ʻO nā pōmaikaʻi o nā pākahi lithium iron phosphate

1. Hoʻomaikaʻi i ka hana palekana

ʻO ka palapala PO i loko o ka lithium hao phosphate crystal he paʻa a paʻakikī ke hoʻoheheʻe.ʻOiai i ka wela kiʻekiʻe a i ʻole ka hoʻonui ʻana, ʻaʻole ia e hāʻule a hoʻohua i ka wela e like me ka lithium cobalt oxide a i ʻole e hana i nā mea hoʻoneʻe ikaika, no laila he palekana maikaʻi.Ua hōʻike ʻia kahi hōʻike ma ka hana maoli, ua ʻike ʻia kahi helu liʻiliʻi o nā laʻana e ʻā ana i ka acupuncture a i ʻole nā ​​hoʻokolohua pōkole pōkole, akā ʻaʻohe pahū.mea pahū.Eia nō naʻe, ua hoʻomaikaʻi maikaʻi ʻia kona palekana overcharge i hoʻohālikelike ʻia me nā pākahi wai electrolyte lithium cobalt oxide maʻamau.

2. Hoʻonui i ke ola

ʻO ka pākaukau lithium iron phosphate e pili ana i kahi pākahi lithium ion e hoʻohana ana i ka lithium iron phosphate ma ke ʻano he mea electrode maikaʻi.

ʻO ke ola pōʻaiapuni o nā pākini lead-acid lōʻihi ma kahi o 300 mau manawa, a ʻo ka nui loa he 500 mau manawa, ʻoiai ke ola pōʻaiapuni o nā pā uila lithium hao phosphate hiki ke piʻi aku ma mua o 2,000 mau manawa, a me ka hoʻopiʻi maʻamau (5-hola helu) hiki ke hoʻohana i 2,000 manawa.ʻO ka pākaukau alakaʻi-acid o ka maikaʻi like ʻo "ka hapalua makahiki hou, ka hapalua makahiki, a me ka mālama ʻana a me ka mālama ʻana no ka hapalua makahiki", ʻo ia ka 1 ~ 1.5 mau makahiki i ka hapa nui, a hoʻohana ʻia ka pākaukau lithium hao phosphate ma lalo o nā kūlana like. ke ola theoretical e hiki i 7 ~ 8 makahiki.ʻO ka noʻonoʻo holoʻokoʻa, ʻoi aku ka nui o ke kumu kūʻai hana ma mua o 4 mau manawa o nā pākī lead-acid.Hiki i ka hoʻokuʻu kiʻekiʻe ke hoʻouka a hoʻokuʻu i ka 2C kiʻekiʻe.Ma lalo o ke kauā kūikawā, hiki ke hoʻopiha piha ʻia ka pākaukau i loko o 40 mau minuke o ka hoʻopiʻi ʻana o 1.5C, a hiki i ka manawa hoʻomaka ke piʻi i 2C, akā ʻaʻole i loaʻa kēia hana i nā pākaʻi lead-acid.

3. Hana maikaʻi wela wela

Hiki ke piʻi ka piko hoʻomehana uila o ka lithium iron phosphate i 350 ℃-500 ℃, aʻo ka lithium manganate a me ka lithium cobaltate ma kahi o 200 ℃.ʻO ka laulā wela o ka hana ākea (-20C–75C), me ke kūpaʻa wela kiʻekiʻe, hiki i ka piko hoʻomehana uila o ka lithium hao phosphate ke hiki i 350 ℃-500 ℃, aʻo ka lithium manganate a me ka lithium cobaltate ma kahi o 200 ℃.

4. Ka mana nui

Hoʻohana pinepine ʻia nā pila ma lalo o ke ʻano o ka hoʻopiha piha ʻana, a e hāʻule koke ka mana ma lalo o ka mana helu.Kapa ʻia kēia hanana i ka hopena hoʻomanaʻo.E like me ka nickel-metal hydride a me ka nickel-cadmium batteries, aia ka hoʻomanaʻo, akā ʻaʻole i loaʻa kēia ʻano mea i nā pā lithium hao phosphate.No ke ʻano o ke kūlana o ka pākaukau, hiki ke hoʻohana ʻia i kēlā me kēia manawa me ka ʻole o ka hoʻokuʻu ʻana ma mua o ke kau ʻana.

5. Ke kaumaha māmā

ʻO ka nui o ka pākaukau lithium iron phosphate me ka kikoʻī like a me ka hiki ke 2/3 o ka nui o ka pahu lead-acid, a ʻo ke kaumaha ʻo 1/3 o ka pākaukau lead-acid.

6. Hoomalu kaiapuni

Manaʻo pinepine ʻia nā pā hao phosphate Lithium me ka ʻole o nā metala kaumaha a me nā metala laha ʻole (pono nā ʻāpana nickel-metal hydride i nā metala liʻiliʻi), non-toxic (SGS certified), ʻaʻole haumia, hoʻokō me nā lula RoHS ʻEulopa, a he mea paʻa loa. palapala ʻōmaʻomaʻo pākahiko.No laila, ʻo ke kumu i makemake nui ʻia ai ka pākaukau lithium e ka ʻoihana ma muli o ka noʻonoʻo ʻana i ka mālama ʻana i ke kaiapuni.No laila, ua hoʻokomo ʻia ka pākaukau i loko o ka papahana hoʻomohala ʻenehana kiʻekiʻe "863" i ka wā o ka manawa "Tenth Five-Year Plan", a ua lilo ia i papahana nui i kākoʻo ʻia a paipai ʻia e ka mokuʻāina.Me ke komo ʻana o Kina i ka WTO, e piʻi wikiwiki ana ka nui o nā paikikala uila o Kina, a ua koi ʻia nā kaʻa uila e komo ana i ʻEulopa a me ʻAmelika Hui Pū ʻIa me nā ʻuila ʻaʻole haumia.

Eia nō naʻe, ua ʻōlelo kekahi poʻe loea ʻo ka hoʻohaumia ʻana i ke kaiapuni i hoʻokumu ʻia e nā pākaʻi lead-acid ka mea nui i loko o ke kaʻina hana maʻamau a me ke kaʻina hana hou o nā ʻoihana.Ma keʻano like, pili nā pā lithium i ka ʻoihana ikehu hou, akā ʻaʻole hiki ke pale i ka pilikia o ka pollution metala kaumaha.Hiki ke hoʻokuʻu ʻia ke alakaʻi, arsenic, cadmium, mercury, chromium, etc. i ka hana ʻana i nā mea metala i ka lepo a me ka wai.ʻO ka pākaukau ponoʻī he mea kemika, no laila hiki ke kumu i ʻelua ʻano haumia: hoʻokahi ke kaʻina hana hoʻohaumia ʻōpala i ka papahana hana;ʻo ka pollution ʻē aʻe ma hope o ka ʻoki ʻana.

Loaʻa nā hemahema o nā pā hao hao phosphate: no ka laʻana, maikaʻi ʻole ka hana haʻahaʻa haʻahaʻa, haʻahaʻa ka tap density o nā mea electrode maikaʻi, a ʻoi aku ka nui o nā pā lithium hao phosphate o ka mana like ma mua o nā pā lithium ion e like me ka lithium. ʻO ka cobalt oxide, no laila ʻaʻohe ona mea maikaʻi i nā ʻeke micro.Ke hoʻohana ʻia i nā pihi mana, pono nā pā lithium iron phosphate, e like me nā pihi ʻē aʻe, e kū i ka pilikia o ka paʻa ʻana o ka pākaukau.
