lithium pākaukau VS lead-acid pākaukau, ʻoi aku ka maikaʻi?

ʻO ka palekana o nā pākahi lithium a me nā pākī lead-acid he wahi hoʻopaʻapaʻa ma waena o nā mea hoʻohana.Wahi a kekahi poʻe, ʻoi aku ka palekana o nā ʻeke lithium ma mua o nā pākī lead-acid, akā manaʻo kekahi ʻē aʻe.Mai ka hiʻohiʻona o ke ʻano o ka pākaukau, ʻo nā ʻeke pākahi lithium i kēia manawa he 18650 mau ʻāpana no ka hoʻopili ʻana, a ʻo nā pākaʻi lead-acid ke kumu mālama pono ʻole ʻia nā pākaʻi lead-acid me ka hana hoʻopaʻa sila maikaʻi, a ʻo nā kumu pilikia o nā mea ʻelua ke kumu like.ʻO wai ka mea palekana, e nānā wale i lalo a ʻike ʻoe!

pākahi lithium:

ʻO nā ʻōhua lithium kahi ʻano o nā pā e hoʻohana ana i ka metala lithium a i ʻole ka lithium alloy e like me ka mea electrode maikaʻi ʻole a hoʻohana i kahi hopena electrolyte non-aqueous.Hiki ke hoʻokaʻawale ʻia nā ʻuala lithium i ʻelua mau ʻāpana: ʻo nā pākahi metala lithium a me nā pā lithium-ion.I ka makahiki 1912, ua noi mua ʻia a ua aʻo ʻia e Gilbert N. Lewis nā pākahi metala lithium.Ma muli o nā waiwai kemika ikaika loa o ka metala lithium, ʻo ka hoʻoili ʻana, ka mālama ʻana, a me ka hoʻohana ʻana i ka metala lithium he kiʻekiʻe kiʻekiʻe nā koi kūlohelohe.No laila,nā pākahi lithiumʻaʻole i hoʻohana ʻia no ka manawa lōʻihi.Me ka hoʻomohala ʻana o ka ʻepekema a me ka ʻenehana, ua lilo nā pā lithium i mea nui.

ʻO nā ʻanuʻu kepau-ʻakika:

ʻO ka pākaukau Lead-acid (VRLA) kahi pākaukau mālama nona nā electrodes i hana nui ʻia me ke kēpau a me kāna mau oxides, a ʻo kāna electrolyte he solution sulfuric acid.I ka hoʻokuʻu ʻana o kahi pākaukau lead-acid, ʻo ka mea nui o ka electrode maikaʻi ke alakaʻi dioxide, a ʻo ka mea nui o ka electrode maikaʻi ʻole ke alakaʻi;i ka moku'āina i hoʻopiʻi ʻia, ʻo nā mea nui o nā electrodes maikaʻi a maikaʻi ʻole ke alakaʻi sulfate.

He 2.0V ka volt nominal o ka pahu pahu lead-acid hoʻokahi, hiki ke hoʻokuʻu ʻia i 1.5V a hiki ke hoʻouka ʻia i 2.4V.I loko o nā noi, hoʻohana pinepine ʻia nā 6 mau pahu pahu alakaʻi-acid hoʻokahi i loko o ka moʻo e hana i kahi pākahi 12V lead-acid.Aia kekahi 24V, 36V, 48V a pēlā aku.

ʻO wai ka mea ʻoi aku ka palekana, ʻo ka pā lithium a i ʻole ka pākaukau lead-acid?

Mai ka hiʻohiʻona o ka pale palekana o ka pākaukau, ua hoʻolālā ʻia nā valves palekana ma nā cell 18650, ʻaʻole hiki ke hoʻokuʻu wale i ke kaomi kūloko keu, akā hoʻokaʻawale kino hoʻi i ka pā uila mai ke kaapuni o waho, e like me ka hoʻokaʻawale kino ʻana i ke kelepona e hōʻoia i ka palekana. o nā pūnaewele ʻē aʻe i loko o ka pūʻolo pila.Eia kekahi, ua hoʻolako pinepineʻia nā pahu pahu lithium me nā papa pale BMS, hiki ke hoʻomalu pono i ke kūlana o kēlā me kēia pūnaewele i loko o ka pahu pahu, a hoʻoponopono pololei i ka pilikia o ka overcharge a me ka hoʻokuʻuʻana mai ke kumu kumu.

Hiki i ka ʻōnaehana hoʻokele pākaukau ʻo Lithium BMS ke hāʻawi i ka pale piha i ka pākaukau, nā hana e komo: uku / hoʻokuʻu i ka pale wela kiʻekiʻe a haʻahaʻa;hoʻokahi cell overcharge / overdischarge voltage pale;hoʻopaʻa / hoʻokuʻu i ka mālama ʻana i ka overcurrent;pale kaulike;pale kaapuni pōkole;Hoʻomanaʻo a ʻoi aku.

