Iibhetri ze-LFP kunye ne-NMC njengoKhetho oluBalulekileyo: iibhetri ze-Lithium Iron Phosphate (LFP) kunye neebhetri ze-Nickel Manganese Cobalt (NMC) zimbini ezikhuphisanayo ezibalaseleyo kummandla wogcino lwamandla elanga. Ezi teknoloji ezisekelwe kwi-lithium-ion ziye zafumana ukuqaphela ukusebenza kwazo, ixesha elide, kunye nokuguquguquka kwizicelo ezahlukeneyo. Nangona kunjalo, zihluke kakhulu ngokubhekiselele kwimichiza yazo, iimpawu zokusebenza, iimpawu zokhuseleko, impembelelo yokusingqongileyo, kunye nokuqwalaselwa kweendleko.Ngokuqhelekileyo, iibhetri ze-LFP ziyakwazi ukugcina amawaka emijikelezo ngaphambi kokuba zifune ukutshintshwa, kwaye zinobomi obuhle kakhulu bomjikelezo. Ngenxa yoko, iibhetri ze-NMC zikholisa ukuba nobomi obufutshane bomjikelo, obuhlala kuphela amakhulu ambalwa emijikelo phambi kokuwohloka. Ukubaluleka kokuGcina amandla kuMbane weSola Umtsalane wehlabathi jikelele ngemithombo yamandla ahlaziyekayo, ngakumbi amandla elanga, kukhokelele kwinguqu ephawulekayo ebhekiselele kwiindlela ezicocekileyo nezizinzileyo zokuvelisa umbane. Iiphaneli zelanga sele ziyinto eqhelekileyo kuphahla lwezindlu kunye neefama ezithe gabalala zelanga, zisebenzisa amandla elanga ukuvelisa umbane. Nangona kunjalo, indalo engaqhelekanga yokukhanya kwelanga inika umngeni - amandla aveliswa emini kufuneka agcinwe ngokufanelekileyo ukuze asetyenziswe ngexesha lasebusuku okanye lamaxesha okusibekela. Kulapho iinkqubo zokugcina amandla, ngokukodwa iibhetri, zidlala indima ebalulekileyo. Umsebenzi weebhetri kwiiNkqubo zeSolar Energy Iibhetri zisisiseko senkqubo yangoku yamandla elanga. Basebenza njengekhonkco phakathi kokuveliswa kunye nokusetyenziswa kwamandla elanga, ukuqinisekisa ukunikezelwa kwamandla okuthembekileyo kunye nokungaphazanyiswa. Ezi zisombululo zokugcina azisebenzi jikelele; endaweni yoko, ziza kwiintlobo ezahlukeneyo zeekhemikhali kunye nolungelelwaniso, nganye inezinto zayo eziluncedo kunye nezingeloncedo. Eli nqaku liphonononga uhlalutyo lokuthelekisa iibhetri ze-LFP kunye ne-NMC kumxholo wokusetyenziswa kwamandla elanga. Injongo yethu kukubonelela abafundi ngolwazi olubanzi lweenzuzo kunye nokungalunganga okuhambelana nohlobo ngalunye lwebhetri. Ekupheleni kolu phando, abafundi baya kuxhotyiselwa ukwenza ukhetho olufundisiweyo xa bekhetha iteknoloji yebhetri yeeprojekthi zabo zamandla elanga, kuthathelwa ingqalelo iimfuno ezithile, imida yohlahlo lwabiwo-mali, kunye nokuqwalaselwa kokusingqongileyo. Ukubamba Ukuma kwebhetri Ukuwuqonda ngokwenyani umahluko phakathi kwebhetri ye-LFP kunye ne-NMC, kubalulekile ukukhangela kumbindi wezixokelelwano zogcino lwamandla-ukwakheka kweekhemikhali zazo. Iibhetri ze-lithium iron phosphate (LFP) zisebenzisa i-iron phosphate (LiFePO4) njengesixhobo se-cathode. Olu qulunqo lweekhemikhali lubonelela ngokuzinza kunye nokuchasana nobushushu obuphezulu, okwenza