Likopo tsa Lesela la Mocheso o Phahameng oa PTFE ho Indasteri ea Battery ea Lithium

Joaloka moetsi oa mohloli oa lesela la mocheso o phahameng oa PTFE, Jiangsu Aokai New Materials e u fa kenyelletso ea setsebi. Ha ho etsoa betri ea lithium, lesela la mocheso o phahameng oa PTFE le sebelisoa haholo-holo bakeng sa tšireletso, ho itšehla thajana le ho fetisa lits'ebetsong tsa bohlokoa ka lebaka la ho hanyetsa mocheso o phahameng, ho se sebetse ha lik'hemik'hale le thepa e se nang thupa. Ho hanyetsa ha eona ho corrosion ea electrolyte ho kenyelletsa litlhoko tse matla tsa indasteri ho feta ho hanyetsa ha kutu.

Kopo ea Konokono 1: Tlhahiso ea Electrode le Kopano ea Lisele

Ha ho etsoa li-electrode tsa betri le mekhoa ea ho kopanya lisele, lesela la PTFE le nang le mocheso o phahameng le sebelisoa haholo bakeng sa ho tsamaisa, ho sireletsa le ho itšehla thajana ka mokhoa o chesang.

Electrode Drying Conveyor Belt  E sebetsa e le lebanta la conveyor nakong ea ho omisoa ha mocheso o phahameng oa li-electrode tse ntle le tse mpe ho 120 ℃ ~ 180 ℃. Matla a eona a tlaase a holim'a metsi a thibela ho khomarela lisebelisoa tsa ternary, graphite le li-slurries tse ling, ho qoba ho silafala le ho senya liphahlo tsa electrode.

E na le mocheso o phahameng o nang le dielectric kamehla ka tlase ho 2.6, ka katleho e qoba lipotoloho tse khutšoanyane, e hanyetsa mouoane oa electrolyte, 'me e thibela ho eketseha ha khanyetso e bakoang ke ho bola le oxidation ea li-tab tsa koporo / aluminium.

Kopo ea Core 2: Kopano ea Battery Pack le Tšireletso ea Tsamaiso

Kopanong ea pakete ea betri, e shebana le polokeho ea motlakase le taolo ea mocheso.

Insulation Isolation Pakeng tsa Lisele  E behiloe pakeng tsa lisele ka bomong, e fana ka tšireletso e babatsehang le ho fokotsa lelakabe ho fihlela ho UL94 V-0 grade , ho thibela lipotoloho tse khutšoanyane le ho ata ha ho baleha ha mocheso.

Ka hare ho Wiring le Tšireletso ea Karolo  E phuthela lithapo tse phahameng tsa motlakase le li-connectors ho fana ka mocheso o phahameng oa mocheso le ho tiisa, ho qoba lipotoloho tse khutšoanyane tse bakoang ke ho bola ha electrolyte.

Thermal Management System Auxiliary Material  E na le mefuta e mengata ea ho hanyetsa mocheso ea -196 ℃ ~ 300 ℃  le conductivity ea mocheso e laolehang, e sebelisoa e le lisebelisoa tsa motheo bakeng sa li-gaskets tsa mocheso oa mocheso le lishiti tse tsamaisang mocheso ho leka-lekanya mocheso o ka hare oa lipakete tsa betri.

Ho Tiisa Kakaretso ea Battery Pack  E sebelisoa ho tiisoa ha matlo a pakete ea betri, e hanela ho kenella ha mongobo ka ntle le ho bola ho tsoa ho lutla ho honyane ha electrolyte ka hare.

Tlhokahalo e Khethehileng ea 1: Khanyetso e Ntle ho Likarolo tse fapaneng tsa Electrolyte

Lithium battery electrolyte e senya haholo, kahoo khanyetso ea lik'hemik'hale ke pontšo ea bohlokoa ea ts'ebetso ea PTFE lesela la mocheso o phahameng oa mocheso:

Organic Solvents  Likarolo tse ka sehloohong tsa electrolyte tse kang Ethylene Carbonate (EC) le Dimethyl Carbonate (DMC) ke lihlaseli tse matla tsa polar. Li-plastiki tse tloaelehileng li tla ruruha kapa esita le ho qhibiliha ha li pepesitsoe, ha PTFE e ntse e sa amehe ka ho feletseng.

Corrosive Electrolytes  Lithium Hexafluorophosphate (LiPF₆), letsoai la mantlha la electrolyte, e na le kutloelo-bohloko ho mongobo le mocheso 'me e bola habonolo ho hlahisa Hydrofluoric Acid (HF). HF e senya haholo 'me e ka senya likhalase le litšepe tse ngata. Lesela la mocheso o phahameng oa PTFE le fana ka khanyetso e ikhethang ho hydrofluoric acid mme le boloka ts'ebetso e tsitsitseng libakeng tse thata joalo.

Electrochemical Stability  Tlas'a maemo a ts'ebetso a matla a phahameng le a ho ntša tefiso ka har'a libeteri, PTFE e na le lisebelisoa tse tsitsitseng tsa lik'hemik'hale, ha e hlahise maikutlo a lehlakoreng le electrolyte ebile ha e na ho bola ha motlakase oa electrolyte.

Salt Spray Corrosion Resistance  Electrolyte leakage leakage e etsa setlolo sa letsoai se senyang haholo, moo lesela la PTFE la mocheso o phahameng le bonts'ang mamello e ntle haholo.

Tlhokahalo e Khethehileng ea 2: Ho Kopana le Maemo a Tletseng a Ts'ebetso ea Betri

Lintho tse phahameng tsa thepa ke tsa motheo; botsitso ba nako e telele tikolohong ea 'nete ea betri e tlameha ho feta liteko tse matla tsa ts'ebetso:
