Kodi mabatire a polima amalimbana ndi kutentha kochepa?

Mabatire a polima amapangidwa makamaka ndi zitsulo zachitsulo (ITO) ndi ma polima (La Motion). Mabatire a polima nthawi zambiri safupika ngati kutentha kwa selo kuli pansi pa 5°C. Komabe, pali mavuto ena mukamagwiritsa ntchito mabatire a polima pa kutentha kochepa chifukwa sagonjetsedwa ndi kusintha kwa kutentha, kotero anthu ambiri sadziwa momwe angatetezere mabatire a polima. Ndipotu, ma capacitor ambiri apulasitiki amatha kugwiritsidwa ntchito pakati pa -40 ° C ndi 85 ° C monga kutentha kwabwino. Mabatire ambiri a polima amathanso kugwiritsidwa ntchito pansi pa -60 ° C. Izi ndichifukwa choti zitha kupangidwa pogwiritsa ntchito njira zopangira ndi njira zofanana ndi zomwe zimagwiritsidwa ntchito pamtundu uliwonse wa batri.

Ntchito yayikulu yamabatire a polima

Batire ya polima ndi mtundu watsopano wa batri ya lithiamu-ion, yomwe imagwiritsa ntchito mfundo zazikulu za zinthu za polima zomwe zimakhala ndi ma elekitirodi abwino komanso oipa, omwe ali ndi magawo atatu: electrode yabwino, electrode negative ndi diaphragm. Elekitirodi zabwino: kamangidwe kabwino elekitirodi wa polima zipangizo wapangidwa awiri mogwirizana perpendicular m'munsi mmwamba otsetsereka hexagon kapena hexahedron; elekitirodi negative: ma elekitirodi negative kapangidwe polima zipangizo wapangidwa ndi sikisi ofanana hexagon kapena hexahedron olumikizidwa pamodzi; diaphragm: zida za polima zimakhala ndi zida zosiyanasiyana za diaphragm, kuphatikiza ma ayoni achitsulo, ma oxide achitsulo, ma oxide achitsulo omwe si amtengo wapatali, zida zoteteza ndi ma oxides ndi mitundu ina yambiri. Popeza ma elekitirodi olakwika nthawi zambiri amagwiritsa ntchito zida za polima, amafanana ndi batire yamtundu uliwonse. Mabatirewa amatha kugwiritsidwa ntchito kwambiri popangira mphamvu kapena kulipiritsa zida zamagetsi monga mafoni a m'manja, zida zamagetsi zam'manja, ndi makompyuta apakompyuta. Mabatire a polima opangidwa kuchokera ku zinthu za polima amakhala ndi magwiridwe antchito apamwamba kwambiri pakutentha kotsika.

Wamba polima batire mankhwala ndi makhalidwe awo

Maselo a 1.Polymer: amatanthauza kugwiritsa ntchito zipangizo za polima, zipangizo za polima ndi zipangizo za polima, zochokera kuzinthu zosiyana siyana, kupyolera mu maselo a polima angagwiritsidwe ntchito m'njira zosiyanasiyana.
Ma cell a 2.Ppolymer: amatanthauza kugwiritsa ntchito mabatire a polima a lithiamu-ion, ndi zida zopangira polima mu microcontrollers, zida zamagalimoto ndi zida zolumikizirana opanda zingwe zimagwiritsidwa ntchito kwambiri, nthawi zambiri zimagwiritsidwa ntchito mu nickel-cadmium, faifi tambala-zitsulo hydride ndi zina. mabatire achitsulo oksidi ndi mabatire a lithiamu-ion.
Ma cell a 3.Polymer: amatanthawuza zitsulo za oxide monga pachimake, ndi zida za polima monga mphamvu ndi kutulutsa thupi, zomwe zimagwiritsidwa ntchito mu electrolyte ya lithiamu-ion batire ya polima ndipo imagwiritsidwa ntchito kwambiri pamafoni anzeru, makompyuta am'manja, zida zamagetsi ndi zida zina zambiri zamagetsi. .
Maselo a 4.Polymer: ndiye kuti, zinthu za polima monga maziko opangira selo, nthawi zambiri zimagawidwa m'maselo wamba, maselo amtundu wambiri komanso maselo a hyperpolarized polima maselo amtundu wambiri, omwe ali ndi resistivity yabwino, katundu wabwino wa electrochemical. , ntchito yabwino yotetezera komanso kutsika mtengo ndi kutulutsa ndalama, choncho imagwiritsidwa ntchito kwambiri m'mafoni am'manja, kuvala kwanzeru ndi zinthu zina zamagetsi.
Maselo a 5.Polymer: nthawi zambiri amatanthawuza zinthu za polima monga maziko opangira selo, kawirikawiri, amagwiritsidwa ntchito ngati mbali yamagetsi yamagetsi ya lithiamu-ion ndi zipangizo zogwirira ntchito, osati m'malo mogwiritsa ntchito magetsi. zida ndi zida zogwirira ntchito.
6.Polymer maselo: amatchedwanso electrode pepala luso zipangizo polima monga m'munsi zinthu kupanga, kawirikawiri akhoza kukonzekera ntchito zitsulo ayoni polima kapena sanali ionic polima mwa munthu.

Mafunso omwe amafunsidwa kawirikawiri okhudza kugwiritsa ntchito mabatire a polima pa kutentha kochepa

Mavuto omwe amapezeka kawirikawiri ndi awa:

a. Palibe mtengo: Batire ikatulutsidwa, mpweya wambiri umapangidwa, ena omwe amatuluka mu batri.

b. Palibe kutulutsa: Mphamvu yamagetsi mkati mwa batire ya polima pa kutentha kochepa imachepa.

c. Kuwola kwa batire: Pamene kutentha kumatsika, mphamvu ya magetsi mkati mwa batire ya polima imawola mofulumira, ndipo kuchuluka kwa kuwonongeka kumadalira momwe batire la polima limapangidwira. d. Dera lalifupi kapena utsi. Popeza batire la polima palokha silingathe kupirira kutentha kwambiri, kuzungulira kwafupi kwa batire ya polima pa kutentha kochepa kwambiri kumatha chifukwa cha kusintha kwa chemistry ya electrolyte ndipo chifukwa chake kungayambitse ngozi, yomwe imafuna njira zina zodzitetezera batire la polima ku kuwonongeka komwe kumachitika chifukwa cha kutentha kwambiri.
