No nā ʻano noi like ʻole, makemake nui ʻia nā pihi mana kiʻekiʻe i kēia lā.He nui nā noi o kēia mau pila, e like me ka lā, kaʻa uila, a me nā ʻeke leʻaleʻa.ʻO nā pākaʻi ʻakika-lead wale nō ka mea i koho ʻia ma ka mākeke a hiki i kekahi mau makahiki i hala.ʻO ka makemake no nā pākaukau lithium-based ua loli nui i ka mākeke o kēia manawa, ʻoiai naʻe, ma muli o kā lākou noi.

ʻO ka pākaukau lithium-ion a me ka lithium Iron phosphate (LiFePO4) ke kū nei ka pākaukau ma waena o nā mea ʻē aʻe ma kēia ʻano.Nīnau pinepine ka poʻe e pili ana i ka ʻokoʻa ma waena o nā ʻāpana ʻelua no ka mea he lithium-based.

ʻO ka hopena, e nānā hohonu mākou i kēia mau ʻāpana i kēia ʻāpana a kūkākūkā pehea lākou e ʻokoʻa ai.Ma ke aʻo ʻana e pili ana i kā lākou hana ma nā kumu like ʻole, e loaʻa iā ʻoe ka ʻike hou aʻe i ke ʻano o ka pākaukau e hana maikaʻi loa iā ʻoe.Me ka ʻole o ka liʻiliʻi, e hoʻomaka kākou:

No ke aha i ʻoi aku ka maikaʻi o nā Bateri LiFePO4:

Ke nānā nei nā mea hana ma nā ʻoihana like ʻole i ka lithium iron phosphate no nā noi kahi mea nui ka palekana.ʻO ke kemika maikaʻi a me ka lōʻihi wela ka waiwai o ka lithium iron phosphate.Ma nā wahi wela, mālama kēia pākaukau i kona ʻoluʻolu.

ʻAʻole hiki ke puhi ʻia ke mālama pono ʻole ʻia i ka wā o ka hoʻopiʻi wikiwiki a me ka hoʻokuʻu ʻana a i ʻole ke kū mai nā pilikia kaapuni pōkole.Ma muli o ka pale ʻana o ka cathode phosphate i ke ahi a pahū paha i ka wā o ka hoʻouka ʻana a i ʻole ka wela nui a me ka hiki o ka pākaukau e mālama i nā mahana mālie, ʻaʻole ʻike pinepine ʻia nā pākahi lithium hao phosphate i ka holo wela.

Eia nō naʻe, ʻoi aku ka maikaʻi o nā pono palekana o ka lithium-ion battery chemistry ma mua o ka mea o ka lithium iron phosphate.Hiki ke hilinaʻi nui ʻia ka pākaukau ma muli o kona kiʻekiʻe o ka ikehu, ʻo ia ka drawback.Ma muli o ka maʻalahi o ka pākaukau lithium-ion i ka mahuka wela, ʻoi aku ka wikiwiki o ka pumehana i ke kau ʻana.ʻO ka wehe ʻana o ka pākaukau ma hope o ka hoʻohana ʻana a i ʻole ka hana ʻino ʻana kekahi pono o ka lithium iron phosphate ma ke ʻano o ka palekana.

ʻO ka kemika lithium cobalt dioxide i hoʻohana ʻia i loko o nā pā lithium-ion he mea weliweli ia no ka mea hiki ke hōʻike i ka poʻe i nā pane maʻi i ko lākou mau maka a me ka ʻili.Ke ale ʻia, hiki ke hopena i nā pilikia olakino koʻikoʻi.ʻO ka hopena, pono nā pākaukau lithium-ion i nā pilikia hoʻolei kūikawā.Eia nō naʻe, hiki i nā mea hana ke hoʻopau maʻalahi i ka lithium iron phosphate no ka mea ʻaʻole ia he mea make.

