I-China Tower isebenzisa amabhethri e-lithium ukushintsha amabhethri e-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.

I-2020 Tower Communication Base Station izothatha indawo ka-600-700,000 Towers of Lithium Battery

Ukuhlomula ngokushintshwa kweziteshi zesisekelo sesitoko, indawo yemakethe ebanzi yokugcina amandla okuxhumana elethwe ukuthandwa okukhulu kweziteshi eziyisisekelo ze-5G, kanye nokudayiswa okusheshayo kokugcinwa kwamandla ohlangothini lokuphehla amandla, ohlangothini lwegridi, kanye nohlangothi lwabasebenzisi, imakethe yokugcina amandla ebhethri ye-lithium ikhula ngokushesha. Kusukela ekupheleni kukaJuni 2019, i-China Tower isithole izidingo zokwakha isisekelo sesiteshi se-65,000G ezingu-5, futhi kulindeleke ukuthi ithole izidingo zokwakhiwa kwesiteshi se-100,000G ezingu-5 kulo nyaka wonke.

1) Imakethe yebhethri lamandla: ukuthengiswa kwasekhaya kwezimoto zamandla amasha kulindeleke ukuthi kufinyelele ezigidini ezingu-7 ngo-2025, futhi ukuthengiswa kwamanye amazwe kulindeleke ukuthi kudlule izigidi eziyisi-6 ngo-2025. Ngo-2020, isidingo sebhethri lamandla asekhaya sizoba ngu-85GWh. Ngo-2020, isidingo sebhethri lamandla aphesheya sizoba ngu-90GWh. Isikhala semboni yebhethri lamandla siyaqhubeka nokukhula, futhi isidingo samabhethri kagesi kulindeleke ukuthi sikhule cishe ngama-50% ngo-2020.

2) Imakethe yebhethri elingenamandla: Imakethe yokugcina amandla ebhethri ye-lithium isanda kuqala. Ukushintshwa kwelead-asidi kwamabhethri e-lithium eziteshini eziyisisekelo zokuxhumana zombhoshongo kuyindawo yesidingo ebaluleke kakhulu. Ngo-2018, amabhethri e-lithium e-lead-acid e-China Tower athatha isamba semibhoshongo engu-120,000, esebenzisa cishe i-1.5GWh yamabhethri e-lithium. Kuzoshintshwa imibhoshongo eyizinkulungwane ezingamakhulu amathathu ngonyaka ka-2019, kusetshenziswa i-4-5GWh yamabhethri e-lithium, kanti izakhiwo ezingama-600,000-700,000 kulindeleke ukuthi zithathelwe indawo ngo-2020, okuhlelwe ukuthi zibe yi-8GWh. Yonke imibhoshongo izothathelwa indawo cishe ngu-25GWh, omkhulu kakhulu.

3) Asikho isidingo sokukhathazeka mayelana nokuqondisa okujwayelekile kwamabhethri e-lithium: kungakhathaliseki ukuthi izimoto zamandla amasha, amafoni omakhalekhukhwini angu-5G, amaphuzu okusekela esiteshini sesisekelo, namabhethri okugcina amandla, konke ukukhula okunqunyiwe nokuqhubekayo. Ngokuthuthukiswa kwe-inthanethi yeselula kanye ne-inthanethi Yakho Konke, kusukela kuzintambo kuya okungenantambo, amabhethri e-Lithium okwamanje ayizisombululo zamandla ezingcono kakhulu.

Isiphi isignali esithunyelwa umbhoshongo wensimbi lapho ushintsha amabhethri e-lead-asidi ngamabhethri e-lithium?

Njengenkampani enkulu yengqalasizinda yezokuxhumana ephethwe nguhulumeni, iTower Company ineziteshi eziyisisekelo eziyizigidi eziyi-1.9. Isikhathi eside, isisekelo sesiteshi sikagesi sase-China Tower Corporation Limited sisebenzisa amabhethri ane-asidi yomthofu, futhi unyaka ngamunye sithenga amathani angu-100,000 amabhethri ane-asidi yomthofu. Amabhethri e-lead-acid anempilo yesevisi emfushane, ukusebenza okuphansi, nomthofu wensimbi enzima. Uma zilahlwa, zizodala ukungcoliswa kwesibili kwemvelo uma zingaphathwa ngendlela efanele.

Kodwa-ke, uma kuqhathaniswa namabhethri e-lead-acid, amabhethri e-lithium anezinzuzo zokuminyana kwamandla aphezulu kanye nempilo ende yesevisi. Ngalesi sizathu, i-Tower Company yaqala ngo-2015 futhi yalandelana izivivinyo zokukhipha amabhethri e-lead-asidi namabhethri eziteshini eziyisisekelo ezingaphezu kuka-3000 ezifundazweni nasemadolobheni angu-12. Ukuphepha kanye nokuba nokwenzeka kwezobuchwepheshe nezomnotho kokusetshenziswa kwe-echelon kuyaqinisekiswa.

Njengoba ukwakhiwa kweziteshi eziyisisekelo ze-5G kuyashesha, isidingo sokugcina amandla amabhethri e-lithium nawo azokhula kakhulu. I-China Tower ikukhuthaze ngokuphelele ukusetshenziswa kwe-cascade yamabhethri wamandla futhi iyekile ukuthenga amabhethri e-lead-acid.

Okwesibili, ngenxa yokuthi iziteshi eziyisisekelo ze-5G zidinga ukwakheka okuphezulu, uphahla, nezinye izindawo zinomthamo olinganiselwe wokuthwala. Ngesikhathi esifanayo, lapho amabhethri okugcina amandla e-5G ebamba iqhaza ekushebeni okuphezulu nokunciphisa izindleko, inani lokushaja nokukhipha lizokwenyuka kakhulu, futhi inzuzo yezindleko eziphansi zomjikelezo ogcwele. amabhethri e-lithium iron phosphate kuzoba Ukukwazi ukudlala, kumandla asethathe umhlalaphansi ibhethri ye-lithium ilethe amathuba abaluleke kakhulu.

Kunesidingo esikhulu samabhethri e-lithium okugcina amandla eziteshini zesisekelo sombhoshongo, ahambisana nezici zokusetshenziswa okukhulu kwamabhethri anezigaba. Azoba yizindawo ezisetshenziswa kakhulu zamabhethri anezigaba; uma isisekelo sombhoshongo amabhethri okugcina amandla eshintshwa, futhi iziteshi ezintsha zonke zisebenzisa amabhethri ebhethri anamandla, Izowachitha ngo-2020. Ibhethri lamandla lingamunca ngaphezu kuka-80%.

Isifinyezo: I-China Tower isebenzisa amabhethri e-lithium ukuze imiselele amabhethri e-lead-asidi, igcwalisa izikhala ezincazelweni zobuchwepheshe zokusetshenziswa kwe-cascading embonini yezokuxhumana yasekhaya kanye nokuthuthukiswa kobuchwepheshe bokusebenzisa i-cascading.
