I-Lithium ibalulekile kwizixhobo ezinjenge-smartphones, iilaptops, izithuthi zombane, kunye neenkqubo zamandla ahlaziyiweyo. Abathengi bahlala bebuza ukuba ezibambisi zihlala ixesha elingakanani ngaphambi kokutshintsha. Esi sikhokelo sibonisa izinto ezichaphazela Ibhetri yebhetri yeLithium kwaye ibonelela ngolwazi oluhlala lude. Masingene!
Yintoni i-lithium yebhetri yebhetri?
I Ubomi bomjikelo Ibhetri ye-Lithium ibhekisa kwinani lentlawulo kunye nokugxotha imijikelezo inokugcwalisa ngaphambi kokusebenza kwayo.
Ngexesha lokutshaja, i-lithium i-ions isuka kwi-cathode ukuya kwi i-anode nge i-electrolyte kwaye ubuye ngexesha lokukhupha. Le nkqubo ngokuthe ngcembe ihlazisa izixhobo zebhetri, ezikhokelela ekulahlekelweni kwezakhono ngokuhamba kwexesha.
Ngokwesiqhelo, abavelisi bachaza ubomi bomjikelo njengoko inani lemijikelezo ibhetri inokuhamba ngaphambi kokuba igcinwe malunga ne-80% yomthamo wayo wokuqala. Umzekelo, ibhetri ikalwe imijikelezo engama-500 inokuhlawuliswa kwaye ikhutshwe amaxesha angama-500 ngaphambi kokufikelela emnyango.
Ungabalwa njani umjikelo wobomi beebhetri ze-lithium
Qonda ingcaciso yebhetri
Qokelela ulwazi malunga nebhetri ye-lithium, kubandakanya amandla ayo okuqhelekileyo (I-Amprere-yure.
Chonga ubunzulu bokukhupha (i-DOD)
I-DOD ibonisa umthamo webhetri osetyenzisiweyo kumjikelo ngamnye. Umzekelo, ukuphembelela ibhetri ye-100 ye-100 ukuya kwi-8ah iziphumo kwi-DOD yama-20%. Ezinye iibhetri zinomjikelezo omde ebomini.
Bala umthamo ophumelelayo
Ukufumana isikhundla esisetyenzisiweyo kumjikelo ngamnye, uphinda-phinda ubungakanani bebhetri ngabantu obunzulu. Ibhetri ye-100 ye-AH ekhutshiwe kwi-80%, ubungakanani bomjikelo ngamnye yi-100 Ah × 0.8 = 80 Ah.
Bala i-cycles iyonke
Yahlula-hlula umthamo webhetri ngobunzulu bokukhutshwa komjikelo ngamnye. Umzekelo, ibhetri ye-100 ye-100 ye-20% DOD ivelisa i-500 yemijikelezo (i-100ah / 20/100) = 500 imijikelezo).
Cinga ukwaluphala kwebhetri kunye nezinto zokusingqongileyo
Ubomi bebhetri bunokuphenjelelwa ngamaqondo obushushu, ukubiza / iirhafu zokulawula, kunye neendlela zolawulo; Amaqondo obushushu aphezulu okanye ukutshata ngokukhawuleza kunokukhawulezisa ukonakaliswa kwaye kuncitshiswe i-liespan.
Ngaba iibhetri zeLithium zihlala ixesha elide kunezinye iibhetri?
I-Lithium Bhateries iphuhlise ezinye iintlobo zeebhetri, zihambisa ixesha elide lobomi bexesha lokukhetha okunzulu.
Nalu uqhetseba iintlobo zebhetri ye-lithium kunye neepani zobomi babo:
- I-Lithium-ion (i-li-ion): isetyenziswe ngokubanzi kwi-elektroniki kunye nezithuthi zombane, i-li-ion ibhetri ihlala iminyaka emi-2 ukuya kweli-10.
- I-Lithium i-phosphate (i-worpo4): Iyaziwa ngokhuseleko kunye nobomi obude, iibhetri zeLiFePO4 Ingahlala iminyaka emi-5 ukuya kweli-15.
- I-Lithium Polymer (I-IPO): isetyenziswa ngokuqhelekileyo kwi-drones kunye nezixhobo ze-RC, iibhetri ze-lipo zinexesha eliphantsi kweminyaka emi-2 ukuya kweli-5.
- I-Lithium Manganese Oxide (Limn24): Ihlala isetyenziswa kwizixhobo zamandla kunye nezixhobo zonyango, iibhetri ze-Limn22 zineminyaka yobomi beminyaka emi-3 ukuya kweli-7.
Ungalufumana njani ixesha elide lobomi
Ukuphelisa i-Lithium Lifestan, cinga ngezi zinto:
Ubushushu
Amaqondo obushushu aphezulu anokuthi anqumle iibhetri ze-lithium’ Ubomi bexesha, ngelixa amaqondo obushushu asezantsi anokunciphisa ukusebenza. Umzekelo, iibhetri ze-Wicpo4 zinokusebenza phakathi kwe--20 ℃ ukuya kwi-60 ℃ (-4 ℉ ukuya kwi-140 ℉).
Ukuhlawula ngaphezulu
Iibhetri ezigqithisileyo ze-Lithium ze-Lithium ezinokubangela ukuba zonakalise kwaye zinciphise ubomi babo. A BMS (Inkqubo yolawulo lwebhetri) ibalulekile, njengoko ikhusela ngokuchasene nokumalunga nokusasaza nokusasaza, iiseli ezinokuqiqa, zilawula ubushushu, nangaphezulu.
Inqanaba lokubiza
Sebenzisa itshaja edibana ngqo nenkcazo yomenzi; Ukutshaja ngokukhawuleza kunokulimaza iibhetri.
Iimeko zokugcina
Gcina iibhetrium kwindawo epholileyo, eyomileyo yokuthintela ukonakaliswa kwamachiza.
Kulumkele ukonakala komzimba
Thwala iibhetri ze-lithium ngononophelo ukuthintela amathontsi, ukuxhuzula, okanye ukuvezwa komswakama okunokubangela ukuba kubetha kwaye kudale iingozi zokhuseleko.
Ngaba iibhetri zeLithium kufuneka zigcinwe ngokupheleleyo?
Kwiibhetri zeLithium, zihlise kuzo nawuphi na umthombo wamandla, kubandakanya nerediyo kunye neewotshi, ukuba azisebenzi. Gcina iibhetri ubuncinci ubuncinci kwi-50% yentlawulo; Igcinwe ngokufanelekileyo, ibhetri ehlawulwayo ngokupheleleyo ingahlala unyaka.
Ngaba iibhetri ze-lithium ziphelelwe lixesha ukuba azisetyenziswanga?
I-Lithium Bitries ayiphelelwa lixesha kodwa ilahlekelwe ngama-2-3% yamandla abo ngenyanga xa ishiywe ingenamda phantsi kweemeko ezifanelekileyo. Ukuba igcinwe ixesha elide ngaphandle kokubiza, zinokufa ngokupheleleyo. Nangona kunjalo, le nkqubo ithatha ixesha.
Ngaba iibhetri ze-lithium-ion ifanele?
Iibhetri ze-lithium-ion I-Superst i-Coude-Acid Butteres Ngandlela zonke. Zikhaphuka, zinamandla amakhulu, kwaye zibe nenqanaba lokuziqaqambisa eliphantsi. Ukongeza, bafuna ulondolozo oluncinci kwaye luhlale ixesha elide. Nangona iindleko eziphezulu ziphezulu, imali epheleleyo ibalulekile.
