Imvelaphi

Ekuqaleni kukaJulayi 2023, kwiseshoni ye-62 ye-United Nations Economic Subcommittee yeeNgcali zoThutho lweeMpahla ezinobungozi, i-Subcommittee iqinisekisile inkqubela phambili yomsebenzi eyenziwa yiQela eliSebenzayo eliNgenasesikweni (IWG) kwinkqubo yokuhlelwa kweengozi kwiiseli ze-lithium kunye neebhetri. , kwaye uvumelene nophononongo lwe-IWG lweUYilo lwemigaqokwaye uhlaziye kwakhona ulwahlulo lwengozi lwe "Model" kunye neprotocol yovavanyo lweIncwadi yoVavanyo kunye neekhrayitheriya.

Okwangoku, siyazi kumaxwebhu akutshanje okusebenza kwiseshoni ye-64 ukuba i-IWG ingenise idrafti ehlaziyiweyo yenkqubo yokuhlelwa kwe-lithium yebhetri yengozi (ST/SG/AC.10/C.3/2024/13). Intlanganiso iya kubanjwa ukususela ngomhla wama-24 kuJuni ukuya kowe-3 kaJulayi, 2024, xa ikomitana iza kuphonononga uyilo.

Uhlaziyo oluphambili kuhlelo oluyingozi lweebhetri ze-lithium lulandelayo:

Imigaqo

Yongeziwe ukuhlelwa kweengozikwayeInombolo ye-UNkwiiseli ze-lithium kunye neebhetri, iiseli ze-sodium ion kunye neebhetri

Imeko yebhetri ngexesha lothutho kufuneka imiselwe ngokweemfuno zodidi lobungozi ekulo;

Lungisa amalungiselelo akhethekileyo 188, 230, 310, 328, 363, 377, 387, 388, 389, 390;

Kongezwe uhlobo olutsha lokupakisha: PXXX kunye nePXXY;

Incwadi yoVavanyo kunye neMigangatho

Iimfuno zovavanyo ezongeziweyo kunye neetshati zohlelo lokuhamba ezifunekayo kuhlelo lweengozi;

Izinto zovavanyo ezongezelelweyo:

T.9: Uvavanyo lokusasazwa kweeseli

T.10: Ukumiselwa komthamo werhasi yeseli

T.11: Uvavanyo lokusasaza ibhetri

T.12: Ukumiselwa komthamo wegesi yebhetri

T.13: Ukumisela ukutsha kwerhasi yeseli

Eli nqaku lizakwazisa ulwahlulo olutsha lwengozi yebhetri kunye nezinto zovavanyo ezongeziweyo kwidrafti.

Ukwahlula ngokweendidi zengozi

Iiseli kunye neebhetri zinikezelwe kwelinye lamacandelo ngokweempawu zabo ezinobungozi njengoko kuchazwe kwitheyibhile elandelayo. Iiseli kunye neebhetri zabelwe icandelo elihambelana neziphumo zeemvavanyo ezichazwe kwiIncwadi yoVavanyo kunye neekhrayitheriya, inxalenye III, icandelwana 38.3.5 kunye 38.3.6.

Iiseli zeLithium kunye neebhetri

Iibhetri ze-sodium ion

Iiseli kunye neebhetri ezingavavanywanga ngokwe-38.3.5 kunye ne-38.3.6, kubandakanywa iiseli kunye neebhetri eziziiprototypes okanye imveliso ephantsi iqhuba, njengoko kukhankanyiwe kwilungiselelo elikhethekileyo le-310, okanye iiseli ezonakalisiweyo okanye ezineziphene kunye neebhetri zinikezelwa kwikhowudi yokuhlelwa kwe-95X.

Izinto zovavanyo

Ukumisela ulwahlulo oluthile lweseli okanye ibhetri,3 uphindaphindoyovavanyo olungqamene neflowutshati yokwahlulahlula iya kuqhutywa. Ukuba olunye lweemvavanyo alunakugqitywa kwaye lwenza ukuba uvavanyo lwengozi lungenzeki, iimvavanyo ezongezelelweyo ziya kuqhutywa, kude kugqitywe iimvavanyo ezi-3 ezisebenzayo. Eyona ngozi inzima kakhulu elinganiswe kwiimvavanyo ezi-3 ezisebenzayo ziya kuxelwa njengeseli okanye iziphumo zovavanyo lwebhetri. .

Ezi zinto zilandelayo zovavanyo kufuneka zenziwe ukumisela ulwahlulo oluthile lweseli okanye ibhetri:

T.9: Uvavanyo lokusasazwa kweeseli

T.10: Ukumiselwa komthamo werhasi yeseli

T.11: Uvavanyo lokusasaza ibhetri

T.12: Ukumiselwa komthamo wegesi yebhetri

T.13: Ukuzimisela ukutsha kwerhasi yeseli (Ayizizo zonke iibhetri ze-lithium ezibonisa ingozi yokutsha. Uvavanyo lokufumanisa ukutsha kwerhasi lukhetho lolwahlulo 94B, 95B okanye 94C kunye 95C. Ukuba uvavanyo alwenziwanga ke ulwahlulo 94B okanye 95B lucingelwa ngu ukusilela.)

Isishwankathelo

Ukuhlaziywa kokuhlelwa kwengozi yeebhetri ze-lithium kubandakanya umxholo omningi, kwaye iimvavanyo ezi-5 ezintsha ezinxulumene nokubaleka kwe-thermal zongeziwe. Kuqikelelwa ukuba akunakwenzeka ukuba zonke ezi mfuno zintsha ziya kudlula, kodwa kusacetyiswa ukuba ziqwalaselwe kwangaphambili kuyilo lwemveliso ukuphepha ukuchaphazela umjikelezo wophuhliso lwemveliso emva kokuba zidlule.