iibhetri ze-LFP zithinteke kakhulu ekubalekeni kwe-thermal, inkxalabo ebalulekileyo yokhuseleko. Ngokwahlukileyo, iibhetri ze-Nickel Manganese Cobalt (NMC) zidibanisa i-nickel, i-manganese, kunye ne-cobalt ngomlinganiselo ohlukeneyo kwi-cathode. Lo mxube wekhemikhali ubetha ulungelelwano phakathi koxinano lwamandla kunye nemveliso yamandla, okwenza iibhetri ze-NMC zibe lukhetho oludumileyo kuluhlu olubanzi lwezicelo. Iiyantlukwano eziphambili kwiKhemistri Njengoko sihlolisisa ngakumbi kwikhemistri, ukwahlukana kuya kubonakala. Iibhetri ze-LFP zibeka phambili ukhuseleko kunye nokuzinza, ngelixa iibhetri ze-NMC zigxininisa urhwebo phakathi komthamo wokugcina amandla kunye nokukhutshwa kwamandla. Lo mahluko usisiseko kwikhemistri kubeka isiseko sokuphononongwa ngakumbi kweempawu zabo zokusebenza. Amandla kunye noXinano lwaMandla Iibhetri zeLithium Iron Phosphate (LFP) zidume ngobomi bazo bomjikelo owomeleleyo kunye nozinzo olukhethekileyo lobushushu. Nangona banokuba namandla angaphantsi kwamandla xa kuthelekiswa nezinye iikhemistri ze-lithium-ion, iibhetri ze-LFP zigqwesa kwiimeko apho ukuthembeka kwexesha elide kunye nokhuseleko kubaluleke kakhulu. Ukukwazi kwabo ukugcina ipesenti ephezulu yomthamo wabo wokuqala phezu kwemijikelo emininzi yokukhupha intlawulo kubenza balungele iinkqubo zokugcina amandla elanga ezenzelwe ubomi obude. Iibhetri zeNickel Manganese Cobalt (NMC) zibonelela ngamandla oxinaniso oluphezulu, nto leyo eyenza ukuba zikwazi ukugcina amandla amaninzi kwindawo exineneyo. Oku kwenza ukuba iibhetri ze-NMC zibe nomtsalane kwizicelo ezinobukho bendawo enyiniweyo. Nangona kunjalo, kubalulekile ukuqwalasela ukuba iibhetri ze-NMC zinokuba nobomi obufutshane bomjikelo xa kuthelekiswa neebhetri ze-LFP phantsi kweemeko ezifanayo zokusebenza. Umjikelo woBomi kunye nokunyamezela Iibhetri ze-LFP zaziwa ngokuqina kwazo. Ngobomi obuqhelekileyo bomjikelo ukusuka kwi-2000 ukuya kwi-7000 cycles, zenza ngcono ezinye iikhemistri ezininzi zebhetri. Olu kunyamezela luyinzuzo ebalulekileyo kwiinkqubo zamandla elanga, apho imijikelo yokukhutshwa rhoqo kwentlawulo ixhaphakile. Iibhetri ze-NMC, nangona zibonelela ngenani elihloniphekileyo lemijikelo, zinokuba nobomi obufutshane xa kuthelekiswa neebhetri ze-LFP. Ngokuxhomekeke kwiipateni zokusetyenziswa kunye nokugcinwa, iibhetri ze-NMC zikholisa ukunyamezela phakathi kwe-1000 ukuya kwi-4000 yeejiyile. Lo mba ubenza bafaneleke ngcono kwizicelo ezibeka phambili uxinano lwamandla ngaphezu kokuqina kwexesha elide. UFanelo lokuTshaja kunye nokuKhutshwa Iibhetri ze-LFP zibonisa ukusebenza kakuhle okugqwesileyo kokubini ukutshaja kunye nokukhupha, zihlala zidlula i-90%. Oku kusebenzayo okuphezulu kubangela ukulahlekelwa kwamandla amancinci ngexesha lokutshaja kunye nokukhupha inkqubo, igalelo kwinkqubo esebenzayo yamandla elanga. Iibhetri ze-NMC zikwabonisa