Ukugcinwa kwamandla usebenzisa i-lithium iron phosphate ibhetri ipakethi ikhuselekile okanye akunjalo? Xa kuziwa kwiibhetri ze-lithium iron phosphate, siya kuqala sixhalabele ngokukhuselekileyo kwayo, kulandele ukusetyenziswa kwayo kokusebenza. Kwisicelo esisebenzayo sokugcinwa kwamandla, ukugcinwa kwamandla kufuna ukusebenza okuphezulu kokhuseleko, ubomi bomjikelezo ophezulu, ixabiso eliphantsi leebhetri ze-lithium. Ke, ibhetri ye-lithium iron phosphate ikhuselekile okanye akunjalo? Kweli phepha, i-XUANLI inyanzelise umhleli we-elektroniki ukuba akuthathe ukuba ufumanise.
E-China, imigaqo-nkqubo iye yaziswa kutshanje ukukhuthaza nokulawula uphuhliso lokugcinwa kwamandla kunye nokubeka phambili iimfuno zemigangatho yokhuseleko efanelekileyo. Ukugcinwa kwamandla e-electrochemical amandla okuthintela ingozi yomlilo, iimfuno ezicacileyo zibekwe phambili, kubandakanywa.
(1) i-electrochemical energy yokugcina amandla aphakathi kunye nenkulu ayiyi kukhetha iibhetri ze-lithium ze-ternary, iibhetri ze-sodium-sulfur, akufanele zikhethe ukusetyenziswa kweebhetri zamandla esibini;
(2) ukukhethwa kokusetyenziswa kwesibini kweebhetri zamandla, kufuneka kuhlolwe rhoqo kwaye kudibaniswe nedatha yokulandelelwa kovavanyo lokhuseleko;
(3) Igumbi lezixhobo zebhetri ye-lithium-ion kufuneka libe lilungiselelo le-single-layer, ngokukhethekileyo kusetyenziswa uhlobo lwekhabhinethi elungiselelwe ngaphambili.
Ingaba yinkqubo enkulu yokugcina amandla ehlabathi esebenzisa iibhetri ze-lithium ze-ternary, okanye i-lithium ye-iron phosphate yangoku yaseChina, iinkqubo zokugcina amandla kufuneka zibuyele kwezona zinto zikhuselekileyo zisisiseko, sisiseko sophuhliso.
Kwiminyaka yakutshanje, iteknoloji ye-lithium ye-phosphate ikhulile ngokupheleleyo, kunye neebhetri ze-lithium ze-lithium, iibhetri ze-lithium iron phosphate azinayo imingcipheko yokhuseleko, ephezulu kunokhuseleko lweebhetri ze-lead-acid. Oku kulandelayo kukuthelekiswa kweempawu eziphambili ze-lithium iron phosphate materials kunye ne-ternary materials.
Njengoko uyazi, ibhetri esetyenziselwa ukugcina amandla idinga ubomi obude, ukhuseleko oluphezulu kunye neendleko eziphantsi. Nangona uxinano lwamandla ebhetri ye-lithium iron phosphate iphantsi, kodwa ukusebenza kwayo okuphezulu kobushushu, eyona nto ibalulekileyo kukuzinza kwe-thermal kukusebenza kakuhle kokhuseleko, ubomi obude, kwaye okwangoku, xa kuthelekiswa, iindleko zayo ziphantsi kune-ternary.
Ngokumalunga nezixhobo ze-ternary, inomthamo ophezulu wegram kunye neqonga eliphezulu lokukhupha, oku kuthetha ukuxinana kwamandla aphezulu. Ukusebenza kwayo okuphantsi kweqondo lokushisa kungcono, ukusebenza kobushushu obuphezulu kuqhelekileyo, ukuzinza kwe-thermal kuqhelekileyo, ukusebenza kokhuseleko kukwabanzi.
Ukusuka kumbono opheleleyo, ukusuka kwiimfuno zokugcina amandla okhuseleko oluphezulu, ubomi obude, ixabiso eliphantsi, i-lithium iron phosphate ibhetri ipakethe yeyona nto ilungileyo yokukhetha izixhobo zokugcina amandla.
Ipakethi yebhetri ye-lithium ye-iron phosphate ineenzuzo zokhuseleko kunye nokuthembeka, ubomi benkonzo ende, unyawo oluncinci, ukusebenza okulula kunye nokugcinwa. Imveliso ithatha iseli yebhetri ye-lithium ye-iron phosphate, inkqubo yayo yokuvelisa ithatha izixhobo ezizenzekelayo ngokupheleleyo, kunye nokuhambelana kwemveliso engcono, akukho kuqhuma kwaye akukho mlilo, eyona ibhetri ikhuselekileyo kwibhetri ye-lithium.
Ukutshaja kunye nokukhupha zizinto ezimbini ezisisiseko zokusebenza kweebhetri ze-lithium. Xa i-lithium iron phosphate ibhetri itshaja kwaye ikhupha, ngenxa yokuba i-iron ion oxidation inamandla, ayiyi kukhulula i-oksijini, kunzima ngokwemvelo ukwenzeka nge-electrolyte redox reaction, eyenza i-lithium iron phosphate ibhetri yokutshaja kunye nenkqubo yokukhupha. indawo ekhuselekileyo. Akunjalo kuphela, ibhetri ye-lithium ye-iron phosphate kwi-multiplier discharge enkulu, kunye nokugqithiswa kunye nenkqubo yokukhupha, kunzima ukwenzeka kwi-reaction redox enobudlova.
Ngelo xesha, i-lithium kwi-de-embedding, i-lattice itshintshe ukwenzela ukuba iseli (iyunithi encinci ye-crystal composition) ekugqibeleni iya kuncipha ngobukhulu, nto leyo isusa nje ukunyuka komthamo we-carbon cathode ekuphenduleni, ngoko. ukuhlawulwa kunye nokukhutshwa kwebhetri ye-lithium yentsimbi ye-phosphate inokugcina ukuzinza kwesakhiwo somzimba, ukuphelisa amandla okunyusa umthamo kunye nesiganeko sokuqhuma kwebhetri.
Iteknoloji entsha ye-lithium-ion yophuhliso lwebhetri yokhuseleko ibalulekile, enxulumene nophuhliso lwexesha elizayo lwesikali se-lithium yokugcina amandla ixesha elide. Ukugcinwa kwamandla e-lithium iron phosphate ibhetri yokhuseleko oluphezulu, ixabiso eliphantsi, elizinzileyo yinjongo yophuhliso oluqhelekileyo lwamashishini, kodwa kwakhona imboni yokugcina amandla idinga ulwalathiso olubalulekileyo lokuhlaselwa.
