Ingxoxo: Kutheni ungayisebenzisi i-lithium iron phosphate?

Ngaba iimoto zombane zikaTesla zikhuselekile ukuba zisetyenziswe? Kutheni ungasebenzisi iibhetri ze-lithium iron phosphate? Ezi mpendulo zilandelayo zivela kubasebenzi bebhetri ye-lithium.

Njengenjineli esebenza kwiziko lophando, ekugqibeleni ndafumana ithuba lokuthetha amagama ambalwa malunga nentsimi yam.

Okokuqala, ukuze kulungiswe le ngcamango, ibhetri ye-lithium sisishunqulelo sento esihlala siyibiza ngokuba yibhetri ye-lithium. Into oyibiza ngokuba yi-ferroelectricity luhlobo lwebhetri ye-lithium. Isebenzisa i-lithium iron phosphate njengedatha ye-electrode efanelekileyo. Luhlobo lwebhetri ye-lithium.

Ngoku masiqale ngoguqulelo olulula lokutsalwa komphezulu:

I-Tesla isebenzisa i-Panasonic, kunye ne-NCA njenge-electrode efanelekileyo, kwaye icwangcisa inkqubo yokulawula ibhetri epheleleyo yokuqinisekisa nokuphucula ukusebenza kakuhle kunye nokukhuseleka kokusebenza kwebhetri. Ngokuphathelele ukuba ikhuselekile ngokuqinisekileyo, le nto ayinakuphendulwa. Ukuba ufuna ukuthetha malunga nokutsha okuzenzekelayo, ndifuna ukuthetha ukuba iimoto zepetroli ziya kuvutha ngokukhawuleza ehlotyeni.

Kwizithuthi zombane ezisulungekileyo, yintoni esiyixhalabele kakhulu? Oku akukho kude nexhala, kuba ubuninzi bamandla ezinokugcinwa iibhetri buphantsi kakhulu. Kule mihla, ubuninzi bamandla ebhetri yemoto budla ngokuba yi-100 ukuya kwi-150 Wh/kg, kwaye ubuninzi bamandla epetroli bumalunga ne-10,000. wh/kg. Ngoko ke nokuba uphethe inqwaba yeebhetri njengofudo, awukwazi ukumelana nayo. Masihleke indlela iimoto zombane eziphelelwa ngayo amandla ngexesha lokutshaja kwemihla ngemihla.

Obona buthathaka bukhulu betekhnoloji yebhetri yangoku kukuxinana kwamandla asezantsi, okushiyeke kakhulu emva koMthetho kaMoore. Sukuthetha nge-lithium engenanto, nokuba ubuninzi bamandla abo abukho phezulu ngokwaneleyo, bakude nokuba luncedo…

Esona sizathu siphambili sokungasebenzisi iibhetri ze-lithium iron phosphate, ndingathanda ukuthi, ngumthamo ophantsi kunye namandla aphantsi (i-lithium iron phosphate ingaphantsi kancinane kwe-3, i-voltage ephantsi, i-3.4V, ngoko ke amandla aphantsi). Kusetyenziso olusebenzayo, iipakethi zebhetri yemoto zonke zidityanisiwe kuthotho kunye nokuhambelana, kwaye uthotho lwendlela yoqhagamshelo iyafuneka ukunyusa amandla ombane. Ngeli xesha, ukuhambelana kwamandla ombane kunye nomthamo phakathi kweebhetri ezahlukeneyo kubaluleke kakhulu, kwaye akunangqiqo ukusho ukuba umthamo uphantsi.

Ukuze uthelekise amanqaku amaninzi afanelekileyo edatha, kufuneka sazise le grafu, ezizezi iindlela ezintlanu ezibalulekileyo zokusebenza:

Amandla, ubomi, iindleko, ukhuseleko kunye namandla.

Idatha yokuthelekisa i-NMC / NCA idatha kathathu / i-NCA, i-LCO lithium cobaltate, i-LFP lithium ye-iron phosphate kunye ne-LMO lithium manganenate. I-NCA kunye ne-NCM zizalamane ezisondeleyo, ngoko zidibene apha.

Kumfanekiso sinokubona:

Amanani oMdibaniso

Amandla awona mancinci (ngelishwa, amandla aphantsi yingxaki, i-voltage ephantsi yingxaki ye-3.4V, njenge-4.7V lithium NMC spinel). Indawo ilinganiselwe, ngoko ke musa ukufaka intlawulo kunye nokukhupha iijika apha.

Amandla akakho phantsi konke konke (uvavanyo lwe-pilot ye-lithium iron phosphate 5C inokufikelela kwi-130mAh / g drop (PHOSTECH nayo …) I-carbon package + nano data multiplier isenamandla kakhulu!

Ubomi kunye nokhuseleko ubomi yeyona ilungileyo, nto leyo ibalulekileyo kuba kucingelwa ukuba polyanion PO43-

Ukongeza, i-oksijini idibanisa ngcono kunye ne-electrolyte, okubangela ukuphindaphinda okuphantsi. Ngokungafaniyo nedatha ye-ternary, kulula ukubonisa amaqamza oksijini kunye nezinye izinto. Ngokubhekiselele kwixesha lokuphila, ngokuqhelekileyo kuthathwa njengokwazi ukwenza imijikelo engama-4000.

Iindleko ziphezulu, kwaye ixabiso le-lithium iron phosphate lilungile. Iindleko zesibini kuphela kwi-LMO lithium manganate (le nto, ukutsha komoya, umthombo we-manganese ungabizi), kwaye okwesibini kukhuphiswano. Izinto ze-lithium iron phosphate, i-lithium phosphorus incinci, kodwa ezinye iindleko, ukwenza umgubo, unyango lobushushu kunye nomoya wobuvila, iimfuno zenkqubo ezahlukeneyo, okubangelwa iindleko zedatha (malunga ne-10 w / t e-China) azikho phantsi njenge-LMO (6 ~ 7 w/t), kodwa i-NMC (13 w/t) isephantsi kune-LCO (ibiza kakhulu).

Isizathu: I-Cobalt ibiza kakhulu kune-nickel, kwaye i-nickel ibiza kakhulu kune-ferromanganese. Ziziphi izinto ezisetyenziswayo kunye neendleko ezisetyenzisiweyo.

Emva koko thelekisa kwaye uhlalutye idatha yeNCM/NCA elandelayo

Amandla yiyona nzuzo enkulu (iimoto zombane zifuna nje ukuya phambili, oku kubaluleke kakhulu). Ukongeza, ngophuhliso lwedatha ye-nickel ephezulu ye-NCM, ukuxinana kwamandla kwedatha kunokuphuculwa ngakumbi.

Amandla akukho ngxaki (enyanisweni, kwizithuthi zombane ezicocekileyo, amandla abaluleke ngaphezu kweempawu zamandla, kodwa kwiinqwelo ezixubileyo ezifana neToyota Prius, iimpawu zamandla zibaluleke kakhulu, kodwa isiseko kukuba amandla awabi).
