Kwiintlobo ngeentlobo zezicelo, iibhetri ezinomthamo ophezulu zifunwa kakhulu namhlanje.Ezi bhetri zinezicelo ezininzi, ezibandakanya amandla elanga, isithuthi sombane, kunye neebhetri zokuzonwabisa.Iibhetri ze-lead-asidi yayikuphela kwebhetri ephezulu ekhethiweyo kwimarike kude kube yiminyaka embalwa edlulileyo.Umnqweno weebhetri ezisekelwe kwi-lithium uye watshintsha kakhulu kwimarike yangoku, nangona kunjalo, ngenxa yezicelo zabo.

Ibhetri ye-lithium-ion kunye ne-lithium Iron phosphate (LiFePO4) ibhetri igqame phakathi kwabanye kulo mba.Abantu bahlala bebuza malunga nomahluko phakathi kweebhetri ezimbini kuba zisekwe kwi-lithium.

Ngenxa yoko, siza kuhlolisisa ezi bhetri nzulu kwesi siqwenga kwaye sixoxe ngendlela ezahluka ngayo.Ngokufunda malunga nokusebenza kwabo kwizinto ezahlukeneyo, uya kufumana ukuqonda ngakumbi malunga nokuba yeyiphi ibhetri eya kusebenza kakuhle kuwe.Ngaphandle kokuqhubeka, masiqale:

Kutheni iibhetri zeLiFePO4 zingcono:

Abavelisi kumashishini ahlukeneyo bajonga kwi-lithium iron phosphate kwizicelo apho ukhuseleko lungundoqo.Iikhemikhali ezigqwesileyo kunye nokuqina kwe-thermal yipropathi ye-lithium iron phosphate.Kwiindawo ezishushu, le bhetri igcina ukupholisa kwayo.

Kwakhona ayinakutsha xa iphathwa ngokungafanelekanga ngexesha lokuhlawula ngokukhawuleza kunye nokukhutshwa okanye xa kuvela iingxaki zesiphaluka ezimfutshane.Ngenxa yokuxhathisa kwe-phosphate cathode ekutshisweni okanye ekuqhumeni ngexesha lokutshaja okanye ukufudumeza ngokugqithiseleyo kunye nokukwazi kwebhetri ukugcina amaqondo obushushu azolileyo, iibhetri ze-lithium iron phosphate ngokuqhelekileyo azifumani ukubaleka kwe-thermal.

Nangona kunjalo, izibonelelo zokhuseleko ze-lithium-ion battery chemistry zincinci kunezo ze-lithium iron phosphate.Ibhetri inokwethenjelwa ngakumbi ngenxa yobuninzi bayo bamandla aphezulu, okuyi-drawback.Njengoko ibhetri ye-lithium-ion ichaphazeleka ekubalekeni kwe-thermal, iyafudumala ngokukhawuleza ngelixa itshaja.Ukususwa kwebhetri ekugqibeleni emva kokusetyenziswa okanye ukungasebenzi kungenye inzuzo ye-lithium iron phosphate ngokokhuseleko.

Ikhemikhali ye-lithium cobalt dioxide esetyenziswa kwiibhetri ze-lithium-ion ithathwa njengeyingozi kuba inokubeka abantu esichengeni kwiimpendulo zamehlo kunye nolusu.Xa iginyiwe, inokubangela iingxaki zempilo.Ngenxa yoko, iibhetri ze-lithium-ion zifuna iinkxalabo ezikhethekileyo zokulahla.Nangona kunjalo, abavelisi banokulahla i-lithium iron phosphate ngokulula kuba ayinayo inetyhefu.

Ubunzulu bokukhutshwa kweebhetri ze-lithium-ion ukusuka kwi-80% ukuya kwi-95%.Oku kuthetha ukuba kufuneka uhlale ushiya ubuncinci be-5% ukuya kwi-20% yentlawulo (ipesenti echanekileyo iyahluka ngokusekelwe kwibhetri ethile) kwibhetri.Ubunzulu bokukhutshwa kweebhetri ze-lithium iron phosphate (LiFeP04) buphezulu ngokumangalisayo kwi-100%.Oku kubonisa ukuba ibhetri ingakhutshwa ngokupheleleyo ngaphandle komngcipheko wokuyonakalisa.Ibhetri ye-lithium iron phosphate yeyona nto ithandwayo malunga nobunzulu bokuphelelwa.

Yintoni eyona nto ingalunganga yebhetri yeLithium-ion?

Iindleko kunye nokuthembeka kweenkqubo zogcino lwamandla, ezifana nezo zisetyenziswa njengonikezelo lwamandla olugciniweyo okanye ukunciphisa ukuguquguquka kwamandla avelisiweyo ukusuka kwimithombo yamandla ahlaziyekayo, iphenjelelwa kakhulu bubomi bokusebenza kweebhetri.Nangona kunjalo, iibhetri ze-lithium-ion zinemiqobo ebalulekileyo, kubandakanywa nemiphumo yokuguga kunye nokukhusela.

Amandla eebhetri ze-lithium-ion kunye neeseli zingaphantsi kuneebhetri ze-Lithium iron phosphate.Kufuneka balumke bangahlawuliswa kakhulu kwaye bakhululwe ngokugqithisileyo.Ukongeza, kufuneka bagcine umsinga ngaphakathi kwemida eyamkelekileyo.Ngenxa yoko, enye i-drawback yeebhetri ze-lithium-ion kukuba i-circuitry yokukhusela kufuneka yongezwe ukuze kuqinisekiswe ukuba zigcinwe ngaphakathi kweendawo zokusebenza ezikhuselekileyo.

