Intshayelelo:
Ukususela oko ndangena kwimarike,iibhetri ze-lithiumzisetyenziswe kakhulu ngenxa yeengenelo zazo ezifana nokuphila ixesha elide, umthamo omkhulu, kunye nokungabikho kwempembelelo yememori. Xa zisetyenziswa kumaqondo obushushu aphantsi, iibhetri ze-lithium-ion zineengxaki ezifana nomthamo ophantsi, ukuncitshiswa okukhulu, ukusebenza kakubi kwesantya somjikelo, ukuhla kwe-lithium okucacileyo, kunye nokufakwa kunye nokukhupha i-lithium okungalinganiyo. Nangona kunjalo, njengoko intsimi yesicelo iqhubeka nokwanda, imida ebangelwa kukusebenza kakubi kwamaqondo obushushu aphantsi kweebhetri ze-lithium-ion iya icaca ngakumbi nangakumbi. Makhe sihlolisise izizathu kwaye sichaze indlela yokuphatha iibhetri ze-lithium ngokuchanekileyo ebusika?
Ingxoxo ngezinto ezichaphazela ukusebenza kakuhle kwamabhetri e-lithium kubushushu obuphantsi
1. Impembelelo ye-electrolyte
I-electrolyte inefuthe elikhulu ekusebenzeni kobushushu obuphantsiiibhetri ze-lithium. Ulwakhiwo kunye neempawu ze-physicochemical ze-electrolyte zinempembelelo ebalulekileyo ekusebenzeni kwebhetri kubushushu obuphantsi. Ingxaki ejongene nomjikelo webhetri kubushushu obuphantsi kukuba i-viscosity ye-electrolyte iya kwanda, isantya sokuqhuba ii-ion siya kuncipha, nto leyo ebangela ukungalingani kwisantya sokufuduka kwee-electron kwisekethe yangaphandle, ngoko ke ibhetri iya kuba ne-polarized kakhulu kwaye amandla okutshaja kunye nokukhupha aya kwehla kakhulu. Ingakumbi xa itshaja kubushushu obuphantsi, ii-ion ze-lithium zinokwenza ngokulula ii-lithium dendrites kumphezulu we-electrode engalunganga, nto leyo ebangela ukungaphumeleli kwebhetri.
2. Impembelelo yezinto ezingalunganga ze-electrode
- Ukuqhekeka kwebhetri kuba nzima kakhulu xa kutshajwa kwaye kukhutshelwa ngaphandle kwebhetri ngobushushu obuphantsi, kwaye inani elikhulu le-lithium yentsimbi lifakwa kumphezulu we-electrode engalunganga. Imveliso yokusabela ye-lithium yentsimbi kunye ne-electrolyte ngokubanzi ayisebenzi;
- Ngokwembono ye-thermodynamic, i-electrolyte iqulethe inani elikhulu lamaqela e-polar afana ne-CO kunye ne-CN, anokusabela ngezinto ze-electrode ezingalunganga, kwaye ifilimu ye-SEI eyenziweyo isengozini enkulu yobushushu obuphantsi;
- Kunzima kwii-electrode ze-carbon negative ukufaka i-lithium kumaqondo obushushu aphantsi, kwaye akukho ulungelelwaniso ekutshajeni nasekukhupheni i-lithium.
Indlela yokuphatha iibhetri ze-lithium ngokuchanekileyo ebusika?
1. Musa ukusebenzisa iibhetri ze-lithium kwiindawo ezinobushushu obuphantsi
Ubushushu bunempembelelo enkulu kwiibhetri ze-lithium. Okukhona ubushushu buphantsi, kokukhona umsebenzi weebhetri ze-lithium uphantsi, nto leyo ekhokelela ngokuthe ngqo ekunciphiseni okukhulu ekusebenzeni kokutshaja nokukhupha itshaja. Ngokubanzi, ubushushu bokusebenza beiibhetri ze-lithiumiphakathi kwama-degrees angama-20 kunye nama-degrees angama-60.
Xa ubushushu bungaphantsi kwe-0℃, lumka ungatshaji ngaphandle. Awunakutshajisa nokuba uyatshajisa. Singayisa ibhetri ngaphakathi ukuze itshajiswe (qaphela, qiniseka ukuba uhlala kude nezinto ezinokutsha!!!). Xa ubushushu bungaphantsi kwe-20℃, ibhetri iya kungena ngokuzenzekelayo kwimeko yokungalali kwaye ayinakusetyenziswa ngokuqhelekileyo. Ngoko ke abasebenzisi abasemantla babanda kakhulu.
Ukuba akukho meko yokutshaja ngaphakathi, sebenzisa ngokupheleleyo ubushushu obuseleyo xa ibhetri ikhutshiwe, kwaye uyitshaje elangeni emva nje kokupaka ukuze wonyuse ubungakanani bokutshaja kwaye uphephe ukuna kwe-lithium.
