Suav tuam txhab EV hais tias nws yog engineered lub ntiaj teb thawj semi-khoom- xeev EV roj teeb nrog loj 620-mais ntau yam

Cov txheej txheem tsim kev sim tuaj yeem muaj ib hnub xa ib lub tsheb nrog 1,000-ntxiv mais ntau, cov kws tshawb fawb hais.

Cov thev naus laus zis tshiab muaj lub zog ntom ntom ntawm ntau dua 500 watt-teev ib kilogram - 30% siab dua li cov roj teeb lithium -ion roj teeb.

Cov kws tshawb fawb hauv Suav teb tau sim ib qho tom ntej no -tiam khoom- lub xeev roj teeb uas muaj peev xwm thawb lub tsheb hluav taws xob kom deb dhau qhov kev txwv tam sim no: muaj peev xwm ntau dua 620 mais (1,000 mais) ib tus nqi, thiab tseem nyob deb ntawm cov qauv yav tom ntej.

Cov kws tshawb fawb ntawm Nankai University, Tianjin, tau tsim lub siab -zog, muaj zog- lub xeev cov roj teeb uas lawv tau hais tias twb tau teeb tsa hauv lub tsheb tiag tiag thiab tau sim mus ntev - tsav tsheb deb, cov neeg sawv cev hauv tsev hais hauv nqe lus.

The technology packs an energy density exceeding 500 watt-hours per kilogram - an increase of 30% over current leading lithium-ion batteries at 300 Wh/kg - according to the statement. Siab dua - roj teeb ceev txhais tau tias muaj zog ntau dua (thiab ntau yam) rau qhov hnyav dua, thiab hauv ib qho me me.

Thaum cov ntsiab lus hais txog lub tsheb tshwj xeeb lub roj teeb tau sim nyob rau hauv tsis tshua muaj, cov ntawv ceeb toom tom ntej qhia tias nws yog tus qauv tsim los ntawm Tuam Tshoj FAW Group lub tuam txhab tsim roj teeb, Tuam Tshoj Automotive New Energy Battery (CANEB).

Cov khoom siv - lub xeev cov roj teeb txhim kho ntawm lawv cov kev sib raug zoo hauv ntau txoj hauv kev, suav nrog kev nyab xeeb, cov kws tshawb fawb tau hais. Cov kua electrolytes hauv lithium - ion roj teeb yog cov nplaim taws, thaum cov khoom siv hluav taws xob tsis yog -flammable thiab tsis tshua muaj kev puas tsuaj loj. Cov khoom electrolytes kuj tseem tuaj yeem muab lub neej ntev dua vim qhov txo qis hauv kev loj hlob ntawm dendrite - hlau spikes uas ua rau luv luv Circuit Court - thiab degradation los ntawm cov kua chemistry.

Thaum tseem nyob rau theem kev txhim kho, qee cov khoom siv roj teeb - lub xeev cov ntaub ntawv tseem tuaj yeem tso cai kom them sai dua, vim tias cov ion conductivity ntau dua ntawm cov khoom electrolyte.

Lub roj teeb tshiab tso siab rau lithium- nplua nuj manganese cathode thiab cov khoom sib xyaw ua ke- kua electrolyte system. Cov qauv tsim hybrid sib xyaw ua ke qhov zoo ntawm cov khoom siv - xeev architecture nrog "super-wetting" cov electrolyte, uas yog npaj los txhim kho ionic conductivity thiab kev nyab xeeb.

Super wetting yog hais txog cov electrolyte kis thoob plaws thiab nkag mus rau qhov chaw thiab qhov hws ntawm cov ntaub ntawv roj teeb, ua kom muaj kev sib cuag ntawm nws tus kheej thiab cov khoom siv nquag kom ions tuaj yeem txav tau zoo dua. Lub roj teeb tseem nta lithium anode thev naus laus zis uas tau tsim los txo cov nqi tsim khoom los ntawm kev ua kom yooj yim rau kev tsim khoom.

Lub roj teeb tam sim no muaj tag nrho lub peev xwm ntawm 142 kilowatt-teev (lub pob tag nrho lub zog khaws cia) thiab lub zog ntom ntom ntawm 288 Wh / kg ntawm qhov system theem ntau dua li 500 Wh / kg qhov ntom ntom coj los ntawm kev sib cais - suav nrog cov tshuab cua txias, xaim, kev txhawb nqa thiab kev ruaj ntseg. Qhov kev poob qis no yog qhov qub thiab ua raws li cov roj teeb EV tau tshaj tawm txog kev lag luam -wide.

Cov neeg tsim khoom hais tias kev rov ua dua tuaj yeem tshaj 340 Wh / kg ntawm qib pob thiab 200 kWh tag nrho muaj peev xwm, thawb kev tsav tsheb dhau 1,000 mais (1,600 km). Kev tawm tsam xav tias yuav pib qee lub sijhawm xyoo no, raws li cov lus hais.

Qhov 1,000-mais ntau yuav yog qhov nce ntxiv ntawm qhov ntau ntawm txawm tias cov EVs siab tshaj plaws tam sim no muaj. Raws li tsab ntawv ceeb toom los ntawm EV.com, qhov nruab nrab ntawm EVs tsim nyob rau hauv 2024 yog 283 mais (455 km), nrog rau cov qauv saum toj kawg nkaus ntawm 512 mais (825 km). Qhov ntau yam saum toj kawg nkaus yog muaj los ntawm Lucid Air thiab tseem tsis tau tshaj tawm hauv 2026.

Cov txiaj ntsig ntawm cov roj teeb hauv lub xeev - cov txiaj ntsig tau los ntawm lub tsev kawm ntawv qib siab - kev lag luam kev sib koom tes thiab tseem tsis tau raug txheeb xyuas tus kheej hauv cov phooj ywg - tshuaj xyuas kev tshawb fawb. Uas tau hais tias, txoj haujlwm tseem ceeb npaum li cas cov roj teeb hauv lub xeev tau nrawm nrawm los ntawm kev sim sim mus rau qhov tseeb- kev sim hauv ntiaj teb, thiab tuaj yeem hloov kho qhov ntau, kev nyab xeeb thiab kev ua haujlwm ntawm EVs.
