Idatha yamva nje ekhutshwe yi-China Automobile Industry Innovation Alliance ibonisa ukuba umthamo opheleleyo webhetri yasekhaya yasekhaya ngo-2020 yi-63.6GWh, ukunyuka kwe-2.3% unyaka nonyaka. Phakathi kwazo, umthamo webhetri ye-ternary yi-38.9GWh, ibalwa kwi-61.1% yomthwalo opheleleyo, kunye nokuhla okunyukayo kwe-4.1% unyaka nonyaka; Umthamo ofakiweyo Umthamo wawuyi-24.4GWh, ubalwa kwi-38.3% yomthamo ofakiweyo uwonke, ukunyuka okunyukayo ngama-20.6% unyaka nonyaka. Isantya sokubuyisela i-lithium iron phosphate ibonakala.

Ukususela kumbono wokhuphiswano lweemarike, i-CATL ine-50% yesabelo semarike kwimarike yasekhaya, i-BYD ine-14.9%, kunye ne-AVIC Lithium kunye ne-Guoxuan Hi-Tech i-akhawunti ngaphezu kwe-5%. I-CATL ibekwe kwindawo yokuqala kurhwebo lwehlabathi iminyaka emine ilandelelana, ibalelwa malunga ne-24.8% yesabelo semarike. I-LG Chem yaseMzantsi Korea yenza i-22.6% yemarike; I-Panasonic ibalwa kwi-18.3%; I-BYD, i-Samsung SDI kunye ne-SKI zibalwa kwi-7.3%, i-5.9% kunye ne-5.1%, ngokulandelanayo.

(3) Ukuhanjiswa kwempahla

I-Panasonic Corporation yaseJapan ngumthengisi oyintloko weTesla kwiimarike zangaphandle, kwaye kamva wazisa i-CATL kunye ne-LG Chem. Kukho ababoneleli bebhetri basekhaya abadala amandla amatsha. Iibhetri zemoto ze-NiO zibonelelwa ngokwahlukeneyo nguNingde Times, i-Ideal Auto inikezelwa yi-Ningde Times kunye ne-BYD, i-Xiaopeng Motors ibonelelwa yi-Ningde Times, i-Yiwei Lithium Energy, njl., kunye ne-Weimar Motors kunye ne-Hezhong New Energy ababoneleli bebhetri bathe saa.

Iindaba zamva nje malunga nezabelo ze-A.

Amaxesha eNingde: Ukusukela ngoFebruwari ka-2020, phantse i-100 leebhiliyoni zotyalo-mali ebhetri entsha yongeziweyo, kwaye i-300GWh yomthamo omtsha wemveliso yongeziwe. Kwi-2025, ibhetri yamandla yehlabathi iya kungena kwixesha le-TWh, kwaye i-CATL, njengenkokeli yehlabathi kwiibhetri zamandla, kulindeleke ukuba ibeke kuqala ngokumalunga nomthamo ofakiweyo kunye nomthamo wokuvelisa.

Ngomhla we-19 kaJanuwari, i-CATL yabhengeza amalungelo awodwa omenzi weebhetri ezimbini. “Indlela yokulungiselela i-electrolyte eqinile”, ukusabalalisa i-lithium precursor kunye ne-athomu ye-athomu ephakathi kwi-solvent ye-organic ukwenza umxube wokuqala wokuphendula; ukusasaza i-borate kwi-solvent ye-organic ukwenza isisombululo esilungisiweyo. Umxube wokuqala wokuphendula uxutywe kunye nesisombululo sokuguqulwa, kwaye imveliso yokuqala ifunyenwe emva kokumisa. I-electrolyte eqinileyo ifumaneka kwimveliso yokuqala emva kokusila, ucinezelo olubandayo, kunye nonyango lobushushu. Indlela yokulungiselela ilungelo elilodwa lomenzi wechiza inokuphucula ngokubonakalayo i-conductivity ye-electrolyte eyomeleleyo, eluncedo ekunyuseni ukuxinana kwamandla kuzo zonke iibhetri zesimo esomeleleyo. “I-sulfide eqinile ye-electrolyte sheet kunye nendlela yokuyilungisa”, i-sulfide electrolyte material idityaniswe ne-boron element efakwe kwizinto ze-sulfide electrolyte, kunye nokuphambuka okuhambelanayo (B0. b100) / B0 ngokungenamthetho kumphezulu wephepha le-electrolyte. ukutenxa isalamane phakathi koxinzelelo lwe-boron ubunzima be-B0 yesikhundla kunye noxinzelelo lwe-boron ubunzima B100 100 μm kude nendawo ingaphantsi kwe-20%, enokunciphisa ngokufanelekileyo isiphumo sokubophelela kwee-anion kwii-ion ze-lithium kunye nokuphucula amandla okuhambisa i-ion lithium. Ngexesha elifanayo, ukufana kwe-doping kunye ne-conductivity kuphuculwe, i-impedance ye-interface iyancitshiswa, kwaye ukusebenza komjikelo webhetri kuphuculwe.

