kwe-lithium okusobala, nokufakwa kwe-lithium engalingani. Kodwa-ke, njengoba insimu yesicelo iyaqhubeka ukwandisa, izingqinamba ezilethwe ukusebenza kwezinga lokushisa eliphansi lamabhethri e-lithium-ion aqala ngokwengeziwe. Ake sihlole izizathu futhi sichaze ukuthi ungawaphatha kanjani amabhethri e-lithium kahle ebusika?
Ingxoxo ngezinto ezithinta ukusebenza okuphansi kokushisa kwamabhethri we-lithium
1. Ithonya le-electrolyte
I-electrolyte inomthelela omkhulu ekusebenzeni okuphansi kokushisa kweamabhethri e-lithium. Ukwakheka kanye nezakhiwo ze-physicochemical ze-electrolyte zinomthelela obalulekile ekusebenzeni okuphansi kwebhethri. Inkinga ebhekene nomjikelezo webhethri emazingeni okushisa aphansi ukuthi i-viscosity ye-electrolyte izokwanda, i-ion conduction isivinini izokwehlisa amandla, ibhethri lizolahla kanzima kanye necala lokukhipha kanye nelokukhishwa kuzokwehla kakhulu. Ikakhulu uma ishaja ngokushisa okuphansi, ama-lithium ion angakha kalula ama-lithium dendrites ebusweni be-electrode engemihle, ebangela ukwehluleka kwebhethri.
2. Ithonya lezinto ezingezinhle ze-elektrode
- I-petrolanization yebhethri ibaluleke kakhulu ngesikhathi sokushaja okushisa okuphansi okuphezulu nokukhipha, kanti inani elikhulu le-lithium lensimbi lifakwa ebusweni be-electrode engemihle. Umkhiqizo wokuphendula we-lithium wensimbi kanye ne-electrolyte ngokuvamile akusona ngokusebenza;
- Ukusuka ekubukweni kwe-thermodynamic, i-electrodyte iqukethe inani elikhulu lamaqembu ama-polar afana ne-CO ne-CN, engasabela ngezinto ezingezinhle ze-elektrodi, futhi ifilimu le-SEIDLALUNGILE lakhiwa litholakala kakhulu ekushiseni okuphansi;
- Kunzima nge-electrodes emibi ye-carbon ukushumeka i-lithium emazingeni okushisa aphansi, futhi kukhona i-asymmetry ekushaja nasekulahlekeni.
Ungawaphatha kanjani amabhethri e-lithium kahle ebusika?
1. Ungasebenzisi amabhethri e-lithium ezindaweni eziphansi zokushisa
Ukushisa kunomthelela omkhulu kumabhethri e-lithium. I-Yehlisa izinga lokushisa, okwehlile komsebenzi wamabhethri e-lithium, okuholela ngqo ekunciphiseni okukhulu ekushaja nasekusebenzeni kahle. Ngokuvamile ekhuluma, izinga lokushisa elisebenzayo leamabhethri e-lithiumiphakathi kwama-degrees nama-60 degrees.
Lapho amazinga okushisa engaphansi kuka-0 ℃, qaphela ukuthi ungakhokhisi ngaphandle. Singathatha ibhethri ngaphakathi kokushaja (inothi, qiniseka ukuthi ungahlali kude nezinto ezivuthayo !!!). Lapho amazinga okushisa engaphansi -20 ℃, ibhethri lizongena ngokuzenzakalelayo isimo esishisayo futhi alikwazi ukusetshenziswa ngokujwayelekile.
Ngakho-ke, kungenxa yabasebenzisi ezindaweni ezibandayo enyakatho, uma kungekho esimweni sokushaja esingaphakathi, sisebenzisa ngokugcwele ukushisa okusele lapho ibhethri selikhishwe, futhi likukhokhise elangeni ngokushesha ngemuva kokukhulisa inani lokushaja futhi ligweme ukufudumala kwe-lithium.
2. Thuthukisa umkhuba wokushaja njengoba usebenzisa yona
Ebusika, lapho amandla ebhethri aphansi kakhulu, kufanele sikhokhise ngesikhathi futhi sithuthukise umkhuba omuhle wokushaja njengoba uwusebenzisa. Khumbula, ungalokothi ulinganise amandla ebhethri ebusika ngokuya ngempilo yebhethri ejwayelekile.
