ʻOkoʻa ma waena o nā pākahiko Lithium a me nā pākahiko NiMH
He mea koʻikoʻi nā pila i loko o nā mea uila he nui a mākou e hoʻohana ai i kēlā me kēia lā, mai nā kelepona paʻalima a me nā kamepiula lawe lima a hiki i nā kaʻa uila. ʻElua ʻano pila maʻamau, ʻo ia ka lithium a me nā pila nickel-metal hydride (NiMH). ʻOiai ʻo lāua ʻelua e lawelawe nei ma ke ʻano he waihona ikehu, he ʻano like ʻole ko lāua, nā pono, a me nā hemahema. E nānā kēia ʻatikala i nā ʻokoʻa koʻikoʻi ma waena o nā pila lithium a me NiMH, e hōʻike ana i nā ʻano e like me ka hiki, ke kaumaha, ke ola, ke kumukūʻai, a me nā noi.
ʻO ka haku mele ʻana a me ke kumumanaʻo hana
Pākahiko Lithium
Hoʻohana nā pila Lithium i ka lithium ma ke ʻano he mea electrode mua. ʻO nā ʻano i ʻike nui ʻia ʻo ia nā pila lithium-ion (Li-ion) a me lithium-polymer (Li-Po). I loko o nā pila Li-ion, neʻe nā ion lithium mai ka electrode maikaʻi ʻole (anode) i ka electrode maikaʻi (cathode) ma o ka electrolyte i ka wā hoʻokuʻu ʻana, a ʻo ka hope i ka wā e hoʻouka hou ana.
Pākahi NiMH
Hoʻohana nā pila NiMH i ka nickel hydroxide ma ke ʻano he cathode a me kahi metala hui ma ke ʻano he anode. ʻO ka mea nui i ka hopena kemika i loko o nā pila NiMH he mau iona hydrogen (H+), e hiki ai iā lākou ke mālama a hoʻokuʻu i ka ikehu.
Ka Mana Ikehu a me ka Density
Pākahiko Lithium
Ua ʻike ʻia nā pila Lithium no ko lākou nui o ka ikehu. ʻO ka maʻamau, he 150-200 watt-hola no ke kilokani (Wh/kg) ka nui o ka ikehu o nā pila Li-ion. ʻO ke ʻano kēia, hiki i nā pila lithium ke mālama i ka ikehu hou aʻe no kēlā me kēia anakahi kaumaha ma mua o nā pila NiMH. ʻO kēia nui o ka ikehu e hoʻolilo i nā pila lithium i koho kūpono no nā mea hana e pono ai ka mana kiʻekiʻe i ka nui liʻiliʻi, e like me nā kelepona akamai a me nā kamepiula lawe lima.
Pākahi NiMH
ʻO ka nui o ka ikehu o nā pila NiMH ma kahi o 60-120 Wh/kg, ʻoi aku ka haʻahaʻa ma mua o nā pila lithium. ʻOiai kēia haʻahaʻa o ka ikehu, loaʻa i nā pila NiMH ka pono o ka hiki ke kū i nā pōʻaiapuni hoʻouka a hoʻokuʻu hou aku ma mua o nā pila lithium—kahi ʻano a mākou e kūkākūkā hou aku ai ma hope.
Kaumaha a me ka nui
No ka mea, ʻoi aku ka nui o ka ikehu o nā pila lithium, ʻoi aku ka māmā a me ka liʻiliʻi ma mua o nā pila NiMH o ka mana like. He pōmaikaʻi koʻikoʻi kēia no nā mea lawe lima e pono ai ka nui a me ke kaumaha liʻiliʻi. No ka laʻana, i loko o ke ʻano o nā kaʻa uila, hiki i ka hoʻohana ʻana i nā pila lithium ke hōʻemi i ke kaumaha holoʻokoʻa o ke kaʻa, kahi e hoʻonui ai i ka pono a me ka laulā.
Ke ola a me nā pōʻaiapuni hoʻouka
Pākahiko Lithium
ʻOi aku ka pōkole o ke ola o nā pila Lithium ma mua o nā pila NiMH, me ka helu o nā pōʻaiapuni hoʻouka ʻana mai 300 a 500. Eia nō naʻe, pili kēia i nā mea e like me ka mahana hana a me ke ʻano o ka mālama ʻana i ka pila. Loaʻa i nā pila Lithium kahi hanana i ʻike ʻia ʻo "thermal runaway," kahi e hiki ai i ka pila ke wela loa a hiki ke hoʻoulu i ke ahi inā ʻaʻole mālama pono ʻia.
Pākahi NiMH
I kēia manawa, ʻoi aku ka maikaʻi o ke ola o nā pila NiMH i ka hoʻouka ʻana, e hōʻea pinepine ana i 500 a 1000 mau pōʻaiapuni a ʻoi aku paha. ʻOi aku ka paʻa o nā pila NiMH i ka hoʻokuʻu koke ʻana a me nā mahana kiʻekiʻe. Eia nō naʻe, hiki ke loaʻa kahi kūlana i ʻike ʻia ʻo ka "hopena hoʻomanaʻo", kahi e emi ai ka mana o ka pila inā ʻaʻole i hoʻouka ʻia a hoʻohana ʻia ma kekahi ʻano. ʻOi aku ka maʻalahi o kēia me nā pila NiMH ma mua o nā pila lithium.
