[Ngwa Coke] Nyocha ọkọnọ na mkpa na njirimara mmepe nke ngwa coke na China
I. Ike ahịa coke nke China
Na 2016, ikike mmepụta zuru ụwa ọnụ nke coke agịga bụ tọn 1.07 nde kwa afọ, ikike mmepụta nke coke agịga nke China bụ tọn 350,000 kwa afọ, nke ruru pasent 32.71 nke ikike mmepụta zuru ụwa ọnụ. Ka ọ na-erule 2021, ikike mmepụta zuru ụwa ọnụ nke coke agịga mụbara ruo tọn nde 3.36 kwa afọ, nke otu n'ime ikike mmepụta nke coke agịga nke China bụ tọn nde 2.29 kwa afọ, nke ruru pasent 68.15 nke ikike mmepụta zuru ụwa ọnụ. Ụlọ ọrụ mmepụta nke coke agịga nke China mụbara ruo 22. Ikike mmepụta zuru oke nke ụlọ ọrụ coke agịga nke ụlọ mụbara site na 554.29% ma e jiri ya tụnyere 2016, ebe ikike mmepụta nke coke agịga mba ọzọ kwụsiri ike. Ka ọ na-erule afọ 2022, ikike mmepụta nke agịga coke nke China amụbaala ruo tọn nde 2.72, mmụba nke ihe dị ka ugboro 7.7, ọnụọgụgụ ndị na-emepụta agịga coke nke China amụbaala ruo 27, na-egosi mmepe buru ibu nke ụlọ ọrụ ahụ, ma na-ele anya n'ụwa niile, oke nke agịga coke nke China na ahịa mba ụwa amụbaala kwa afọ.
1. Ike mmepụta mmanụ nke coke agịga
Ike mmepụta nke coke agịga nke usoro mmanụ malitere ito ngwa ngwa site na 2019. Site na 2017 ruo 2019, ahịa coke agịga nke usoro mmanụ na China bụ nke a na-eji atụ coal, ebe mmepe nke coke agịga nke usoro mmanụ adịghị nwayọ. Ọtụtụ n'ime ụlọ ọrụ ndị e guzobere ugbu a na-emepụta ihe mgbe 2018 gasịrị, ikike mmepụta nke coke agịga nke usoro mmanụ na China ruru tọn nde 1.59 ka ọ na-erule 2022. Mmepụta ahụ nọgidere na-amụba kwa afọ. Na 2019, ahịa elektrọd graphite nke dị n'okpuru ala gbanwere nke ukwuu, ọchịchọ maka coke agịga adịghịkwa ike. Na 2022, n'ihi mmetụta nke ọrịa COVID-19 na Olimpiks Oge Oyi na ihe omume ọha na eze ndị ọzọ, ọchịchọ ebelatala, ebe ọnụ ahịa dị elu, ụlọ ọrụ anaghị enwe mkpali imepụta ihe, uto mmepụta adịghịkwa nwayọ.
2. Ike mmepụta nke coal ntụtụ agịga coal
Ike mmepụta nke coal needle coke na-abawanye kwa afọ, site na tọn 350,000 na 2017 ruo tọn nde 1.2 na 2022. Site na 2020, òkè ahịa nke coal needle belatara, coke needle usoro mmanụ aghọọkwa isi ihe dị na agịga coke. N'ihe gbasara mmepụta, ọ nọgidere na-eto site na 2017 ruo 2019. Site na 2020, n'otu aka, ọnụ ahịa ya dị elu ma uru ya agbanwee. N'aka nke ọzọ, ọchịchọ maka electrode graphite adịghị mma.
Ⅱ. Nyocha ọchịchọ nke agịga Coke na China
1. Nyocha ahịa nke ihe lithium anode
Site na mmepụta ihe na-adịghị mma, mmepụta kwa afọ nke ihe na-adịghị mma nke China mụbara nke ukwuu site na 2017 ruo 2019. Na 2020, nke mmụba na-aga n'ihu nke ahịa njedebe ala metụtara, mmalite nke batrị ike na-amalite ịmalite, ọchịchọ ahịa na-abawanye nke ukwuu, usoro nke ụlọ ọrụ ihe na-adịghị mma na-abawanye, mmalite zuru oke nke ụlọ ọrụ na-amalite ngwa ngwa ma na-eme ka mmụba dịkwuo elu. Na 2021-2022, mmepụta ihe lithium cathode nke China gosipụtara uto dị egwu, na-erite uru site na mmezi na-aga n'ihu nke ọnọdụ azụmaahịa nke ụlọ ọrụ ndị dị n'okpuru ala, mmepe ngwa ngwa nke ahịa ụgbọ ala ike ọhụrụ, nchekwa ike, oriri, obere ike na ahịa ndị ọzọ gosikwara ọkwa dị iche iche nke uto, ụlọ ọrụ ihe cathode buru ibu na-anọgide na-emepụta ihe zuru oke. A na-eme atụmatụ na a na-atụ anya na mmepụta nke ihe electrode na-adịghị mma ga-agafe tọn nde 1.1 na 2022, ngwaahịa ahụ dịkwa n'ọnọdụ enweghị ọkọnọ, atụmanya ojiji nke ihe electrode na-adịghị mma sara mbara.
Needle coke bụ ụlọ ọrụ mmepụta ihe batrị lithium na ihe anode, nke nwere njikọ chiri anya na mmepe nke ahịa batrị lithium na ihe cathode. Ngalaba ojiji nke batrị lithium gụnyere batrị ike, batrị ndị ahịa na batrị nchekwa ike. Na 2021, batrị ike ga-abụ pasent 68, batrị ndị ahịa ga-abụ pasent 22, na batrị nchekwa ike maka pasent 10 nke nhazi ngwaahịa batrị lithium ion nke China.
Batrị ike bụ isi ihe dị mkpa n'ụgbọala ike ọhụrụ. N'afọ ndị na-adịbeghị anya, site na mmejuputa iwu "oke carbon, nke na-anọpụ iche na carbon", ụlọ ọrụ ụgbọ ala ike ọhụrụ nke China webatara ohere ọhụrụ n'akụkọ ihe mere eme. Na 2021, ire ụgbọ ala ike ọhụrụ zuru ụwa ọnụ ruru nde 6.5, mbupu batrị ike ruru 317GWh, mmụba 100.63% kwa afọ. Ahịa ụgbọ ala ike ọhụrụ nke China ruru nde 3.52, mbupu batrị ike ruru 226GWh, mmụba 182.50% kwa afọ. A na-atụ anya na mbupu batrị ike zuru ụwa ọnụ ga-eru 1,550GWh na 2025 na 3,000GWh na 2030. Ahịa China ga-anọgide na-enwe ọnọdụ ya dị ka ahịa batrị ike kachasị ukwuu n'ụwa yana òkè ahịa kwụsiri ike nke karịrị 50%.
