ʻO ka pākaukau Lithium-ion a i ʻole NiMH ʻoi aku ka maikaʻi o ke ola?

ʻO ka ʻokoʻa ma waena o nā pākahi lithium-ion a me nā ʻeke nickel-metal hydride penei:

Hoʻohana nui ʻia nā pākahi nickel metal hydride a me nā pā lithium-ion i ka mākeke. ʻO lākou nā ʻenekona pollution-free a me ke kaiapuni a he kahua koʻikoʻi o ka hoʻomohala ʻana i ka ikehu hou.

ʻO wai ka mea ʻoi aku ka maikaʻi, nickel metal hydride battery a i ʻole pākahi lithium ion?

ʻO ka ʻokoʻa ma waena o ka pākaukau lithium ion a me ka nickel metal hydride pākahi Ma ke ʻano, ʻo ka electrode maikaʻi o ka pākaukau Ni MH ʻo Ni (OH), ʻo ka electrode maikaʻi ʻole he hydride metala, a ʻo ka electrolyte ʻo 6mol/L potassium hydroxide solution. Hoʻohui ʻia ʻo Lixo2 + me ka lithium ion a me ka graphite ion e hana i ka lixo2, aʻo ka lixo4 + i hui pū ʻia me ka lithium ion a me ka ethylene carbonate e lilo i lixo2 + ma ke ʻano he cathode o ka pā.

Ma muli o kāna ʻenehana makua a me ka palekana maikaʻi, ʻo Ni MH pākaukau he koho koʻikoʻi no ka pā uila uila hybrid (HEV), akā paʻakikī ke hoʻokō i ke koi o ke kiʻekiʻe o ka electrification; I kēia manawa, hana nui ka pākaukau lithium Ni MH. ʻO ke kumu koʻikoʻi, ʻo ka ikehu pākaukau o ka kaʻa uila hybrid i kēia manawa he 1-2kwh wale nō, ʻaʻole hiki ke hoʻohana ʻia i ka uila a i ʻole ke ola pākaukau o ke kaʻa uila maʻemaʻe ma lalo o 3km.

I ka wā lōʻihi, ʻaʻole hiki ke hoʻohana ʻia ka NiMH iā PHEV a me ev. ʻO ka mea nui no ka hiki ʻole o ka ikehu kikoʻī a me ka ikehu o ka nickel hydrogen i nā koi o PHEV a me ev; ʻOi aku ka kiʻekiʻe o ke kumukūʻai o nā mea maka Ni (OH), a ʻoi aku ka kiʻekiʻe o ke kumukūʻai o ka hana ʻana i nā ʻenekini kiʻekiʻe; ʻO ka hoʻomohala ʻana o ka ʻenehana ʻenehana Ni MH he ʻoi loa, a ʻo ka wahi no ka hoʻomaikaʻi ʻana i ka hana pākaukau a me ka hoʻemi ʻana i ke kumukūʻai he palena loa. Loaʻa ka hopena hoʻomanaʻo like ʻo Ni MH me ka pākaukau Ni Cd, akā ʻoi aku ka liʻiliʻi ma mua o ka pila Ni Cd. No laila, ʻaʻole pono e hoʻokuʻu i kēlā me kēia manawa āu e hoʻopaʻa ai (no ka hana kūpono ʻole e hōʻino i ka pākaukau). Pono ʻoe e hoʻopiha piha a hoʻokuʻu i hoʻokahi manawa i kēlā me kēia ʻekolu mahina e hōʻoluʻolu i ka hopena hoʻomanaʻo.

25 ~ 35% (mahina) no ka pākahiko Ni MH a me 2 ~ 5% (mahina) no ka pākahiko lithium ion. He kiʻekiʻe ke kiʻekiʻe o ka hoʻokuʻu ʻana iā Ni MH pākahi, ʻoiai ʻo ka haʻahaʻa haʻahaʻa o ka pā lithium-ion.

I kēia manawa, hiki i ka nui o ka pākaukau Ni MH ke hiki i 2900mah (MAH hola, i ʻike nui ʻia ma ka ʻāina ʻo Kina ʻo R MAH). Ma hope o ka hoʻohana ʻole ʻana i ka wā lōʻihi, e kahe iki ka wai corrosive a me ka ʻino (e pōʻino i ke kino kanaka a i ʻole e hōʻino i ka hāmeʻa me ka hoʻohana ʻana i ka pākaukau), a loaʻa i ka pākaukau lithium-ion ka manawa e puhi a pahū inā ʻaʻole kūpono no ka hoʻohana. ʻO ka ʻōlelo pili, ʻo Ni MH ka pākaukau ka palekana loa.

