Munguva pfupi yapfuura, chirevo cheCCTV che "kuchaja kweawa imwe chete uye kumira mumutsara kwemaawa mana" chamutsa nhaurirano dzakapisa. Hupenyu hwebhatiri uye nyaya dzekuchaja dzemotokari nyowani dzesimba dzave zvakare nyaya inopisa kumunhu wese. Parizvino, zvichienzaniswa neyechinyakare liquid lithium mabhatiri, solid-state lithium mabhatirinekuchengetedzeka kwepamusoro, kuwanda kwesimba rakakura, hupenyu hurefu hwebhatiri, uye nzvimbo dzekushandisa dzakafarainotariswa zvakanyanya neindasitiri mukati seyamangwana rekuvandudza kutungamira kwelithium mabhatiri. Makambani ari kukwikwidzawo pakuronga.
Kunyangwe iyo yakasimba-state lithium bhatiri isingakwanise kutengeswa munguva pfupi, iyo yekutsvagisa nekusimudzira maitiro eiyo solid-state lithium bhatiri tekinoroji nemakambani makuru yave kukurumidza uye nekukurumidza munguva pfupi yapfuura, uye kudiwa kwemusika kunogona kukurudzira kugadzirwa kwakawanda kweiyo solid- state lithium bhatiri pamberi pechirongwa.Ichi chinyorwa chichaongorora kusimukira kweiyo solid-state lithium bhatiri musika uye maitiro ekugadzira akasimba-state lithium mabhatiri, uye kukutora iwe kuti uongorore otomatiki musika mikana iripo.
Solid-state lithium mabhatiri ane zviri nani simba density uye kugadzikana kwekupisa kupfuura liquid lithium mabhatiri.
Mumakore achangopfuura, kuvandudzwa kunoramba kuripo munzvimbo yepasi pekushandisa kwaisa mberi kwepamusoro uye kwepamusoro zvinodiwa kuindasitiri yebhatiri yelithium, uye tekinoroji yebhatiri yelithium yakaramba ichivandudzwa, ichienda kune yakakwira chaiyo simba uye kuchengetedzeka.Kubva pamaonero enzira yekuvandudza yelithium bhatiri tekinoroji, simba remagetsi rinogona kuwanikwa ne lithium mabhatiri zvishoma nezvishoma rasvika painogumira, uye solid-state lithium mabhatiri ndiyo chete nzira yekuvandudza mabhatiri e lithium.
Zvinoenderana ne "Technical Roadmap yeKuchengetedza Magetsi uye New Energy Vehicles", iyo simba density tarisiro yemabhatiri emagetsi ndeye 400Wh/kg muna 2025 uye 500Wh/kg muna 2030.Kuti uwane chinangwa cha2030, iyo iripo yemvura lithium bhatiri tekinoroji nzira inogona kusakwanisa kutakura mutoro. Zvakaoma kutyora simba density sirin'i ye350Wh/kg, asi simba remagetsi e-soli-state lithium mabhatiri anogona kudarika 350Wh/kg.
Inotungamirwa nekudiwa kwemusika, nyika inoisawo kukosha kukuru mukuvandudzwa kwemabhatiri e-lithium akasimba.Mu "New Energy Vehicle Industry Development Plan (2021-2035)" (Draft for Comment) yakaburitswa muna Zvita 2019, inokurudzirwa kusimbisa kutsvagisa nekusimudzira uye indasitiri yemabhatiri e-lithium akasimba, uye kusimudza mabhatiri e-lithium akasimba. kusvika padanho renyika, sezvakaratidzwa muTable 1.
Tafura 1 Kuenzanisa kuongororwa kwemabhatiri emvura uye yakasimba-state mabhatiri
Kwete chete kumota nyowani dzemagetsi, iyo indasitiri yekuchengetedza simba ine yakakura application nzvimbo
Kupesvedzerwa nekusimudzirwa kwemitemo yenyika, kukurumidza kuvandudza kweiyo simba nyowani indasitiri yemotokari ichapa nzvimbo yakakura yekusimudzira yemabhatiri e-lithium yakasimba.Pamusoro pezvo, ese-akasimba-state mabhatiri e-lithium anozivikanwa zvakare seimwe yeichiri kubuda tekinoroji nzira inotarisirwa kupaza nepakati pebhodhoro remagetsi emagetsi ekuchengetedza tekinoroji uye kusangana nezvido zvebudiriro mune ramangwana.Panyaya yekuchengetedzwa kwemagetsi emagetsi, mabhatiri e lithium parizvino anoverengera makumi masere muzana emagetsi emagetsi ekuchengetedza simba.The cumulative yakaiswa simba re electrochemical energy kuchengetedza muna 2020 i3269.2MV, kuwedzera kwe91% muna 2019. Zvakasanganiswa negwara renyika rekusimudzira simba, kudiwa kwekuchengeterwa kwemagetsi emagetsi mudivi remushandisi-, renewable energy grid-yakabatana zvivakwa uye mimwe minda inotarisirwa kuunza kukura nekukurumidza, sezvakaratidzwa muMufananidzo 1.
Kutengesa uye kukura kwemotokari nyowani dzesimba kubva munaNdira kusvika Gunyana 2021 Cumulative yakaiswa simba uye chiyero chekukura kwemapurojekiti ekuchengetedza simba remakemikari muChina kubva 2014 kusvika 2020.
