Iinkqubo zesingxobo zizuza kwiiprothokholi zokuhlola okubonwayo: abasebenzi bolondolozo abaqeqeshelwe ukuqaphela ukunyuka kobukhulu obuyi-5mm kunokuthintela i-80% yokusilela ebaleni ngokutshintshwa okukhawulezileyo. Ii-OEM zeemoto ngoku zichaza iinkqubo zombono ezizenzekelayo zokuhlola ipakethe yebhetri, ukufumanisa ukudumba kwengxowa efihlakeleyo okungenakubonwa ngabantu ababukeleyo.

Ukufunwa komgangatho kwahlula ukusasazwa okuyimpumelelo kwezo zinengxaki. Inqanaba -1 abavelisi beeseli{3}}CATL, LG Energy Solution, Samsung SDI, BYD{10}}bagcina ulawulo oluluqilima lomgangatho oluneziphene ezingaphantsi kwama-50 amalungu kwisigidi ngasinye. Ababoneleli besibini banokulithoba ixabiso le-20-30% kodwa babonise ukusilela ngokuphindwe ka-10-100 ngaphezulu. Umvelisi wezixhobo zeshishini le-B2B utshintshele kubaxhasi bengxowa ephantsi ngexabiso eliphantsi ukunciphisa iindleko zebhetri i-$15 ngeyunithi, kuphela ukufumana i-4% yemilinganiselo yokungaphumeleli kwewaranti evelisa i-$ 200,000 kwiindleko zokubuyisela kunye nomonakalo wodumo. Ukubuyela kubaboneleli bepremiyamu kubuyiselwe ukuthembeka kwiintlawulo ezamkelekileyo zeendleko.

Zombini iifomati zisebenzisa i-lithium -ikhemistri ye-ion enokuphinda ibuye umva i-electrochemical reaction. Ngexesha lokukhutshwa, i-lithium ion isuka kwi-anode (ngokuqhelekileyo i-graphite) nge-electrolyte engamanzi ukuya kwi-cathode (ii-oxide zetsimbi ezahlukeneyo). Ukusebenzisa amandla ombane angaphandle kubuyisela umva oku kuhamba, ukubuyisela amandla ekhemikhali. Ngokungafaniyo neebhetri ze-lithium eziphambili zisebenzisa i-lithium metal anode ecocekileyo engakwaziyo ukubuyisela umva ngokukhuselekileyo, i-lithium-iiseli ze-ion zidibanisa i-lithium kwizinto ezizinzile zokusingatha{5}}ivumela i-500-5,000 ye-recharge cycles ngokuxhomekeke kwikhemistri kunye neemeko zokusebenza.

Ukutshintsha ngokuthe ngqo akufane kwenzeke ngenxa yokungahambelani kombane. Nokuba ubungakanani bomzimba buhambelana, iiseli zeprismatic kunye nepouch zibonisa iijika zombane ezahlukeneyo, ukumelana kwangaphakathi, kunye neemfuno zoomatshini. Iisistim zolawulo lwebhetri ezilungelelaniswe enye ifomathi zisenokuphatha kakubi enye, zibeke emngciphekweni wokutsaliswa kakhulu, ngaphezulu{2}}ukukhupha, okanye iziganeko zobushushu. Utshintsho lwefomathi oluyimpumelelo lufuna ukuyilwa ngokutsha kwepakethi egqibeleleyo kuquka uhlengahlengiso lwe-BMS, uhlengahlengiso lwendawo ebiyelweyo ngoomatshini, kunye novavanyo olubanzi lokuqinisekisa.

Phantsi kweemeko zokusebenza ezifanayo, iiseli zeprismatic zihambisa 25-40% umjikelo omde wobomi-3,000-4,000 imijikelo ngokuchasene ne-2,000-3,000 yezinye iipouch. Olu ncedo luvela kulawulo oluphezulu lwe-thermal kunye nokukhuselwa komatshini okuthintela ukuqokelelwa komonakalo wangaphakathi. Nangona kunjalo, uyilo olufanelekileyo lwe-thermal kunye noomatshini lunokuzisa ubomi beeseli zesingxobo ngaphakathi kwe-10-15% yeeprismatic equivalents. Ubomi bokwenyani behlabathi buxhomekeke ngakumbi kwiimeko zokusebenza (ubushushu, iprotocol yentlawulo, ubunzulu bokukhutshwa) kunefomathi yodwa.

