Lokhu kuphawula isikhathi sesibili esikhazimulayo emlandweni we-petroleum coke

“I-Epic” Yanamuhla: Ukugcotshwa KweNkosi Enkathini Yebhethri Le-Lithium

Lokhu kuphawula isikhathi sesibili esimangalisayo emlandweni we-petroleum coke.

Umsuka

Ngawo-1990, i-Sony Corporation yaphumelela ekuthengiseni amabhethri e-lithium-ion. Ukuthola izinto ezifanele ze-electrode engalungile kwaba yinto ebalulekile. Ososayensi bazama izinto ezahlukene zekhabhoni.

Kungani i-Petroleum Coke?

Ngemva kokwelashwa kwe-graphitization, i-petroleum coke inesakhiwo se-graphite esinezingqimba esihlinzeka “ngehhotela” elifanele lokufakwa nokukhishwa kwama-ion e-lithium. Inezinzuzo eziphelele njengomthamo othize ophezulu, impilo yomjikelezo omude, kanye nepulatifomu ye-voltage ezinzile.

Kusukela Elabhorethri Kuya Embonini Yomhlaba Wonke

Isigaba Sokuqala (1990 - 2000)

Izinkampani zaseJapan (njengeHitachi Chemical) zahola kwezobuchwepheshe, zasungula isimo esijwayelekile sama-electrode angemuhle e-graphite asekelwe ku-petroleum coke.

Ukwanda (2000s - 2010s)

Ngenxa yokuthandwa kabanzi kwama-smartphone nama-laptop, isidingo sanda. Amabhizinisi aseKorea naseShayina afinyelela ezingeni elifanele, okwaholela ekwandeni okusheshayo kwamandla okukhiqiza izinto ze-electrode ezimbi emhlabeni jikelele. Isidingo se-needle coke esezingeni eliphezulu sakhula kakhulu.

Umncintiswano Oqinile (2010s – Okwamanje)

Igagasi lezimoto zikagesi zomhlaba wonke langena ngamandla. Amabhethri kagesi abeka izidingo eziphezulu kakhulu ekusebenzeni, izindleko, kanye nokungaguquguquki kwezinto ze-electrode ezingezinhle. Lokhu kwabangela:

• Ukuncintisana Kwezobuchwepheshe: Ukuncintisana kanye nokuhlanganiswa phakathi kwe-graphite yokwenziwa (eyenziwe nge-needle coke), i-graphite yemvelo, kanye nama-electrode angemuhle e-silicon-carbon.
• Ukuncintisana Kwezinketho Zokunikezela: Umncintiswano womhlaba wonke wezinsizakusebenza ze-needle coke ezisezingeni eliphezulu wanda. Intengo yayo kanye nokuqina kokunikezwa kwaba ngenye yezinto ezibalulekile ezithinta izindleko zebhethri.

Isifinyezo: Izifundo Ezivela Emlandweni

Umlando we-graphitized petroleum coke uyindaba evamile yezimboni "yokusungula izinto ezintsha okubangelwa izinkinga kanye nenani elibunjwe kabusha lesidingo."

Kwaqala “njengenkinga” ekuhlanzeni uwoyela (ukulahlwa kwemfucuza).

Ngokusebenzisa “isikhuthazi” sempi (isidingo sezitofu zikagesi) kanye “nokondliwa” kwezimboni eziyisisekelo (imboni ye-aluminium), yaqeda ukuthuthukiswa kwayo kokuqala.

Ngaphansi “kwengcindezi” yokuvikelwa kwemvelo kanye “noguquko” lwamandla, yathatha ithuba eliyingqophamlando futhi ekugcineni yabekwa njengenkosi enkathini yedijithali kanye noguquko lwezimoto zikagesi.
