Anthu aku China apanga ma capacitor omwe amatha kusintha lingaliro la magalimoto amagetsi

Pafupifupi osadziwika Kumadzulo, kampani yaku China Toomen New Energy ku Shenzhen yatha kupanga ukadaulo wopanga ma capacitor amagetsi, omwe amatha kukhala kusagwirizana pakati pa ma supercapacitors ndi mabatire a lithiamu-ion. Chitukukocho chinakhala chapadera mosayembekezereka ngakhale kwa akatswiri apamwamba a ku Ulaya ndi asayansi.

Ku Europe, mnzake wa Toomen New Energy adakhala woyamba ku Belgian Kurt.Energy. Mtsogoleri woyambitsa, Eric Verhulst, adapeza malo ang'onoang'ono a Toomen New Energy pachiwonetsero cha Hannover Messe ku Germany kumbuyo mu 2018, pomwe amawona ukadaulo wolonjeza wa batri pamafakitale amagetsi amagetsi. Ma capacitor amphamvu a Toomen omwe adayesedwa adaposa maloto onse owopsa a injiniya. Pa nthawiyo, makhalidwe awo anali aakulu nthawi 20 kuposa a Maxwell mankhwala ofanana. Panali chinachake chodabwitsidwa nacho!

Mwamadongosolo, Toomen power capacitor ndi chinthu chosungira magetsi osagwiritsa ntchito mankhwala, monga zimachitika mu supercapacitor. Electrode imodzi ya "activated carbon" imapangidwa ndi graphene, ndipo ina "yochokera pa lifiyamu pawiri, koma poyerekeza ndi mabatire a lithiamu-ion palibe lithiamu yogwira."

Akamapangidwa, magwero osungiramo mphamvu zotere ndi okwera mtengo kuposa a lithiamu-ion akale, koma potengera dola pa kilowatt pa cycle (charge), ndiotsika mtengo. Komanso, chifukwa cha mphamvu zambiri zotulutsa mphamvu, ma capacitors amagetsi angagwiritsidwe ntchito muzomera zamagetsi zosakanizidwa zamagalimoto ngati njira yosungiramo, yomwe ingapulumutse mafuta, ndipo idzayimbidwa mwachangu - mumphindi zochepa.

Toomen power capacitors alibe electrolyte. M'malo mwake, zinthuzo zimakhala ndi zodzaza zina zotengera ndalama. Kapangidwe kameneka kamakhala koopsa kwa chilengedwe ngati chipolopolocho chikang’ambika ndipo sichikhoza kuyaka.

Toomen panopa amapanga mitundu iwiri ya capacitor mphamvu. Mmodzi wa iwo amayang'ana pa kachulukidwe wapamwamba kwambiri wa mphamvu zosungidwa, ndipo winayo amapereka mphamvu zambiri. Maselo a Toomen omwe ali ndi mphamvu zambiri pakali pano amapereka mphamvu zokhala pakati pa 200-260 Wh/kg, zokhala ndi mphamvu zoyambira 300-500 W/kg. Zinthu zamphamvu zotulutsa mphamvu zambiri zimayimiriridwa ndi zitsanzo zokhala ndi mphamvu zofikira 80–100 Wh/kg zokhala ndi mphamvu zofikira pafupifupi 1500 W/kg ndikumafika pachimake mpaka 5000 W/kg.

Poyerekeza, ma supercapacitor a Maxwell a DuraBlue amakono amapereka mphamvu zochepa kwambiri za 8–10 Wh/kg, koma mphamvu zamphamvu kwambiri zozungulira 12–000 W/kg. Kumbali ina, batire yabwino ya lithiamu-ion imapereka mphamvu yosungira mphamvu ya 14-000 Wh / kg, ndi mphamvu yamagetsi m'dera la 150-250 Wh / kg. Ndizosavuta kuwona kuti ma capacitor a Toomen amapereka mphamvu yayikulu kwambiri yosungiramo mphamvu pakuchulukira kwamphamvu kwa ma supercapacitors komanso kuchulukira kwamphamvu kwambiri pamalire a kachulukidwe kake kakusungirako mphamvu mumabatire a lithiamu-ion.

Kuphatikiza apo, ma capacitor amagetsi a Toomen amatha kugwira ntchito kutentha koyambira -50ºC mpaka 45ºC popanda chitetezo chotenthetsera kapena kuzirala. Kwa mabatire agalimoto, uwu ndi mwayi wofunikira, chifukwa sangafune chitetezo chilichonse chamafuta kapena kuwongolera zamagetsi, zomwe zikutanthauza kuti adzapulumutsa zina zambiri pamtengo ndi kulemera kwa gawo lamagetsi.
