Hoʻohana ʻo China Tower i nā ʻeke lithium e hoʻololi i nā pākī lead-acid

HOPPT BATTERY analysis: New battery energy storage uses more and more lithium batteries, gradually replaces lead-acid batteries, and is more and more widely used in the energy storage market. The process of replacing lead-acid batteries in iron tower systems with lithium batteries has begun. Lithium iron phosphate batteries have low production costs and high cycle times. The core scenario of lithium battery applications in the communications market is base station backup power.

pehea e hoʻololi ai i ka pākaukau ʻakika alakaʻi me ka lithium ion

ʻO 2020 Tower Communication Base Station e hoʻololi i ka 600-700,000 mau hale kiaʻi o nā Bateri Lithium.

ʻO ka pōmaikaʻi mai ka hoʻololi ʻana i nā kahua waihona waihona, ka mākeke ākea ākea no ka mālama ʻana i ka ikehu kamaʻilio i lawe ʻia e ka hoʻolaha nui ʻana o nā kahua kahua 5G, a me ka hoʻolaha wikiwiki ʻana o ka mālama ʻana i ka mana ma ka ʻaoʻao hana mana, ʻaoʻao grid, a me ka ʻaoʻao mea hoʻohana. ke ulu wikiwiki nei ka mākeke mālama ʻenehana lithium. Ma ka hopena o Iune 2019, ua loaʻa iā China Tower he 65,000 5G e pono ai ke kūkulu hale kahua kahua, a ua manaʻo ʻia e loaʻa iā ia he 100,000 5G e pono ai ke kūkulu hale kahua i kēia makahiki.

1) Manaʻo ʻia ka mākeke uila: manaʻo ʻia ke kūʻai aku ʻana o nā kaʻa ikehu hou i ka 7 miliona ma 2025, a ʻoi aku ke kūʻai aku ma waho o 6 miliona ma 2025. I ka makahiki 2020, e pili ana ka 85GWh i ke koi ʻana o ka pā uila ma waho. Ke hoʻomau nei ka hoʻonui ʻana o ka wahi no ka ʻoihana pākaukau mana, a ke manaʻo ʻia nei e ulu ka pono o nā pihi mana ma kahi o 2020% i 90.

2) ʻO ka mākeke pākaukau ʻaʻole mana: ʻO ka mākeke mālama ʻenehana lithium i kēia manawa i kona wā kamaliʻi. ʻO ka hoʻololi ʻana i ka waikawa lead o nā pā lithium i nā kahua kahua kamaʻilio hale kiaʻi ka wahi koi nui loa. I ka makahiki 2018, he 120,000 mau hale kiaʻi he 1.5 mau hale kiaʻi, e hoʻohana ana ma kahi o 2019GWh o nā pā lithium. ʻEkolu haneli tausani hale kiaʻi e hoʻololi ʻia ma 4, me ka hoʻohana ʻana i ka 5-600,000GWh o nā pā lithium, a me 700,000-2020 mau hale e manaʻo ʻia e hoʻololi ʻia i 8, i hoʻolālā ʻia e 25GWh. E hoʻololi ʻia nā hale kiaʻi āpau ma kahi o XNUMXGWh, ʻo ia ka nui.

3) ʻAʻohe pono e hopohopo e pili ana i ke kuhikuhi maʻamau o nā pā lithium: inā he mau kaʻa ikehu hou, nā kelepona paʻa lima 5G, nā wahi hoʻihoʻi kahua kahua, a me nā pihi mālama ikehu, ʻo nā mea a pau e hoʻoholo a ulu mau. Me ka holomua o ka pūnaewele puni honua a me ka Pūnaewele o nā mea a pau, mai ka uea a hiki i ke kelepona, ʻo nā pā Lithium ka hopena mana maikaʻi loa i kēia manawa.

