Zvishandiso zvePTFE Yepamusoro-Tembiricha Fabric muLithium Battery Indasitiri

Semugadziri wekugadzira PTFE yakakwirira-tembiricha machira, Jiangsu Aokai Zvitsva Zvishandiso inokupa iwe sumo yehunyanzvi. Mukugadzira lithium bhatiri, PTFE high-temperature jira rinonyanya kushandiswa kudzivirira, kuparadzaniswa uye kuendesa mumiitiro yakakosha kuburikidza nekukwirira kwayo kwekushisa kwepamusoro, kusagadzikana kwemakemikari uye kwete-stick pfuma. Kupokana kwayo neelectrolyte corrosion kunosanganisira zvakanyanya kuomarara zvinodiwa mumaindasitiri pane zviri nyore kurwisa corrosion.

Core Application 1: Electrode Production uye Cell Assembly

Mukugadzira maelectrodhi ebhatiri uye maitiro ekubatanidza sero, PTFE jira rekushisa rinoshandiswa zvakanyanya kuburitsa, kudzivirira uye kupisa kudzvanya kuparadzaniswa.

Electrode Drying Conveyor Belt  Inoshanda sebhandi rekutakura panguva yekupisa kwepamusoro-tembiricha yemagetsi akanaka uye asina kunaka pa120 ℃ ~ 180 ℃. Simba rayo rakaderera pasi rinodzivirira kunamatira kwezvinhu zve ternary, graphite uye mamwe slurries, kudzivirira kusvibiswa uye kukanganisa kwe electrode coatings.

Cell Hot Press Chisimbiso  Neyakajairwa gobvu ye 0.18 mm, inoita seyakasarudzika uye yekudzivirira layer pakati peinopisa yekudzvanya musoro uye pouch cell panguva yekuvharwa kwekupisa. Inodzivirira kune tembiricha pamusoro pe240 ℃, inova nechokwadi chekuchinjisa kupisa kwakafanana, inodzivirira kunamatira uye inovandudza kurongedza goho.

Tab Welding uye Hot Press Dziviriro  Inoshandiswa sekudzivirira uye yekuzviparadzanisa zvinhu panguva yekubatira tebhu uye kupisa kudzvanya kutenderedza 200 ℃. Inobatanidza nepamusoro-soro yekudzivirira ne dielectric constant pazasi 2.6, inonyatso dzivirira mapfupi maseketi, inodzivirira electrolyte vapor, uye inodzivirira kuwedzera kwekudzivirira kunokonzerwa nekuora uye oxidation yemhangura / aluminium tabs.

Core Kushandisa 2: Bhatiri Pack Assembly uye System Dziviriro

Mukubatanidza bhatiri pack, inotarisa pakuchengetedza magetsi uye kutonga kwekupisa.

Insulation Isolation pakati peMasero  Akaiswa pakati pemasero ega ega, inopa yakanakisa kuvharidzira uye murazvo retardancy kusvika UL94 V-0 giredhi , kudzivirira mapfupi maseketi uye kupararira kwekupisa kwekupisa.

Internal Wiring uye Component Protection  Inoputira high-voltage wiring uye zvibatanidza kuti zvipe kupisa kwepamusoro-kupisa uye kuvhara, kudzivisa mafupi mafupi anokonzerwa ne electrolyte corrosion.

Thermal Management System Auxiliary Material  Iine yakafara tembiricha yekudzivirira ye -196 ℃ ~ 300 ℃  uye inodzoreka yekupisa conductivity, inoshandiswa seyakadzika zvinhu zvekupisa kupisa gaskets uye thermal conductive sheets kudzikamisa tembiricha yemukati yemabhatiri mapaketi.

Yakazara Battery Pack Chisimbiso  Inoshandiswa kune bhatiri pack chisimbiso chedzimba, inopikisa kunze kwemvura ingress uye ngura kubva kudiki kwemukati electrolyte kuvuza.

Chinodiwa Chinokosha 1: Yakanakisa Kupokana kune Yakasiyana Electrolyte Zvikamu

Lithium bhatiri electrolyte inoparadza zvakanyanya, saka makemikari kuramba chiratidzo chakakosha chekuita kwePTFE jira rekushisa-pamusoro:

Organic Solvents  Mishonga mikuru ye electrolyte yakadai seEthylene Carbonate (EC) uye Dimethyl Carbonate (DMC) zvinyungurutsi zvepolar zvakasimba. Mapurasitiki akajairwa achazvimba kana kunyungudika kana afumurwa, nepo PTFE inoramba isina kubatwa zvachose.

Corrosive Electrolytes  Lithium Hexafluorophosphate (LiPF₆), iyo yakakosha electrolyte munyu, inonzwira hunyoro uye kupisa uye inoora nyore kuburitsa Hydrofluoric Acid (HF). HF inoparadza zvakanyanya uye inogona kukanganisa girazi nesimbi zhinji. PTFE high-temperature jira rinopa kupikisa kwakanyanya kune hydrofluoric acid uye rinochengetedza kushanda kwakadzikama munzvimbo dzakaoma kudaro.

Electrochemical Stability  Under high voltage and charge-discharge operating conditions mukati memabhatiri, PTFE inogadzirisa zvinhu zvemakemikari yakagadzikana, haibudisi maitiro emagetsi ne electrolyte uye hapana catalytic decomposition ye electrolyte.

Salt Spray Corrosion Resistance  Electrolyte leakage inoumba yakanyanya kuora munyu pfapfaidzo, iyo iyo PTFE yepamusoro-tembiricha jira inoratidza kushivirira kwakanyanya.

Chinodiwa Chinokosha 2: Kusangana Nezvakaomesesa Mashandiro eBattery

Superior zvinhu zvinhu zvinokosha; kugadzikana kwenguva refu munzvimbo chaidzo dzebhatiri kunofanirwa kupfuudza bvunzo dzekuita:

Electrolyte Kunyudzwa Kuchembera Muedzo  Iyi ndiyo yakanyatsonanga uye yakakosha nzira yekusimbisa. Samples anonyudzwa muyedzero electrolyte uye anochengetwa kwemazuva kana mavhiki pakamuri tembiricha kana tembiricha yakakwira se60 ℃ uye 85 ℃. Zvigadzirwa zvinokwanisa kuratidza hapana kuputika kwepasi, delamination kana kunyungudika nekudzikira uremu zvakanyanya.

Muchidimbu, PTFE yakakwirira-tembiricha jira rinoita sechivharo chekudzivirira, chekuzviparadzanisa nevamwe uye kuendesa svikiro mukati mese lithium bhatiri kugadzira. Kunyangwe kutsungirira kwakakomba kweelectrolyte corrosion mukati memasero kana kupa dziviriro yakatsiga mumatanho ekupisa kwepamusoro senge kupisa kudzvanya uye welding, kuita kwayo kwakavimbika kwakakosha kuvimbisa goho rekugadzira, kuchengetedzwa kwekushanda uye hupenyu hurefu hwekutenderera kwemabhatiri e lithium.

Mashoko ari pamusoro apa anopiwa ne Jiangsu Aokai New Materials Technology Co., Ltd.

Kana iwe uchida kudzidza zvakadzama nezve tekinoroji parameters, mamiriro ekushandisa uye yakagadziridzwa mhinduro dzechigadzirwa chedu chakazara, kusanganisira PTFE yakakwirira-tembiricha jira, PTFE yakakwirira-temperature adhesive tepi, PTFE yakakwirira-temperature mesh bhandi, seamless fusing muchina bhandi, single-sided PTFE yakavharidzirwa jira, high-temperature temperature, please-high-temperature; taura nesu kuburikidza ne:
