Ku ya 16 Gicurasi, Inama mpuzamahanga y’itumanaho rya 4 n’ingufu n’amashanyarazi (CIBF2023 Shenzhen) yafunguwe ku mugaragaro mu kigo mpuzamahanga cy’imurikagurisha n’imurikagurisha (Shenzhen).
Mu gice cyo gutangiza ku mugaragaro, umuyobozi w’iyi nama, Umwarimu w’ishuri ry’ubumenyi ry’Ubushinwa, Ouyang Minggao, yatanze ijambo nyamukuru. Yavuze ko muri rusange, bateri ya lithium fer fosifate ifatwa nk’umutekano muke, kandi cyane cyane, ibi ni ukuri kuri bateri ntoya ya fosifate. Nyamara, kuri bateri nini zifite ubushobozi, ubushyuhe bwimbere bushobora kurenga dogere 800, burenze ubushyuhe bwo kubora ibintu byiza bya electrode nziza ya fosifate ya lithium.
Kuri bateri ntoya, kubera ko hariho urunigi rwerekana hamwe nigice, ibikoresho byiza bya electrode birashobora gutangira kubora gusa iyo bigeze kuri dogere zirenga 500, bityo bateri nto ntabwo ziri mururwo rwego. Ariko bateri nini ya ampere-isaha irashobora kugera kuri dogere 700-900, zishobora gucamo no kurenga iki gice, bigatera kubora ibintu byiza bya electrode. Ubu bateri zibika ingufu zirenga 300 ampere-masaha, aracyari mubi cyane.
Ongera urebeye kuri gaze ya fosifate ya lithium fer, hydrogène yakozwe izagenda yiyongera buhoro buhoro, hamwe no kwiyongera kwa SOC, hydrogenibirimoni hejuru ya 50%, nayo ni akaga cyane. Byongeye kandi, ugereranije ingaruka zishobora gutwikwa kandi ziturika zubwoko bubiri bwa bateri, icyerekezo cyaka kandi giturika cya batiri ya lithium fer fosifate ikubye kabiri iy'amashanyarazi. Batteri ya Ternary ikunda guhura nubushyuhe kandi ikamurika. Litiyumu ya fosifate ya batiri ntishobora kwaka, ariko ibyago byo guturika gaze birenze ibya bateri ya ternary. Iyo ihuye n'ibishashi hanze, ni bibi cyane.
Twese twateye imbere600W, 1200W, na 2000W imbaraga zigendanwa stationskuri ubu birihariye ku isoko kandi nibyo byonyine bikoresha manganese lithium selile ntoya. Impamvu yo guhitamo ihitamo neza cyane cyane no gukurikirana umutekano wanyuma. Muguhitamo lithium ya manganese, ibi bikoresho bidasanzwe byo gukora selile ntoya yoroheje, irashobora kugabanya ingaruka zishobora guhungabanya umutekano kandi ikemeza ko ishobora guha abayikoresha ingwate zumutekano zizewe mubihe bitandukanye byakoreshejwe, ikirinda ibihe bibi nko guturika gaze bishobora kuba binini ubushobozi bumwe na bunini bwa lithium fer fosifate, kimwe n’akaga kihishe kazanwa no kwikuramo ubushyuhe bwa bateri ya ternary, bityo bigatera uburambe bwabakoresha amahoro kandi nta mpungenge kubakoresha.