Ngethamsanqa, itekhnoloji yedijithali edityanisiweyo yesekethe yenza kube lula ukudibanisa oku kwibhetri okanye, ukuba ibhetri ayitshintshi, izixhobo.Iibhetri ze-Li-ion zinokusetyenziswa ngaphandle kobuchwephesha obukhethekileyo ngenxa yokufakwa kweesekethe zolawulo lwebhetri.Xa ibhetri igcwaliswe ngokupheleleyo, inokugcinwa itshajiwe, kwaye itshaja iya kuwacima amandla ebhetri.

Iibhetri ze-lithium-ion zineenkqubo zokulawula ibhetri ezakhelwe ngaphakathi ezibeka esweni iinkalo ezahlukeneyo zokusebenza kwazo.Umjikelo wokhuseleko uthintela amandla ombane aphezulu kwiseli nganye ngexesha lokutshaja kuba amandla ombane amaninzi anokwenzakalisa iiseli.Kuba iibhetri zidla ngokuba noqhagamshelo olunye kuphela, zidla ngokuhlawuliswa kuthotho, nto leyo eyandisa umngcipheko wokuba iseli enye ifumane amandla ombane aphezulu kunemfuneko kuba iiseli ezahlukeneyo zinokufuna amanqanaba entlawulo ahlukeneyo.

Inkqubo yokulawula ibhetri ikwagcina umkhondo weqondo lobushushu leseli ukunqanda amaqondo obushushu aphezulu.Uninzi lweebhetri zinexabiso eliphezulu kunye nezithintelo zokukhupha eziphakathi kwe-1°C kunye ne-2°C.Nangona kunjalo, xa itshaja ngokukhawuleza, ezinye ziyafudumala kancinci.

Inyaniso yokuba iibhetri ze-lithium ion ziwohloka ngokuhamba kwexesha yenye yezona zinto zithintelayo zokuzisebenzisa kwizixhobo zabathengi.Oku kuxhomekeke kwixesha okanye ikhalenda, kodwa kukwaxhomekeke nokuba zingaphi na imijikelo yokukhupha ibhetri egqithe kuyo.Rhoqo, iibhetri zinokunyamezela kuphela ama-500 ukuya kwi-1000 imijikelo yokukhupha intlawulo phambi kokuba umthamo wazo uqalise ukwehla.Eli nani liyenyuka njengoko iteknoloji ye-lithium-ion ihambela phambili, kodwa ukuba iibhetri zakhiwe koomatshini, kunokufuneka zitshintshwe emva kwexeshana.

Unokukhetha njani phakathi kweLiFePO4 kunye neebhetri zeLithium-ion?

I-lithium iron phosphate (LiFePO4) iibhetri zineenzuzo ezininzi xa kuthelekiswa neebhetri ze-lithium-ion.Ukukhutshwa okuphuculweyo kunye nokusebenza kakuhle kwentlawulo, ubomi obude, akukho kugcinwa, ukhuseleko olugqithisileyo, kunye nobunzima, ukukhankanya ezimbalwa.Nangona iibhetri zeLiFePO4 zingekho phakathi kwezona zifikelelekayo kwimarike, zezona zibalulekileyo zotyalo-mali lwexesha elide ngenxa yobomi bazo obude kunye nokunqongophala kogcino.

Kwi-80 yepesenti yobunzulu bokukhutshwa, iibhetri ze-lithium iron phosphate zinokuphinda zitshajwe ukuya kumaxesha angama-5000 ngaphandle kokuphazamisa ukusebenza kakuhle.Ubomi bokusebenza kweebhetri ze-lithium iron phosphate (LiFePO4) zinokunyuswa ngokungaqhelekanga.

Ukongeza, iibhetri azinaziphumo zememori, kwaye ungazigcina ixesha elide ngenxa yezinga eliphantsi lokuzikhupha (3% ngenyanga).Ukunyamekela okukhethekileyo kuyadingeka kwiibhetri ze-lithium-ion.Ukuba akunjalo, ubomi babo buya kuncitshiswa ngakumbi.

I-100% umthamo wentlawulo yeebhetri ze-lithium iron phosphate (LiFePO4) iyasebenziseka.Zikwafanelekile kwizicelo ezahlukeneyo ngenxa yentlawulo yazo ekhawulezayo kunye namaxabiso okukhutshwa.Ukusebenza kakuhle kunyuswa, kwaye nakuphi na ukulibaziseka kuyancipha ngokutshaja ngokukhawuleza.Amandla ahanjiswa ngokukhawuleza ngokugqabhuka ngokukhawuleza ngokukhutshwa okuphezulu kwe-pulse currents.

Isisombululo

Umbane welanga unyamezele kwimarike kuba iibhetri zisebenza kakuhle.Kukhuselekile ukuchaza ukuba isisombululo esingcono sokugcina amandla siya kukhokelela kuphela kwindawo ecocekileyo, ekhuselekileyo, kunye nexabiso.Izixhobo zamandla elanga zinokuzuza kakhulu ekusebenziseni i-lithium iron phosphate kunye neebhetri ze-lithium-ion.

Nangona kunjalo,LiFePO4iibhetri zinezibonelelo ezininzi kubo bobabini abathengi kunye nabathengisi.Utyalo-mali kwizikhululo zamandla eziphathwayo ngeebhetri ze-LiFePO4 lukhetho oluhle ngenxa yokusebenza kwazo okuphezulu, ubomi obude, kunye nokuncipha kweziphumo zokusingqongileyo.