He 1.2 V ka volta o ka pilahi Ni MH a he 3.7 V ka mea o ka paila lithium. He haʻahaʻa haʻahaʻa hoʻohaumia kaiapuni ʻo Ni MH, ʻo ka hapa nui o ke kinoea hoʻoheheʻe acid-base, a ʻoi aku ka nui

Ke hoʻohālikelike ʻia me ka pākaukau Ni MH, loaʻa i ka pākaukau lithium ion nā pono penei:

1. Kiʻekiʻe kiko'ī ikehu a me ka ikehu ikehu, e pili ana i ka pālua o ka Ni MH pākaukau, hiki ke hoʻomaikaʻi nui i ka hiki ke hoʻomanawanui, ka mana kiʻekiʻe, ka haʻahaʻa haʻahaʻa iho a ʻaʻohe hopena hoʻomanaʻo o nā kaʻa uila. Hiki i kēia mau hiʻohiʻona ke hoʻomaikaʻi i ka maʻalahi o nā kaʻa uila;

2. ʻO ke kumukūʻai haʻahaʻa a me ke kumukūʻai o nā mea maka;

3. Nui ka lumi no ka hoʻomaikaʻi ʻana i ka ʻenehana a me ka hoʻemi ʻana i ke kumukūʻai.

4. Volume: hoʻohana nui ʻia ka pākaukau lithium-ion rechargeable i nā polokalamu kelepona hou no ka mea aia nā mea maikaʻi o ka leo liʻiliʻi (like), māmā ke kaumaha, haʻahaʻa haʻahaʻa haʻahaʻa a ʻaʻohe hopena hoʻomanaʻo i hoʻohālikelike ʻia me ka nickel cadmium / nickel hydrogen battery. Ua hoʻololi mālie ʻia nā pā o nā kelepona paʻa lima, nā kamepiula, nā PDA a me nā polokalamu kelepona ʻē aʻe a mākou e hoʻohana pinepine ai e nā pā lithium-ion.

ʻAʻole maopopo loa ka hopena hoʻomanaʻo o ka pākaukau Ni MH, liʻiliʻi. I ka wā e pono ai, ʻaʻole pono e hoʻihoʻi hou ma hope o ka hoʻokuʻu ʻana i ke kukui. ʻOi aku ka maikaʻi o ka recharge ma hope o ka hoʻokuʻu ʻana i ke kukui i ka hoʻohana maʻamau.

5. Ka mana: nui ka ikehu a me ka puliki liʻiliʻi lithium ion; ʻO ka volta o ka pākahi lithium-ion hoʻokahi he ʻekolu manawa ma mua o ka pila Ni MH; Me ka ʻole o ka hopena hoʻomanaʻo, hiki ke hoʻohana a hoʻopaʻa ʻia i kēlā me kēia manawa. ʻAʻole hiki ke hoʻopaʻa ʻia i ka manawa hoʻokahi. Ma kēia ala, ʻoi aku ka nui o nā manawa o ka hoʻouka ʻana a me ka hoʻokuʻu ʻana e hoʻopilikia i ke ola lawelawe o ka pākaukau. ʻAʻole pono e mālama ʻia nā ʻona lithium ion no ka manawa lōʻihi, a e nalowale kekahi hapa o ko lākou hiki ke nalowale mau loa ma hope o ka manawa lōʻihi. ʻOi aku ka maikaʻi o ka mālama ʻana i loko o ka friji ma hope o ka hoʻouka ʻana iā 40%.

6. ʻO ke ʻano o ka hoʻouka ʻana: ʻokoʻa nā koi o ka hoʻouka ʻana o ka pā lithium-ion mai ka nickel cadmium / nickel hydrogen battery. ʻO ka volta hoʻokahi o ka pākaukau lithium-ion hiki ke hoʻihoʻi ʻia ʻo 3.6 V (hiki i kekahi mau poloka pākahi ke loaʻa i kahi pākahi lithium nominal). Hoʻohana maʻamau ʻia ke ʻano o ka volta a me ka palena o kēia manawa no ka hoʻouka ʻana o ka pā lithium-ion. Inā makemake kekahi hoaaloha e hoʻopaʻa kūʻokoʻa i ka pā lithium-ion, pono e hoʻomaopopo ʻia he ʻokoʻa ke ʻano o ka hoʻouka ʻana mai ke ʻano o ka hoʻopaʻa ʻana i kēia manawa i hoʻohana ʻia e ka nickel cadmium/nickel hydrogen battery, a ʻaʻole hiki ke hoʻohana ʻia ka charger o ka nickel cadmium/nickel hydrogen battery. ʻOiai he ʻokoʻa nā pihi Ni MH a me nā pā lithium-ion, ʻo lākou nā puʻupuʻu ikehu i ke au hou a ua pāʻani i kahi hana hiki ʻole ke hoʻololi i ka holomua o ke ola kanaka!

Wahi a ka loiloi pahuhopu, i ka wā e lilo ai ke kaumaha i kumu nui e pili ana i ka hana o ka huahana a hiki ke hoʻokō ʻia ka mālama ʻana i ka pākaukau i ka manawa, ʻo ka pā lithium-ion kahi ala kūlohelohe. Ke koi ʻia ka mana kiʻekiʻe, ka palekana maikaʻi, ka hilinaʻi kiʻekiʻe a me ka hoʻokele waiwai, e ʻoi aku ka maikaʻi o ka pila NiMH.
