Nā noi o ka PTFE High-Temperature Fabric ma ka Lithium Battery Industry

Ma ke ʻano he kumu hana o ka PTFE kiʻekiʻe-mehana lole, Hāʻawi ʻo Jiangsu Aokai New Materials iā ʻoe i kahi hoʻolauna ʻoihana. I ka hana ʻana o ka pākaukau lithium, hoʻohana nui ʻia ka lole wela kiʻekiʻe o ka PTFE no ka pale ʻana, ka hoʻokaʻawale ʻana a me ka lawe ʻana i nā kaʻina hana nui ma muli o kona kūpaʻa wela kiʻekiʻe, ka inertness kemika a me ka waiwai non-stick. ʻO kona kūpaʻa ʻana i ka corrosion electrolyte e pili ana i nā koi ʻoihana ʻoi aku ka paʻakikī ma mua o ke kūpaʻa corrosion maʻalahi.

Noi Pono 1: Electrode Production and Cell Assembly

I ka hana ʻana i nā electrodes pākaukau a me nā kaʻina hana hui pū, hoʻohana nui ʻia ka PTFE kiʻekiʻe-mehana lole no ka lawe ʻana, pale a me ka hoʻokaʻawale ʻana i ka wela.

Electrode Drying Conveyor Belt  He mea lawelawe ia ma ke kāʻei conveyor i ka wā maloʻo kiʻekiʻe o nā electrodes maikaʻi a maikaʻi ʻole ma 120 ℃ ~ 180 ℃. ʻO kona ikehu haʻahaʻa haʻahaʻa e pale i ka hoʻopili ʻana o nā mea ternary, graphite a me nā slurries ʻē aʻe, e pale aku i ka contamination a me ka hōʻino ʻana i nā coatings electrode.

Cell Hot Press Sealing  Me ka mānoanoa maʻamau o 0.18 mm, hana ʻo ia ma ke ʻano he kaʻawale a me ka pale pale ma waena o ke poʻo kaomi wela a me ka cell pouch i ka wā hoʻopaʻa wela. Kūleʻa i nā mahana ma luna o 240 ℃, e hōʻoia i ka hoʻololi ʻana o ka wela, pale i ka hoʻopili ʻana a hoʻomaikaʻi i ka hoʻoulu ʻana.

Tab Welding a me Hot Press Protection e like me ka pale a me ka mea hoʻokaʻawale i ka wā wili tab a me ke kaomi wela ma kahi o 200 ℃.  Hoʻohana ʻia ʻo Ke hōʻike nei i ka insulation kiʻekiʻe me ka dielectric mau ma lalo o 2.6, pale maikaʻi ia i nā pōkole pōkole, pale i ka mahu electrolyte, a pale i ka piʻi ʻana o ke kūpaʻa ma muli o ka corrosion a me ka oxidation o nā pā keleawe / alumini.

Noi Pono 2: Hui Pūʻali Puke Paʻa a me ka Palekana Pūnaewele

I ka hui pūʻulu pākaukau, e kālele ana i ka palekana uila a me ka hoʻokele wela.

ʻO ka hoʻokaʻawale ʻana ma waena o nā kelepona  i waiho ʻia ma waena o nā pūnaewele hoʻokahi, hāʻawi ia i ka insulation maikaʻi loa a hiki i ka UL94 V-0 grade , e pale ana i nā pōkole pōkole a me ka hoʻolaha ʻana o ka holo wela.

ʻO ka uwea kūloko a me ka pale ʻana  Hoʻopili ʻo ia i nā wili uila kiʻekiʻe a me nā mea hoʻohui e hāʻawi i ka insulation kiʻekiʻe-mehana a me ka sila ʻana, e pale aku i nā pōkole pōkole i hana ʻia e ka electrolyte corrosion.

ʻO ka ʻōnaehana hoʻokele wai wela  me kahi ākea ākea ākea o -196 ℃ ~ 300 ℃  a me ka conductivity thermal controllable, hoʻohana ʻia ia ma ke ʻano he kumu kumu no nā gaskets insulation wela a me nā pepa conductive thermal e kaulike i ka mahana o loko o nā pā pākaukau.

Hoʻopili ʻia i ka hoʻopaʻa ʻia ʻana o ka hale pākaukau holoʻokoʻa  , pale ʻo ia i ka hoʻokomo ʻana o ka wai o waho a me ka ʻino mai ka leaka electrolyte liʻiliʻi i loko.

