Nangona kukho iindaba zeebhetri zombuso oqinileyo mva nje, kusekho ubunzima obuninzi okufuneka busonjululwe kwiibhetri zombuso oqinileyo. Kusekho indlela ende yokuya kwimveliso yayo yorhwebo kunye nokusetyenziswa kwizithuthi zamandla amatsha. 48VAGV lithium ibhetri.jpg

Iibhetri zamandla zangoku ziseziibhetri ze-ternary kunye neebhetri ze-lithium iron phosphate. Kwixesha elidlulileyo lexesha, iibhetri ze-lithium iron phosphate ziye zanda ngamandla, kwaye izithuthi zabagibeli zamandla ezitsha ziye zatshintsha ukusuka kwiibhetri ze-ternary ukuya kwiibhetri ze-lithium iron phosphate.

Eli nqaku lijonga umahluko phakathi kweebhetri ze-ternary kunye neebhetri ze-lithium iron phosphate ukusuka kwiimbono ezintlanu: ukhuseleko, ubuninzi bamandla, ukukhutshwa kobushushu obuphantsi, ukusebenza kakuhle kokutshaja, kunye nobomi bomjikelezo.

1. Khu seleko

Ibhetri yeblade yibhetri ye-lithium iron phosphate. Ibhetri ye-blade ibonakalise ukuba inokuphumelela uvavanyo olunzima lwe-acupuncture, ngelixa ibhetri ye-ternary ayikwazi. Ke ngoko, ibhetri ye-lithium iron phosphate yibhetri ekhuselekileyo kunebhetri ye-ternary.

Ukongeza, ukuzinza kwe-thermal ye-lithium iron phosphate cathode impahla ngokwayo ingcono kakhulu kune-ternary lithium. Inozinzo oluphezulu kakhulu phakathi kwama-500 degrees celsius. Ukubaleka kwe-Thermal kwenzeka xa kungaphezu kwama-800 degrees Celsius. Ukongeza, nokuba kwenzeka ukubaleka kwe-thermal, Ukukhutshwa kobushushu kwebhetri ye-lithium iron phosphate nako kucotha kakhulu, kwaye akuyi kukhulula ioksijini xa ibola, ukunciphisa umngcipheko womlilo.

Ngokwahlukileyo koko, iibhetri ze-lithium ze-ternary ziqala ukunyibilika malunga ne-300 degrees Celsius. Ekutshisweni okuzenzekelayo kwezithuthi zamandla amatsha, iimodeli zebhetri ze-lithium zithatha umlinganiselo omkhulu.

2. Ukuxinana kwamandla

Ngokolwazi loluntu oluvela kwiinkampani zasekhaya, kuqhelekile ukuba iibhetri ze-ternary eziphezulu zibe noxinano olulodwa lwamandla angama-250Wh / kg okanye ngaphezulu, ngelixa ibhetri yasekhaya ye-lithium ye-iron phosphate inomlinganiselo omnye wamandla malunga ne-180Wh / kg.

Ukusuka kulo mbono, ibhetri ye-ternary inoxinano lwamandla olungcono kunebhetri ye-lithium iron phosphate.

Nangona ibhetri yeblade ephuhliswe yi-BYD ikuphucule ukusebenza kakuhle kwebhetri, kunye noxinzelelo lwevolumetric energy lonyuke ukuya kuthi ga kwi-50%, olu lutshintsho lwesakhiwo. Ubuninzi bamandla omntu ngamnye webhetri ye-lithium iron phosphate ayandanga.

3. Ukukhutshwa kweqondo lokushisa eliphantsi

Xa kuthelekiswa, kwi-minus 20 degrees Celsius, iibhetri ze-lithium ze-ternary zineenzuzo ezicacileyo ngaphezu kweebhetri ze-lithium iron phosphate.

