ʻO ka pūʻolo mana pākahi no nā lako kī o ka ʻōnaehana mālama ikehu lā

I kēia manawa, ʻo nā pākahi maʻamau i nā ʻōnaehana mālama ikehu photovoltaic ʻo ia ka mālama ʻana i ka ikehu electrochemical, e hoʻohana ana i nā mea kemika e like me ka media mālama ikehu, a ʻo ke kaʻina hana a me ka hoʻokuʻu ʻana e hele pū ʻia me nā hopena kemika a i ʻole nā ​​hoʻololi ʻana i ka media mālama ikehu.ʻO ka mea nui e hoʻokomo i nā ʻāpana lead-acid, nā pihi kahe, nā pā sodium-sulfur, nā pā lithium-ion, a me nā mea ʻē aʻe.

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 ka electrolyte he sulfuric acid solution.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 hoʻopaʻa ʻia, ʻo ka mea nui o nā electrodes maikaʻi a maikaʻi ʻole ke alakaʻi sulfate.Hoʻohana ʻia i nā ʻōnaehana mālama ikehu photovoltaic, ʻoi aku ka nui o ʻekolu mau ʻano, ʻo nā pahu wai kepau-acid i kahe ʻia (FLA, kahe wai kahe wai), VRLA (Valve-Regulated Lead Acid Battery), me ke alakaʻi i hoʻopaʻa ʻia ʻo AGM Aia ʻelua mau ʻano o nā pahu mālama a me GEL pahu pahu pahu pahu i hoʻopaʻa ʻia i ka gel.ʻO nā ʻeke kalapona keʻokeʻo ke ʻano o ka pākaukau lead-acid capacitive.He ʻenehana ia i hoʻomohala ʻia mai nā pākahiko lead-acid maʻamau.Hoʻohui ʻo ia i ke kalapona i hoʻāla ʻia i ka electrode maikaʻi ʻole o ka pākaukau lead-acid.ʻAʻole nui ka hoʻomaikaʻi ʻana, akā hiki iā ia ke hoʻomaikaʻi maikaʻi i ka hoʻopiʻi a me ka hoʻokuʻu ʻana i kēia manawa a me ke ola pōʻai o nā pākī lead-acid.Loaʻa iā ia nā hiʻohiʻona o ka mana kiʻekiʻe, ke ola pōʻai lōʻihi a me ke kumu kūʻai haʻahaʻa.

ʻO ka Battery Lithium Ion

Hoʻokumu ʻia nā ʻāpana lithium-ion i ʻehā mau ʻāpana: mea electrode maikaʻi, mea electrode maikaʻi ʻole, separator a me electrolyte.Wahi a nā mea like ʻole i hoʻohana ʻia, ua māhele ʻia lākou i ʻelima mau ʻano: lithium titan-ate, lithium cobalt oxide, lithium manganate, lithium iron phosphate, a me ka lithium ternary.Ua komo nā pākahi lithium a me nā pākahi lithium ternary i ka mākeke nui.

ʻAʻole maikaʻi loa a maikaʻi ʻole paha nā pākahi lithium iron phosphate, akā aia kēlā me kēia me kāna pono ponoʻī.Ma waena o lākou, ʻoi aku ka maikaʻi o nā pākahi lithium ternary i ka nui o ka mālama ʻana i ka ikehu a me ke kūpaʻa haʻahaʻa haʻahaʻa, ʻoi aku ka maikaʻi no nā ʻāpana mana;ʻO ka lithium iron phosphate he ʻekolu ʻaoʻao.ʻO kekahi o nā pōmaikaʻi he palekana kiʻekiʻe, ʻo ka lua ka lōʻihi o ke ola pōʻai, a ʻo ke kolu ka haʻahaʻa haʻahaʻa o ke kumu kūʻai.No ka mea, ʻaʻohe metala makamae o nā pākahi lithium iron phosphate, ʻoi aku ka haʻahaʻa o nā kumukūʻai hana a ʻoi aku ka maikaʻi no nā ʻuila mālama ikehu.ʻIke ʻia ʻo Blue Joy i ka hana ʻana i ka pākaukau Lithium ion 12V-48V.
