Ibi ni ihinduka rya kabiri rikomeye mu mateka ya peteroli ya coke

"Icyerekezo" cy'Ubu: Kwimikwa k'Umwami mu gihe cya Lithium Battery

Ibi ni byo bihindura isura ya kabiri mu mateka ya peteroli.

Inkomoko

Mu myaka ya 1990, Sony Corporation yagurishije bateri za lithium-ion neza. Kubona ibikoresho bya electrode mbi bikwiye byabaye ingenzi cyane. Abahanga mu bya siyansi bagerageje ibikoresho bitandukanye bya karuboni.

Kuki ari ngombwa gukoresha peteroli?

Nyuma yo gutunganya graphitization, peteroli coke ifite imiterere ya grafiti ifite ibice binini bitanga "hoteri" nziza yo gushyiramo no gukuramo iyoni za lithium. Ifite ibyiza byinshi nko kuba ifite ubushobozi bwo hejuru, igihe kirekire cyo gukora uruziga, hamwe n'urusobe rw'amashanyarazi ruhamye.

Kuva muri Laboratwari kugera ku nganda mpuzamahanga

Icyiciro cya mbere (1990 - 2000)

Ibigo by’Abayapani (nka Hitachi Chemical) byafashe iya mbere mu ikoranabuhanga, bishyiraho urwego rw’ibanze rwa electrodes za graphite negative based petroleum coke.

Kwaguka (imyaka ya 2000 - 2010)

Kubera ko telefoni zigendanwa na mudasobwa zigendanwa zagendaga zikundwa cyane, icyifuzo cyariyongereye cyane. Ibigo by’ubucuruzi byo muri Koreya n’Ubushinwa byakomeje gukora, bituma ubushobozi bwo gukora ibikoresho bya elegitoroniki ku isi bwazamuka vuba. Ubushake bwa neled coke nziza bwariyongereye cyane.

Irushanwa rikomeye (2010 – Ubu)

Umuraba w’ibinyabiziga bikoresha amashanyarazi ku isi wariyongereye cyane. Bateri z’amashanyarazi zashyizeho ibisabwa byinshi ku mikorere, igiciro, no ku buryo ibikoresho bya electrode mbi bigumana. Ibi byateye:

• Irushanwa ry'ikoranabuhanga: Irushanwa n'imikoranire hagati ya grafiti y'ubukorano (ikozwe muri needle coke), grafiti karemano, na electrodes za silikoni-karuboni.
• Gushakisha ibikoresho: Irushanwa mpuzamahanga ry’ibikoresho byiza bya “needle coke” ryariyongereye. Igiciro cyabyo n’uko ibicuruzwa bihagaze byabaye kimwe mu bintu by’ingenzi bigira ingaruka ku kiguzi cya bateri.

Incamake: Amasomo yo mu mateka

Amateka ya koke ya peteroli ya graphised ni inkuru isanzwe y’inganda ivuga ku “udushya dushingiye ku bibazo n’agaciro gasubiwemo.”

Byatangiye ari "ikibazo" mu gutunganya peteroli (gukuraho imyanda).

Binyuze mu "gutera imbaraga" kw'intambara (gusaba amatanura y'amashanyarazi) no "kugaburira" inganda z'ibanze (inganda za aluminiyumu), yarangije kuvugurura kwayo kwa mbere.

Mu gihe cy’ “igitutu” cyo kurengera ibidukikije n’ “impinduramatwara” mu bijyanye n’ingufu, yafashe amahirwe y’amateka maze amaherezo ihabwa ikamba ry’umwami mu gihe cy’ikoranabuhanga n’impinduramatwara y’ibinyabiziga bikoresha amashanyarazi.
