Uphuhliso lwamva nje kwiibhetri zeState-Solid ziiNkampani ezili-10 eziPhezulu zeLithium-ion zeHlabathi

Ngo-2024, ukhuphiswano lwehlabathi jikelele lweebhetri zamandla luqalisile ukumila. Idatha yoluntu ekhutshwe ngoJulayi 2nd ibonisa ukuba ukufakwa kwebhetri yamandla ehlabathi kufikelele kwi-285.4 GWh epheleleyo ukususela ngoJanuwari ukuya kuMeyi kulo nyaka, okuphawula ukukhula kwe-23% ngonyaka.

Iinkampani ezilishumi eziphezulu ezikuluhlu zezi: CATL, BYD, LG Energy Solution, SK Innovation, Samsung SDI, Panasonic, CALB, EVE Energy, Guoxuan High-Tech, kunye neXinwanda. Iinkampani zebhetri zaseTshayina ziyaqhubeka nokuhlala kwizikhundla ezithandathu kwezilishumi eziphezulu.

Phakathi kwabo, ukufakwa kwebhetri yamandla eCATL kwafikelela kwi-107 GWh, kubalwa i-37.5% yesabelo semarike, ukukhusela isikhundla esikhokelayo ngenzuzo epheleleyo. I-CATL ikwayinkampani kuphela emhlabeni wonke ukuba idlule i-100 GWh yofakelo. Ufakelo lwebhetri yamandla e-BYD lufikelele kwi-44.9 GWh, indawo yesibini ngesabelo semarike ye-15.7%, enyuke ngepesenti ezi-2 zeepesenti xa kuthelekiswa neenyanga ezimbini ezidlulileyo. Kummandla weebhetri zelizwe eliqinileyo, imephu yendlela ye-CATL yetekhnoloji ixhomekeke ikakhulu kwindibaniselwano yesimo esiqinileyo kunye nemathiriyeli yesulfide, ejolise ekufumaneni ubuninzi bamandla obuyi-500 Wh/kg. Okwangoku, i-CATL iyaqhubeka nokutyalomali kwintsimi yeebhetri eziqinileyo kwaye ilindele ukufezekisa imveliso encinci ye-2027.

Ngokuphathelele i-BYD, imithombo yemarike ibonisa ukuba banokuthatha i-roadmap yezobuchwepheshe equkethe i-nickel ternary (i-crystal eyodwa) cathodes, i-silicon-based anodes (ukwandiswa okuphantsi), kunye ne-sulfide electrolytes (i-halides edibeneyo). Umthamo weseli ungadlula i-60 Ah, kunye nobunzima obucacileyo bamandla obuyi-400 Wh / kg kunye ne-volumetric energy density ye-800 Wh / L. Ubuninzi bamandla bebhetri, ekwaziyo ukugqobhoza okanye ukufudumeza, bunokugqithisa i-280 Wh/kg. Ixesha lokuvelisa ngobuninzi liphantse lifane nemarike, kunye nemveliso encinci elindeleke ngo-2027 kunye nokukhuthazwa kweemarike ngo-2030.

I-LG Energy Solution ngaphambili ibonise ukuqaliswa kweebhetri ezisekelwe kwi-oxide-based solid-state ngo-2028 kunye ne-sulfide-based based solid-state iibhetri ngo-2030. Uhlaziyo lwamva nje lubonisa ukuba i-LG Energy Solution ijolise ekuthengiseni iteknoloji yebhetri eyomileyo ngaphambi kwe-2028, enokunciphisa iindleko zokuvelisa ibhetri nge-17% -30%.

I-SK Innovation iceba ukugqiba uphuhliso lwe-polymer oxide composite iibhetri ze-slid-state kunye ne-sulfide i-solid-state ibhetri ngo-2026, kunye ne-industrialization ejoliswe kwi-2028. Okwangoku, baseka iziko lophando lwebhetri e-Daejeon, Chungcheongnam-do.

I-Samsung SDI isanda kwazisa isicwangciso sayo sokuqalisa ukuveliswa kobuninzi beebhetri ze-slid-state kwi-2027. Inxalenye yebhetri abasebenza kuyo iya kufezekisa ubuninzi bamandla we-900 Wh / L kwaye ibe nexesha lokuphila ukuya kwi-20 iminyaka, ivumela i-80% ukutshaja kwimizuzu eyi-9.

