"Chinhu Chinoshamisa" Chemazuva Ano: Kugadzwa kwaMambo Munguva yeLithium Battery

Izvi zvinoratidza shanduko yechipiri inoyevedza munhoroondo yepetroleum coke.

Kwakatangira

Mumakore ekuma1990, Sony Corporation yakabudirira kutengesa mabhatiri e lithium-ion. Kuwana chinhu chakakodzera che electrode chakava chinhu chakakosha. Masayendisiti akaedza zvinhu zvakasiyana-siyana zvekabhoni.

Sei Petroleum Coke?

Mushure mekugadzirisa graphitization, petroleum coke ine chimiro chegraphite chakaiswa muzvikamu zvinopa "hotera" yakakodzera yekuisa nekubvisa lithium ions. Iine mabhenefiti akazara akadai sehukuru hwakasiyana, hupenyu hwenguva refu, uye platform yakasimba yemagetsi.

Kubva muLab kusvika kuIndasitiri yePasirose

Danho rekutanga (1990 - 2000)

Makambani ekuJapan (akadai seHitachi Chemical) akatungamira muhunyanzvi, achisimbisa chinzvimbo chikuru chemaelectrode ane graphite negative graphite akavakirwa papetroleum coke.

Kuwedzera (2000s - 2010s)

Nekukurumbira kwakapararira kwemafoni nemalaptop, kudiwa kwacho kwakawedzera. Makambani ekuKorea neChina akabudirira, zvikaita kuti pave nekukura kukuru kwekugadzira zvinhu zvisina simba pasi rose. Kudiwa kweneeled coke yemhando yepamusoro kwakawedzera zvakanyanya.

Makwikwi Akakomba (2010s - Parizvino)

Mafungu emotokari dzemagetsi pasi rose akapinda zvakanyanya. Mabhatiri emagetsi akaisa zvinodiwa zvakanyanya pakushanda, mutengo, uye kugara kwenguva refu kwezvinhu zvemagetsi zvisina kunaka. Izvi zvakakonzera:

• Makwikwi eTekinoroji: Makwikwi nekubatanidzwa kwegraphite yekugadzira (yakagadzirwa ne needle coke), graphite yechisikigo, uye electrodes dzisina silicon-carbon.
• Kukwikwidzana Kwezvinhu Zvinotengeswa: Makwikwi epasi rose ekushandisa zvinhu zvemhando yepamusoro zve needle coke akawedzera. Mutengo wayo nekugadzikana kwezvigadzirwa zvakava chimwe chezvinhu zvikuru zvinokanganisa mitengo yemabhatiri.

Pfupiso: Zvidzidzo kubva muNhoroondo

Nhoroondo ye graphitized petroleum coke inyaya yeindasitiri inowanzo shandiswa ye "kuvandudza zvinhu zvitsva zvinokonzereswa nematambudziko uye kukosha kwakagadziriswazve kwezvinodiwa."

Zvakatanga se "dambudziko" mukuchenurwa kwemafuta (kuraswa kwemarara).

Kuburikidza ne "catalyst" yehondo (kudiwa kwezvitofu zvemagetsi) uye "kudya" kwemaindasitiri ekutanga (indasitiri yearuminiyamu), yakapedza kuvandudza kwayo kwekutanga.

Pasi pe "dzvinyiriro" yekuchengetedzwa kwezvakatipoteredza uye "chimurenga" mune simba, yakashandisa mukana wenhoroondo uye pakupedzisira yakagadzwa samambo munguva yedhijitari uye chimurenga chemotokari dzemagetsi.
