Malinga ndi nkhani yomwe inatulutsidwa ndi Electronic Information Department of the Ministry of Industry and Information Technology pa December 10, pofuna kulimbikitsanso kasamalidwe ka makampani a batire a lithiamu-ion ndikulimbikitsa kusintha ndi kukweza kwa mafakitale ndi kupita patsogolo kwaukadaulo, Unduna wa Zamakampani ndi Ukadaulo Waumisiri Waumisiri wawongolera kwakanthawi za "Lithium-ion Battery Specification Conditions" ndi "Lithium-ion Battery Industry Specification Announcement Management" Njirazo zawunikiridwa ndipo zalengezedwa.The "Lithium-ion Battery Specification Conditions (2018 Edition)" ndi "Interim Measures for Administration of Lithium-ion Battery Specification Announcements (2018 Edition)" (Chilengezo No. 5, 2019 cha Unduna wa Zamakampani ndi Ukadaulo Wachidziwitso ) zidzachotsedwa nthawi yomweyo.
"Lithium-ion batteries standard standard standards (2021)" ikufuna kuwongolera makampani kuti achepetse ntchito zopanga zomwe zimangokulitsa luso lopanga, kulimbikitsa luso laukadaulo, kuwongolera zinthu, komanso kuchepetsa ndalama zopangira.Makampani a batire a Lithium-ion ayenera kukwaniritsa izi: ku People's Republic of China olembetsedwa mwalamulo ndikukhazikitsidwa mdziko muno, okhala ndi umunthu wodziyimira pawokha;kupanga odziyimira pawokha, kugulitsa ndi kuthekera kwautumiki pazinthu zokhudzana ndi malonda a batri a lithiamu-ion;Ndalama za R&D sizochepera pa 3% ya ndalama zomwe kampani imapeza pachaka, ndipo makampani akulimbikitsidwa kupeza mabungwe odziyimira pawokha a R&D pamlingo wachigawo kapena pamwamba paziyeneretso za malo aukadaulo kapena mabizinesi apamwamba;zinthu zazikuluzikulu zili ndi ma patent opanga luso;zotsatira zenizeni za chaka cham'mbuyo pa nthawi yolengeza sizidzakhala zosachepera 50% za mphamvu zenizeni zopangira chaka chomwecho.
"Lithium-ion batteries standard standard standards (2021)" imafunanso kuti makampani atsatire ukadaulo wapamwamba, wopulumutsa mphamvu, wokonda zachilengedwe, wotetezeka komanso wokhazikika, komanso wanzeru kwambiri kupanga ndi zida, ndikukwaniritsa zofunikira izi: 1. Lithium-ion makampani batire ayenera kukhala ndi Kutha kuwunika kufanana kwa elekitirodi pambuyo ❖ kuyanika, ndi kulondola kulamulira ma elekitirodi ❖ kuyanika makulidwe ndi kutalika si zosakwana 2μm ndi 1mm motero;iyenera kukhala ndi ukadaulo woyanika ma elekitirodi, ndipo kulondola kwamadzi owongolera sikuyenera kukhala kuchepera 10ppm.2. Makampani a batri a lithiamu-ion ayenera kukhala ndi mphamvu zowongolera chilengedwe monga kutentha, chinyezi ndi ukhondo panthawi ya jekeseni;Ayenera kukhala ndi luso lozindikira ma test high-voltage high-circuit (HI-POT) pa intaneti pambuyo pa kusonkhana kwa batri.3. Mabizinesi onyamula batire a lithiamu-ion ayenera kukhala ndi mphamvu yowongolera voteji yotseguka ndi kukana kwamkati kwa maselo amodzi, ndipo kuwongolera kulondola sikuyenera kukhala kosachepera 1mV ndi 1mΩ motsatana;ayenera kukhala ndi luso loyang'ana ntchito ya bolodi yoteteza batire pa intaneti.
Pankhani ya magwiridwe antchito, "Lithium-ion Battery Viwanda Specification Conditions (2021 Edition)" yapanga izi:
(1) Mabatire ndi mapaketi a batri
1. Kachulukidwe ka mphamvu ya batire ya ogula ≥230Wh/kg, kachulukidwe ka batire ≥180Wh/kg, kachulukidwe ka batire imodzi ya polima ≥500Wh/L.Moyo wozungulira ndi ≥500 nthawi ndipo mphamvu yosungira mphamvu ndi ≥80%.
2. Mabatire amtundu wa mphamvu amagawidwa kukhala mtundu wa mphamvu ndi mtundu wa mphamvu.Pakati pawo, kachulukidwe ka mphamvu ya batri imodzi yamphamvu yogwiritsa ntchito zida za ternary ndi ≥210Wh/kg, kachulukidwe kake ka batire paketi ndi ≥150Wh/kg;kuchulukitsitsa kwa mphamvu zama cell ena amphamvu ndi ≥160Wh/kg, ndipo mphamvu ya batire paketi ndi ≥115Wh/kg.Kuchulukana kwamphamvu kwa batire imodzi yamphamvu ndi ≥500W/kg, ndipo kachulukidwe ka mphamvu ya batire la paketi ndi ≥350W/kg.Moyo wozungulira ndi ≥1000 nthawi ndipo mphamvu yosungira mphamvu ndi ≥80%.
3. Kuchulukitsitsa kwa mphamvu yamtundu wa batire imodzi yosungiramo mphamvu ndi ≥145Wh/kg, ndipo mphamvu ya batire paketi ndi ≥100Wh/kg.Mzunguliro moyo ≥ 5000 nthawi ndi mphamvu posungira mlingo ≥ 80%.
(2) Zinthu za Cathode
Mphamvu yeniyeni ya lithiamu iron phosphate ndi ≥145Ah/kg, mphamvu yeniyeni ya zida za ternary ndi ≥165Ah/kg, mphamvu yeniyeni ya lithiamu cobaltate ndi ≥160Ah/kg, ndipo mphamvu yeniyeni ya lithiamu manganenate ndi ≥115Ah/kg.Pazizindikiro zina zamachitidwe a cathode, chonde onani zomwe zili pamwambapa.
(3) Zinthu za Anode
Mphamvu yeniyeni ya carbon (graphite) ndi ≥335Ah/kg, mphamvu yeniyeni ya carbon amorphous ndi ≥250Ah/kg, ndipo mphamvu yeniyeni ya silicon-carbon ndi ≥420Ah/kg.Pazizindikiro zina zoyipa zama electrode, chonde onani zomwe zili pamwambapa.