Mufananidzo 1 Kutengesa uye kukura kwemotokari itsva dzesimba; cumulative yakaiswa simba uye chiyero chekukura kwemakemikari ekuchengetedza simba mapurojekiti muChina
Mabhizinesi anomhanyisa maitiro ekutsvagisa nekusimudzira, uye China kazhinji inofarira maoxyde system
Mumakore achangopfuura, musika mukuru, makambani ebhatiri uye makambani makuru emotokari ese atanga kuwedzera tsvakiridzo yekumisikidza yakasimba-state lithium mabhatiri, achitarisira kutonga makwikwi mune inotevera-chizvarwa simba bhatiri tekinoroji.Nekudaro, zvinoenderana nekufambira mberi kwazvino, zvinotora makore mashanu kusvika gumi kuti mabhatiri e-solid-state lithium ave akakura musainzi uye tekinoroji yekugadzira isati yagadzirwa.Makambani emotokari epasi rose akadai seToyota, Volkswagen, BMW, Honda, Nissan, Hyundai, nezvimwewo vari kuwedzera mari yavo yeR&D musimba-state lithium bhatiri tekinoroji; maererano nemakambani ebhatiri, CATL, LG Chem, Panasonic, Samsung SDI, BYD, nezvimwewo vari kuramba vachigadzira.
All-solid-state lithium mabhatiri anogona kupatsanurwa muzvikamu zvitatu zvinoenderana nemagetsi emagetsi: polymer solid-state lithium mabhatiri, sulfide solid-state lithium mabhatiri, uye oxide solid-state lithium mabhatiri.Iyo polymer solid-state lithium bhatiri ine kuchengetedzwa kwakanaka, iyo sulfide solid-state lithium bhatiri iri nyore kugadzira, uye iyo oxide solid-state lithium bhatiri ine yakanyanya conductivity.Parizvino, makambani eEurope neAmerica anofarira oxide uye polymer masisitimu; Makambani eJapan neKorea anotungamirwa neToyota neSamsung anonyanya kufarira masisitimu esulfide; China ine vaongorori mune ese matatu masisitimu, uye kazhinji inofarira masisitimu eoxide, sezvakaratidzwa mumufananidzo 2.
Mufananidzo 2 Mamiriro ekugadzirwa kweakasimba-state lithium mabhatiri emakambani ebhatiri uye makambani makuru emotokari
Kubva pamaonero ekutsvagisa nekufambira mberi kwebudiriro, Toyota inozivikanwa semumwe wevatambi vane simba kwazvo mumunda weiyo solid-state lithium mabhatiri munyika dzekunze. Toyota yakatanga kurudzira zviitiko zvakakosha muna 2008 payakabatana neIlika, yakasimba-state lithium bhatiri kutanga-up.Muna Chikumi 2020, mota dzemagetsi dzeToyota dzakashongedzerwa neese-solid-state lithium mabhatiri akatoita bvunzo dzekutyaira munzira yekuyedza.Ikozvino yasvika padanho rekuwana data yekutyaira motokari.MunaGunyana 2021, Toyota yakazivisa kuti ichaisa madhora zviuru gumi nezvitatu nemazana mashanu emadhora panosvika 2030 kugadzira mabhatiri echizvarwa chinotevera uye cheni dzekugovera bhatiri, kusanganisira yakasimba-state lithium mabhatiri.Mumba, Guoxuan Hi-Tech, Qingtao New Energy, uye Ganfeng Lithium Indasitiri yakagadzira mitsara midiki yekugadzira mitsara yesemi-solid lithium mabhatiri muna 2019.MunaGunyana 2021, Jiangsu Qingtao 368Wh/kg solid-state lithium bhatiri yakapasa chitupa chenyika chakasimba chekuongorora, sezvakaratidzwa muTable 2.
Tafura 2 Solid-state bhatiri zvirongwa zvekugadzira emabhizinesi makuru
Kuongororwa kwemaitiro eoxide-based solid-state lithium mabhatiri, kupisa kudzvanya maitiro inzira nyowani
Iyo yakaoma yekugadzira tekinoroji uye yakakwira mutengo wekugadzira yakagara ichiganhurira kugadzirwa kwemaindasitiri eiyo solid-state lithium mabhatiri. Kuchinja kweiyo solid-state lithium mabhatiri anonyanya kuratidzwa mukugadzirwa kwesero, uye maelectrode awo nemaelectrolyte ane zvinodikanwa zvepamusoro zvenzvimbo yekugadzira, sezvakaratidzwa muTebhu 3.
Tafura 3 Kuongorora kweoxyde-based solid-state lithium mabhatiri
1. Nhanganyaya yezvakajairwa midziyo - lamination hot press
Model function sumo: Iyo lamination inopisa yekutsikirira inonyanya kushandiswa mune synthesis process chikamu chese-yakasimba lithium bhatiri maseru. Kuenzaniswa neyakajairwa lithium bhatiri, iyo inopisa yekutsikirira ndiyo nyowani link, uye yemvura jekiseni link haipo. zvinodiwa zvepamusoro.
Otomatiki chigadzirwa kumisikidza:
• Chiteshi chega chega chinoda kushandisa 3 ~ 4 axis servo motors, ayo anoshandiswa palamination lamination uye gluing zvichiteerana;
