He aha ka haʻahaʻa wela pākaukau? ʻO nā pono a me nā hana o nā pā lithium haʻahaʻa haʻahaʻa
By hoppt
Nui nā hoaaloha i nā nīnau i ko lākou lohe ʻana i ka pane mua ʻana o nā pākahi haʻahaʻa haʻahaʻa: He aha ke ʻano haʻahaʻa haʻahaʻa? Aia kekahi hoʻohana?
He aha ke ʻano haʻahaʻa haʻahaʻa haʻahaʻa?
ʻO ka pākaukau haʻahaʻa haʻahaʻa kahi pākaukau kū hoʻokahi i hoʻomohala kūikawā no nā hemahema haʻahaʻa haʻahaʻa i loaʻa i ka hana o nā kumu mana kemika. ʻO ka pākaukau haʻahaʻa wela hoʻohana i ka VGCF a me ke kalapona i hoʻāla ʻia me kahi ʻāpana kiko o
ʻO nā ʻokoʻa haʻahaʻa haʻahaʻa e pili ana i nā pākahi lithium-ion nona ka mahana hana ma lalo o -40°C. Hoʻohana nui ʻia lākou i ka aerospace pūʻali koa, nā mea i kau ʻia i nā kaʻa, ka noiʻi ʻepekema a me ka hoʻopakele, nā kamaʻilio mana, ka palekana o ka lehulehu, nā uila uila, nā alahao, nā moku, nā robots, a me nā kahua ʻē aʻe. Hoʻokaʻawale ʻia nā pākahi lithium haʻahaʻa haʻahaʻa e like me kā lākou hana hoʻokuʻu ʻana: ka mālama ʻana i ka ikehu, nā pākahi lithium haʻahaʻa haʻahaʻa, a me nā pā lithium haʻahaʻa haʻahaʻa haʻahaʻa. Wahi a nā kahua noi, ua hoʻokaʻawale ʻia nā pākahi lithium haʻahaʻa haʻahaʻa i nā pā lithium haʻahaʻa haʻahaʻa no ka hoʻohana pūʻali koa a me nā ʻoihana lithium haʻahaʻa haʻahaʻa haʻahaʻa. Ua māhele ʻia kona wahi hoʻohana i ʻekolu moʻo: ʻo nā ʻokoʻa kīwila haʻahaʻa haʻahaʻa haʻahaʻa, nā ʻokoʻa haʻahaʻa haʻahaʻa kūikawā, a me nā ʻona wela haʻahaʻa o ke kaiapuni.
ʻO nā wahi hoʻohana o nā pāhana haʻahaʻa haʻahaʻa ka nui o nā mea kaua, aerospace, missile-borne kaʻa lako, polar science research, frigid rescue, power communications, public safety, medical electronics, railways, ships, robots, and other fields.
ʻO nā pono a me nā hana o nā pā lithium haʻahaʻa haʻahaʻa
Loaʻa i nā ʻeke lithium haʻahaʻa haʻahaʻa nā pōmaikaʻi o ka māmā, ka ikehu kikoʻī kiʻekiʻe, a me ka lōʻihi a hoʻohana nui ʻia i nā mea uila like ʻole. I waena o lākou, ʻo ka haʻahaʻa haʻahaʻa haʻahaʻa polymer lithium-ion pākaukau i loaʻa nā mea maikaʻi o ka hoʻopili maʻalahi, maʻalahi e hoʻololi i ke ʻano geometric o ka ʻino, ultra-light a me ultra-thin, a me ka palekana kiʻekiʻe. Ua lilo ia i kumu mana no nā huahana uila uila.
ʻAʻole hiki iā ia ke hoʻohana i nā pākahi kīwila maʻamau ma -20°C, a hiki nō ke hoʻohana i nā pā lithium haʻahaʻa haʻahaʻa, maʻamau ma -50°C. I kēia manawa, hoʻohana maʻamau ʻia nā ʻuala haʻahaʻa haʻahaʻa i kahi kaiapuni o ℃ a i lalo paha. Ma waho aʻe o nā lako mana kamaʻilio, nā lako uila lawe lima pūʻali koa, nā lako mana hōʻailona, a me nā lako mana liʻiliʻi e hoʻokele ai i nā lako mana e pono ai ka hoʻohana ʻana i nā pihi haʻahaʻa haʻahaʻa. Loaʻa i kēia mau lako mana nā koi hana haʻahaʻa haʻahaʻa i ka wā e hana ai i ke kula.