Iiprofayile zokhuseleko ziyahluka endaweni yokubeka ngokwemigangatho. Iiseli zePrismatic ziqulathe ukusilela ngaphakathi kwezindlu eziqinileyo kodwa zenza uxinzelelo oluphezulu lwangaphakathi ngexesha leziganeko ezishushu{1}}ezinokukhokelela ekungeneni ngobundlobongela. Iiseli zesingxobo zisilela ngakumbi ngokudumba ngokuthe ngcembe, zibonelela ngesilumkiso esibonakalayo, kodwa ukupakishwa kwazo okubhetyebhetye akuniki khuselo lwangaphakathi lokuhlatywa. Iinkqubo ezinobunjineli ngokufanelekileyo zifezekisa ukhuseleko oluthelekisekayo kungakhathaliseki ukuba luhlobo luni na ngolawulo olufanelekileyo lwe-thermal, uyilo lomatshini, kunye nokukhusela inkqubo yokulawula ibhetri.

Iiprayorithi zesicelo qhuba ukhetho lwefomathi. Ii-smartphones zilungiselela ubungqingqwa kunye nobunzima kwindawo ekhuselekileyo yomatshini{1}}iiseli zengxowa ziyagqwesa kwezi nqobo zokugweba. Izithuthi zombane zibeka phambili ubomi bomjikelo, uzinzo lwe-thermal, kunye nokuqina koomatshini ngaphezulu kogcino lobunzima obuphakathi{3}}iiseli zeprismatic zinceda ngcono ezi mfuno. Nangona kunjalo, izinto ezingaphandle zikhoyo: ezinye ii-EVs (izahlukano ezithile zeNissan Leaf) zithumela ngempumelelo iiseli zesingxobo, ngelixa ii-smartphones ezihexayo zinokukhankanya iiseli ezincinci zeprismatic zokomelezwa kokuqina.

Ukukhetha ifomathi kuphembelela i-15-30% yexabiso lilonke lenkqubo yebhetri ngaphaya kweendleko zeseli ekrwada. Iiseli zePrismatic zibiza i-15-20% ngaphezulu nge-kilowatt-yure kodwa zifuna izinto ezilula zokuxhasa oomatshini. Iiseli zesingxobo zonga kwiindleko zeeseli kodwa zifuna iinkqubo zoxinzelelo eziphucukileyo kunye nolawulo lobushushu. Kwinqanaba lenkqubo, ukungafani kweendleko kuncinci ukuya kwi-5-15% kuxhomekeke kumthamo wemveliso kunye neemfuno ze-thermal. Iimpembelelo zokwenziwa komsebenzi kunye nokuthembeka zikholisa ukodlula ukuqwalaselwa kweendleko ngokuthe ngqo ekukhetheni ifomathi.

Iiseli zePrismatic kunye neepouch zimele iindlela zokupakisha ezahlukileyoye-lithium-ikhemistri ye-ion{1}}oonokrwece ababuxande obungqongqo ngokuchasene nelaminates ezibhetyebhetye{2}}nganye ikhulisa iiparamitha zokusebenza ezahlukeneyo kunokumela ubuchwephesha obuphezulu/abangaphantsi

Uxinaniso lwamandla luthanda ukuyilwa kweengxowa(174 Wh/kg) ngaphezu kwezinto ezizezinye zeprismatic (157-165 Wh/kg), ukuguqulela kwi-10-15% yokonga ubunzima obubalulekileyo kwi-electronics ephathekayo kunye nezicelo ze-aerospace

Izibonelelo zolawulo lwe-Thermal zezofomathi zeprismaticngokusebenzisa iqokobhe lesinyithi lokulahla ubushushu, okwenza ukuba{0}ukukhutshwa kwamandla aphezulu kwimoto nakwimizi-mveliso apho iiseli zengxowa zifuna ubunzulu boyilo lokupholisa.

Ulwakhiwo lweendleko zohluka ngokweqhinga: iiseli zesingxobo zinikezela nge-15-20% yeendleko zokwenziwa ezisezantsi kodwa zifuna inkqubo enkulu{2}}inqanaba lotyalo-mali kwinkxaso yomatshini kunye neendleko zenkqubo yolawulo olushushu zidibana ngaphakathi kwe-5-15% kwisikali

Iimfuno zesicelo ziqhuba ukhetho lwefomathi elolonakuzo zonke imilinganiselo emithandathu yesigqibo: iprofayile yamandla, imeko-bume yomatshini, imiqobo yendawo, umthamo wemveliso, iimfuno zobomi bomjikelo, kunye nemimiselo yokhuseleko-akukho ifomathi "egqwesileyo" jikelele ekhoyo kuzo zonke iimeko zokusetyenziswa.
