Ma Mei 16, ua wehe nui ʻia ka 4th New Energy Vehicles and Power Battery (CIBF2023 Shenzhen) International Communication Conference ma ka Shenzhen International Convention and Exhibition Center (New Hall).
Ma ka ʻāpana o ka wehe ʻana, ua haʻi ka luna o kēia ʻaha kūkā, ʻo Academician o ka Chinese Academy of Science, ʻo Ouyang Minggao, i kahi ʻōlelo nui. Ua ʻōlelo ʻo ia ma ke ʻano maʻamau, ua manaʻo ʻia nā pākahi lithium iron phosphate he palekana, a ʻo ka mea nui, he ʻoiaʻiʻo kēia no nā pākahi liʻiliʻi lithium iron phosphate. Eia nō naʻe, no ka nui o nā ʻeke uila, hiki i ka mahana o loko ke ʻoi aku ma mua o 800 degere, ʻoi aku ka nui o ka mahana no ka decomposition o nā mea electrode maikaʻi o ka lithium iron phosphate.
No nā pila liʻiliʻi, no ka mea aia ke kaulahao me ka pā, hiki ke hoʻomaka wale ka mea electrode maikaʻi e decompose ke piʻi ʻo ia ma mua o 500 degere, no laila ʻaʻole i loko o kēia pae. Akā hiki ke piʻi ʻia nā ʻeke ampere-hour nui i ka 700-900 degere, hiki ke uhaʻi a hele i kēia ʻāpana, e hoʻoheheʻe ʻia ka mea electrode maikaʻi. I kēia manawa, ʻoi aku ka nui o nā pihi mālama ikehu ma mua o 300 ampere-hola, a he mea weliweli loa ia.
Ke nānā hou nei i ka hana kinoea o ka lithium iron phosphate, e piʻi mālie ka hydrogen i hana ʻia, a me ka piʻi ʻana o SOC, ka hydrogen.maʻiʻoʻoi aku ma mua o 50%, he mea weliweli loa. Eia kekahi, ke hoʻohālikelike ʻana i nā pōʻino pahū a me ka pahū ʻana o nā ʻano ʻelua o nā ʻāpana, ʻo ka helu ʻana a me ka pahū o nā pā lithium hao phosphate he ʻelua ʻoi aku ka nui o nā pākahi ternary. Hiki ke hoʻomāmā a hoʻomālamalama ʻia nā ʻoihana ʻo Ternary. ʻAʻole hiki ke hoʻomālamalama i nā pā hao hao phosphate iā lākou iho, akā ʻoi aku ka kiʻekiʻe o ka pahū kinoea ma mua o nā pihi ternary. Ke hālāwai ʻo ia i nā ʻōhū ma waho, ʻoi aku ka pōʻino.
ʻO kā mākou kūkulu hou600W, 1200W, a me 2000W mana lawe stationsi kēia manawa kūʻokoʻa i ka mākeke a ʻo ia wale nō ka poʻe e hoʻohana nei i nā ʻeke liʻiliʻi lithium manganese. ʻO ke kumu o ka hana ʻana i kēia koho ma muli o ka ʻimi hope loa o ka palekana. Ma ke koho ʻana i ka lithium manganese, ʻo kēia mea kūikawā e hana i nā pūnaewele liʻiliʻi liʻiliʻi liʻiliʻi, hiki iā ia ke hōʻemi i nā pilikia palekana palekana a hōʻoia i hiki iā ia ke hāʻawi i nā mea hoʻohana i nā hōʻoia palekana hilinaʻi i nā hiʻohiʻona hoʻohana like ʻole, e pale aku i nā kūlana pōʻino e like me nā pahū kinoea e hiki mai ana i ka nui. ʻO nā pākahi lithium hao phosphate hoʻokahi a nui, a me nā pōʻino huna i lawe ʻia mai e ka holo ʻana o ka wela wela o nā ʻanuʻu ternary, pēlā e hana ai i kahi mea hoʻohana maluhia a hopohopo ʻole no nā mea hoʻohana.