imfezeko entle ekutshajiseni nasekukhupheni, nangona zisebenza kancinci kancinci xa zithelekiswa neebhetri ze-LFP. Nangona kunjalo, uxinaniso lwamandla oluphezulu lweebhetri ze-NMC lusenokuba negalelo ekusebenzeni kakuhle kwenkqubo, ngakumbi kwizicelo ezineemfuno zamandla ezahlukeneyo. Iingqwalasela zoKhuseleko nokusiNgqongileyo Iibhetri ze-LFP zidume ngokhuseleko lwazo oluqinileyo. Ikhemikhali ye-iron phosphate abayisebenzisayo ayichaphazeleki kancinci ekubalekeni kwe-thermal kunye nokutsha, ibenze ibe lukhetho olukhuselekileyo lwezicelo zokugcina amandla elanga. Ngaphezu koko, iibhetri ze-LFP zihlala zibandakanya iimpawu zokhuseleko oluphezulu ezifana nokujongwa kwe-thermal kunye ne-cutoff mechanisms, ngakumbi ukomeleza ukhuseleko lwazo. Iibhetri ze-NMC zikwadibanisa iimpawu zokhuseleko kodwa zinokuthwala umngcipheko ophezulu kancinane wemiba yobushushu xa kuthelekiswa neebhetri zeLFP. Nangona kunjalo, ukuqhubela phambili okuqhubekayo kwiinkqubo zolawulo lwebhetri kunye neeprothokholi zokhuseleko ziye zenza ukuba iibhetri ze-NMC zikhuseleke ngokuqhubekayo. Impembelelo yokusingqongileyo ye-LFP kunye neebhetri ze-NMC Iibhetri ze-LFP ngokubanzi zithathwa njenge-eco-friendly ngenxa yokusebenzisa kwazo izinto ezingenayo ityhefu kunye nezinto ezininzi. Ubomi babo obude kunye nokuphinda zisetyenziswe kwakhona kunegalelo ekuzinzeni kwazo. Nangona kunjalo, kubalulekile ukuqwalasela iziphumo zokusingqongileyo zokumbiwa kwemigodi kunye nokulungiswa kwe-iron phosphate, enokuthi ibe neziphumo zendawo yokuhlala. Iibhetri ze-NMC, nangona zixinene kwaye zisebenza kakuhle, zihlala zine-cobalt, imathiriyeli enenkxalabo yokusingqongileyo kunye nokuziphatha ebotshelelwe kwimigodi kunye nokusetyenzwa kwayo. Iinzame ziyaqhubeka ukunciphisa okanye ukuphelisa i-cobalt kwiibhetri ze-NMC, ezinokuphucula iprofayili yazo yendalo. Uhlalutyo lweendleko Iibhetri ze-LFP zinexabiso eliphantsi xa kuthelekiswa neebhetri ze-NMC. Oku kufikeleleka kunokuba yinto ekhangayo kwiiprojekthi zamandla elanga kunye nokunciphisa uhlahlo lwabiwo-mali. Iibhetri ze-NMC zinokuba neendleko eziphezulu zangaphambili ngenxa yoxinano lwamandla aphezulu kunye nobuchule bokusebenza. Nangona kunjalo, kubalulekile ukuqwalasela amandla abo obomi bomjikelo omde kunye nokonga amandla ekuhambeni kwexesha xa bevavanya iindleko zangaphambili. Iindleko zizonke zoBunini Ngelixa iibhetri ze-LFP zinexabiso eliphantsi lokuqala, iindleko zabo zizonke zobunini phezu kwexesha lokuphila kwenkqubo yamandla elanga zinokukhuphisana okanye zingaphantsi kuneebhetri ze-NMC ngenxa yobomi bazo obude bomjikelo kunye neemfuno zokugcinwa okuphantsi. Iibhetri ze-NMC zisenokufuna ukutshintshwa rhoqo kunye nokugcinwa kwazo kubomi bazo bonke, okuchaphazela ixabiso elipheleleyo lobunini. Nangona kunjalo, ukwanda koxinano lwamandla kunokulinganisa ezinye zezi ndleko kwizicelo ezithile.
