LiFePO4 pākaukau - ʻO ke kahawai kahawai nui no ke kukui lā

Me ka ʻoi aku o nā ʻoihana waiwai nui o ka honua e neʻe nui ana i nā pahuhopu neutrality carbon honua a puni ka waena o ke kenekulia, ke ʻike nei mākou i nā ʻano piʻi i nā koi o ke alanui o ka lā a me nā kukui kahe e like me ka hopena kūpono e hoʻomālamalama i nā waiwai pilikino, alanui a me nā wahi ākea me nā kukui LED kūpono.

ʻO nā ʻanuʻu rechargeable kekahi o nā mea nui loa no ka hilinaʻi o ka kukui lā. Ua ʻike mākou a pau he mea nui ka hoʻonohonoho ʻana o ka panel solar no ka hoʻokō ʻana i ka ʻōnaehana solar. He mea koʻikoʻi kēia, akā ʻo kona pono e hilinaʻi ʻia i ka maikaʻi o nā pihi ma ka ʻōnaehana solar. ʻO ke ʻano a me ke ʻano o nā pila e hoʻoholo ai i ka lōʻihi o nā panela solar o ka nui like e pono ai ka lā. ʻEhā mau hola wale nō o ka lā e pono ai i kekahi mau pila a hiki ke hoʻomālamalama i ka pō holoʻokoʻa. Pono paha kekahi i ka lā piha o ka lā.

Ma kēia ʻatikala e nānā mākou i nā ʻano pākaukau rechargeable no ke kukui lā. He aha ia mau mea, a me nā pono a me nā pōʻino o kēia mau pila e kōkua iā ʻoe e hoʻomaopopo i ka maikaʻi a me ka pōʻino o kēia mau pā.

ʻO Ni-Cd, Ni-MH, a me Lithium-ion nā ʻano ʻano nui ʻekolu o nā pākaukau rechargeable i hoʻohana ʻia i kēia manawa.

Ni-Cd, nickel-cadmium. Aia ia me ka nickel a me ka cadmium, ka mea hoʻokaʻawale a me ka alkaline. ʻO kēia ka mea kaulana loa e hoʻihoʻi hou ʻia i nā ʻōhua no nā polokalamu kelepona i ka makahiki 1990, akā ke hoʻopau ʻia nei ia no ka mea aia ka cadmium metala kaumaha e hoʻopōʻino i ke kaiapuni. ʻAʻole mākou e wehewehe i kēia ʻatikala.

Ua like loa ka pila Ni-MH me ka Nickel cadmium battery akā aia i loko o Nickel hydroxide e like me nā electrodes maikaʻi, Hydrogen absorbing alloys (nā loulou) e like me nā electrodes maikaʻi ʻole a me ka electrolyte alkaline potassium hydroxide. He 1.2V ka uila uila o ka pila Ni-MH a he 1.6V ka hoʻouka ʻana i kēlā me kēia kelepona. Me kēia haʻahaʻa haʻahaʻa haʻahaʻa i kēlā me kēia kelepona, pono nā mea hana e hoʻohui i nā cell he nui e kūkulu i nā ʻeke pākaukau e hoʻonui ai i kā lākou volta e hana ʻole i ka nui a ʻaʻole kūpono ke kumu kūʻai. ʻO ka hemahema o ka pākaukau Ni-MH ʻo ia kona kiʻekiʻe kiʻekiʻe. Inā haʻalele ʻoe i kahi pilahi Ni-MH i hoʻopiha piha ʻia no kekahi mau mahina e nalowale ana ka hapa nui o kāna uku. Hiki ke lilo i ka pilahi Ni-MH ma'amau mai ka 4-20% o kona uku i ka lā mua a ma hope iho e hā'ule ana ka nui o ka ho'oku'u 'ana iā ia iho ma kahi o 1% o kēlā me kēia lā ma muli o ke ana wela.

Lithium Battery no nā kukui alanui Solar e lilo ana i mea hoʻonā kahawai nui. Ua ʻike mākou a pau ke kumu kūʻai nui o nā pā lithium i ka noʻonoʻo ʻana i nā ʻano ʻano ʻē aʻe, akā kūpono ke ʻōlelo ʻana ua lilo lākou i mea kūʻai aku no ka hoʻohui ʻana i nā kukui alanui solar. I nā makahiki 6 i hala iho nei, ua emi ke kumukūʻai o ka pākaukau lithium ma kahi o 80%. Aia nā ʻano ʻokoʻa o nā pākahi lithium hiki ke hoʻohana ʻia no nā ʻōnaehana Solar Street Light. Ua hōʻike ʻia kā mākou ʻike ʻo ka hopena maikaʻi loa no ka hoʻomālamalama ʻana o ka lā ʻo ka pā LiFePO4.

