Hurukuro: Sei usingaite lithium iron phosphate?

Mota dzemagetsi dzeTesla dzakachengeteka kushandisa here? Wadii kushandisa lithium iron phosphate mabhatiri? Mhinduro dzinotevera dzinobva kune lithium battery practitioners.

Seinjiniya anoshanda mune imwe nzvimbo yekutsvagisa, ndakazowana mukana wekutaura mazwi mashoma nezvemunda wangu.

Chekutanga pane zvese, kuitira kugadzirisa pfungwa iyi, lithium bhatiri ndiyo chidimbu chezvatinowanzo kudaidza kuti lithium bhatiri. Chaunodaidza kuti ferroelectricity imhando yelithium bhatiri. Inoshandisa lithium iron phosphate seyakanaka electrode data. Iyo imhando ye lithium bhatiri.

Zvino ngatitange neinyore vhezheni yekubvisa pamusoro:

Tesla inoshandisa Panasonic, ine NCA seyakanaka electrode, uye inoronga yakazara bhatiri manejimendi system kuti ive nechokwadi uye nekuvandudza kushanda uye kuchengetedzeka kwekushanda kwebhatiri. Kana zviri izvo zvakachengeteka, izvi hazvigone kupindurwa. Kana iwe uchida kutaura nezve kupisa kwega, ndinodawo kutaura kuti mota dzepeturu dzinongobatidzawo muzhizha.

Kune mota dzemagetsi dzakachena, chii chatinonyanya kunetsekana nacho? Izvi hazvisi kure nekushushikana, nekuti simba remagetsi rinogona kuchengeta mabhatiri rakaderera. Mazuva ano, kuwanda kwesimba remabhatiri emotokari kunowanzo 100 kusvika 150 Wh/kg, uye simba remagetsi peturu rinenge zviuru gumi. wh /kg. Saka nyangwe ukatakura murwi wemabhatiri sekamba, haugone kuzvibata. Ngatisekei kuti mota dzemagetsi dzinopera sei simba panguva yekuchaja zuva nezuva.

Kunyanya kushaya simba kweiyo bhatiri tekinoroji isimba rayo rakaderera, iro rinosara kumashure kweMutemo waMoore. Usataure nezve lithium isina chinhu, kunyangwe simba ravo resimba risina kukwirira zvakakwana, vari kure nekubatsira…

Chikonzero chikuru chekusashandisa lithium iron phosphate mabhatiri, ndinoda kutaura, ishoma simba uye simba rakaderera (lithium iron phosphate ishoma kudarika 3, yakaderera voltage, 3.4V, saka yakaderera simba). Mumashandisirwo anoshanda, emota bhatiri mapaketi ese akasanganiswa munhevedzano uye akafanana, uye yakatevedzana yekubatanidza nzira inodiwa kuti uwedzere voltage. Panguva ino, kuenderana kwesero voltage uye kugona pakati pemabhatiri akasiyana kunova kwakakosha, uye hazvisi kuchenjera kutaura kuti huwandu hwakaderera.

Kuti tienzanise akati wandei akanaka data mapoinzi, isu tinofanirwa kusuma iyi girafu, inova mashanu akakosha maitiro ekuita:

Simba, hupenyu, mutengo, kuchengeteka uye simba.

Iyo data yekuenzanisa ndeyeNMC/NCA katatu data/NCA, LCO lithium cobaltate, LFP lithium iron phosphate uye LMO lithium manganate. NCA neNCM ihama dzepedyo saka vakaungana pano.

Kubva pamufananidzo tinogona kuona:

Alliance statistics

Simba ndiro diki (zvinosuruvarisa, simba shoma idambudziko, low voltage idambudziko re 3.4V, yakadai se4.7V lithium NMC spinel). Space ishoma, saka usaise charge and discharge curves pano.

Simba harina kuderera zvachose (pilot test ye lithium iron phosphate 5C inogona kusvika 130mAh / g kudonha (PHOSTECH inogonawo …) Iyo carbon package + nano data multiplier ichiri yakasimba kwazvo!

Hupenyu nekuchengetedzwa kwehupenyu ndizvo zvakanakisa, izvo zvakakosha nekuti zvinofungidzirwa kuti polyanion PO43-

Mukuwedzera, okisijeni inobatanidza zviri nani ne electrolyte, zvichiita kuti iite yakaderera reactivity. Kusiyana nedatha yeternary, zviri nyore kuratidza mabhubhu okisijeni uye zvimwe zviitiko. Panyaya yehurefu hwehupenyu, inowanzoonekwa sekukwanisa kuita 4000 cycles.

Mutengo wakakwira, uye mutengo welithium iron phosphate wakanaka. Mutengo ndeyechipiri chete kune LMO lithium manganenate (chinhu ichi, kupisa kwemhepo, manganese sosi yakachipa), uye yechipiri inonyanya kukwikwidza. Lithium iron phosphate zvinhu, lithium phosphorus ishoma, asi mamwe madhiri, kugadzira hupfu, kupisa kupisa uye simbe mhepo, akasiyana maitiro zvinodiwa, zvichikonzera mutengo wedata (anenge 10 w / t muChina) hauna kuderera seLMO (6 ~ 7 w/t), asi NMC (13 w/t) ichiri yakachipa kupfuura LCO (inodhura).

Chikonzero: Cobalt inodhura kupfuura nickel, uye nickel inodhura kupfuura ferromanganese. Ndezvipi zvinhu zvinoshandiswa uye ndezvipi mari inoshandiswa.

Wobva waenzanisa uye ongorora inotevera NCM/NCA data

Simba ndiro rinobatsira zvikuru (motokari dzemagetsi dzinongoda kuenda mberi, ichi ndicho chinonyanya kukosha). Uye zvakare, nekuvandudzwa kweiyo yakakwira nickel NCM data, iyo simba density yedata inogona kuvandudzwa.

Simba harisi dambudziko (chaizvoizvo, kumotokari dzemagetsi dzakachena, simba rinonyanya kukosha kupfuura maitiro emagetsi, asi kumotokari dzakasanganiswa seToyota Prius, maitiro emagetsi anonyanya kukosha, asi chirevo ndechekuti simba harina kuipa).