I-Panasonic ibibambisene neToyota ngo-2019, ijolise ekuguquleni iibhetri zombuso oqinileyo ukusuka kwinqanaba lovavanyo ukuya kushishino. Ezi nkampani zimbini ziphinde zaseka ishishini lebhetri eliqinileyo elibizwa ngokuba yiPrime Planet Energy & Solutions Inc. Nangona kunjalo, akukabikho luhlaziyo lulolunye ngoku. Nangona kunjalo, iPanasonic ngaphambili yabhengeza izicwangciso ngo-2023 zokuqalisa imveliso yebhetri yelizwe eliqinileyo ngaphambi kowama-2029, eyona nto isetyenziselwa ukusetyenziswa kwinqwelomoya engaphathwanga.

Zimbalwa iindaba zakutsha nje malunga nenkqubela phambili ye-CALB kwicandelo leebhetri zombuso oqinileyo. Kwikota yesine kulo nyaka uphelileyo, i-CALB yathi kwinkomfa yamaqabane ehlabathi jikelele ukuba iibhetri zabo ezizii-semi-solid-state ziza kufakwa kwiimoto zodidi lwangaphandle olutofotofo kwikota yesine ka-2024. Ezi bhetri zinokufikelela kumgama oziikhilomitha ezingama-500 ngentlawulo yemizuzu eyi-10, kwaye ubungakanani bazo obukhulu bunokufikelela kwi-1000 km.

Usekela Mlawuli we-EVE Energy weZiko loPhando oluPhakathi, uZhao Ruirui, utyhile uphuhliso lwamva nje lweebhetri eziqinileyo ngoJuni walo nyaka. Kuxelwe ukuba i-EVE Energy ilandela i-technology roadmap ebandakanya i-sulfide kunye ne-halide eqinile ye-electrolytes. Baceba ukusungula iibhetri ezipheleleyo zelizwe ngo-2026, ekuqaleni begxile kwiimoto zombane ezixutywe.

I-Guoxuan High-Tech sele ikhuphe i-"Jnshi Battery," ibhetri yesimo esipheleleyo esisebenzisa i-sulfide electrolytes. Iqhayisa ngamandla oxinzelelo lokuya kuthi ga kwi-350 Wh/kg, ukodlula iibhetri zeternary eziqhelekileyo ngaphezu kwe-40%. Ngomthamo we-semi-solid-state yemveliso ye-2 GWh, i-Guoxuan High-Tech ijolise ekuqhubeni iimvavanyo ezincinci kwimoto yebhethri epheleleyo ye-Jinshi yelizwe eliqinileyo ngo-2027, ngenjongo yokuphumeza imveliso yobuninzi ngo-2030 xa ikhonkco loshishino lusekwe kakuhle.

I-Xinwanda yenze udizo lwayo lokuqala oluneenkcukacha esidlangalaleni malunga nenkqubela phambili kwiibhetri ezipheleleyo zelizwe ngoJulayi walo nyaka. I-Xinwanda ichaze ukuba ngokwenziwa ngokutsha kwetekhnoloji, ilindele ukunciphisa iindleko zeebhetri ze-polymer-based solid-state ukuya kwi-2 yuan/Wh ngo-2026, ekufutshane neendleko zeebhetri ze-lithium-ion zemveli. Baceba ukufezekisa ukuveliswa kweebhetri ezipheleleyo zelizwe ngo-2030.

Ukuqukumbela, iinkampani ezilishumi eziphezulu zehlabathi ze-lithium-ion ziphuhlisa ngokukhutheleyo iibhetri zombuso oqinileyo kwaye zenza inkqubela phambili enkulu kule ndawo. I-CATL ikhokela ipakethe ngokugxila kwi-solid-state kunye ne-sulfide materials, ijolise kubuninzi bamandla we-500 Wh / kg. Ezinye iinkampani ezifana ne-BYD, i-LG Energy Solution, i-SK Innovation, i-Samsung SDI, i-Panasonic, i-CALB, i-EVE Energy, i-Guoxuan High-Tech, kunye ne-Xinwanda nazo zineendlela zazo zetekhnoloji kunye namaxesha ophuhliso lwebhetri yelizwe. Umdyarho weebhetri zombuso oqinileyo uyaqhubeka, kwaye ezi nkampani zizama ukufezekisa urhwebo kunye nemveliso enkulu kwiminyaka ezayo. Ukuqhubela phambili okuchulumancisayo kunye nokuphumelela kulindeleke ukuba kuguqule ishishini lokugcina amandla kwaye kuqhube ukwamkelwa okubanzi kweebhetri zombuso oqinileyo.
