Munyika yemabhatiri e lithium asingaonekwe zvakanaka, kune "muchengeti asingaonekwe" akakosha - muparidzi, anozivikanwawo se membrane yebhatiri. Inoshanda sechikamu chikuru chemabhatiri e lithium nezvimwe zvishandiso zve electrochemical. Yakagadzirwa zvakanyanya ne polyolefin (polyethylene PE, polypropylene PP), mamwe maparator emhando yepamusoro anoshandisawo ceramic coatings (semuenzaniso, alumina) kana zvinhu zvakasanganiswa kuti awedzere kudzivirira kupisa, zvichiita kuti ave zvigadzirwa zvemafirimu ane maburi. Kuvapo kwayo kunoshanda se "firewall" yakasimba, ichiparadzanisa ma electrodes akanaka neasina kunaka ebhatiri re lithium kudzivirira ma short circuits, uku ichishanda se "ion highway" yakapfava, ichibvumira ma ions kufamba zvakasununguka uye ichivimbisa kushanda kwebhatiri kwakajairika.
Kukura kwegiramu neukobvu hwemuchina wekuparadzanisa, zvinoita sezviri nyore, zvinovanza "zvakavanzika" zvakadzama. Kukura kwegiramu (kurema kweareal) kwezvinhu zve lithium battery separator hakungoratidzi chete kusarongeka kwema membrane ane ukobvu hwakafanana uye zvirevo zvezvinhu zvisina kugadzirwa asiwo zvine hukama hwakanyanya nehuremu hwezvinhu zvisina kugadzirwa zvemuchina wekuparadzanisa uye zvirevo zveukobvu hwayo. Kukura kwegiramu kunokanganisa zvakananga resistance yemukati, kugona kwerate, mashandiro e cycle, uye kuchengetedzeka kwemabhatiri e lithium.
Ukobvu hweseparator hwakakosha zvikuru pakushanda kwebhatiri uye kuchengetedzeka kwaro. Kufanana kweukobvu inzira yakasimba yekudzora hunhu panguva yekugadzira, ine kutsauka kunodiwa kuti igare mukati memazinga eindasitiri uye kushivirira kwekubatanidza bhatiri. Separator yakatetepa inoderedza kuramba kwemaion e lithium akagadziriswa panguva yekufambisa, zvichivandudza conductivity ye ionic uye kudzikisa impedance. Zvisinei, kutetepa kwakanyanya kunoderedza kuchengetedza kwemvura uye kuputira kwemagetsi, zvichikanganisa mashandiro ebhatiri.
Nekuda kwezvikonzero izvi, kuyedzwa kwekukora uye kusimba kwenzvimbo yemuchina wekubvisa mabara kwave matanho akakosha ekudzora hunhu mukugadzirwa kwebhatiri re lithium, zvichiratidza zvakananga mashandiro ebhatiri, kuchengetedzeka, uye kugara kwenguva refu. Kusimba kwakanyanya kwenzvimbo yemuchina kunokanganisa kutakurwa kwe lithium-ion, zvichideredza kugona kwemuchina; kusimba kwakanyanya kwenzvimbo yemuchina kunokanganisa simba remuchina, zvichikonzera njodzi yekuputika uye kuchengetedzeka. Maparavara akatetepa zvakanyanya anogona kukanganisa kupinda kwe electrode, zvichikonzera mapfupi emukati; maparavara akakora zvakanyanya anowedzera kusimba kwemukati, kuderedza kusimba kwesimba uye kushanda zvakanaka kwe charge-discharge.
Kuti vagadzirise matambudziko aya, Dacheng Precision inoburitsa nzira yayo yekuyera ganda neX-ray!
#X-ray areal density (ukobvu) chiyero chekuyera
Mudziyo uyu wakakodzera kuyedza zvinhu zvakasiyana-siyana, kusanganisira ceramics nePVDF, ine kurongeka kwekuyera kwechokwadi × 0.1% kana ±0.1g/m², uye yakawana chitupa chekusunungurwa pamwaranzi kuti ishande zvakachengeteka. Software yayo ine ma "heatmaps" enguva chaiyo, ma "otomatiki calibration calculation", mishumo yemhando yepamusoro, one-click MSA (Measurement System Analysis), uye mamwe mabasa akakosha, zvichigonesa rutsigiro rwakakwana rwekuyera kwechokwadi.

Tichitarisa mberi, Dacheng Precision ichazvisimbisa muR&D, ichienderera mberi kusvika padanho repamusoro retekinoroji uye ichibatanidza hunyanzvi mune zvese zvigadzirwa nebasa. Tichishandisa tekinoroji yemazuva ano, tichatsvaga mhinduro dzakangwara uye dzakarurama dzekuyera, tichivaka masisitimu ebasa retekinoroji anoshanda uye akavimbika kune vatengi vedu. Nehunyanzvi hwekugadzira zvigadzirwa zvepamusoro uye simba rekutungamira hunyanzvi, takazvipira kufambisa indasitiri yebhatiri re lithium kuenda kunguva itsva yekuvandudzwa kwemhando yepamusoro!