Iinkcukacha zibonisiwe kulo mfanekiso ungezantsi:

4. Ukutshaja ngokufanelekileyo

Okwangoku, eyona ndlela ixhaphakileyo yokutshaja kwimarike ihlala ikhoyo ngoku kunye nokutshaja rhoqo kombane. Ngokuqhelekileyo iphunyezwa ekuqaleni kokutshaja. Ukutshaja okuthe rhoqo kusetyenziswa kuqala. Ngeli xesha, ikhoyo inkulu kwaye ukusebenza kakuhle kokutshaja kuphezulu. Xa i-voltage ifikelela kwixabiso elithile, liya kuncipha. I-current iguqulwa ibe yi-voltage yokutshaja rhoqo, ukuze ibhetri ihlawulwe ngokupheleleyo.

Kule nkqubo, umlinganiselo womthamo wokutshaja oqhubekayo ngoku kwixabiso lebhetri lilonke libizwa ngokuba ngumlinganiselo wangoku oqhubekayo, olona xabiso libalulekileyo lokulinganisa ukutshaja kakuhle kweqela leebhetri ngexesha lokutshaja. Ngokuqhelekileyo, ipesenti enkulu, ngakumbi umbane ohlawulelwayo kwinqanaba eliqhubekayo langoku. Okukhona iphezulu, kokukhona kuphezulu ukutshaja kwebhetri kubonakaliswe.

Umlinganiselo wentlawulo epheleleyo kunye nokukhutshwa kwangoku kwibhetri iyonke yintlawulo kunye nesantya sokukhupha. Inokubonwa kwidatha yokuba xa ibhetri ye-lithium ye-ternary kunye ne-lithium iron phosphate ibhetri ihlawuliswa ngezinga elingaphantsi kwamaxesha alishumi, akukho ntlukwano ebalulekileyo kwi-ratio eqhubekayo yangoku. Umlinganiselo oqhubekayo wangoku webhetri ye-iron-lithium uyancipha ngokukhawuleza, kwaye ukusebenza kakuhle kokutshaja kuyancipha ngokukhawuleza. Ingabonwa ukuba ibhetri ye-lithium ye-ternary inenzuzo enkulu malunga nokutshaja ngokufanelekileyo.

5. Ubomi bomjikelo

Ukuba umthamo oseleyo ngu-80% womthamo wokuqala njengokuphela kovavanyo, uvavanyo lwangoku lwebhubhoratri ye-lithium iron phosphate ibhetri inobomi bomjikelezo ongaphezu kwamaxesha angama-3,500, kwaye abanye bafikelele kumaxesha angama-5,000.

Ubomi bomjikelezo wovavanyo lwe-ternary lithium ibhetri malunga namaxesha angama-2500. Kwinqanaba lobomi bomjikelo, ibhetri ye-lithium iron phosphate inobomi bokwenyani obude kakhulu kune-ternary lithium ibhetri.

Ngaphantsi kwenani elifanayo lemijikelo, umthamo oseleyo webhetri ye-lithium iron phosphate ungaphezulu nje kwebhetri ye-ternary lithium. Ibhetri ye-lithium ye-ternary ijikelezwe ngamaxesha angama-3900 kwaye umthamo oseleyo ngu-66%. Ibhetri ye-lithium iron phosphate ijikeleziswa ngamaxesha angama-5000 kwaye amandla asele angama-84%. Ibhetri ye-lithium iron phosphate ineenzuzo ezicacileyo.

Ukususela kuhlalutyo olungentla, kunokubonwa ukuba i-lithium iron phosphate ineenzuzo ezicacileyo malunga nokhuseleko kunye nobomi bomjikelezo; Iibhetri ze-ternary ziphezulu kuxinzelelo lwamandla, ukukhutshwa kobushushu obuphantsi, kunye nokusebenza kakuhle kokutshaja.

Kakade ke, akuthethi ukuba yeyiphi na ibhetri ezimbini ezingcono, kuba zonke zineemeko zabo zokusebenza ezibalaseleyo.
