Kumvetsetsa Chiwopsezo Chophulika cha Mabatire a Polymer Lithium-Ion

Kutengera mtundu wa ma electrolyte omwe amagwiritsidwa ntchito, mabatire a lithiamu-ion amagawidwa kukhala mabatire a lithiamu-ion (LIB) ndi ma polymer lithiamu-ion mabatire (PLB), omwe amadziwikanso kuti mabatire a pulasitiki a lithiamu-ion.

PLBs amagwiritsa ntchito zinthu zomwezo za anode ndi cathode monga mabatire a lithiamu-ion, kuphatikizapo lithiamu cobalt oxide, lithiamu manganese oxide, ternary materials, ndi lithiamu iron phosphate kwa cathode, ndi graphite ya anode. Kusiyana kwakukulu kuli mu electrolyte yogwiritsidwa ntchito: PLBs m'malo mwa electrolyte yamadzimadzi ndi electrolyte yolimba ya polima, yomwe ingakhale "yowuma" kapena "gel-like." Ma PLB ambiri pakali pano amagwiritsa ntchito polima gel electrolyte.

Tsopano, funso likubuka: kodi mabatire a lithiamu-ion polymer amaphulikadi? Chifukwa cha kukula kwawo kochepa komanso kulemera kwake, ma PLB amagwiritsidwa ntchito kwambiri m'ma laputopu, mafoni a m'manja, ndi zipangizo zina zamagetsi. Ndi zida izi nthawi zambiri zimayendetsedwa mozungulira, chitetezo chawo ndichofunika kwambiri. Kotero, chitetezo cha PLB ndi chodalirika chotani, ndipo kodi chimayambitsa kuphulika?

1. Ma PLB amagwiritsa ntchito gel-ngati electrolyte, yosiyana ndi electrolyte yamadzimadzi m'mabatire a lithiamu-ion. Electrolyte yonga gel iyi siwirikiza kapena kutulutsa mpweya wambiri, motero imachotsa kuthekera kwa kuphulika kwamphamvu.
2. Mabatire a lithiamu nthawi zambiri amabwera ndi bolodi lachitetezo ndi mzere wotsutsa kuphulika kwa chitetezo. Komabe, kuchita bwino kwawo kungakhale kochepa muzochitika zambiri.
3. Ma PLB amagwiritsa ntchito ma pulasitiki a aluminiyamu osinthika, mosiyana ndi zitsulo zachitsulo zama cell amadzimadzi. Pankhani yachitetezo, amakonda kutupa m'malo mophulika.
4. PVDF, monga chimango cha PLBs, imagwira ntchito bwino kwambiri.

Chitetezo cha PLBs:

• Kuzungulira Kwachidule: Kumachitika ndi zinthu zamkati kapena zakunja, nthawi zambiri pakulipiritsa. Kusagwirizana koyipa pakati pa mbale za batri kungayambitsenso mabwalo afupikitsa. Ngakhale mabatire ambiri a lithiamu-ion amabwera ndi mabwalo oteteza komanso mizere yotsutsa kuphulika, izi sizingakhale zothandiza nthawi zonse.
• Kuchulukirachulukira: Ngati PLB ili ndi magetsi okwera kwambiri kwa nthawi yayitali, imatha kuyambitsa kutenthedwa kwamkati ndikumangirira, zomwe zimapangitsa kukula ndi kuphulika. Kuchucha mochulukira ndi kuthira mozama kungathenso kuwononga mankhwala a batire mosasinthika, kusokoneza kwambiri moyo wake.

Lithium imagwira ntchito kwambiri ndipo imatha kugwira moto mosavuta. Pa kulipiritsa ndi kutulutsa, kutentha kosalekeza kwa batire ndi kukulitsa kwa mpweya wopangidwa kungapangitse kupanikizika kwamkati. Ngati chosungiracho chawonongeka, chingayambitse kutayikira, moto, kapena kuphulika. Komabe, ma PLB amatha kutupa kuposa kuphulika.

Ubwino wa PLBs:

1. Mphamvu yogwira ntchito kwambiri pa selo.
2. Kuchulukana kwakukulu.
3. Kudziletsa pang'ono.
4. Moyo wautali wozungulira, wopitilira 500.
5. Palibe kukumbukira.
6. Kuchita bwino kwachitetezo, pogwiritsa ntchito ma aluminium pulasitiki osinthika ma CD.
7. Zoonda kwambiri, zimatha kulowa m'malo akulu akulu a kirediti kadi.
8. Opepuka: Palibe chifukwa choyika zitsulo.
9. Kuchuluka kwakukulu poyerekeza ndi mabatire a lithiamu ofanana.
10. Kukana kwamkati kochepa.
11. Makhalidwe abwino otaya.
12. Mapangidwe a board achitetezo osavuta.

Kuipa kwa PLBs:

1. Mtengo wapamwamba wopanga.
2. Kufunika kwa chitetezo chamthupi.