Byd: Kutshanje, I-Ofisi State Intellectual Property yapapasha inani patent kwibala iibhetri Byd, kubandakanywa “cathode izinto kunye nendlela yayo yokulungiselela, kunye nebhetri-state lithium eqinileyo”. Le patent ibonelela ngezinto ze-cathode kunye neendlela zokulungiselela ibhetri ye-lithium eqinile. Izinto ezilungileyo ze-electrode zinokwakha i-lithium ion ishaneli yokuhambisa i-ion kunye nokuhanjiswa kwe-electron ngaxeshanye, nto leyo iphucula kakhulu umthamo, i-lap yokuqala ye-coulombic ukusebenza kakuhle, ukusebenza komjikelo, kunye nokusebenza okuphezulu kwebhetri ye-lithium yelizwe eliqinileyo. I-electrolyte eqinile kunye nendlela yayo yokulungiselela kunye nebhetri ye-lithium eqinile “ijolise ekusombululeni iingxaki zokuxinana kwamandla aphantsi kunye nokhuseleko olubi lwebhetri ekhoyo ye-electrolyte eqinile ye-lithium. “Ijeli kunye nendlela yayo yokuyilungisa” ibonisa ukuba i-BYD ikwintsimi yeebhetri ezizii-semi-soli Inkqubela yenziwe.

I-Guoxuan Hi-Tech: I-Lithium iron phosphate 210Wh/kg ibhetri ethambileyo ye-monomer kunye nebhetri ye-JTM I-Lithium iron phosphate 210Wh/kg ibhetri ye-monomer ethambileyo ziimveliso ezinoxinano olukhulu lwamandla kwinkqubo ye-lithium iron phosphate ehlabathini, eziphuhliswe ngokuzimeleyo. Ukusebenza okuphezulu kwe-iron phosphate Ngezinto ze-lithium, izinto ze-silicon anode ezinobunzima obuphezulu begram kunye neteknoloji yangaphambili ye-lithium, ubuninzi bamandla be-monomer bufikelele kwinqanaba le-ternary NCM5 inkqubo. Kwi-JTM, u-J ngundoqo wekhoyili kwaye uM yimodyuli. Izinto zebhetri zale mveliso zenziwe zalula kakhulu, inkqubo yokuvelisa ilula kakhulu, ukusebenza kwebhetri kuphuculwe kakhulu, ixabiso elipheleleyo liyancipha kakhulu, kwaye ukuguquguquka kwebhetri yepakethi kuphuculwe kakhulu.

Iprojekthi ye-MEB ephuhliswe ngokudibeneyo kunye neVolkswagen ibhekiselele kuyilo lwemodyuli ye-MEB eqhelekileyo ye-terpolymer kunye nenkqubo yekhemikhali ye-iron-lithium, kwaye kulindeleke ukuba ifezekise imveliso kunye nokubonelela ngobuninzi ngo-2023.

I-Xinwangda: Ifumene ileta evela kubaboneleli bemanyano ye-Renault-Nissan ngo-Epreli ka-2019 ukuze babonelele nge-1.157 yezigidi zeeseti zeebhetri ze-automotive hybrid kule minyaka isi-7 izayo. Kuqikelelwa ngokungqongqo ukuba isixa seodolo siya kudlula i-yuan yeebhiliyoni ezili-10. NgoJuni ka-2020, uNissan wabhengeza ukuba uza kusebenzisana neXinwangda ukuphuhlisa isizukulwana esilandelayo seebhetri zemoto kwiinkqubo zamandla ombane.

Eve Lithium. NgoJanuwari 19, i-Efe Lithium yazisa ukuqaliswa komgca wemveliso yebhetri ye-Jingmen cylindrical, ukwandisa umthamo wonyaka wemveliso ye-18650 yeebhetri ze-lithium ukusuka kwi-2.5GWh ukuya kwi-5GWh, kunye nemveliso yonyaka ye-430 yezigidi. Olu chungechunge luya kusetyenziselwa iibhayisekile zombane.

Iteknoloji yeFeineng. ITekhnoloji yeFeineng lishishini elikhokelayo kwibhetri ye-ternary ethambileyo yaseTshayina. Iseke intsebenziswano kunye ne-Geely, kunye nomthamo wexesha elizayo we-120GWh, apho ukwakhiwa kuya kuqalisa ngo-2021.
