Background

Kubva muna Chikunguru 2023, pamusangano wechimakumi matanhatu nembiri weUnited Nations Economic Subcommittee yeNyanzvi pamusoro pekutakurwa kwezvinhu zvine ngozi, Subcommittee yakasimbisa kufambira mberi kwebasa kwakaitwa neInformal Working Group (IWG) panjodzi yekuisa hurongwa hwemaseru e lithium nemabhatiri. , uye yakabvumirana nekuongorora kweIWG kweRegulations Draftuye ongorora kurongeka kwengozi ye "Model" uye test protocol yeBhuku reMiedzo uye Mamiriro.

Parizvino, tinoziva kubva kumagwaro ekupedzisira ekushanda kwechikamu che64 kuti IWG yakatumira dhizaini yakadzokororwa ye lithium battery hazard classification system (ST/SG/AC.10/C.3/2024/13). Musangano uchaitwa kubva muna Chikumi 24 kusvika Chikunguru 3, 2024, apo komiti diki ichaongorora gwaro.

Iwo makuru ekudzokororwa kune njodzi classification yelithium mabhatiri ndeaya anotevera:

Regulations

Added njodzi classificationuyeNhamba yeUNye lithium masero nemabhatiri, sodium ion masero uye mabhatiri

Mamiriro ekuchajisa kwebhatiri panguva yekufambisa kunofanirwa kutariswa zvinoenderana nezvinodiwa zvechikamu chengozi kwairi;

Shandura zvirongwa zvakakosha 188, 230, 310, 328, 363, 377, 387, 388, 389, 390;

Yakawedzera mhando nyowani yekurongedza: PXXX uye PXXY;

Bhuku reMiedzo neMitemo

Yakawedzerwa bvunzo zvinodiwa uye kupatsanurwa kuyerera machati anodiwa pachikamu chenjodzi;

Zvimwe bvunzo zvinhu:

T.9: Muedzo wekuparadzira masero

T.10: Cell gasi vhoriyamu kutsunga

T.11: Battery propagation test

T.12: Battery gasi vhoriyamu kutsunga

T.13: Sero gasi rinopisa kutsunga

Chinyorwa ichi chichasuma iyo nyowani yengozi yebhatiri kupatsanurwa uye yekuyedza zvinhu zvakawedzerwa mugwaro.

Kukamukana zvichienderana nezvikamu zvengozi

Masero nemabhatiri anopihwa kune imwe yezvikamu zvinoenderana neayo njodzi zvivakwa sezvinotsanangurwa patafura inotevera. Masero nemabhatiri anopihwa kuchikamu chinowirirana nemhedzisiro yebvunzo dzakatsanangurwa muBhuku reMiedzo uye Mamiriro, chikamu III, chikamu chiduku 38.3.5 uye 38.3.6.

Lithium masero uye mabhatiri

Sodium ion mabhatiri

Masero nemabhatiri asina kuedzwa maererano ne38.3.5 uye 38.3.6, kusanganisira maseru nemabhatiri ari prototypes kana yakaderera zvigadzirwa zvinomhanya, sezvakataurwa mune yakakosha kupihwa 310, kana akakuvadzwa kana akaremara maseru nemabhatiri anopihwa kodhi kodhi 95X.

Test Items

Kuti uone kupatsanurwa kwesero kana bhatiri,3 dzokororoyebvunzo inoenderana nechikamu chekuyerera ichaitwa. Kana imwe yezviedzo isingakwanisi kupedzwa uye ichiita kuti kuongororwa kwengozi kusagoneke, mimwe miedzo ichaitwa, kusvikira chiyero che 3 chekuongorora chechokwadi chapera.Njodzi yakakomba yakayerwa pamusoro pemiyedzo ye3 inoshanda ichataurwa sesero kana bhatiri mhinduro yekuedza. .

Izvi zvinotevera bvunzo zvinhu zvinofanirwa kuitwa kuti zvionekwe yakatarwa sero kana bhatiri:

T.9: Muedzo wekuparadzira masero

T.10: Cell gasi vhoriyamu kutsunga

T.11: Battery propagation test

T.12: Battery gasi vhoriyamu kutsunga

T.13: Cell gas flammability determination (Haasi ose mabhatiri eLithium anoratidza njodzi yekupisa. Kuedza kuona kuti gasi rinobvira moto nderokusarudza kuti ripiwe chero zvikamu 94B, 95B kana 94C uye 95C. Kana kuedza kukasaitwa ipapo zvikamu 94B kana 95B zvinofungidzirwa ne default.)

Summary

Iko kudzokororwa kweiyo njodzi kukamurwa kwemabhatiri e-lithium kunosanganisira zvakawanda zvemukati, uye 5 mitsva mitsva ine chekuita nekupisa kwekupisa kwakawedzerwa. Zvinofungidzirwa kuti hazvigoneke kuti zvese izvi zvitsva zvinodiwa zvichapfuura, asi zvichiri kukurudzirwa kuti uzvifungire pachine nguva mukugadzirwa kwechigadzirwa kudzivirira kukanganisa kutenderera kwechigadzirwa kana vapfuura.
