Batteri ya kabiri, nka batiri ya lithium ion, igomba kongera kwishyurwa iyo ingufu zabitswe zimaze gukoreshwa.Mu rwego rwo kugabanya kwishingikiriza ku bicanwa by’ibinyabuzima, abahanga bagiye bashakisha uburyo burambye bwo kwishyuza bateri ya kabiri.Vuba aha, Amar Kumar (umunyeshuri urangije muri laboratoire ya TN Narayanan muri TIFR Hyderabad) na bagenzi be bakusanyije bateri ya lithium ion yuzuye hamwe nibikoresho bifotora bishobora kwishyurwa biturutse ku mirasire y'izuba.
Imbaraga zambere zo gukoresha ingufu zizuba kugirango zishiremo bateri yakoresheje gukoresha selile yifotora na bateri nkibintu bitandukanye.Imirasire y'izuba ihindurwa ningirabuzimafatizo zifotora mumashanyarazi zikabikwa nkingufu za chimique muri bateri.Ingufu zibitswe muri bateri noneho zikoreshwa mugukoresha ibikoresho bya elegitoroniki.Uku kwerekanwa kwingufu kuva mubice bimwe kugeza mubindi, kurugero, kuva selile yifotora kugeza kuri bateri, biganisha ku gutakaza ingufu.Kugirango wirinde gutakaza ingufu, habaye impinduka mugushakisha imikoreshereze yibikoresho bifotora imbere muri bateri ubwayo.Habayeho iterambere ryinshi muguhuza ibice byifotora muri bateri bigatuma habaho bateri nyinshi zizuba.
Nubwo byatejwe imbere mubishushanyo, bateri zuba zihari ziracyafite imbogamizi.Bimwe muribi bibi bifitanye isano nubwoko butandukanye bwa bateri yizuba harimo: kugabanuka kwubushobozi bwo gukoresha ingufu zizuba zihagije, gukoresha electrolyte kama ishobora kwangiza ibinyabuzima byamafoto yumubiri imbere muri bateri, no gukora ibicuruzwa byuruhande bibangamira imikorere ya bateri muri igihe kirekire.
Muri ubu bushakashatsi, Amar Kumar yahisemo gucukumbura ibikoresho bishya bifotora bishobora kandi gushiramo lithium no kubaka bateri yizuba idashobora kumeneka kandi ikora neza mubihe bidukikije.Imirasire y'izuba ifite electrode ebyiri mubusanzwe zirimo irangi ryifotora muri imwe muri electrode ivanze kumubiri hamwe nibintu bituza bifasha gutwara imigozi ya electron binyuze muri bateri.Electrode nuruvange rwumubiri rwibikoresho bibiri rufite aho rugarukira kumikoreshereze myiza yubuso bwa electrode.Kugira ngo wirinde ibi, abashakashatsi bo mu itsinda rya TN Narayanan bakoze imiterere itandukanye ya MoS2 (molybdenum disulphide) na MoOx (molybdenum oxyde) kugirango bakore nka electrode imwe.Kuba imiterere itandukanye aho MoS2 na MoOx byahujwe hamwe nubuhanga bwo kubika imyuka ya chimique, iyi electrode ituma ubuso bunini bushobora kwinjiza ingufu zizuba.Iyo imirasire yumucyo ikubise electrode, MoS2 yifotora itanga electron kandi icyarimwe ikora imyanya yitwa umwobo.MoOx ituma electron hamwe nu mwobo bitandukanya, kandi ikohereza electron kumuzunguruko wa batiri.
Iyi batiri yizuba, yakusanyirijwe hamwe kuva kera, wasangaga ikora neza mugihe ihuye numucyo wizuba.Ibigize electrode ya heterostructure ikoreshwa muri iyi bateri yizwe cyane hamwe na microscope yohereza.Abanditsi b'ubushakashatsi barimo gukora ubu kugirango bagabanye uburyo MoS2 na MoOx zikorana na lithium anode bigatuma habaho ibisekuruza.Mugihe iyi bateri yizuba igera kumikoranire ihanitse yibikoresho bifotora hamwe numucyo, ntabwo iragera kubisekuru byurwego rwiza rwumuyaga kugirango yongere yishyure batiyeri ya lithium.Hamwe niyi ntego, laboratoire ya TN Narayanan irimo gushakisha uburyo electrode nkiyi ya heterostructure ishobora gutanga inzira yo gukemura ibibazo bya bateri yizuba ya none.
