E pahū a pahū anei nā pākaukau lithium iron phosphate?

I nā makahiki i hala iho nei,nā pākahi lithium-ionua lilo i kumu mana koʻikoʻi no nā ʻano mea uila.Eia naʻe, ʻo nā hopohopo palekana e pili ana i kēia mau pākahi i hoʻāla i ke kūkākūkā o ko lākou mau pilikia.ʻO ka Lithium Iron Phosphate (LiFePO4) kahi kemika pākahi kikoʻī i loaʻa ka nānā ʻana ma muli o kona palekana i hoʻomaikaʻi ʻia i hoʻohālikelike ʻia me nā pā Li-ion kuʻuna.Kūlike ʻole i kekahi mau manaʻo kuhi hewa, ʻaʻole hiki i nā pākahi lithium hao phosphate ke pahū a hoʻoweliweli paha i ke ahi.Ma kēia ʻatikala, manaʻo mākou e hōʻole i kēia ʻike kuhi hewa a wehewehe i nā ʻano palekana o nā ʻāpana LiFePO4.

E aʻo e pili ana i nā pākahi lithium hao phosphate

ʻO ka pākaukau LiFePO4 kahi pākaukau lithium-ion holomua e hoʻohana ana i ka lithium iron phosphate ma ke ʻano he cathode.Hāʻawi kēia kemika i nā pōmaikaʻi nui, e like me ke kiʻekiʻe o ka ikehu kiʻekiʻe, ke ola pōʻai lōʻihi, ka haʻahaʻa haʻahaʻa haʻahaʻa, a ʻo ka mea nui loa, hoʻonui i ka palekana.Ma ka hoʻolālā ʻana, ʻoi aku ka paʻa o nā pākahi lithium iron phosphate a ʻoi aku ka liʻiliʻi o ka holo ʻana o ka wela-he ʻano mea hiki ke alakaʻi i nā pahū a me nā ahi.

ʻEpekema ma hope o ka palekana pākaukau LiFePO4

ʻO kekahi o nā kumu nui i manaʻo ʻia ʻo LiFePO4 ʻoi aku ka palekana ʻo ko lākou ʻano crystalline paʻa.ʻAʻole e like me nā ʻāpana lithium-ion ʻē aʻe nona nā mea cathode he lithium cobalt oxide a i ʻole lithium nickel manganese cobalt (NMC), ʻoi aku ka paʻa o ka LiFePO4.Hāʻawi kēia ʻano crystalline i ka hoʻoheheʻe ʻana o ka wela i ka wā o ka hana ʻana o ka pākaukau, e hōʻemi ana i ka hopena o ka wela a me ka holo ʻana o ka wela.

Eia kekahi, ʻoi aku ka kiʻekiʻe o ka wela hoʻoheheʻe wela ʻo LiFePO4 i hoʻohālikelike ʻia me nā kemika Li-ion ʻē aʻe.'O ia ho'i, hiki i nā pila LiFePO4 ke kū'ē i nā mahana ki'eki'e me ka ho'oha'aha'a'ole i ka wela, e ho'onui ana i ka palena palekana i nā noi like'ole.

Nā hana palekana ma ka hoʻolālā pākaukau LiFePO4

Hoʻohana ʻia nā ʻano palekana like ʻole i ke kaʻina hana o nā pākahi LiFePO4 e hōʻemi i ka pilikia o ka pahū a me ke ahi.Ke kōkua nei kēia mau hana i ka hoʻomaikaʻi ʻana i ka palekana a me ka hilinaʻi holoʻokoʻa o nā ʻaniani LiFePO4.Aia kekahi mau hiʻohiʻona palekana kaulana:

1. ʻO nā electrolytes paʻa: Ke hoʻohana nei nā pākahi LiFePO4 i nā electrolytes hiki ʻole ke puhi ʻia, ʻaʻole e like me nā pā lithium-ion maʻamau e hoʻohana ana i nā electrolytes organic flammable.Hoʻopau kēia i ka hiki ke puhi electrolyte, kahi e hōʻemi nui ai i ke ahi.

2. Pūnaehana hoʻokele pila (BMS): Loaʻa i kēlā me kēia pahu pākahi LiFePO4 kahi BMS, nona nā hana e like me ka pale overcharge, over-discharge protection, a me ka pale kaapuni pōkole.Ke nānā mau nei ka BMS a hoʻoponopono i ka uila uila, ka manawa, a me ka mahana e hōʻoia i ka palekana a me ka maikaʻi o ka hana pākaukau.

3. Ka pale ʻana i ka mahuka: ʻAʻole hiki ke hoʻoheheʻe ʻia nā pila LiFePO4 ma muli o ko lākou kemika palekana.Inā loaʻa kahi hanana koʻikoʻi, hoʻohui pinepine ka hale hana pākaukau lifepo4 i nā mīkini pale wela, e like me nā fuse wela a i ʻole nā ​​hale pale wela, e hōʻemi hou i ka pilikia.

Nā noi a me nā pono o ka pākaukau LiFePO4

Hoʻohana ʻia nā pākahi LiFePO4 i nā ʻano ʻoihana like ʻole, me nā kaʻa uila (EVs), ka mālama ʻana i ka ikehu hou, nā mea uila uila, a me nā mea lapaʻau.ʻO kā lākou palekana i hoʻonui ʻia, lōʻihi, a me ka hilinaʻi e hoʻolilo iā lākou i mea kūpono no ia mau noi koi.

I ka hopena

Kū'ē i ka manaʻo kuhi hewa, ʻaʻohe pilikia o ka pahū a i ke ahi paha nā pila LiFePO4.ʻO kona ʻano aniani paʻa paʻa, ka wela wela decomposition kiʻekiʻe, a me nā ana palekana i hoʻokomo ʻia i loko o ke kaʻina hana e palekana maoli ai.Me ka piʻi nui o ka noi no ka hoʻonā ʻana o ka ikehu holomua, ua hoʻonoho ʻia nā pā lithium iron phosphate ma ke ʻano he koho hilinaʻi a palekana no nā ʻoihana like ʻole.Pono e hoʻoponopono ʻia nā ʻike hewa ʻole e pili ana i ka palekana o ka pākaukau a hoʻolaha ʻia ka ʻike pololei e hōʻoia i ka poʻe e hoʻoholo i ka manaʻo e pili ana i nā koho mana.

Inā makemake ʻoe i nā pākahi lithium iron phosphate, e ʻoluʻolu e hoʻokaʻaʻike i ka hale hana pākaukau lifepo4 Radiance iheluhelu hou.
