Penn: Tine ultra-fast way yekuchaja LiFePO4 masero: +2 400 km / h. Degradation? Mileage 3,2 miriyoni km!
Zviri mukati
Masayendisiti kubva kuPennsylvania State University akawana nzira yekuchaja mabhatiri e-lithium iron phosphate cell (LFP, LiFePO)4) Kutenda kune dhizaini yakakodzera, vanokwanisa kuvhara chinhambwe chinosvika mazana mana emakiromita mumaminitsi gumi (+ 400 km / h), iyo inoenderana nekuchaja huwandu hunosvika 10 C.
LFP maseru semukana wemotokari dzemagetsi dzakachipa uye dzinoshanda

- LFP maseru semukana wemotokari dzemagetsi dzakachipa uye dzinoshanda
- Nissan Leaf II sePorsche: yakanakisa kukwirisa, yakanyanya kukurumidza kuchaja
Takanyora kakawanda nezve mabhenefiti emasero eLFP: akachipa kupfuura NCA/NCM - uye anovimbisa zvakanaka kana zvasvika pakumwe kudzikiswa kwemitengo - akachengeteka, anoderedza zvishoma, uye anobvumira kutenderera kuzere pasina kukanganisa simba. kudzikisira. Kukanganisa kwavo isimba rakaderera uye kugona kumhanyisa kuchaja. Zvinoita sekuti zvakawanda zvakaitika nguva pfupi yadarika mune ese ekutanga (link iri pazasi) uye yechipiri (zvimwe zvechinyorwa).
> Guoxuan: Tasvika 0,212 kWh / kg mumasero edu eLFP, tinoenda mberi. Aya ndiwo mawebhusaiti eNCA / NCM!
Vatsvagiri vePennsylvania vakawana nzira kuwedzera kwesimba rekuchaja bhatiri rinobva pamasero eLFP... Zvakanaka, vakaputira maseru mune yakatetepa nickel foil yakabatana kune imwe yemagetsi ebhatiri. Kana kuchaja kunotanga, magetsi anoyerera nemavari. Iyo foil inopisa maseru (mukati mebhatiri) kusvika 60 degrees Celsius. uye mushure meizvozvo ndipo panotanga nzira yekuzadza simba.
Sezvo kupisa kusingabvi mukati mesero, asi mhedzisiro yekuwedzera heater, hapana dambudziko rinoratidzika nekukura kwe lithium dendrite.
Vatsvakurudzi vanoti nemasero anopisa vanozokwanisa kuzadza Kufamba-famba kwemakiromita mazana mana mumaminitsi gumi (+400 10 km / h)... Ivo havagone kuzvirumbidza nezve chaiyo yekuchaja simba kukosha, asi uchifunga kuti ikozvino inodiwa bhatiri huwandu hunofanirwa kuenderana nehupamhi hwe400-500 makiromita, kuchaja simba rinofanira kuva 4,8-6 C. Kana ichiburitsa - ichiri nemaseru anopisa - inovimbisa kukwanisa kugadzira 300kW yesimba kubva ku40kWh (7,5 ° C, kunobva) bhatiri.
Kuchaja kwesimba repamusoro kunofanirwa kuve kwakachengeteka zvachose kune akatsanangurwa maseru. Vesainzi vanovimbisa kusvika 3,2 mamiriyoni emakiromita, kureva, nepamusoro-soro (400-500 km) hupenyu hwesevhisi 6-400 zvizere zvekushandisa.
Nissan Leaf II sePorsche: yakanakisa kukwirisa, yakanyanya kukurumidza kuchaja
Kuti tinzwisise izvo zvese zviri pamusoro apa zvinorehwa, ngatizvimisei kune yekutanga mota pamucheto. Fungidzira Nissan Leafa II ine bhatiri riri pamusoro... Iine [yakazara] simba re40 kWh, bhatiri richakwanisa kuendesa kusvika ku300 kW (408 hp) yesimba, iyo, kunyange nekurasikirwa, inopa anenge 250 kW (340 hp) pamavhiri.
Mota yakadaro dai yaingokwanisa kuchengetedza kufamba chete, yaitoda kuita kwakafanana nePorsche Boxster uye ichabvumira kuzadzazve simba rekupa kusvika ku240 kW. Uye bhatiri rinopisa paunenge uchityaira zvingave zvakanakira, kwete kukanganisa, nekuti hazvizodi kudziyiswa kuti zvinyatsoshanda.