2. Yakha umkhwa wokutshaja njengoko uyisebenzisa
Ebusika, xa amandla ebhetri ephantsi kakhulu, kufuneka siwatshaje ngexesha elifanelekileyo size siphuhlise umkhwa wokutshaja njengoko uyisebenzisa. Khumbula, ungaze uqikelele amandla ebhetri ebusika ngokwexesha eliqhelekileyo lobomi bebhetri.
Ebusika, umsebenzi weiibhetri ze-lithiumukuncipha, okunokubangela ukukhupha ibhetri kakhulu kunye nokutshaja kakhulu, okunokuchaphazela ubomi bebhetri okanye kubangele neengozi zokutsha. Ke ngoko, ebusika, kufuneka unikele ingqalelo engakumbi ekutshajeni ngendlela engaphantsi kobushushu kunye nendlela yokutshaja encinci. Ngokukodwa, musa ukupaka imoto ixesha elide ngelixa utshaja ukuze uphephe ukutshaja kakhulu.
3. Musa ukuhlala ecaleni xa utshaja. Khumbula ukungatshaji ixesha elide.
Musa ukutshaja imoto ixesha elide ngenxa yokuba kulula. Yikhuphe nje xa sele itshajiwe ngokupheleleyo. Indawo yokutshaja ebusika akufuneki ibe ngaphantsi kwe-0℃. Xa utshaja, musa ukuyishiya kude kakhulu ukuze uthintele iingxaki ezingxamisekileyo kwaye ujongane nazo ngexesha elifanelekileyo.
4. Sebenzisa itshaja ekhethekileyo kwiibhetri ze-lithium xa utshaja.
Imakethi izele ziitshaja ezikumgangatho ophantsi. Ukusebenzisa iitshaja ezikumgangatho ophantsi kuya kubangela umonakalo kwibhetri kwaye kubangele nemililo. Musa ukuthenga iimveliso ezixabiso liphantsi nezingenakhuseleko ngexabiso eliphantsi, ingasathethwa ke ngokusebenzisa iitshaja zebhetri ye-lead-acid; ukuba itshaja yakho ayinakusetyenziswa ngokuqhelekileyo, yeka ukuyisebenzisa ngoko nangoko, kwaye ungalahlekelwa ngumfanekiso omkhulu wezinto ezincinci.
5. Nika ingqalelo kubomi bebhetri kwaye uyitshintshe ngexesha elifanelekileyo
Iibhetri zeLithiuminobomi obude. Iinkcukacha ezahlukeneyo kunye neemodeli zinexesha elahlukileyo lobomi. Ukongeza, ngenxa yokusetyenziswa okungafanelekanga kwemihla ngemihla, ubomi bebhetri buqala kwiinyanga ezimbalwa ukuya kwiminyaka emithathu. Ukuba imoto ilahlekelwa ngamandla okanye ubomi bebhetri bufutshane kakhulu, nceda unxibelelane nabasebenzi bokulungisa ibhetri ye-lithium ngexesha ukuze bayilungise.
6. Shiya amandla athile ebusika
Ukuze usebenzise imoto ngokwesiqhelo entwasahlobo yonyaka ozayo, ukuba ibhetri ayisetyenziswanga ixesha elide, khumbula ukuyitshaja ukuya kuthi ga kwi-50%-80%, uyikhuphe emotweni ukuze uyigcine, kwaye uyitshaje rhoqo, malunga kanye ngenyanga. Qaphela: Ibhetri kufuneka igcinwe kwindawo eyomileyo.
7. Beka ibhetri ngokuchanekileyo
Musa ukuntywilisela ibhetri emanzini okanye uyenze imanzi; musa ukufaka ibhetri ngaphezu kweengqimba ezisi-7, okanye ujike indlela ibhetri ejonge kuyo.
Isiphelo
Kwi--20℃, amandla okukhupha iibhetri ze-lithium-ion amalunga ne-31.5% kuphela yaloo bushushu begumbi. Ubushushu bokusebenza kweebhetri zemveli ze-lithium-ion buphakathi kwe--20 kunye ne-+55℃. Nangona kunjalo, kwicandelo leenqwelo-moya, kushishino lomkhosi, kwizithuthi zombane, njl.njl., iibhetri kufuneka zisebenze ngokuqhelekileyo kwi--40℃. Ke ngoko, ukuphucula iipropati zobushushu obuphantsi beebhetri ze-lithium-ion kubaluleke kakhulu. Ewe, iibhetri ye-lithiumIshishini lihlala liphuhla, kwaye izazinzulu ziyaqhubeka nokufunda iibhetri ze-lithium ezinokusetyenziswa kumaqondo obushushu aphantsi ukusombulula iingxaki zabathengi.
