Tattaunawa: Me yasa ba’a lithium iron phosphate ba?

Shin motocin lantarki na Tesla suna da aminci don amfani? Me yasa ba za a yi amfani da batir phosphate na lithium baƙin ƙarfe ba? Amsoshi masu zuwa sun fito daga masu aikin batirin lithium.

A matsayina na injiniya mai aiki a cibiyar bincike, a ƙarshe na sami damar faɗi wasu kalmomi game da fannina.

Da farko, don gyara wannan ra’ayi, baturin lithium shine taƙaitaccen abin da muke kira baturin lithium. Abin da kuke kira ferroelectricity haƙiƙa wani nau’in baturi ne na lithium. Yana amfani da lithium iron phosphate a matsayin tabbataccen bayanan lantarki. Wani irin batirin lithium ne.

Yanzu bari mu fara da sassauƙan sigar abstraction na saman:

Tesla yana amfani da Panasonic, tare da NCA a matsayin ingantacciyar wutar lantarki, kuma yana tsara cikakken tsarin sarrafa baturi don tabbatarwa da inganta ingantaccen aiki da amincin aikin baturi. Dangane da ko yana da lafiya, ba za a iya amsa wannan ba. Idan kuna son yin magana game da konewa ba tare da bata lokaci ba, Ina kuma so in faɗi cewa motocin mai za su iya kunna wuta ba tare da bata lokaci ba a lokacin rani.

Ga motocin lantarki masu tsafta, menene muka fi damuwa da shi? Wannan bai yi nisa da damuwa ba, saboda ƙarfin ƙarfin da batura za su iya adanawa ya yi ƙasa sosai. A zamanin yau, yawan kuzarin batir mota yawanci 100 zuwa 150 Wh/kg, kuma yawan kuzarin mai yana kusan 10,000. ku /kg. Don haka ko da kuna ɗaukar tarin batura kamar kunkuru, ba za ku iya sarrafa shi ba. Mu yi dariya kan yadda motocin lantarki ke ƙarewa a lokacin cajin yau da kullun.

Babban rauni na fasahar baturi na yanzu shine ƙarancin ƙarfin ƙarfinsa, wanda yayi nisa a bayan Dokar Moore. Kada ku yi magana game da komai na lithium, ko da yawan kuzarin su bai isa ba, sun yi nisa da amfani…

Babban dalilin rashin amfani da batir phosphate na lithium baƙin ƙarfe, Ina so in ce, ƙananan ƙarfin aiki da ƙarancin makamashi (lithium iron phosphate dan kadan kasa da 3, ƙananan ƙarfin lantarki, 3.4V, don haka ƙananan makamashi). A aikace aikace, fakitin baturi na mota duk an haɗa su a jere da layi ɗaya, kuma ana buƙatar hanyar haɗin yanar gizo don ƙara ƙarfin lantarki. A wannan lokacin, daidaiton ƙarfin lantarki da iya aiki tsakanin batura daban-daban ya zama mahimmanci, kuma ba hankali ba ne a faɗi cewa ƙarfin yana da ƙasa.

Domin kwatanta mahimman bayanai da dama, dole ne mu gabatar da wannan jadawali, wato mahimman ma’auni na aiki guda biyar:

Ƙarfi, rayuwa, farashi, aminci da makamashi.

Bayanan kwatancen sune bayanan NMC/NCA sau uku/NCA, LCO lithium cobaltate, LFP lithium iron phosphate da LMO lithium manganate. NCA da NCM ’yan uwa ne na kut-da-kut, don haka an hada su a nan.

Daga cikin hoton muna iya gani:

Ƙididdiga na Alliance

Makamashi shine mafi ƙanƙanta (abin takaici, ƙarancin ƙarfi shine matsala, ƙarancin wutar lantarki shine matsalar 3.4V, kamar 4.7V lithium NMC spinel). Sarari yana da iyaka, don haka kar a sanya caji da fiddawa a nan.

Ƙarfin ba shi da ƙasa ko kaɗan (gwajin matukin jirgi na lithium iron phosphate 5C zai iya kaiwa 130mAh/g digo (PHOSTECH kuma…) Kunshin carbon + nano data multiplier har yanzu yana da ƙarfi sosai!

Rayuwa da amincin rayuwa sune mafi kyau, wanda yake da mahimmanci saboda ana hasashen cewa polyanion PO43-

Bugu da ƙari, oxygen yana haɗuwa da kyau tare da electrolyte, yana haifar da ƙananan reactivity. Ba kamar bayanan ternary ba, yana da sauƙi don nuna kumfa oxygen da sauran abubuwan mamaki. Dangane da tsawon rayuwa, ana ɗaukarsa gabaɗaya zai iya yin hawan keke 4000.

Kudin yana da yawa, kuma farashin lithium iron phosphate yana da kyau. Farashin shine na biyu kawai ga LMO lithium manganate (wannan abu, konewar iska, tushen manganese yana da arha), kuma na biyu mafi fa’ida. Lithium baƙin ƙarfe phosphate abu, lithium phosphorus ne in mun gwada da cheap, amma wasu halin kaka, yin foda, zafi magani da kuma m yanayi, daban-daban tsari bukatun, sakamakon data halin kaka (game da 10 w / t a kasar Sin) ba su da ƙasa kamar LMO (6 ~ 7 w/t), amma NMC (13 w/t) har yanzu yana da arha fiye da LCO (mafi tsada).

Dalili: Cobalt ya fi nickel tsada, kuma nickel ya fi ferromanganese tsada. Abin da kayan da ake amfani da kuma abin da kudin da ake amfani da.

Sannan kwatanta ku bincika bayanan NCM/NCA masu zuwa

Makamashi shine babbar fa’ida (motocin lantarki kawai suna son ci gaba, wannan shine mafi mahimmanci). Bugu da ƙari, tare da haɓaka manyan bayanai na nickel NCM, za a iya inganta yawan makamashi na bayanai.

Ƙarfin wutar lantarki ba shi da matsala (a gaskiya, ga motocin lantarki masu tsabta, makamashi yana da mahimmanci fiye da halayen wutar lantarki, amma ga motoci masu haɗaka kamar Toyota Prius, halayen wutar lantarki sun fi mahimmanci, amma jigon shine cewa wutar lantarki ba ta da kyau).
