Ke hoʻonui wikiwiki nei ka mākeke mālama ikehu

ʻO ka mālama ʻana i ka ikehu electrochemical i hoʻomalu ʻia enā pākahi lithium-ion, ʻo ia ka ʻenehana mālama ikehu me ka laulā o nā noi a me ka hiki ke hoʻomohala.ʻOiai ʻo ia ka mākeke kūʻai a i ʻole ka mākeke hou, ua noho nā pākahi lithium i kahi kūlana monopoly i ka mālama ʻana i ka ikehu electrochemical.I ke ao holoʻokoʻa, mai 2015 a 2019, e pōmaikaʻi ana i ka hoʻomohala wikiwiki ʻana o nā pā lithium, ka hapa ohoʻopaʻa ʻana i ka ikehu pākahi lithium-ionma ka mākeke kūloko i piʻi mai 66% a i 80.62%.

Mai ka hiʻohiʻona o ka hoʻolaha ʻenehana, ma waena o nā papahana mālama mālama ikehu electrochemical hou i ka honua, ʻo ka mana hoʻokomo o nā pā lithium-ion i helu ʻia no ka hapa nui loa o 88%;Ua loaʻa i ka mālama ʻana i ka ikehu pākaukau lithium home ka 619.5MW o ka mana i hoʻokomo hou ʻia i loko o ka makahiki i 2019, he piʻi o 16.27% e kūʻē i ke ʻano I ka mākeke hou, ua piʻi ka piʻi o ka hoʻokomo ʻana o nā pā lithium mai 78.02% i 2018 a i 97.27%.

I kēia manawa, ʻo nā pākahi lithium-ion a me nā ʻāpana lead-acid nā ala ʻenehana nui no ka mālama ʻana i ka ikehu electrochemical, a ʻoi aku ka maikaʻi o ka hana nui o nā pā lithium-ion ma mua o nā pākiʻi lead-acid, a e hoʻololi mālie i nā pākiʻi lead-acid i kēia manawa. i ka wā e hiki mai ana, a ke manaʻo ʻia nei e hoʻonui ka mākeke.

Ke hoʻohālikelike ʻia me nā pākiʻi lead-acid maʻamau, ʻekolu mau pōmaikaʻi nui nā pā lithium: (1) ʻO ka nui o ka ikehu o nā pā lithium-ion he 4 mau manawa ma mua o nā pākī lead-acid, a ʻoi aku ka maikaʻi o ka hiki a me ke kaumaha ma mua o ka nui o nā pākiʻi lead-acid. ;(2) ʻOi aku ka maikaʻi o nā ʻōhua Li-ion, a ʻoi aku ka maikaʻi o nā pā lithium-ion.ʻAʻole i loko o ka pākaukau nā mea ʻino e like me ka mercury, ke kēpau, a me ka cadmium.He pākaukau ʻōmaʻomaʻo maoli.Eia kekahi, ʻoi aku ka ikaika o nā pā lithium-ion a ʻoi aku ka maikaʻi o ka hoʻololi ʻana i ka ikehu ma mua o nā pā alakaʻi.ʻOi aku ka liʻiliʻi o ka pilikia ma mua o nā pākahi kepau;(3) He lōʻihi ke ola pōʻaiapuni o ka lithium-ion.I kēia manawa, ʻekolu a ʻehā mau manawa ke ola o nā pākahi lithium-ion ma mua o nā pākiʻi lead-acid.ʻOiai ʻoi aku ka kiʻekiʻe o ke kumu kūʻai mua, ʻoi aku ka maikaʻi i ka wā lōʻihi.

I ka wā lōʻihi, "photovoltaic + mālama ikehu"ʻO ka paʻa ʻana o ke kumukūʻai uila ka pahuhopu nui o ka hoʻokō ʻana i nā photovoltaics ma ke ʻano he hanauna hou o ka ikehu no ke kanaka i nā makahiki 100 e hiki mai ana.Ua lilo ʻo Economics i mea hoʻoikaika nui i ka ulu ʻana o ka noi.