Ebusika, umsebenzi weamabhethri e-lithiumKwehla, okungadala kalula ukuphuma ngokweqile kanye nokushaja ngokweqile, okungathinta impilo yebhethri noma kubangele izingozi zokuhlanza. Ngakho-ke, ebusika, kufanele unake kakhulu ukushaja kokukhipha okuncane kanye nendlela encane yokukhokhisa. Ikakhulu, ungayipaki imoto isikhathi eside ngenkathi ishaja ukuze ugweme ukwedlula ngokweqile.
3. Ungahlali kude lapho ushaja. Khumbula ukungakhokhisi isikhathi eside.
Ungakhokhisi imoto isikhathi eside ukuze kube lula. Vele ukhiphe uma usukhokhiswa ngokuphelele. Imvelo yokushaja ebusika akufanele ibe ngaphansi kuka-0 ℃. Lapho ishaja, ungashiyi kude kakhulu ukuvikela izimo eziphuthumayo futhi ubhekane nazo ngesikhathi.
4. Sebenzisa ishaja enikezelwe amabhethri e-lithium lapho ishaja.
Imakethe igcwele amashaja asezingeni eliphansi. Ukusebenzisa amashaja asezingeni eliphansi kuzodala ukulimala kwebhethri futhi kubangele ngisho nemililo. Musa ukuthenga imikhiqizo etholwe ngamanani aphansi futhi engavikelekile ngokushibhile, ukuyeke usebenzise amashaja webhethri le-lead-acid; Uma ishaja yakho ingenakusetshenziswa ngokujwayelekile, yeka ukuyisebenzisa ngokushesha, futhi ungalahlekelwa isithombe esikhulu kwabancane.
5. Naka impilo yebhethri bese uyifaka esikhundleni ngesikhathi
Amabhethri e-lithiumube nesikhathi sokuphila. Ukucaciswa okuhlukile namamodeli anama-Lifespan ahlukile. Ngaphezu kwalokho, ngenxa yokusetshenziswa okungafanele kwansuku zonke, impilo yebhethri isukela ezinyangeni ezimbalwa kuya eminyakeni emithathu. Uma imoto ilahlekelwa amandla noma impilo yebhethri ifushane ngokungafanele, sicela uthinte abasebenzi be-Lithium Lattery Moest Moderal ngesikhathi ukuze basingathe.
6. Shiya amandla ebusika
Ukuze usebenzise imoto ejwayelekile entwasahlobo yonyaka olandelayo, uma ibhethri lingasetshenziswanga isikhathi eside, khumbula ukukhokhisa ku-50% -80%, ususe kusuka emotweni. Qaphela: Ibhethri kufanele ligcinwe endaweni eyomile.
7. Beka ibhethri kahle
Ungagcizeleli ibhethri emanzini noma ukwenze kube manzi; Musa ukubeka ibhethri ngaphezulu kwezendlalelo eziyi-7, noma ungenisa ukuqondiswa kwebhethri.
Ukugcina
Ku-AT -20 ℃, umthamo wokukhipha amabhethri e-lithium-ion acishe abe ngu-31.5% walokho emazingeni okushisa asekamelweni. Ukushisa okusebenzayo kwamabhethri we-lithium-ion aphakathi - 20 no-55 ℃. Kodwa-ke, emasimini ase-Aerospace, Imboni yezempi, izimoto zikagesi, njll., Amabhethri adingekayo ukuze asebenze ngokujwayelekile ku -40 ℃. Ngakho-ke, ukuthuthukisa izindawo zokushisa eziphansi zamabhethri e-lithium-ion abaluleke kakhulu. Vele, theibhethri le-lithiumImboni ihlala ikhula, futhi ososayensi bayaqhubeka nokufunda amabhethri e-lithium angasetshenziswa emazingeni okushisa aphansi ukuxazulula izinkinga kumakhasimende.
IHeltec Energy ngumlingani wakho othembekile ekukhiqizweni kwebhethri yebhethri. Ngokugxila kwethu ngokungapheli kokucwaninga nasekuthuthukisweni, okuhambisana nobubanzi bethu obubanzi bezesekeli zebhethri, Sinikeza izixazululo zokumisa eyodwa ukuze uhlangabezane nezidingo zalo mbombo. Singakwazi ukwenza ngokwezifiso amabhethri e-lithium ngezimo ezahlukahlukene zamakhasimende. Uma udinga ukuthuthukisa ibhethri lakho le-lithium noma ulungiselele ibhodi lokuvikela, sicela uxhumane nathi.
Uma unemibuzo noma ungathanda ukufunda okuningi, sicela ungangabazifinyelela kithi.
