Musi waMbudzi 19, 2023, njanji yenyika yakatanga kuedza kushanda kwemagetsi emagetsi e-lithium-ion mabhatiri mu "matunhu maviri neguta rimwe" reSichuan, Guizhou neChongqing, inova chiitiko chakakosha mundima yekufambisa yenyika yangu. Danho rekutanga iri, rakatorwa nemakambani anotungamira akadai seCATL neBYD Fudi Battery, rinoratidza nguva yakaoma mukuvandudzwa kwekufambisa kwenjanji munyika yangu. Pakutanga, kutakura njanji yemagetsi emagetsi lithium-ion mabhatiri akange asati avakwa. Uku kuyedza kuita "zero breakthrough" uye kunovhura zviri pamutemo modhi nyowani yekufambisa njanji.
Kuunzwa kwechitima chekutakura mabhatiri e-lithium-ion mabhatiri hakusi kungofambira mberi kwezvinhu, asiwo danho rekuvandudza mashandiro uye mutengo-kubudirira kwekutakura kwebhatiri. Mumamiriro ezvinhu emakwikwi epasi rose, kugona kutakura mabhatiri aya nenjanji kwakakosha sezvo ichizadzisa nzira dziripo dzekutakura dzakadai senjanji-gungwa uye njanji. Iyi nzira yekufambisa yakawanda inotarisirwa kusimudzira zvakanyanya kukwikwidza kunze kwenyika kwemabhatiri e-lithium-ion, ayo ari kuwedzera kuonekwa sedombo rekona re "vatatu vatsva" - motokari dzemagetsi, kuchengetedza simba rekugadzirisa uye teknolojia yebhatiri yepamusoro.
Lithium mabhatiri anoshandisa lithium simbi kana lithium alloys semidziyo ye electrode uye isiri-aqueous electrolyte mhinduro se electrolytes, uye yave yakasarudzika simba rekuchengetedza mhinduro pasi rese. Kubudirira kwayo kunogona kuteverwa kumashure kwekutanga kwezana ramakore rechi20, uye yakafambira mberi zvakanyanya mushure mekuonekwa kwekutanga kwemabhatiri e-lithium-ion muma1970s. Nhasi, mabhatiri e lithium anonyanya kukamurwa kuita mapoka maviri: lithium simbi mabhatiri uye lithium-ion mabhatiri. Iwo ekupedzisira haana simbi lithium uye anochajwazve, uye anozivikanwa nekuda kweakanakisa maitiro ekuita.
Chimwe chezvakanakira mabheti eti lithium isimba rawo rakawanda, rinosvika katanhatu kusvika kanomwe iro remabhatiri echinyakare lead-asidhi. Ichi chimiro chinovaita kunyanya kukodzera maapplication anoda kureruka uye anotakurika simba mhinduro, senge mota dzemagetsi uye inotakurika midziyo yemagetsi. Mukuwedzera, mabhatiri e-lithium ane hupenyu hurefu hwebasa, kazhinji anopfuura makore matanhatu, uye yakakwirira yakatemerwa voltage, ine imwe sero inoshanda voltage ye3.7V kana 3.2V. Simba rayo repamusoro rekubata simba rinobvumira kukurumidza kukurumidza, zvichiita kuti ive sarudzo yakanaka kune yakakwirira-yakasimba maapplication.
Mabhatiri eLithium ane mwero wakaderera wekuzviburitsa, kazhinji isingasviki 1% pamwedzi, izvo zvinowedzera kuwedzera kukwezva kwavo. Ichi chimiro chinovimbisa kuti simba rinochengetwa kwenguva yakareba, richivaita sarudzo yakavimbika yevatengi uye maindasitiri ekushandisa. Sezvo nyika iri kuwedzera kutendeukira kune inogadziriswa simba mhinduro, zvakanakira mabhatiri e lithium anovaita mutambi akakosha mukushanduka kuenda kune remangwana rakasvibira.
MuChina, kushandiswa kwesimba nyowani tekinoroji kunowedzera kupfuura chikamu chemotokari. Muyedzo wakabudirira welithium-ion bhatiri njanji yekutakura inosimbisa kuzvipira kweChina kubatanidza mhinduro dzesimba rinogoneka mumhando dzese dzekufambisa. Iyi nhanho haingonatsiridza mashandiro ebhatiri, asi zvakare inoenderana neChina chinangwa chakakura chekudzikisa kuburitsa kabhoni uye kusimudzira budiriro inoenderera.
Sezvo nharaunda yepasi rose ichishanda kugadzirisa matambudziko ekushanduka kwemamiriro ekunze uye kuparara kwezvakatipoteredza, kutora mabhatiri e-lithium uye kuvaka masisitimu ekufambisa anobudirira kuti agadzirise aya magadzirirwo emagetsi ekuchengetedza idanho rakakosha kuenda kune nyika yakasvibira. Kudyidzana pakati penjanji yenyika uye inotungamira kugadzira mabhatiri inomiririra mweya mutsva unofambisa shanduko yeChina kune simba risingaperi.
Mukupedzisa, kuyedza kushanda kwemotokari lithium-ion mabhatiri muChina njanji inomiririra kufambira mberi kukuru musimba renyika. Nekusimudzira zvakanakira mabhatiri e-lithium uye kusimudzira zvinhu zvekufambisa, China inotarisirwa kusimbisa chinzvimbo chayo mumusika wepasi rose wesimba ichibatsira kune ramangwana rakagadzikana. Sezvo nyika inofamba ichienda kune yakasvibira magetsi mhinduro, kubatanidzwa kwemabhatiri e-lithium munzvimbo dzakasiyana siyana, kusanganisira njanji, kuchaita basa rakakosha mukuumba yakachena uye inoshanda zvakanyanya ecosystem yesimba.
