I-Nissan Motor kunye ne-Nissan ARC babhengeza nge-13 ka-Matshi 2014 ukuba baphuhlise indlela yohlalutyo enokujonga ngokuthe ngqo kunye nokulinganisa ukuhamba kwe-elektroni kwizixhobo ezifanelekileyo ze-electrode zebhetri ye-lithium-ion ngexesha lokutshaja nokukhupha. Sebenzisa le ndlela, “kwenza ukuba kuphuculwe amandla eebhetri ze-lithium-ion ezinokubakho, oko kunceda ukwandisa uluhlu lwezithuthi zombane ezimsulwa (EV)”

Ukuphuhlisa ibhetri ye-lithium-ion enomthamo omkhulu kunye nobomi obude, kufuneka kugcinwe i-lithium eninzi kwizinto ze-electrode ezisebenzayo, kunye nezinto eziyilo ezinokuvelisa isixa esikhulu se-elektrononi. Ngesi sizathu, kubaluleke kakhulu ukubamba ukuhamba kwe-elektroni kwibhetri, kwaye iindlela zangaphambili zohlalutyo azinakukujonga ngokuthe ngqo ukuhamba kwe-elektroni. Ke ngoko, akunakwenzeka ukuba kuchongwe ngobungakanani ukuba yeyiphi into esebenzayo kwizinto ze-electrode (manganese (Mn), cobalt (Co), nickel (Ni), oxygen (O), njl. Njl.

Indlela yohlalutyo ephuhliswe ngeli xesha isombulule ingxaki ekudala ikho-ukufunyanwa kwemvelaphi yangoku ngexesha lokutshaja nokukhupha kunye nokubamba ubungakanani bayo “kwihlabathi lokuqala” (iNissan Motor). Ngenxa yoko, kunokwenzeka ukuba ubambe ngokuchanekileyo izinto ezenzeka ngaphakathi kwebhetri, ngakumbi ukuhamba kwezinto ezisebenzayo eziqulethwe kwizixhobo ezifanelekileyo ze-electrode. Iziphumo ngeli xesha zidityaniswe ngokudibeneyo yiNissan ARC, iYunivesithi yaseTokyo, iYunivesithi yaseKyoto, kunye ne-Osaka Prefectural University.

I-Tesla yokugcina ibhetri yamandla

Kwakhona wasebenzisa i “Earth Simulator”

Indlela yohlalutyo ephuhliswe ngeli xesha isebenzisa zombini “i-X-ray yokufunxwa kwesibonakude” isebenzisa i “L yokungenisa isiphelo” kunye “nendlela yokuqala yokubala imigaqo” kusetyenziswa i-supercomputer “Earth Simulator”. Nangona abanye abantu basebenzise i-X-ray absorption spectroscopy ukwenza uhlalutyo lwebhetri ye-lithium-ion ngaphambili, ukusetyenziswa kwe “K absorption end” yeyona nto iphambili. Ii-elektroni ezilungelelaniswe kuluhlu lweqokobhe le-K elikufutshane nenucleus zibotshelelwe kwiatom, ke ii-elektroni azithathi nxaxheba ngokuthe ngqo kwintlawulo kunye nokukhupha.

Indlela yohlalutyo ngeli xesha isebenzisa i-X yokutsalwa kwe-spectroscopy isebenzisa isiphelo se-L sokujonga ukujonga ngokuthe ngqo ukuhamba kwee-elektronon ezithatha inxaxheba kwimpendulo yebhetri. Ukongeza, ngokudibanisa nemigaqo-nkqubo yokubala yokuqala usebenzisa isimulator somhlaba, isixa sentshukumo ye-electron enokuthi yenziwe kuphela ngaphambi kokufunyanwa ngokuchaneka okuphezulu.

Obo buchwephesha buza kwenza impembelelo enkulu kwiindidi zeenkqubo zokugcina amandla ebhetri

INissan ARC isebenzisa le ndlela yohlalutyo ukuhlalutya izinto ze-lithium-excess cathode materials. Kwafunyaniswa ukuba (1) kwisikhundla esinamandla amakhulu, ii-elektroni zeoksijini ziluncedo ekuphenduleni; (2) xa ukhupha, ii-elektroni zeemanganizi ziluncedo ekuphenduleni.
