Mabhatiri eLithiumZvave chikamu chakakosha chehupenyu hwedu hwezuva nezuva, zvichipa simba kune zvese kubva kumafoni nemalaptop kusvika kumotokari dzemagetsi uye masisitimu ekuchengetera simba rinodzokororwa. Nhoroondo yemabhatiri e-lithium rwendo runonakidza rwakatora makumi emakore akati wandei, rwakaratidzwa nekufambira mberi kukuru muhunyanzvi uye hunyanzvi. Kubva pakutanga kwavo kusvika pari zvino semhinduro dzekuchengetedza simba, mabhatiri e-lithium akachinja nzira yatinoshandisa nekuchengetedza magetsi.
Kugadzirwa kwemabhatiri e lithium
Nyaya yemabhatiri e lithiamuinotangira kuma1970, apo vaongorori vakatanga kuongorora kugona kwe lithium sechinhu chakakosha mumabhatiri anogona kuchajwazve. Panguva iyi ndipo masayendisiti akawana hunhu hwakasiyana hwe lithium, kusanganisira simba rayo rakawanda uye hunhu hwayo hwakareruka, zvichiita kuti ive yakakodzera midziyo yemagetsi inotakurika. Kuwanikwa uku kwakaisa hwaro hwekuvandudzwa kwemabhatiri e lithium-ion, ayo acharamba achitonga musika wemagetsi evatengi kwemakore anotevera.
Muna 1979, John Goodenough, nyanzvi yemakemikari yeOxford University, nechikwata chake, vakagadzira bhatiri rekutanga re lithium-ion rinochajwazve. Basa iri rekutanga rakaisa hwaro hwekutengeserana kwemabhatiri e lithium-ion, ayo ari kukurumidza kuwana mukurumbira nekuda kwekushanda kwawo kwepamusoro uye hupenyu hwebasa hwakareba kana tichienzanisa nemabhatiri echinyakare e lead-acid ne nickel-cadmium.
Mumakore ekuma1980 nema1990, tsvakurudzo yakakura nekuvandudza zvinhu zvakatarisa pakuvandudza mashandiro uye kuchengetedzeka kwemabhatiri e lithium. Chimwe chezvinetso zvikuru ndechekuwana electrolyte yakagadzikana inogona kutsungirira huwandu hwakawanda hwesimba re lithium pasina kukanganisa kuchengetedzeka. Izvi zvakaita kuti pave nekugadzirwa kwemhando dzakasiyana dze electrolyte uye masisitimu ekutarisira mabhatiri anovandudza zvakanyanya kuvimbika uye kuchengetedzeka kwemabhatiri e lithium-ion.
Kubudirira kwemabhatiri e lithium
Mumakore ekuma1980 nema1990, tsvakurudzo yakakura nekuvandudza zvinhu zvakatarisa pakuvandudza mashandiro uye kuchengetedzeka kwemabhatiri e lithium. Chimwe chezvinetso zvikuru ndechekuwana electrolyte yakagadzikana inogona kutsungirira huwandu hwakawanda hwesimba re lithium pasina kukanganisa kuchengetedzeka. Izvi zvakaita kuti pave nekugadzirwa kwemhando dzakasiyana dze electrolyte uye masisitimu ekutarisira mabhatiri anovandudza zvakanyanya kuvimbika uye kuchengetedzeka kwemabhatiri e lithium-ion.
Mavambo ekutanga e2000 akaratidza shanduko huru kumabhatiri e-lithium, nekufambira mberi mu nanotechnology nesainzi yezvinhu zvakakurudzira kugadzirwa kwemabhatiri e-lithium iron phosphate (LiFePO4) ne lithium polymer. Makemikari matsva aya emabhatiri anopa simba rakawanda, kugona kuchaja nekukurumidza uye kuchengetedza kwakawedzerwa, zvichiwedzera kushandiswa kwemabhatiri e-lithium muzvikamu zvemotokari, zvemuchadenga uye zvesimba rinogona kuvandudzwa.
Remangwana remabhatiri e lithiamu
Kushandiswa kwakapararira kwemotokari dzemagetsi (EVs) uye kudiwa kuri kukura kwemhinduro dzekuchengetedza simba kwakatungamira kukura kwekushanda kwepamusoro.mabhatiri e lithiamuMumakore achangopfuura, kufambira mberi kukuru muhunyanzvi hwemabhatiri senge solid electrolytes uye silicon anodes zvakawedzera kuvandudza huwandu hwesimba uye hupenyu hwema cycle emabhatiri e lithium, zvichiita kuti ave sarudzo inoshanda yekuchengetedza simba rakakura uye kugadzikana kwegrid.
Nhoroondo yemabhatiri e-lithium inoratidza kutsvaga hunyanzvi husina magumo uye simba rekuchinja kwetekinoroji. Nhasi, mabhatiri e-lithium idombo guru rekuchinja kwesimba rakachena, zvichiita kuti mota dzemagetsi dzishandiswe zvakanyanya uye simba rinowanikwazve risanganisirwe. Sezvo nyika ichitsvaga kuderedza kuvimba kwayo nemafuta epasi uye kurwisa shanduko yemamiriro ekunze, mabhatiri e-lithium achaita basa guru mukuumba remangwana rinogara kwenguva refu uye risina kabhoni yakawanda.
Mhedziso
Muchidimbu, nhoroondo yekuvandudzwa kwemabhatiri e lithiamurwendo runoshamisa rwekutsvaga kwesainzi, hunyanzvi hwetekinoroji, uye shanduko yemaindasitiri. Kubva pamazuva avo ekutanga sezvinhu zvinoshamisa zverabhoritari kusvika pari zvino semhinduro dzekuchengetedza simba dziripo, mabhatiri e-lithium abudirira zvikuru mukupa simba munyika yemazuva ano. Sezvatinoramba tichivhura mukana wemabhatiri e-lithium, tichaunza nguva itsva yekuchengetedza simba kwakachena, kwakavimbika uye kunoenderera mberi kuchaumba ramangwana repasi redu.
Kana muine mibvunzo kana kuti muchida kuziva zvakawanda, musazeza kupindurataura nesu.
