I ka hoʻoikaika ʻana o ke kaua ma waena o Rūsia a me Ukraine, ʻike hou ʻia nā ʻōnaehana mālama ikehu home PV i ke kūʻokoʻa o ka mana, a ʻo ke koho ʻana i ka pākaukau i ʻoi aku ka maikaʻi no kāu ʻōnaehana PV ua lilo ia i mea nui loa no ka poʻe kūʻai. Ma ke ʻano he mea hana pākaukau lithium nui ma Kina, paipai mākouPāʻani Lithium Solarno kou home. 
ʻO nā pākahi Lithium (a i ʻole nā pā Li-ion) kekahi o nā ʻōnaehana mālama ikehu hou loa no nā ʻōnaehana PV. Me ka ʻoi aku ka maikaʻi o ka ikehu, ʻoi aku ka lōʻihi o ke ola, ke kumu kūʻai kiʻekiʻe o kēlā me kēia pōʻaiapuni a me nā mea maikaʻi ʻē aʻe ma mua o nā pākaukau lead-acid kuʻuna, ua lilo kēia mau mea i mea maʻamau i nā ʻōnaehana solar off-grid a hybrid. ʻO nā ʻano o ka waiho ʻana i nā Batri ma kahi nānā No ke aha e koho ai i ka Lithium ma ke ʻano he hopena no ka mālama ʻana i ka ikehu home? ʻAʻole wikiwiki loa, e nānā mua kākou i ke ʻano o nā pākaukau mālama ikehu i loaʻa. Lithium-ion Solar batteries Ua ulu nui ka hoʻohana ʻana i ka lithium ion a i ʻole lithium i nā makahiki i hala iho nei. Hāʻawi lākou i kekahi mau pono nui a me nā hoʻomaikaʻi ʻana ma luna o nā ʻano ʻenehana ʻenehana ʻē aʻe. Hāʻawi nā pākahi solar Lithium-ion i ka ikehu kiʻekiʻe, paʻa a pono ka mālama liʻiliʻi. Eia kekahi, e mau ana ko lakou mana ma hope o ka lōʻihi o ka hana. He 20 makahiki ka lōʻihi o ke ola ʻana o nā pākahi Lithium. Ke mālama nei kēia mau pākaukau ma waena o 80% a me 90% o ko lākou hiki ke hoʻohana. Ua hoʻonui nui nā ʻenehana lithium i nā ʻoihana he nui, me nā kelepona kelepona a me nā kamepiula, nā kaʻa uila a me nā mokulele kalepa nui, a ke lilo nei i mea nui no ka mākeke solar photovoltaic. Na Bateri Solar Gel Lead Ma ka ʻaoʻao ʻē aʻe, he 50 a 60 wale nō ka nui o nā pākaukau lead-gel o ko lākou hiki ke hoʻohana. ʻAʻole hiki ke hoʻokūkū ʻia nā ʻakika Lead-acid me nā pā lithium i ke ʻano o ke ola. Pono ʻoe e hoʻololi iā lākou ma kahi o 10 mau makahiki. No kahi ʻōnaehana me kahi ola 20-makahiki, ʻo ia hoʻi, pono ʻoe e hoʻolilo i ʻelua manawa i nā pila no kahi ʻōnaehana mālama ma luna o nā pā lithium i ka manawa like. ʻO nā Bateri Solar Lead-acid ʻO nā mea mua o ka pākaukau lead-gel he mau ʻakika lead-acid. ʻAʻole kūʻai nui lākou a loaʻa iā lākou ka ʻenehana oʻo a paʻa. ʻOiai ua hōʻoia lākou i ko lākou waiwai ma mua o 100 mau makahiki ma ke ʻano he kaʻa a i ʻole ka mana pilikia, ʻaʻole hiki iā lākou ke hoʻokūkū me nā pā lithium. Ma hope o nā mea a pau, he 80 pakeneka ko lākou pono. Eia naʻe, loaʻa iā lākou ke ola lawelawe pōkole loa ma kahi o 5 a 7 mau makahiki. ʻOi aku ka haʻahaʻa o ko lākou ikehu ma mua o nā pā lithium-ion. ʻOi loa i ka wā e hoʻohana ai i nā ʻokoʻa alakaʻi kahiko, hiki ke hana ʻia ke kinoea oxyhydrogen pahū inā ʻaʻole i hoʻoheheʻe ʻia ka lumi hoʻokomo. Eia naʻe, palekana nā ʻōnaehana hou e hana. ʻO Redox Flow Battery Ua kūpono lākou no ka mālama ʻana i ka uila i hana hou ʻia me ka hoʻohana ʻana i nā photovoltaics. No laila, ʻaʻole nā hale noho a i ʻole nā kaʻa uila nā wahi o ka noi ʻana i nā pā uila redox flow, akā ʻoihana a me nā ʻoihana, pili pū kekahi i ka ʻoiaʻiʻo ke kumukūʻai nui loa. ʻO nā ʻanuʻu holo Redox kekahi mea e like me ka rechargeable fuel cell. ʻAʻole like me ka lithium-ion a me ke alakaʻi-acid bateria, ʻaʻole mālama ʻia ka mea mālama i loko o ka pā akā ma waho. ʻElua mau mea hoʻoheheʻe electrolyte wai ma ke ʻano he waihona mālama. Mālama ʻia nā hāʻina electrolyte i loko o nā pahu waho maʻalahi loa. Hoʻomoʻi wale ʻia lākou ma o nā kelepona pākaukau no ka hoʻouka ʻana a i ʻole ka hoʻokuʻu ʻana. ʻO ka pōmaikaʻi ma ʻaneʻi ʻaʻole ia ka nui o ka pākaukau akā ʻo ka nui o nā pahu e hoʻoholo ai i ka hiki ke mālama. Brine Stormakahiki ʻO Manganese oxide, carbon activated, pulupulu a me brine nā ʻāpana o kēia ʻano mālama. Aia ka manganese oxide ma ka cathode a me ka carbon activated ma ka anode. Hoʻohana pinepine ʻia ka pulupulu cellulose ma ke ʻano he mea hoʻokaʻawale a me ka brine ma ke ʻano he electrolyte. ʻAʻole i loko o ka waihona brine kekahi mea ʻino i ke kaiapuni, ʻo ia ka mea e hoihoi nui ai. Eia nō naʻe, i ka hoʻohālikelike ʻana - ʻoi loa ka haʻahaʻa o ka volta o nā pā lithium-ion 3.7V - 1.23V. Hydrogen ma ke ano he Mana Mana ʻO ka pōmaikaʻi koʻikoʻi ma aneʻi, hiki iā ʻoe ke hoʻohana i ke koena o ka ikehu lā i hana ʻia i ke kauwela wale nō i ka hoʻoilo. ʻO ka wahi noi no ka mālama ʻana i ka hydrogen ka mea nui ma ka mālama ʻana i ka uila a me ka wā lōʻihi. Eia nō naʻe, aia kēia ʻenehana mālama i kona wā kamaliʻi. No ka mea, pono e hoʻololi hou ʻia ka uila mai ka hydrogen i ka uila ke pono, nalowale ka ikehu. No kēia kumu, ʻo ka maikaʻi o nā ʻōnaehana mālama ma kahi o 40% wale nō. ʻO ka hoʻohui ʻana i kahi ʻōnaehana photovoltaic he paʻakikī loa a no laila ke kumu kūʻai nui. ʻO kahi electrolyzer, compressor, hydrogen tank a me kahi pākaukau no ka mālama manawa pōkole a ʻoiaʻiʻo hoʻi he pono wahie. Aia kekahi mau mea hoʻolako e hāʻawi i nā pūnaewele piha. 
