Mabhatiri eSekondari, akadai semabhatiri e-lithium ion, anoda kuiswa patsva kana simba rakachengetwa rashandiswa.Mukuda kuderedza kutsamira kwedu pamafuta ezvicherwa, masayendisiti anga achitsvaga nzira dzakasimba dzekuchaja mabhatiri echipiri.Nguva pfupi yadarika, Amar Kumar (mudzidzi akapedza kudzidza paTN Narayanan's lab muTIFR Hyderabad) nevamwe vake vakaunganidza compact lithium ion bhatiri ine photosensitive zvinhu zvinogona kuchajwa zvakanangana nesimba rezuva.
Kuedza kwekutanga kufambisa simba rezuva rechaji mabhatiri kwakashandiswa kushandiswa kwemasero ephotovoltaic nemabhatiri sezvikamu zvakasiyana.Simba rezuva rinoshandurwa nemasero ephotovoltaic kuita simba remagetsi iro rinozochengetwa sesimba remakemikari mumabhatiri.Simba rinochengetwa mumabhatiri aya rinobva rashandiswa kusimbisa midziyo yemagetsi.Iyi relay yesimba kubva kune chimwe chikamu kuenda kune imwe, semuenzaniso, kubva kune photovoltaic cell kusvika kubhatiri, inotungamirira kune imwe kurasikirwa kwesimba.Kuti udzivise kurasikirwa kwesimba, pakanga paine shanduko yakanangana nekuongorora mashandisirwo emifananidzo mukati mebhatiri pacharo.Pakave nekufambira mberi kwakanyanya mukubatanidza mafotosensitive components mukati mebhatiri zvichikonzera kuumbwa kwemamwe mabhatiri ezuva.
Kunyangwe akavandudzwa mukugadzira, mabhatiri ezuva aripo achiri ane zvimwe zvinokanganisa.Zvishoma zvezvakaipa izvi zvine chekuita nemhando dzakasiyana dzemabhatiri ezuva zvinosanganisira: kudzikira kugona kushandisa simba rezuva rakakwana, kushandisa organic electrolyte iyo inogona kukanganisa photosensitive organic component mukati mebhatiri, uye kuumbwa kwezvigadzirwa zvepadivi izvo zvinokanganisa kushanda kwakasimba kwebhatiri mukati. kwenguva refu.
Muchidzidzo ichi, Amar Kumar akafunga kuongorora zvinhu zvitsva zvefotosensitive izvo zvinogona zvakare kubatanidza lithium uye kuvaka bhatiri resolar iro rinove rakavuza-chiratidzo uye rinoshanda nemazvo mumamiriro akapoteredza.Mabhatiri eSolar ane maelectrode maviri anowanzo sanganisira dhayi ine photosensitive mune imwe yemagetsi yakasanganiswa nechikamu chinodzikamisa icho chinobatsira kutyaira kuyerera kwemaerekitironi kuburikidza nebhatiri.Elekitirodhi inova musanganiswa wenyama wezvinhu zviviri ine painogumira pakushandiswa kwakakwana kwenzvimbo ye electrode.Kudzivirira izvi, vaongorori kubva kuboka reTN Narayanan vakagadzira heterostructure ye photosensitive MoS2 (molybdenum disulphide) uye MoOx (molybdenum oxide) kuti ishande semagetsi ega ega.Kuve heterostructure umo iyo MoS2 neMoOx zvakasanganiswa pamwechete nekemikari vapor deposition tekinoroji, iyi electrode inobvumira imwe nzvimbo yepamusoro kutora simba rezuva.Kana mwaranzi yemwenje ichirova electrode, iyo photosensitive MoS2 inogadzira maerekitironi uye panguva imwe chete ichigadzira nzvimbo dzinodaidzwa kuti maburi.MoOx inochengeta maerekitironi nemaburi zvakaparadzana, uye inotamisa maerekitironi kudunhu rebhatiri.
Iri bhatiri rezuva, iro rakanyatso kuunganidzwa kubva pakutanga, rakaonekwa richishanda zvakanaka kana rakafumurwa nechiedza chezuva.Kuumbwa kweheterostructure electrode inoshandiswa mubhatiri iri yakadzidzwa zvakanyanya nekutapurirana ma electron microscope zvakare.Vanyori vechidzidzo parizvino vari kushanda kuti vafukure mashandisirwo ayo MoS2 neMoOx zvinoshanda pamwe chete ne lithium anode zvichikonzera chizvarwa chezvino.Nepo bhatiri rezuva iri richiwana kupindirana kwepamusoro kwephotosensitive zvinhu nechiedza, richiri kuzadzisa chizvarwa cheakanyanya mazinga emazuva ano kuti anyatso kuzadzazve lithium ion bhatiri.Nechinangwa ichi mupfungwa, TN Narayanan's lab iri kuongorora kuti akadai heterostructure electrode anogona sei kugadzira nzira yekugadzirisa matambudziko emazuva ano mabhatiri ezuva.