He aha ka hōʻailona a ka hale kiaʻi hao e hoʻouna ai i ka wā e hoʻololi ai i nā ʻakika lead-acid me nā pā lithium?

Ma ke ʻano he hui lawelawe ʻoihana hoʻonaʻauao aupuni nui, ʻo Tower Company he 1.9 miliona mau kahua kahua. No ka manawa lōʻihi, ua hoʻohana nui nā lako mana hoʻihoʻi kumu kumu o China Tower Corporation Limited i nā ʻenekini lead-acid, a i kēlā me kēia makahiki ke kūʻai nei ʻo ia ma kahi o 100,000 tons o nā pākika lead-acid. He pōkole ka lawelawe ʻana o nā ʻeke akika, haʻahaʻa hana, a me ke alakaʻi metala kaumaha. Inā hoʻolei ʻia, e hoʻohaumia ʻia ka lua i ke kaiapuni inā ʻaʻole i mālama pono ʻia.

Eia nō naʻe, i ka hoʻohālikelike ʻia me nā pākī lead-acid, ʻoi aku ka maikaʻi o nā pā lithium i ka nui o ka ikehu kiʻekiʻe a me ke ola lawelawe lōʻihi. No kēia kumu, ua hoʻomaka ka Hui Tower ma 2015 a ua hoʻokō ʻo ia i nā hoʻokolohua cascading e hoʻololi i nā pākaukau lead-acid me nā ʻona ma mua o 3000 mau kahua kahua ma 12 mau panalāʻau a me nā kūlanakauhale. Hōʻoia ka palekana a me ka ʻenehana a me ka hoʻokele waiwai o ka hoʻohana ʻana i ka echelon.

Ke wikiwiki nei ke kūkulu ʻana i nā kahua kahua 5G, e piʻi nui ka koi no ka mālama ʻana i ka ikehu lithium. Ua hoʻolaha nui ʻo China Tower i ka hoʻohana ʻana i nā pihi mana a ua hoʻōki i ke kūʻai ʻana i nā pākī lead-acid.

ʻO ka lua, no ka mea e koi ana nā kahua kahua 5G i kahi hoʻolālā kiʻekiʻe, ʻo ka hale, a me nā wahi ʻē aʻe i kaupalena ʻia ka hiki ke halihali. I ka manawa like, i ka manawa e komo ai nā ʻeke uila 5G i ka kahiki kiʻekiʻe a me ka hōʻemi ʻana i ke kumukūʻai, e hoʻonui nui ʻia ka helu o ka hoʻouka ʻana a me ka hoʻokuʻu ʻana, a ʻo ka pōmaikaʻi o ke kumukūʻai haʻahaʻa holoʻokoʻa haʻahaʻa. likiuma hao phosphate iuo aaoa ?. e hiki ke pāʻani, i ka mea i hoʻomaha ʻia ka mana lithium ua lawe mai i nā manawa koʻikoʻi.

Aia kahi koi nui no ka mālama ʻana i ka ikehu lithium i loko o nā kahua kahua hale kiaʻi, e like me nā hiʻohiʻona o ka hoʻohana nui ʻana o nā ʻāpana tiered. E lilo lākou i wahi hoʻohana nui o nā ʻano pila; inā hoʻololi ʻia nā ʻōlima waihona ikehu o ke kahua kamaʻilio hale kiaʻi, a hoʻohana nā keʻena hou i nā ʻona cascade cascade, e ʻoki ʻia lākou i ka makahiki 2020. Hiki ke hoʻopaʻa ʻia ka pā uila ma mua o 80%.

Hōʻuluʻulu manaʻo: Ke hoʻohana nei ʻo China Tower i nā pā lithium e hoʻololi ai i nā pākī lead-acid, e hoʻopiha ana i nā āpau i nā kikoʻī loea no ka hoʻohana ʻana i ka cascading i ka ʻoihana kamaʻilio kūloko a me ka holomua ʻana i ka ʻenehana hoʻohana cascading.