Ka Pono o ka Hoʻouka ʻana a me ka Māmā
Pākahiko Lithium
ʻOi aku ka maikaʻi o nā pila lithium ma ke ʻano o ka manawa hoʻouka. Ma muli o ka ʻenehana a me nā kikoʻī, hiki ke hoʻouka ʻia nā pila lithium he nui i 80% ka mana ma lalo o hoʻokahi hola me kahi mea hoʻouka wikiwiki. ʻO kēia hiki ke hoʻolilo i nā pila lithium i mea kūpono loa no nā noi e pono ai ka hoʻouka wikiwiki, e like me nā kelepona akamai a me nā polokalamu lawe lima ʻē aʻe.
Pākahi NiMH
ʻO ka maʻamau, pono nā pākahiko NiMH i nā manawa hoʻouka lōʻihi. Hiki i ka hoʻouka piha ʻana ke hala i kekahi mau hola, ma muli o ka hiki a me ke ʻano o ka mea hoʻoili i hoʻohana ʻia. Eia nō naʻe, ʻoi aku ka palekana o ka hoʻouka ʻana o nā pākahiko NiMH ma lalo o nā ʻano kūlana like ʻole, ʻoiai i nā kūlana hoʻouka wikiwiki.
Kumukuai a me ka Loaʻa
Pākahiko Lithium
ʻOi aku ke kumukūʻai o nā pila Lithium ma mua o nā pila NiMH, ma muli o ke kumukūʻai kiʻekiʻe o nā mea hana a me ka ʻenehana hana paʻakikī. Eia nō naʻe, ma muli o ke koi nui no nā pila lithium i nā noi ʻenehana holomua like ʻole, ua emi nui ke kumukūʻai o nā pila lithium i nā makahiki i hala iho nei.
Pākahi NiMH
ʻOi aku ka liʻiliʻi o ke kumukūʻai o nā pila NiMH ma mua o nā pila lithium. ʻOi aku ka maikaʻi o ke kumukūʻai o nā pila no kekahi mau hana, e like me nā mea pāʻani a nā keiki, kekahi mau mea uila o ka hale, a me nā mea hana ʻē aʻe ʻaʻole pono ka nui o ka ikehu.
Palekana a me ke Kaiapuni
Pākahiko Lithium
He mea nui ka palekana i ka wā e hoʻohana ai i nā pila lithium. ʻOiai he mea kakaikahi, aia kekahi mau hihia i pahū ai a puhi ʻia paha nā pila lithium inā ʻaʻole mālama pono ʻia a hoʻopiha ʻia paha. ʻO ke kumu nui o kēia ma muli o ka hanana o ka holo ʻana o ka wela. No laila, ʻo nā mea hana e hoʻohana ana i nā pila lithium ua lako pinepine ʻia me nā ʻano hana palekana like ʻole.
No ke kaiapuni, aia nā kemika i loko o nā pākahiko lithium e pono ai ka lawelawe kūikawā i ka wā e hana hou ʻia ai. Ua manaʻo ʻia hoʻi ʻo Lithium he kumuwaiwai palena ʻoi aku ma mua o nā mea i hoʻohana ʻia i loko o nā pākahiko NiMH.
Pākahi NiMH
ʻOi aku ka palekana o nā pila NiMH ma mua o nā pila lithium ma muli o ko lākou emi ʻana o ka pilikia o ke ahi a i ʻole ka pahū. Eia kekahi, ʻoi aku ka maʻalahi o ka hana hou ʻana i nā pila NiMH no ka mea ʻoi aku ka liʻiliʻi o ka ʻawahia o kā lākou mau mea ma mua o nā pila lithium.
Ka hoʻohana
Pākahiko Lithium
Hoʻohana nui ʻia nā pila lithium i nā mea hana e pono ai ka hana kiʻekiʻe a me ka nui liʻiliʻi, e like me nā kelepona akamai, nā kamepiula lawe lima, a me nā papa. He koho mua nō hoʻi lākou no nā kaʻa uila a me nā mea uila lawe lima ʻē aʻe.
Pākahi NiMH
Hoʻohana nui ʻia nā pila NiMH i nā noi e pono ai nā pōʻaiapuni hoʻouka a hoʻokuʻu he nui a kahi e lilo ai ka hana kumukūʻai i mea koʻikoʻi. ʻO kēia mau mea e komo pū me nā lako hale, nā mea pāʻani a nā keiki, a me kekahi mau ʻano kaʻa hybrid.
Ka hopena
Loaʻa i nā ʻano pākahiko ʻelua, ʻo ka lithium a me ka NiMH, ko lākou mau pono a me nā hemahema ma muli o nā pono noi kikoʻī. Hāʻawi nā pākahiko Lithium i ka nui o ka ikehu, nā wikiwiki hoʻouka wikiwiki, a me ke kaumaha māmā, e kūpono ai no nā polokalamu lawe lima a me nā kaʻa uila. Ma ka ʻaoʻao ʻē aʻe, hāʻawi nā pākahiko NiMH i ke ola pōʻaiapuni maikaʻi aʻe, ke kumukūʻai haʻahaʻa, a me ke kūpaʻa nui aʻe ma lalo o kekahi mau kūlana, e lilo ana lākou i koho waiwai no nā ʻano hana like ʻole o kēlā me kēia lā.
ʻO ke koho ma waena o nā pila lithium a me NiMH e kau ʻia ma luna o nā koi mana, ka waihona kālā, a me nā hopohopo palekana o kahi noi kikoʻī. Ma ka hoʻomaopopo ʻana i kēia mau ʻokoʻa, hiki i nā mea kūʻai aku a me nā ʻenekinia ke hana i nā hoʻoholo naʻauao e pili ana i ke ʻano o ka pila e kūpono loa i kā lākou mau pono.