ʻO ka hohonu o ka hoʻokuʻu ʻana no nā pā lithium-ion mai 80% a 95%.'O ia ho'i, pono 'oe e waiho i ka li'ili'i loa o ka 5% a i ka 20% ka uku (e like 'ole ka pākēneka ma muli o ka pila kiko'ī) i loko o ka pila.ʻO ka hohonu o ka hoʻokuʻu ʻana o nā pā lithium hao phosphate (LiFeP04) he kiʻekiʻe kiʻekiʻe ma 100%.Hōʻike kēia i hiki ke hoʻokuʻu piha ʻia ka pākaukau me ka ʻole o ka pōʻino.ʻO ka pākaukau lithium iron phosphate ka mea punahele nui e pili ana i ka hohonu o ka pau ʻana.

He aha ka pōʻino nui loa o kahi pākaukau Lithium-ion?

ʻO ke kumukūʻai a me ka hilinaʻi o nā ʻōnaehana mālama ikehu, e like me nā mea i hoʻohana ʻia i nā lako mana hoʻihoʻi a i ʻole e hōʻemi i ka loli ʻana o ka mana i hana ʻia mai nā kumu ikehu hou, ua hoʻohuli nui ʻia e ke ola hana o nā pā.Eia nō naʻe, loaʻa i nā pākahi lithium-ion nā drawbacks koʻikoʻi, me nā hopena ʻelemakule a me ka pale.

ʻOi aku ka haʻahaʻa o ka ikaika o nā pā lithium-ion a me nā cell ma mua o nā pā hao phosphate Lithium.Pono lākou e makaʻala i ka hoʻolimalima ʻana a hoʻokuʻu nui ʻia.Eia hou, pono lākou e mālama i kēia manawa i loko o nā palena kūpono.ʻO ka hopena, hoʻokahi drawback o nā ʻeke lithium-ion ʻo ia ka pono e hoʻohui ʻia ka circuit circuit e mālama pono ai i loko o kā lākou mau pae hana palekana.

ʻO ka mea pōmaikaʻi, ua maʻalahi ka hoʻokomo ʻana i kēia mea i loko o ka pākaukau a i ʻole, inā ʻaʻole hiki ke hoʻololi ʻia ka pākaukau, nā mea hana.Hiki ke hoʻohana ʻia nā pākahi Li-ion me ka ʻole o ka ʻike loea ma muli o ka hoʻohui ʻia ʻana o ka circuitry hoʻokele pākaukau.Ke hoʻopiha piha ʻia ka pākaukau, hiki ke hoʻopaʻa ʻia ma luna o ka hoʻopiʻi, a e ʻoki ka charger i ka mana o ka pā.

Ua hoʻokumu ʻia nā ʻōnaehana hoʻokele pākaukau lithium-ion e nānā i nā ʻano like ʻole o kā lākou hana.Hoʻopaʻa ke kaapuni pale i ka volta kiʻekiʻe loa o kēlā me kēia kelepona i ka wā e hoʻopiʻi ana no ka mea hiki ke hoʻopōʻino i ka nui o ka uila.No ka mea, hoʻokahi wale nō pili o nā pila, hoʻopiʻi pinepine ʻia lākou i ka pūʻulu, e hoʻonui ana i ka pilikia o ka loaʻa ʻana o kahi kelepona i kahi voli kiʻekiʻe aʻe ma mua o ka pono no ka mea pono nā cell like ʻole i nā pae uku like ʻole.

Mālama pū ka ʻōnaehana hoʻokele pila i ka wela o ke kelepona e pale aku i nā wela kiʻekiʻe.Loaʻa i ka hapa nui o nā pākaukau ka palena palena ʻoi loa ma waena o 1°C a me 2°C.Eia nō naʻe, i ka wā e hoʻopaʻa wikiwiki ai, loaʻa iki kekahi i kekahi manawa.

ʻO ka ʻoiaʻiʻo o ka emi ʻana o nā pākahi lithium ion i ka manawa ʻo ia kekahi o nā drawbacks nui o ka hoʻohana ʻana iā lākou i nā mea kūʻai aku.Pili kēia i ka manawa a i ʻole ka kalena, akā pili pū nō hoʻi i ka nui o nā pōʻai hoʻokuʻu i hoʻoiho ʻia i ka pākaukau.ʻO ka manawa pinepine, hiki i nā pila ke hoʻomanawanui i ka 500 a i ka 1000 mau kaʻina hoʻokuʻu hoʻoiho ma mua o ka hoʻomaka ʻana o ko lākou hiki ke emi.Ke piʻi nei kēia helu i ka holomua ʻana o ka ʻenehana lithium-ion, akā inā i kūkulu ʻia nā pila i loko o ka mīkini, pono paha e hoʻololi ʻia ma hope o kekahi manawa.

Pehea e koho ai ma waena o LiFePO4 a me Lithium-Ion?

Lithium hao phosphate (LiFePO4) he nui nā pōmaikaʻi o nā pila i ka hoʻohālikelike ʻia me nā pā lithium-ion.ʻOi aku ka maikaʻi o ka hoʻokuʻu ʻana a me ka hoʻopiʻi, ʻoi aku ka lōʻihi o ke ola, ʻaʻohe mālama, palekana loa, a me ka māmā, e haʻi i kekahi.ʻOiai ʻaʻole ʻo LiFePO4 i waena o nā mea kūʻai aku ma ka mākeke, ʻo ia ka waiwai nui o ka wā lōʻihi ma muli o ko lākou ola lōʻihi a me ka mālama ʻole.

Ma kahi 80 pakeneka hohonu o ka hoʻokuʻu ʻana, hiki ke hoʻihoʻi ʻia nā pākahi lithium hao phosphate a hiki i 5000 mau manawa me ka ʻole o ka hoʻokō ʻana i ka pono.Hiki ke hoʻonui ʻia ke ola hana o nā pākahi lithium hao phosphate (LiFePO4).

Eia kekahi, ʻaʻohe hopena hoʻomanaʻo o nā pākaukau, a hiki iā ʻoe ke mālama iā lākou no ka manawa lōʻihi ma muli o ko lākou haʻahaʻa haʻahaʻa haʻahaʻa (3% mahina).Pono ka mālama kūikawā no nā ʻōhua lithium-ion.Inā ʻaʻole, e hoʻemi hou ʻia ko lākou ola.

Hiki ke hoʻohana ʻia he 100% ka nui o ka hoʻopiʻi ʻana o nā pākahi lithium hao phosphate (LiFePO4).He kūpono hoʻi lākou no nā noi like ʻole ma muli o kā lākou uku wikiwiki a me nā uku hoʻokuʻu.Hoʻonui ʻia ka maikaʻi, a hoʻemi ʻia kekahi lohi e ka hoʻopiʻi wikiwiki.Hāʻawi ʻia ka mana i nā ʻāwīwī wikiwiki e nā au pulse hoʻokuʻu kiʻekiʻe.

Hoʻoholo

Ua hoʻomau ka uila o ka lā ma ka mākeke no ka mea ʻoi aku ka maikaʻi o nā pihi.He palekana ka ʻōlelo ʻana ʻo kahi ʻoi aku ka maikaʻi o ka mālama ʻana i ka ikehu e alakaʻi wale i kahi ʻoi aku ka maʻemaʻe, palekana, a me ka waiwai.Hiki i nā mea mana o ka lā ke pōmaikaʻi nui mai ka hoʻohana ʻana i ka lithium iron phosphate a me nā pā lithium-ion.

Eia naʻe,LiFePO4ʻoi aku ka maikaʻi o nā pila no nā mea kūʻai aku a me nā mea kūʻai aku.He koho maikaʻi loa ka hoʻokomo ʻana i nā kikowaena uila paʻa me nā pākahi LiFePO4 ma muli o kā lākou hana ʻoi aku ka maikaʻi, ka lōʻihi o ke ola ʻana, a me ka hōʻemi ʻana i nā hopena kaiapuni.
