Nissan Motor neNissan ARC vakazivisa musi waKurume 13, 2014 kuti vakagadzira nzira yekuongorora iyo inogona kucherechedza nekuyera kufamba kwemaerekitironi mune yakanaka electrode zvinhu zvemabhatiri e lithiamu-ion panguva yekuchaja nekubuditsa. Uchishandisa nzira iyi, “inoita kuti kugadziriswe kwemhando yepamusoro-lithium-ion mabhatiri kugoneke, nokudaro zvichibatsira kuwedzera huwandu hwemota dzakachena dzemagetsi (EV)”

Kugadzira iyo lithiamu-ion bhatiri ine yakakwira huremu uye hupenyu hwakareba, zvinodikanwa kuchengetedza yakawanda lithiamu sezvinobvira mune iyo electrode inoshanda zvinhu, uye dhizaini zvinhu izvo zvinogona kuburitsa yakawanda yakawanda maerekitironi. Nechikonzero ichi, zvakakosha kuti ubate kufamba kwemaerekitironi mubhatiri, uye maitiro ekare ekuongorora haakwanise kucherechedza kufamba kwemaerekitironi. Naizvozvo, hazviite kuti uwane huwandu hwenyaya iri mu electrode inoshanda zvinhu (manganese (Mn), cobalt (Co), nickel (Ni), oxygen (O), nezvimwewo) inogona kuburitsa maerekitironi.

Iyo nzira yekuongorora yakagadziriswa nguva ino yagadzirisa dambudziko rakamira kwenguva refu-kuwanikwa kweakabva azvino panguva yekuchaja uye kuburitsa uye nekuibata yakawanda “yepasi rose” (Nissan Motor). Nekuda kweizvozvo, zvinokwanisika kuti ubate nemazvo izvo zvinoitika zviri kuitika mukati mebhatiri, kunyanya kufamba kwechinhu chinoshanda chiri mune yakanaka electrode zvinhu. Mhedzisiro iyi nguva yakabatanidzwa neNissan ARC, iyo University yeTokyo, Kyoto University, uye Osaka Prefectural University.

Zvakare akashandisa iyo “Earth Simulator”

Maitiro ekuongorora akagadzirwa panguva ino anoshandisa zvese zviri zviviri “X-ray yekumwa yekuratidzira” achishandisa iyo “L yekumwa magumo” uye “yekutanga-misimboti nzira yekuverenga” uchishandisa supercomputer “Earth Simulator”. Kunyangwe vamwe vanhu vakashandisa X-ray yekumwa masekrosikopu kuita lithiamu-ion bhatiri kuongorora pamberi, iko kushandiswa kwe “K kunonoka kupera” ndiko kwakanyanya. Maerekitironi akarongedzwa muK shell layer padyo padyo nenucleus yakasungwa muatomu, saka maerekitironi haatore chikamu chaicho mukuchaja nekuburitsa.

Iyo yekuongorora nzira panguva ino inoshandisa X yekumwa masekrosekopu uchishandisa iyo L yekumedza magumo kunyatsocherechedza kuyerera kwemaelectroniki anotora chikamu mune bhatiri kuita. Uye zvakare, nekubatanidza neyekutanga-misimboti nzira yekuverenga uchishandisa iyo yepasi simulator, huwandu hwesimbi yemagetsi kufamba iyo yaigona kungogadziriswa kare isati yawanikwa nekukwirira kwakanyanya.

Iyo tekinoroji ichaita kukanganisa kukuru kune Rudzi rwebhatiri simba rekuchengetedza masisitimu

Nissan ARC inoshandisa iyi nzira yekuongorora kuongorora lithiamu-yakawandisa cathode zvinhu. Izvo zvakawanikwa kuti (1) mune yepamusoro-inogona mamiriro, maerekitironi ari eoksijeni anobatsira kune yekuchaja reaction; (2) painoburitsa, maerekitironi ari emanganese anobatsira pakuita zvinoitika.
