Fahimtar Hatsarin Fashewa na Batir Lithium-ion Polymer

Dangane da nau'in electrolyte da aka yi amfani da shi, ana rarraba batura lithium-ion zuwa batir lithium-ion batir (LIB) da batir lithium-ion polymer (PLB), wanda kuma aka sani da batir lithium-ion filastik.

PLBs suna amfani da anode iri ɗaya da kayan cathode azaman batir lithium-ion ruwa, gami da lithium cobalt oxide, lithium manganese oxide, kayan ternary, da lithium baƙin ƙarfe phosphate don cathode, da graphite ga anode. Bambanci na farko ya ta'allaka ne a cikin electrolyte da aka yi amfani da su: PLBs suna maye gurbin ruwa mai amfani da lantarki tare da ingantaccen polymer electrolyte, wanda zai iya zama ko dai "bushe" ko "kamar gel." Yawancin PLBs a halin yanzu suna amfani da polymer gel electrolyte.

Yanzu, tambaya ta taso: shin da gaske batir lithium-ion polymer suna fashe? Ganin ƙananan girmansu da nauyi mai nauyi, PLBs ana amfani dasu sosai a cikin kwamfyutocin kwamfyutoci, wayoyin hannu, da sauran kayan lantarki masu ɗaukar nauyi. Tare da waɗannan na'urori galibi ana ɗaukar su, amincin su shine mafi mahimmanci. Don haka, ta yaya amincin PLBs yake, kuma shin suna haifar da haɗarin fashewa?

1. PLBs suna amfani da gel-kamar electrolyte, dabam da na ruwa electrolyte a cikin batura lithium-ion. Wannan gel-kamar electrolyte ba ya tafasa ko samar da iskar gas mai yawa, ta yadda zai kawar da yiwuwar fashewar tashin hankali.
2. Batura lithium yawanci suna zuwa tare da allon kariya da layin hana fashewa don aminci. Koyaya, ana iya iyakance tasirin su a yanayi da yawa.
3. PLBs suna amfani da marufi mai sassauƙa na filastik aluminium, sabanin juzu'in ƙarfe na ƙwayoyin ruwa. A cikin lamuran tsaro, sun kan kumbura maimakon fashe.
4. PVDF, azaman kayan tsari don PLBs, yana aiki da kyau.

Kariyar Tsaro don PLBs:

• Short Circuit: Abubuwan da ke haifar da ciki ko na waje, galibi yayin caji. Rashin haɗin kai tsakanin faranti na baturi kuma na iya haifar da gajeriyar kewayawa. Kodayake yawancin batura lithium-ion suna zuwa tare da da'irori masu kariya da layin hana fashewa, waɗannan ƙila ba koyaushe suke tasiri ba.
• Yawan caji: Idan an caje PLB da ƙarfin lantarki mai tsayi na tsayi da yawa, zai iya haifar da zafi na ciki da haɓaka matsi, yana haifar da faɗaɗawa da fashewa. Yin caji mai yawa da zurfafa zurfafawa na iya lalata sinadarin baturin ba tare da jurewa ba, yana yin tasiri sosai ga tsawon rayuwarsa.

Lithium yana da ƙarfi sosai kuma yana iya kama wuta cikin sauƙi. Lokacin caji da fitarwa, ci gaba da dumama baturi da fadada iskar gas da ake samarwa na iya ƙara matsa lamba na ciki. Idan rumbun ya lalace, zai iya haifar da yoyo, wuta, ko ma fashewa. Koyaya, PLBs sun fi fashewa fiye da fashewa.

Amfanin PLBs:

1. Babban ƙarfin aiki a kowane tantanin halitta.
2. Babban iya aiki.
3. Karamin zubar da kai.
4. Dogon zagayowar rayuwa, sama da keke 500.
5. Babu tasirin ƙwaƙwalwar ajiya.
6. Kyakkyawan aikin aminci, ta amfani da marufi mai sassauƙa na filastik aluminum.
7. Matsananciyar bakin ciki, zai iya shiga cikin sarari masu girman katin kiredit.
8. Fuskar nauyi: Babu buƙatar tulin karfe.
9. Girman ƙarfi idan aka kwatanta da kwatankwacin girman batirin lithium.
10. Ƙananan juriya na ciki.
11. Kyakkyawan halayen fitarwa.
12. Ƙirar allon kariya mai sauƙi.

Lalacewar PLBs:

1. Babban farashin samarwa.
2. Bukatar kewayawar tsaro.
