Musi waMay 16, 4th New Energy Vehicles uye Power Battery (CIBF2023 Shenzhen) International Communication Conference yakavhurwa zvakanaka paShenzhen International Convention uye Exhibition Center (Horo Itsva).
Muchikamu chemhemberero dzekuvhura, sachigaro wemusangano uyu, Academician weChinese Academy of Sciences, Ouyang Minggao, akaita hurukuro inokosha. Akataura kuti kazhinji, lithium iron phosphate mabhatiri anoonekwa seakachengeteka, uye zvakanyanya, izvi ndezvechokwadi kune madiki lithium iron phosphate mabhatiri. Zvisinei, kune mabhatiri makuru ekukwanisa, kupisa kwemukati kunogona kudarika 800 degrees, iyo inopfuura tembiricha yekuparara kweiyo positive electrode material ye lithium iron phosphate.
Kune mabhatiri madiki madiki, nekuti kune ketani inopindirana ine kupatsanurwa, iyo yakanaka electrode zvinhu inogona kungotanga kuora kana inosvika madhigirii anopfuura 500, saka mabhatiri madiki haasi mukati merudzi urwu. Asi mabhatiri makuru e-ampere-awa anogona kusvika 700-900 madhigirii, anogona kupaza nekuyambuka ichi chikamu, zvichikonzera kuparara kweiyo yakanaka electrode zvinhu. Iye zvino mabhatiri ekuchengetedza simba ari kunyanya kudarika 300 ampere-maawa, izvo zvichiri nengozi.
Tichitarisa zvakare kugadzirwa kwegasi ye lithium iron phosphate, iyo hydrogen inogadzirwa ichawedzera zvishoma nezvishoma, uye nekuwedzera kweSOC, iyo hydrogen.contentinopfuura 50%, iyo inewo ngozi zvikuru. Mukuwedzera, kuenzanisa njodzi dzinopisa uye dzinoputika dzemhando mbiri dzebhatiri, iyo inopfuta uye inoputika indekisi ye lithiamu iron phosphate mabhatiri inopeta kaviri yebhatiri reternary. Mabhatiri eTernary anowanzoita kupisa kwemhepo uye anovhenekera ivo pachavo. Lithium iron phosphate mabhatiri haakwanise kuzvivhenekera, asi njodzi yekuputika kwegasi yakakwira kupfuura iyo yemabhatiri eternary. Kana yangosangana nepfarivari panze, inenge ine ngozi.
Yedu ichangobva kusimukira600W, 1200W, uye 2000W inotakurika simba stationsparizvino akasiyana mumusika uye ndidzo chete dzinoshandisa manganese lithium diki masero. Chikonzero chekuita sarudzo iyi yakanyatsoenderana nekutsvaga kwekupedzisira kwekuchengetedza. Nekusarudza manganese lithium, iyi yakakosha zvinhu kugadzira madiki akapfava mapaketi maseru, anogona kuderedza angangoita njodzi dzekuchengetedza uye kuona kuti inogona kupa vashandisi vimbiso dzekuchengetedza dzakavimbika mumamiriro akasiyana ekushandisa, kudzivirira mamiriro ane njodzi sekuputika kwegasi kunogona kuitika muhombe. imwe uye yakakura simba lithium iron phosphate mabhatiri, pamwe chete nenjodzi dzakavanzwa dzinounzwa ne-self-thermal runaway yemabhatiri e-ternary, nokudaro kuumba ruzivo rune rugare uye rusina kunetseka rwevashandisi kune vashandisi.