Pono Kūikawā 1: Kūʻē maikaʻi loa i nā ʻāpana Electrolyte like ʻole

He mea ʻino loa ka lithium battery electrolyte, no laila, ʻo ke kūpaʻa kemika he hōʻailona koʻikoʻi o ka PTFE lole wela kiʻekiʻe:

Organic Solvents  ʻO nā mea electrolyte nui e like me Ethylene Carbonate (EC) a me Dimethyl Carbonate (DMC) he mau mea hoʻoheheʻe polar ikaika. E pehu a hoʻoheheʻe ʻia nā plastik maʻamau i ka wā e ʻike ʻia ai, ʻoiai ʻaʻole i hoʻopilikia ʻia ka PTFE.

ʻO Corrosive Electrolytes  Lithium Hexafluorophosphate (LiPF₆), ka paʻakai electrolyte koʻikoʻi, ua maʻalahi i ka makū a me ka wela a hiki ke hoʻoheheʻe ʻia e hana i ka Hydrofluoric Acid (HF). He ʻino loa ka HF a hiki ke hoʻopau i ke aniani a me ka hapa nui o nā metala. Hāʻawi ka PTFE kiʻekiʻe-mehana lole i ke kūʻē kūʻē i ka waika hydrofluoric a mālama i ka hana paʻa i loko o ia ʻano ʻino.

Electrochemical Stability  Ma lalo o nā kūlana hana uila kiʻekiʻe a me ka hoʻokuʻu ʻana i loko o nā pila, hōʻike ʻo PTFE i nā waiwai kemika paʻa, ʻaʻohe hopena ʻaoʻao me ka electrolyte a ʻaʻohe catalytic decomposition o ka electrolyte.

ʻO ka hoʻoheheʻe ʻia ʻana o ka paʻakai e hoʻoheheʻe ʻia  i ka paʻakai, ʻo ia ka PTFE kiʻekiʻe-mehana lole e hōʻike ana i ka hoʻomanawanui maikaʻi loa.

Koi Kūikawā 2: Hoʻokō i nā Kūlana Paʻa Paʻa

ʻO nā waiwai waiwai nui ke kumu; ʻO ke kūpaʻa lōʻihi i nā kaiapuni pākaukau maoli e pono e hele i nā hoʻokolohua hana koʻikoʻi:

Electrolyte Immersion Aging Test  ʻO kēia ke ʻano hōʻoia pololei a koʻikoʻi. Hoʻokomo ʻia nā laʻana i loko o ka electrolyte simulated a mālama ʻia no nā lā a i ʻole he pule ma ka lumi wela a i ʻole nā ​​​​mahana kiʻekiʻe e like me 60 ℃ a me 85 ℃. ʻAʻole hōʻike nā huahana kūpono i ka ʻeleʻele o ka ʻili, delamination a i ʻole ka hoʻoheheʻe ʻana me ka pohō haʻahaʻa haʻahaʻa.

I ka hōʻuluʻulu ʻana, hana ʻia ka lole wela kiʻekiʻe o ka PTFE ma ke ʻano he uhi pale, pale kaʻawale a me ka lawe ʻana i ke ala ma waena o ka hana ʻana i ka pā lithium. Ke hoʻomau nei i ka ʻino electrolyte koʻikoʻi i loko o nā cell a i ʻole ka hāʻawi ʻana i ka pale paʻa i nā kaʻina hana wela kiʻekiʻe e like me ke kaomi wela a me ka welding, pono kāna hana hilinaʻi e hōʻoiaʻiʻo i ka hopena o ka hana, ka palekana hana a me ke ola pōʻai lōʻihi o nā pā lithium.

Hāʻawi ʻia ka ʻike ma luna e Jiangsu Aokai New Materials Technology Co., Ltd.

Inā makemake ʻoe e aʻo i nā kikoʻī e pili ana i nā palena ʻenehana, nā hiʻohiʻona noiʻi a me nā hoʻonā i hoʻopili ʻia o kā mākou huahana piha, me ka PTFE kiʻekiʻe-mehana lole, PTFE kiʻekiʻe-mehana adhesive lipine, PTFE kiʻekiʻe wela mesh kāʻei, seamless fusing mīkini kāʻei, hoʻokahi ʻaoʻao PTFE uhi lole, kiʻekiʻe-kū pale conveyor kāʻei a me ke kiʻekiʻe e pili ana iā mākou.
