Ngomhla ziyi-16 kuNhlaba, Ingqungquthela Yesine Yezinqola Zamandla Amasha Nebhethri Lamandla (CIBF2023 Shenzhen) yavulwa kahle eNgqungqutheleni Yezizwe Ngezizwe Nezimboni zase-Shenzhen (Ihholo Elisha).
Esigabeni somcimbi wokuvula, usihlalo wale ngqungquthela, i-Academician of the Chinese Academy of Sciences, u-Ouyang Minggao, wenze inkulumo eyisihluthulelo.Uthe ngokujwayelekile, amabhethri e-lithium iron phosphate athathwa njengaphephile, futhi empeleni lokhu kuyiqiniso kumabhethri amancane e-lithium iron phosphate.Kodwa-ke, ngamabhethri amakhulu, izinga lokushisa langaphakathi lingadlula ama-degree angu-800, elidlula izinga lokushisa lokubola kwezinto ezibonakalayo ze-electrode ye-lithium iron phosphate.
Kumabhethri anosayizi omncane, ngenxa yokuthi kukhona ukusabela kweketango ngokuhlukaniswa, into esebenzayo ye-electrode ingase iqale ukubola lapho ifinyelela ngaphezu kwamadigri angu-500, ngakho-ke amabhethri amancane awekho ngaphakathi kwalolu hlu.Kodwa amabhethri amakhulu ehora le-ampere angase afinyelele ku-700-900 degrees, angase agqekeze futhi awele lokhu kuhlukaniswa, okubangela ukubola kwezinto ezibonakalayo ze-electrode.Manje amabhethri okugcina amandla ngokuyisisekelo angaphezulu kwamahora angu-300 ampere, okuseyingozi kakhulu.
Uma sibheka futhi ukukhiqizwa kwegesi ye-lithium iron phosphate, i-hydrogen ekhiqizwayo izokhula kancane kancane, futhi ngokwanda kwe-SOC, i-hydrogen.okuqukethweingaphezu kuka-50%, nayo eyingozi kakhulu.Ukwengeza, uma kuqhathaniswa nezingozi ezivuthayo neziqhumane zezinhlobo ezimbili zamabhethri, inkomba evuthayo neqhumayo yamabhethri e-lithium iron phosphate iphindwe kabili kunamabhethri e-ternary.Amabhethri e-ternary athambekele ekubalekeni okushisayo futhi azikhanyise wona.Amabhethri e-lithium iron phosphate awakwazi ukuzikhanyisa, kodwa ingozi yokuqhuma kwegesi iphezulu kunaleyo yamabhethri e-ternary.Uma ihlangana nezinhlansi ngaphandle, iyingozi kakhulu.
Eyethu esanda kuthuthukiswa600W, 1200W, kanye no-2000W amandla aphathekayo stationsokwamanje zihlukile emakethe futhi yizo kuphela ezisebenzisa amaseli amancane esikhwama se-manganese lithium.Isizathu sokwenza lokhu kukhetha sisekelwe ngokunembile ekuphishekeleni kokugcina kokuphepha.Ngokukhetha i-manganese lithium, le nto ebalulekile yokwenza amaseli ephakethe elithambile, inganciphisa izingozi ezingaba khona zokuphepha futhi iqinisekise ukuthi inganikeza abasebenzisi iziqinisekiso zokuphepha ezinokwethenjelwa ezimeni ezihlukahlukene zokusetshenziswa, igweme izimo eziyingozi ezifana nokuqhuma kwegesi okungase kwenzeke ezindaweni eziningi. umthamo owodwa kanye nomkhulu amabhethri e-lithium iron phosphate, kanye nezingozi ezifihliwe ezilethwa ukubaleka okuzifudumezayo kwamabhethri e-ternary, ngaleyo ndlela kudala ulwazi lomsebenzisi olunokuthula nolungenakukhathazeka kubasebenzisi.