ʻO nā Bateri LiFePO4 (a i ʻole LFP) ʻO ka hopena maikaʻi loa no ka mālama ʻana i ka ikehu ma nā ʻōnaehana PV noho LiFePO4 & Palekana ʻOiai ua hāʻawi ʻia nā pāʻani lead-acid i ka manawa kūpono e alakaʻi ai ma muli o ko lākou pono mau e hoʻopiha hou i ka waika a me ka haumia o ke kaiapuni, ʻike ʻia nā pānaʻi lithium hao hao phosphate (LiFePO4) cobalt-free no ko lākou palekana ikaika, ʻo ka hopena o kahi paʻa loa. haku mele. ʻAʻole lākou e pahū a puhi paha i ke ahi ke loaʻa i nā hanana pōʻino e like me ke kuʻi ʻana a i ʻole ka pōkole pōkole, e hōʻemi nui ana i ka manawa o ka ʻeha. E pili ana i nā pākī lead-acid, ʻike nā mea a pau he 50% wale nō ka hohonu o ka hoʻokuʻu ʻana o ka mana i loaʻa, i ka hoʻohālikelike ʻana i nā pākiʻi lead-acid, loaʻa nā pā lithium hao phosphate no 100% o ko lākou mana helu. Ke lawe ʻoe i kahi pākaukau 100Ah, hiki iā ʻoe ke hoʻohana i ka 30Ah a i ka 50Ah o nā pākī lead-acid, aʻo nā pā lithium hao phosphate he 100Ah. Akā i mea e hoʻolōʻihi ai i ke ola o ka lithium iron phosphate solar cell, ʻōlelo pinepine mākou i nā mea kūʻai aku e hahai i ka 80% hoʻokuʻu i kēlā me kēia lā, hiki ke hana i ke ola pākaukau ma mua o 8000 cycles. Laulā Mahana Laulā ʻO nā ʻokoʻa ʻelua o ka lā alakaʻi-acid a me nā waihona pākaukau lā lithium-ion e nalowale ka hiki i nā kaiapuni anu. He mea liʻiliʻi ka nalowale o ka ikehu me nā ʻokoʻa LiFePO4.

Kiʻekiʻe Energy Density Ke hoʻohālikelike ʻia me nā pākaʻi lead-acid, ʻaneʻane ʻehā mau manawa ʻoi aku ka māmā o nā pā lithium iron phosphate, no laila, ʻoi aku ka nui o ka ikehu electrochemical a hiki ke hāʻawi i ka nui o ka ikehu no kēlā me kēia paona kaumaha - hāʻawi ʻia i 150 watt-hola (Wh) o ka ikehu ma ke kilo (kg. ) i hoʻohālikelike ʻia me 25Wh/kg no nā ʻōhua kepau-ʻakika paʻa mau. No nā noi solar he nui, hāʻawi kēia i nā pōmaikaʻi koʻikoʻi e pili ana i nā kumukūʻai haʻahaʻa haʻahaʻa a me ka wikiwiki o ka hoʻokō ʻana i ka papahana. ʻO kekahi pōmaikaʻi koʻikoʻi ʻo ia ʻaʻole i hoʻopaʻa ʻia nā pākahi Li-ion i ka hopena hoʻomanaʻo i kapa ʻia, hiki ke loaʻa me nā ʻano ʻokoʻa ʻē aʻe i ka wā e hāʻule koke ai ka uila uila a hoʻomaka ka mea hana i nā hoʻokuʻu ma hope me ka hoʻemi ʻana o ka hana. I nā huaʻōlelo ʻē aʻe, hiki iā mākou ke ʻōlelo he "non-addictive" nā pā Li-ion a ʻaʻole e holo i ka pilikia o ka "addiction" (nalo o ka hana ma muli o kona hoʻohana ʻana). ʻO nā noi ʻana o ka pākaukau Lithium i ka Home Solar Energy Hiki i ka ʻōnaehana ikehu lā home ke hoʻohana i hoʻokahi pākahi wale nō a i ʻole kekahi mau ʻokoʻa e pili ana i ka moʻo a/a i ʻole ke ʻano like ʻole (ka panakō pākahi), ma muli o kāu pono. ʻElua ʻano ʻōnaehana hiki ke hoʻohananā panakō pākahi lā lithium-ion: Off Grid (hoʻokaʻawale, me ka pili ʻole i ka mānoanoa) a me ka Hybrid On+Off Grid (pili ʻia i ka pā a me nā pihi).