ʻO nā papahana ʻimi lewa e like me ka lele mokulele a me ka papahana pae ʻana o ka mahina e hoʻokō ʻia nei ma Kina e koi pū kekahi i nā kumu mana mālama mālama ikehu kiʻekiʻe, ʻoi aku ka haʻahaʻa haʻahaʻa lithium pākaukau. No ka mea, ʻoi aku ka paʻakikī o nā huahana kamaʻilio pūʻali koa i nā ʻano pākaukau, ʻoi aku ka koi ʻana i nā hōʻoia kamaʻilio ma nā haʻahaʻa haʻahaʻa. No laila, he mea koʻikoʻi ka hoʻomohala ʻana o nā pā lithium haʻahaʻa haʻahaʻa i ka hoʻomohala ʻana o nā ʻoihana koa a me nā aerospace.
Hoʻohana nui ʻia nā pākahi lithium haʻahaʻa haʻahaʻa ma muli o ko lākou māmā, ikaika kikoʻī kiʻekiʻe, a me ke ola lōʻihi. Hana ʻia nā pākahi lithium haʻahaʻa haʻahaʻa i nā mea kūʻokoʻa a me nā kaʻina hana a kūpono no ka hoʻohana ʻana i nā wahi anuanu sub-zero.
Ua hoʻomohala maikaʻi nā mea ʻenekinia ma ke Kulanui o Kaleponi, San Diego, i kahi haʻahaʻa haʻahaʻa lithium iron phosphate lithium-ion pā uila e hiki ke mālama i ka hana ma ka lumi wela ma kahi haʻahaʻa haʻahaʻa o 60°C. I kēia manawa, ʻo nā ʻano o nā pā haʻahaʻa haʻahaʻa i hiki ke kau ʻia ma ka mākeke me ka nui o nā pākahi lithium hao phosphate haʻahaʻa haʻahaʻa a me nā pā lithium haʻahaʻa haʻahaʻa polymer. ʻO kēia mau ʻano ʻelua o nā ʻenehana pākahi haʻahaʻa haʻahaʻa.
Nā hiʻohiʻona o ka haʻahaʻa haʻahaʻa lithium iron phosphate pākaukau
- Hana maikaʻi haʻahaʻa haʻahaʻa: hoʻokuʻu ma 0.5C ma -40 ℃, ʻoi aku ka nui o ka hoʻokuʻu ʻana ma mua o 60% o ka huina mua; ma -35 ℃, pohā ma 0.3C, ʻoi aku ka nui o ka hoʻokuʻu ʻana ma mua o 70% o ka huina mua;
- Laulā wela hana, -40 ℃ a 55 ℃;
- ʻO ka wela haʻahaʻa pākahi lithium hao phosphate he 0.2c ka ho'āʻo pōʻaiapuni hoʻokuʻu ma -20°C. Ma hope o 300 mau pōʻai, aia nō ka nui o ka mālama ʻana ma mua o 93%.
- Hiki iā ia ke hoʻokuʻu i ka pihi hoʻokuʻu o nā pā haʻahaʻa lithium iron phosphate ma nā wela like ʻole ma -40 ° C a 55 ° C.
ʻO ka pākaukau lithium iron phosphate haʻahaʻa haʻahaʻa he ʻenehana hou i hoʻomohala ʻia ma hope o ka noiʻi lōʻihi a me ka hoʻomohala ʻana a me ka hoʻāʻo. Hoʻohui ʻia nā mea maka kūikawā i ka electrolyte. ʻO ka maikaʻi o nā mea waiwai a me ka ʻenehana e hōʻoia i ka hoʻokuʻu ʻana i ka hana kiʻekiʻe o ka pākaukau ma nā mahana pāpaʻu. Hoʻohana nui ʻia kēia pākaukau lithium iron phosphate haʻahaʻa haʻahaʻa i nā kahua haʻahaʻa haʻahaʻa e like me nā mea kaua, ʻoihana aerospace, nā mea luʻu, polar ʻepekema noiʻi, kamaʻilio mana, palekana lehulehu, nā mea uila, etc.
