Oku kubonisa inguqu yesibini ezukileyo kwimbali ye-petroleum coke

"I-Epic" Yanamhlanje: Ukumiselwa koKumkani kwiXesha lebhetri yeLithium

Oku kuphawula inqanaba lesibini elizukileyo kwimbali ye-petroleum coke.

Imvelaphi

Kwiminyaka yoo-1990, iSony Corporation yaphumelela ekuthengiseni iibhetri ze-lithium-ion. Ukufumana izinto ezifanelekileyo ze-electrode engalunganga kwaba yinto ebalulekileyo. Izazinzulu zenze uvavanyo ngezinto ezahlukeneyo zekhabhoni.

Kutheni iPetroleum Coke?

Emva konyango lwe-graphitization, i-petroleum coke inesakhiwo se-graphite esineengqimba esibonelela "ngehotele" efanelekileyo yokufaka kunye nokukhupha ii-ion ze-lithium. Inezibonelelo ezibanzi ezifana nomthamo ophezulu, ubomi bomjikelo omde, kunye neqonga le-voltage elizinzileyo.

Ukusuka kwiLabhoratri ukuya kwiShishini leHlabathi

Inqanaba lokuqala (1990s - 2000s)

Iinkampani zaseJapan (ezifana neHitachi Chemical) zikhokele kubuchwepheshe, ziseka imeko ephambili yee-electrodes ze-graphite negative graphite ezisekelwe kwi-petroleum coke.

Ulwandiso (ngeminyaka yoo-2000 ukuya kowama-2010)

Ngenxa yokuthandwa kakhulu kweefowuni eziphathwayo kunye neelaptop, imfuno yanda kakhulu. Amashishini aseKorea naseTshayina afikelela kwinqanaba elaneleyo, nto leyo eyakhokelela ekwandeni ngokukhawuleza kwamandla emveliso yezinto ze-electrode ezingezizo zehlabathi. Imfuno ye-needle coke ekumgangatho ophezulu yakhula ngokukhawuleza.

Ukhuphiswano Olukhulu (2010s – Okwangoku)

Izandi zezithuthi zombane zehlabathi zangena ngamandla. Iibhetri zamandla zabeka iimfuno eziphezulu kakhulu ekusebenzeni, kwiindleko, nasekuhambelaneni kwezinto ze-electrode ezimbi. Oku kwabangela:

• Ukhuphiswano lweTekhnoloji: Ukhuphiswano kunye nokuhlanganiswa phakathi kwegrafiti yokwenziwa (eyenziwe nge-needle coke), igrafiti yendalo, kunye nee-electrodes ezingezizo ze-silicon-carbon.
• Ukuxinana Kweempahla: Ukhuphiswano lwehlabathi ngezixhobo ze-needle coke ezikumgangatho ophezulu luye lwaqina. Ixabiso layo kunye nokuzinza kobonelelo kube yenye yezinto eziphambili ezichaphazela iindleko zebhetri.

Isishwankathelo: Izifundo ezivela kwiMbali

Imbali ye-graphitized petroleum coke yimbali eqhelekileyo yezoshishino "yobuchule obuqhutywa yingxaki kunye nexabiso elihlengahlengisiweyo leemfuno."

Kwaqala “njengengxaki” ekucocweni kweoyile (ukulahlwa kwenkunkuma).

Ngokusebenzisa "i-catalyst" yemfazwe (imfuno yezitofu zombane ze-arc) kunye "nokondla" kwamashishini asisiseko (ishishini le-aluminium), yagqiba uphuculo lwayo lokuqala.

Phantsi “koxinzelelo” lokukhuselwa kwendalo kunye “noguquko” kumandla, yathatha ithuba lembali yaza ekugqibeleni yathweswa isithsaba sokuba yikumkani kwixesha ledijithali kunye noguquko lwezithuthi zombane.