ʻO ka electrolyte o kapūʻolo pākahi lithiumhe hopena hui ʻia o ka paʻakai lithium a me ka mea hoʻoheheʻe organik, a ʻo ka paʻakai lithium hiki ke kūʻai ʻia he lithium hexafluorophosphate.Hiki i kēia mea ke hoʻoheheʻe wela i nā wela kiʻekiʻe a loaʻa i kahi hopena thermochemical me ka nui o ka wai a me nā mea hoʻoheheʻe organik e hōʻemi i ka paʻa Thermal o ka electrolyte.

Hoʻohana nui ka mana lithium i ka lithium iron phosphate.ʻO ka paʻa PO i loko o ka lithium iron phosphate crystal he paʻa a paʻakikī ke decompose.ʻOiai i ka wela kiʻekiʻe a i ʻole ka hoʻonui ʻana, ʻaʻole ia e hāʻule a hoʻohua i ka wela a i ʻole e hana i nā mea hoʻoneʻe ikaika e like me ka lithium cobaltate.Palekana maikaʻi.Ua hōʻike ʻia ma ka hana maoli, ʻike ʻia kahi helu liʻiliʻi o nā laʻana e puhi i ka wā acupuncture a i ʻole nā ​​hoʻokolohua pōkole pōkole, akā ʻaʻohe hanana pahū.Ua hoʻomaikaʻi maikaʻi ʻia ka palekana o nā pā uila lithium.

ʻO ka ʻokoʻa, ʻaʻohe pale o ka ʻōnaehana BMS i nā pākaʻi lead-acid.Me he mea lā ʻaʻole i lawa ka pale ʻana o nā pākika Lead-acid koe wale nō nā kiwi palekana.ʻAʻole loaʻa ka pale BMS.ʻAʻole hiki ke hoʻopau ʻia ka nui o nā charger haʻahaʻa ma hope o ka hoʻopiha piha ʻana.ʻAʻole mamao loa ka pale palekana mai nā pā lithium.Hoʻohui ʻia me kahi loina haʻahaʻa haʻahaʻa, maikaʻi ia iā ʻoe ke noho maikaʻi.

Hiki pinepine ka pahū ʻana i nā kaʻa uila, ʻo ka hapa nui o ia mau mea ma muli o ka hoʻouka ʻana a me ka hoʻokuʻu ʻana.Ua wehewehe mai kekahi poʻe akamai he lōʻihi loa ka hoʻopiʻi ʻana o nā ʻaʻa wai kēpau, a ke hoʻopiʻi ʻia a hiki i ka hopena, ma hope o ka hoʻololi ʻia ʻana o nā pou ʻelua i mau mea pono, inā hoʻomau lākou i ka hoʻopiʻi ʻana, nui ka uila.ʻO ka hydrogen, ke kinoea oxygen.Ke 4% ka nui o kēia kinoea huila i ka lewa, ua lohi loa ka pakele.Inā ālai ʻia ka lua hoʻopau a i ʻole nui loa ke kinoea, e pahū ia i ka wā e hālāwai ai me kahi lapalapa hāmama.E hoʻopōʻino ia i ka pākaukau i ka mālamalama, a e hōʻeha i nā kānaka a me nā hihia koʻikoʻi.ʻO ia hoʻi, ke hoʻonui ʻia ka pākaukau lead-acid, e hoʻonui ia i ka manawa o ka pahū.I kēia manawa, ʻaʻole i hana nā pākaʻi lead-acid ma ka mākeke i kekahi "palekana overcharge", e hana ana i nā ʻakika lead-acid i ka hoʻouka ʻana, ʻoi aku ka maikaʻi ma ka hopena o ka hoʻouka ʻana, weliweli loa.

ʻO ka mea hope loa, inā ʻino ke ʻano o ka pākaukau ma muli o ka hoʻokuʻi ʻia ʻana, ʻoi aku ka palekana o nā ʻakika lead-acid ma mua o nā pā lithium.Eia nō naʻe, i kēia pae o ka pōʻino, ua hōʻike mua ʻia ka mea pākaukau i kahi ākea ākea, a ʻaʻole hiki ke kamaʻilio e pili ana i ka pahū.

Mai nā pōʻino palekana ma luna o nā ʻeke akika a me nā pā lithium iron phosphate, hiki ke ʻike ʻia ʻo ka pōʻino palekana nui loa o nā pāleka lead-acid aia i loko o kā lākou mea constituent.ʻO nā electrodes o nā pākī lead-acid i hana nui ʻia me ke kēpau a me kāna mau oxides, a ʻo ka electrolyte kahi hopena sulfuric acid.ʻAʻole kiʻekiʻe loa ka paʻa o kēia mau mea hoʻohui.Inā loaʻa kahi ulia leaka a pahū paha, ʻoi aku ka kiʻekiʻe o ka pōʻino ma mua o nā pā lithium.

Hōʻuluʻulu manaʻo:

Mai ka hiʻohiʻona o ka palekana o ka pākaukau a me ka hoʻolālā redundancy, hiki ke hōʻoia pono i ka palekana o nā mea hoʻohana, nā ʻokoʻa palekana palekana.ʻOi aku ka palekana o ka pākaukau lithium a i ʻole ka ʻakika lead?I kēia pae, ka mea palekana onā pākahi lithiumʻoi aku ke kiʻekiʻe.
