Muva nje, uMnyango Wezokuthutha wase-US'I-Pipeline and Hazardous Materials Safety Administration (PHMSA) ikhiphe inguqulo ka-2024 ye-”Umhlahlandlela Wezimpendulo Eziphuthumayo”. Umhlahlandlela uhlanganisa izinto ezihlukahlukene eziyingozi, izindlela eziphuthumayo ezihambisanayo kanye nezinyathelo zokuphepha, okuhloswe ngazo ukusiza nokuqondisa abatakuli emisebenzini yabo ekutakuleni izimo eziphuthumayo zomlilo ezihlosiwe. Uma kuqhathaniswa nenguqulo ka-2020, inguqulo entsha yomhlahlandlela inezinguquko ezibalulekile ezilandelayo kokuqukethwe kwebhethri ye-lithium:

lIzexwayiso ezingeziwe mayelana nebhethri ye-lithium nemililo yemoto kagesi, okuhlanganisa ukuhlonza amabhethri e-lithium awonakele, angalungile noma akhunjulwayo. (amabhethri e-DDR).

Ibhethri ye-Lithium kanye nokulawula umlilo wemoto kagesi

1. Isifutho samanzi sipholisa amabhethri futhi sisize ukucindezela kanye nokubambezela ukuphuma kwamagesi anobuthi kodwa asikuvimbi ukusabela kwamakhemikhali (i-thermal runaway). Ezinye izinto zokucima umlilo (i-CO, ikhemikhali eyomile, njll.) zingabamba ukushisa esikhundleni sokukususa futhi zingaholela ekufundweni okungamanga (izinga lokushisa eliphansi).
2. Ngesikhathi somlilo wemoto kagesi (i-EV), thintana nomhlahlandlela othize wokuphendula izimo eziphuthumayo womkhiqizi ukuze uthole usizo lokuhlonza amakhebhula kagesi aphezulu kanye naphakathi. UNGAWASIKI LAMAKHEBU.
3. Izimoto zikagesi eziningi zinezihibe ezisikiwe eziphuthumayo okungamalupu ezintambo ezinama-voltage aphansi anganqanyulwa ukuze kunqanyulwe uhlelo lwamandla kagesi aphezulu kuyo yonke imoto. Uma kuphephile ukwenza kanjalo, landela iziqondiso zomkhiqizi ukuze unqamule ibhethri elingu-12-volt. Lokhu kuzohlukanisa amandla ebhethri lamandla kagesi aphezulu futhi kunciphise ingozi yokushaqeka kukagesi.

AMABHHTHARI ALI-LITHIMU ONAKILE, AYIQINISEKILE, NOMA AKHUMBULE

Wonke amabhethri e-lithium angabangela ingozi yomlilo, kungakhathaliseki ukuthi iyinsimbi ye-lithium noma i-lithium ion, entsha noma esetshenzisiwe. Nokho, konakele, enesici, noma ekhumbuliwe (DDR) amabhethri e-lithium abeka engcupheni enkulu kunengeyona i-DDR amabhethri e-lithium ngoba maningi amathuba okuthi abambe umlilo ngenqubo eyaziwa ngokuthi as“ukubaleka okushisayo”. I-Thermal Runaway ukusabela kweketango okuholela ekukhishweni okunodlame kwamandla agciniwe kanye negesi evuthayo. Lokhu kusabela kungasakazekela kwamanye amabhethri noma izinto ezivuthayo eziseduze, ezingaholela esenzakalweni esikhulu sokushisa esinemiphumela emibi.

Izimpawu zokuthi ibhethri lonakele, linesici, noma libuyisiwe zifaka phakathi:

a,Lukudla ama-electrolyte

b,Sisikhwama sebhethri esiwohlokile noma esishintshile

c,Oi-dor noma ukugqwala

d,Bama-urn marks

e,Kizimo zamanje zokusetshenziswa noma ukusetshenziswa kabi

f,Bwakhumbula

• Umhlahlandlela No.147 Umhlahlandlela Wokulawula Umlilo webhethri ye-lithium-ion usubuyekeziwe, futhi impendulo Ephuthumayo yomlilo webhethri ye-sodium-ion kanye nesiqondiso mayelana nemililo yemoto kagesi yengeziwe.