ʻO Lithium-ion (li-ion) i kēia manawa ka mea maʻamau i hoʻopaʻa hou ʻia no nā huahana lawe lima a me ka lā. Ua hoʻohana ke ʻano kahiko o nā pā lithium i ka metala lithium, akā no ka pilikia ʻole a me nā pilikia palekana, ua hoʻohana ʻia nā ion lithium i kēia manawa. ʻOi aku ka maikaʻi o nā pākahi Lithium-ion o ka ikehu kiʻekiʻe a me ka mālama haʻahaʻa ma o ka hoʻohālikelike ʻana me Ni-Cd a me Ni-MH e hoʻolilo iā lākou i ka hopena maikaʻi loa no nā huahana kukui lā a me nā mea uila a i ʻole nā kaʻa.

ʻO nā ʻano maʻamau maʻamau o nā pākahi Lithium-ion ʻo Li-cobalt, Li-manganese, Li-phosphate a me NMC (lithium nickel manganese cobalt oxide). Ke hoʻohana nei kēlā me kēia mau ʻona Lithium-ion i nā mea cathode like ʻole, no laila he ʻokoʻa nā pono a me nā pōʻino. Hoʻohana nui ʻia nā pākahi Li-cobalt i nā mea uila uila, ʻoiai hoʻohana ʻia nā pā li-phosphate i nā kaʻa uila, nā kukui uila a me nā kukui lā.

ʻO ka hoʻolālā pākaukau Li-ion. Puna – http://electronicdesign.com

ʻO nā ʻōhua Lithium Iron Phosphate

ʻOi aku ka palekana o nā pali Lithium Iron Phosphate ma mua o nā ʻāpana Li-cobalt a me Li-manganese, a ʻoi aku ka lōʻihi o ke ola a hiki ke hoʻokele i nā au kiʻekiʻe. Eia nō naʻe, ʻo ka hemahema o nā ʻalā LiFePO4 ka loaʻa ʻana o kekahi o nā mana haʻahaʻa loa o nā ʻano pākaukau lithium-ion āpau. ʻOiai ʻoi aku ka haʻahaʻa ma ka hoʻohālikelike ʻana me nā ʻano ʻokoʻa lithium-ion ʻē aʻe, kūpono loa ia no nā kukui alanui o ka lā a i ʻole nā kukui waikahe e koi ʻole i ka nui o ka uila e mana i ka ʻōnaehana.

Nā Pōmaikaʻi Bateri Lithium-ion

He kiʻekiʻe ka ikehu kiʻekiʻe o nā pākahi Lithium-ion, ʻoi aku ka kiʻekiʻe ma mua o Ni-MH, ʻelua ʻoi aku ke kiʻekiʻe ma mua o Ni-Cd a ʻoi aku ma mua o ʻekolu mau manawa kiʻekiʻe ma mua o nā pihi waika lead.
Loaʻa ka haʻahaʻa haʻahaʻa o ka hoʻokuʻu ʻia ʻana o nā pākahi Li-ion
ʻAʻole hoʻomohala nā pila Li-ion i kahi hopena hoʻomanaʻo;
ʻAʻole mālama ʻia nā pākahi Li-ion, ʻoi aku ka maikaʻi no ka kukui lā;
Mālama ʻia nā ʻona Li-ion no ke kaiapuni me ka loaʻa ʻole o nā mea ʻawaʻawa;
Ma muli o ke kiʻekiʻe o ka ikehu kiʻekiʻe, liʻiliʻi ka nui o nā pā li-ion.
Hiki i nā pila Li-ion ke hoʻouka wikiwiki i ka mana piha;
Palekana - ʻoi aku ka maikaʻi o ka wela a me ka paʻa kemika i nā pā li-phosphate.

ʻO nā pōʻino ʻole o ka Battery Lithium-ion

He kiʻekiʻe nā kumu kūʻai o nā ʻona Li-ion e hopena i nā kumukūʻai kūʻai kiʻekiʻe.
Pono nā pila Li-ion i nā kaapuni pale e kaupalena i ka volta a me nā au a me ka palekana ʻoi aku ka maikaʻi;
Hāʻawi kekahi mau pākahi Li-ion e like me ka li-phosphate i nā uku hoʻokuʻu haʻahaʻa;

Ka pakuhi hoʻohālikelike ikehu kiko'ī hiki ke hoʻouka hou ʻia
