Kukhalitsa: Chipangizochi chimagwiritsa ntchito kale ma cell a lithiamu-ion okhala ndi silicon anode. Zosankha? Tisalankhule
Purezidenti wa Sila Nano adalemba kuti ma cell a lithiamu-ion okhala ndi silicon anode angopita ku chipangizo choyamba. Iyi ndiye tracker yolimbitsa thupi ya Whoop 4.0, yomwe wopanga amati ili ndi batri yokhala ndi 17 peresenti yamphamvu kwambiri kuposa chipangizo choyambirira.
Ma silicon anodes ndi oyamba mu zida zazing'ono zapakhomo komanso mtsogolo, mwachitsanzo, ku Mercedes
Sila Nano sakufuna kuulula magawo a maselo atsopano (voltage kudutsa maelekitirodi, okwana mphamvu kachulukidwe, etc.). Komanso sichiwulula yemwe kwenikweni amapanga mabatire chifukwa Sila Nano amangopanga silicon powder anode ndipo maselo anapangidwa ndi munthu wina. Kotero ife timangokhala ndi 17 peresenti yomwe yatchulidwa ndipo zonena kuti mabatire atsopano amatanthauza masensa atsopano angagwiritsidwe ntchito ndi moyo wa batri womwewo pamene kuchepetsa mphamvu ya chipangizo ndi 1/3 (gwero, mwayi wolipira; gwero).
Masiku ano ma lithiamu-ion cell anode amagwiritsa ntchito mitundu yosiyanasiyana ya kaboni, nthawi zina ndikuwonjezera silicon. The silicon anode ali ndi ubwino kuti akhoza kugwira ndi kusunga kwa 10 nthawi zambiri lithiamu ayoni kuposa graphite anode. Mwangongole ndiye batire yogwiritsa ntchito silikoni imatha kuwirikiza ka 10 mphamvu yake.
Komabe, zenizeni si zabwino kwenikweni kwa ife. Kuthekera kwapamwamba kwa kapangidwe ka silicon kumatanthauza kuti 1) mu gawo loyambirira la ntchito ya selo, pamene wosanjikiza wosanjikiza umapangidwa, ma ion a lithiamu ambiri amakhala osasunthika kosatha. Ndipo izi ndi 2) ma ion a lithiamu amakankhira padera zida za silicon kwambiri (ziyenera kukhala kwinakwake), zomwe zimabweretsa kuwonongeka kwa anode. Zotsatira zake Lifiyamu yochulukirapo ikufunika kupanga selo la silicon anode (= mtengo wapamwamba) Oraz njira zowonjezera zokhazikika zomwe zimalepheretsa kutupa kwa kapangidwe kake.
Zikuoneka kuti Sila Nano anatha kuthetsa osachepera ena mwa mavuto ndi pa nthawi yomweyo kupanga limagwirira kupanga misa silicon anodes. Pazaka 10 zapitazi, ntchito yopanga yakwera kwambiri nthawi chikwi (kamodzi). Kuti maselo a lithiamu-ion omwe ali ndi silicon anode apite m'magalimoto, njira yamakono iyenera kufulumizitsidwa ndi gawo la 1 (gwero). Kampaniyo imaneneratu kuti m'zaka zikubwerazi za 000-100, mabatire a lithiamu-ion adzafika pamsika pa $ 5 pa ola la kilowatt, kuthandizira kulipira mwachangu komanso imapirira mikombero 10, zaka 000 zogwira ntchito.
Sila Nano ndi imodzi mwa makampani omwe akuthandiza Mercedes (Daimler) kukhazikitsa mafakitale ake a lithiamu-ion batire.
Izi zingakusangalatseni:
