He aha nā Bateri Lithium Ion

ʻO nā ʻōhua Lithium-ion kahi ʻano kaulana o ka kemika pākaukau. ʻO kahi pōmaikaʻi nui i hāʻawi ʻia e kēia mau pākaukau ʻo ia ka mea hiki ke hoʻouka hou. Ma muli o kēia hiʻohiʻona, loaʻa lākou i ka hapa nui o nā mea kūʻai aku i kēia lā e hoʻohana ana i kahi pākaukau. Hiki ke loaʻa iā lākou ma nā kelepona, nā kaʻa uila, a me nā kaʻa kolepa uila.

Pehea ka hana ʻana o nā Bateri Lithium-Ion?

Hana ʻia nā pākahi Lithium-ion i hoʻokahi a i ʻole nā pūnaewele lithium-ion. Loaʻa iā lākou kahi papa kaapuni pale e pale aku ai i ka overcharging. Ua kapa ʻia nā kelepona he mau pākahi i hoʻokomo ʻia i loko o kahi pahu me kahi papa kaapuni pale.

Ua like anei na Bateri Lithium-Ion me na Bateri Lithium?

ʻAʻole. He ʻokoʻa loa ka pākaukau lithium a me ka pā lithium-ion. ʻO ka ʻokoʻa nui ʻo ia ka mea hiki ke hoʻouka hou ʻia. ʻO kahi ʻokoʻa nui ʻē aʻe ke ola o ka mālama. Hiki ke hoʻohana ʻole ʻia kahi pākahi lithium a hiki i 12 mau makahiki, ʻoiai ʻo nā pā lithium-ion ke ola ʻana a hiki i 3 mau makahiki.

He aha nā ʻāpana koʻikoʻi o nā Bateri Lithium Ion

ʻEhā mau ʻāpana nui o nā cell lithium-ion. ʻO kēia nā:

Anode

Hiki i ka anode ke neʻe i ka uila mai ka pākaukau i kahi kaapuni waho. Mālama pū ʻo ia i nā ion lithium i ka wā e hoʻopiʻi ana i ka pākaukau.

Cathode

ʻO ka cathode ka mea e hoʻoholo ai i ka hiki a me ka volta o ke kelepona. Hoʻopuka ia i nā ion lithium i ka wā e hoʻokuʻu ai i ka pākaukau.

Electrolyte

ʻO ka electrolyte kahi mea, e lawelawe ana ma ke ʻano he conduit no nā ion lithium e neʻe ai ma waena o ka cathode a me ka anode. Hoʻokumu ʻia me nā paʻakai, nā mea hoʻohui, a me nā mea hoʻoheheʻe like ʻole.

ʻO ka mea hoʻokaʻawale

ʻO ka ʻāpana hope loa i loko o kahi cell lithium-ion ka mea hoʻokaʻawale. Hana ʻo ia i mea pale kino e hoʻokaʻawale i ka cathode a me ka anode.

Ke hana nei nā ʻona lithium-ion ma ka hoʻoneʻe ʻana i nā ion lithium mai ka cathode a i ka anode a me ka ʻokoʻa ma o ka electrolyte. I ka neʻe ʻana o nā ion, hoʻāla lākou i nā electrons manuahi i ka anode, e hana ana i ka uku ma ka ʻohi ʻohi kūpono. Ke holo nei kēia mau electrons ma o ka mea hana, kelepona a i ʻole kaʻa kolepa, i ka ʻohi ʻino a hoʻi i ka cathode. Kāohi ʻia ke kahe manuahi o nā electrons i loko o ka pākaukau e ka mea hoʻokaʻawale, e koi ana iā lākou i nā pilina.

Ke hoʻopiʻi ʻoe i kahi pākahi lithium-ion, e hoʻokuʻu ka cathode i nā ion lithium, a neʻe lākou i ka anode. I ka hoʻokuʻu ʻana, neʻe nā ion lithium mai ka anode a i ka cathode, kahi e hoʻopuka ai i ke kahe o kēia manawa.

I ka manawa hea i hana ʻia ai nā ʻanuʻu Lithium-Ion?

Ua hoʻokumu mua ʻia nā pākini Lithium-ion i ka makahiki 70 e ka mea loea Pelekane ʻo Stanley Whittingham. I loko o kāna mau hoʻokolohua, ua noiʻi ka poʻe ʻepekema i nā kemika like ʻole no kahi pākaukau e hiki ke hoʻopiha iā ia iho. ʻO kāna hoʻāʻo mua e pili ana i ka titanium disulfide a me ka lithium e like me nā electrodes. Eia nō naʻe, e pōʻalo a pahū nā pila.

I nā makahiki 80, ua hoʻokō kekahi kanaka ʻepekema ʻo John B. Goodenough. Ma hope koke iho, ua hoʻomaka ʻo Akira Yoshino, he loea Kepani, i ka noiʻi ʻana i ka ʻenehana. Ua hōʻoia ʻo Yoshino lāua ʻo Goodenough ʻo ka metala lithium ke kumu nui o nā pahū.

I ka makahiki 90, ua hoʻomaka ka ʻenehana lithium-ion i ka traction, e lilo koke i kumu mana kaulana i ka hopena o nā makahiki he ʻumi. Ua hōʻailona ia i ka manawa mua i kūʻai ʻia ka ʻenehana e Sony. ʻO kēlā moʻolelo palekana maikaʻi ʻole o nā pā lithium i alakaʻi i ka hoʻomohala ʻana i nā ʻeke lithium-ion.

ʻOiai hiki i nā ʻeke lithium ke hoʻopaʻa i ka nui o ka ikehu kiʻekiʻe, ʻaʻole palekana lākou i ka wā o ka hoʻouka ʻana a me ka hoʻokuʻu ʻana. Ma ka ʻaoʻao ʻē aʻe, palekana nā pā lithium-ion i ka hoʻopaʻa ʻana a me ka hoʻokuʻu ʻana i ka wā e hoʻohana ai nā mea hoʻohana i nā kulekele palekana.

He aha ka Lithium Ion Chemistry?

Nui nā ʻano o nā kemika pākaukau lithium-ion. ʻO nā mea kūʻai kūʻai:

Lithium Titanate
Lithium Nickel Cobalt Aluminum Oxide
Lithium Nickel Manganese Cobalt Oxide
Lithium Manganese Oxide (LMO)
Lithium Cobalt Oxide
Lithium Iron Phosphate (LiFePO4)

Nui nā ʻano kemika no nā pā lithium-ion. Loaʻa i kēlā me kēia me kona mau hiʻohiʻona. Eia naʻe, kūpono kekahi no nā hihia hoʻohana kikoʻī. No laila, ʻo ke ʻano āu e koho ai e hilinaʻi ʻia i kāu pono mana, kālā, palekana palekana, a me ka hihia hoʻohana kikoʻī.

Eia nō naʻe, ʻo nā pākahi LiFePO4 ke koho kūʻai nui loa. Aia i loko o kēia mau pila he graphite carbon electrode, e lawelawe ana ma ke anode, a me ka phosphate ma ka cathode. He lōʻihi ko lākou ola pōʻaiapuni a hiki i 10,000 mau pōʻaiapuni.

Hoʻohui, hāʻawi lākou i ke kūpaʻa wela nui a hiki ke mālama pono i nā piʻi pōkole i ke koi. Ua helu ʻia nā pākahi LiFePO4 no ka paepae holo wela a hiki i ka 510 degere Fahrenheit, ka mea kiʻekiʻe loa o nā ʻano pākaukau lithium-ion i kūʻai ʻia.

ʻO nā pono o nā Bateri LiFePO4

Ke hoʻohālikelike ʻia i ka waikawa alakaʻi a me nā ʻāpana lithium-based ʻē aʻe, ʻoi aku ka maikaʻi o nā pā lithium iron phosphate. Hoʻopaʻa a hoʻokuʻu maikaʻi lākou, lōʻihi ka lōʻihi, a hiki ke hohonu cycleme ka nele o ka hiki. ʻO kēia mau mea maikaʻi ʻo ia ka hāʻawi ʻana o nā pila i nā kumukūʻai nui i ko lākou ola ʻana i hoʻohālikelike ʻia i nā ʻano pākaukau ʻē aʻe. Aia ma lalo iho nā pono kiko'ī o kēia mau pila i nā kaʻa mana haʻahaʻa a me nā mea hana ʻoihana.

Bateri LiFePO4 I Na Kaa Mama Haahaa

ʻO nā kaʻa uila haʻahaʻa (LEV) he mau kaʻa huila ʻehā i emi iho ma mua o 3000 paona. Hoʻohana ʻia lākou e nā pihi uila, kahi i koho nui ʻia no nā kaʻa kolepa a me nā hoʻohana leʻaleʻa ʻē aʻe.

Ke koho ʻana i ke koho pākaukau no kāu LEV, ʻo kekahi o nā mea nui e noʻonoʻo ai ka lōʻihi. No ka laʻana, pono e lawa ka mana o nā kaʻa kolepa i hoʻohana ʻia i ka pākaukau no ka holo ʻana a puni kahi papa kolepa 18-hole me ka ʻole e hoʻomaha.

ʻO kekahi mea nui e noʻonoʻo ai ʻo ia ka papa hana mālama. ʻAʻole pono ka mālama ʻana i kahi pākaukau maikaʻi e hōʻoia i ka hauʻoli nui o kāu hana leʻaleʻa.

Hiki nō hoʻi i ka pākaukau ke hana ma nā ʻano ʻano ʻano like ʻole. No ka laʻana, pono ia e ʻae iā ʻoe e kolepa i ka wela o ke kauwela a i ka hāʻule i ka wā e hāʻule ai ka mahana.

Pono pū kekahi pākaukau maikaʻi me kahi ʻōnaehana hoʻomalu e hōʻoiaʻiʻo ʻaʻole ia e wela a ʻoluʻolu paha, e hoʻohaʻahaʻa i kona hiki.

ʻO kekahi o nā hōʻailona maikaʻi loa e kū nei i kēia mau kūlana kumu akā koʻikoʻi ʻo ROYPOW. Ua helu ʻia kā lākou laina o nā pā lithium LiFePO4 no nā mahana o 4°F a 131°F. Hele mai nā pila me kahi ʻōnaehana hoʻokele pākaukau i kūkulu ʻia a maʻalahi loa e hoʻokomo.

Noi Hana no na Bateri Lithium Ion

ʻO nā pahu lithium-ion kahi koho kaulana i nā noi ʻoihana. ʻO ka kemika maʻamau i hoʻohana ʻia ʻo ia nā ʻeke LiFePO4. ʻO kekahi o nā mea hana maʻamau e hoʻohana ai i kēia mau pila:

Narrow aisle forklifts
Nā forklift counterbalanced
3 Huila Forklifts
Nā mea hele wāwae
Hoʻopau a me nā mea holo waena

Nui nā kumu e ulu nui ai nā pākahi lithium ion ma nā ʻoihana ʻoihana. ʻO nā mea nui:

Kiʻekiʻe a me ka lōʻihi

ʻOi aku ka nui o ka ikehu a me ka lōʻihi o ka lōʻihi o nā ʻona Lithium-ion i hoʻohālikelike ʻia me nā pākika lead-acid. Hiki iā lākou ke kaumaha i ka hapakolu o ke kaumaha a hāʻawi i ka huahana like.

ʻO ko lākou pōʻaiapili ola kekahi pono nui. No ka hana ʻoihana, ʻo ka pahuhopu ka mālama ʻana i nā kumukūʻai hoʻihoʻi pōkole i ka liʻiliʻi. Me nā pākahi lithium-ion, hiki ke hoʻopaʻa ʻia nā pākahi forklift i ʻekolu manawa ka lōʻihi, e alakaʻi ana i ka mālama kālā nui i ka holo lōʻihi.

Hiki iā lākou ke hana ma kahi hohonu o ka hoʻokuʻu ʻana a hiki i 80% me ka ʻole o ka hopena i ko lākou hiki. He mea ʻē aʻe kēlā i ka mālama manawa. ʻAʻole pono nā hana e hoʻōki i waena o ka hoʻololi ʻana i nā pihi, hiki ke alakaʻi i nā tausani o nā hola kanaka i mālama ʻia i kahi manawa nui.

Kiekie-Spede Charging

Me nā ʻāpana ʻenehana lead-acid, ʻo ka manawa maʻamau ma kahi o ʻewalu hola. Ua like ia me kahi hoʻololi holoʻokoʻa 8-hola kahi i loaʻa ʻole ai ka pākaukau no ka hoʻohana. No laila, pono ka luna mana e helu i kēia manawa hoʻomaha a kūʻai aku i nā ʻokoʻa ʻē aʻe.

Me nā pākahi LiFePO4, ʻaʻole ia he paʻakikī. ʻO kahi laʻana maikaʻi kaʻO ROYPOW ʻenehana LifePO4 lithium pākaukau, ka mea e hoʻopaʻa ai i ʻehā mau manawa ʻoi aku ka wikiwiki ma mua o nā pihi waika lead. ʻO kekahi pōmaikaʻi ʻē aʻe ka hiki ke hoʻomau i ka maikaʻi i ka wā o ka hoʻokuʻu ʻana. Loaʻa pinepine ka lohi o ka hana ʻana i nā ʻakika ʻakika alakaʻi i ko lākou hoʻokuʻu ʻana.

ʻAʻohe pilikia o ka hoʻomanaʻo ʻana i ka laina ROYPOW o nā pila ʻoihana, mahalo i kahi ʻōnaehana hoʻokele pono. Hoʻopilikia pinepine ʻia nā ʻakika ʻakika alakaʻi i kēia pilikia, hiki ke alakaʻi i ka hiki ʻole ke hōʻea i ka mana piha.

Me ka manawa, hoʻoulu ia i ka sulfatation, hiki ke ʻoki i ko lākou ola pōkole i ka hapalua. Hoʻopuka pinepine ʻia ka pilikia ke mālama ʻia nā pihi wai kepau me ka ʻole o ka uku piha. Hiki ke hoʻopaʻa ʻia nā ʻona lithium i nā manawa pōkole a mālama ʻia ma kēlā me kēia mana ma luna o ka zero me ka pilikia ʻole.

Palekana a me ka lawelawe ʻana

Loaʻa ka pōmaikaʻi nui o nā pākahi LiFePO4 i nā ʻoihana ʻoihana. ʻO ka mea mua, loaʻa iā lākou ke kūpaʻa wela nui. Hiki i kēia mau pila ke hana i nā mahana a hiki i 131 ° F me ka ʻole o ka pōʻino. E nalowale ana nā ʻakika ʻakika alakaʻi a hiki i ka 80% o ko lākou pōʻai ola ma kahi mahana like.

ʻO kekahi pilikia ke kaumaha o nā pila. No ka mana like o ka pākaukau, ʻoi aku ka nui o ke kaumaha o nā ʻakika acid lead. No laila, makemake pinepine lākou i nā lako kikoʻī a me ka manawa hoʻonohonoho lōʻihi, hiki ke alakaʻi i ka liʻiliʻi o nā hola kanaka i hoʻohana ʻia ma ka hana.

ʻO kekahi pilikia ka palekana o ka limahana. Ma keʻano laulā, ʻoi aku ka palekana o nā ʻokoʻa LiFePO4 ma mua o nā pākī lead-acid. E like me nā alakaʻi o ka OSHA, pono e mālama ʻia nā pākī waikawa lead i loko o kahi lumi kūikawā me nā mea hana i hoʻolālā ʻia e hoʻopau i nā uahi ʻino. Hoʻokomo ia i kahi kumukūʻai hou a paʻakikī i kahi hana ʻoihana.

Ka hopena

Loaʻa ka pōmaikaʻi o nā pākahi Lithium-ion i nā ʻoihana ʻenehana a no nā kaʻa uila haʻahaʻa. ʻOi aku ka lōʻihi o lākou, no laila e mālama i ke kālā o nā mea hoʻohana. ʻO kēia mau pila ka mālama ʻole ʻia, he mea koʻikoʻi loa ia i kahi ʻoihana ʻoihana kahi mea nui e mālama ai i ke kumukūʻai.
