Umkhuba wokuthuthukiswa kwe-copper foil yezinto zebhethri ye-lithium uchazwa ngokuningiliziwe

I-copper foil iyinto esemqoka ye-anode yamabhethri e-lithium-ion, enomthelela obalulekile kumandla webhethri nokunye ukusebenza, okulinganiselwa ku-5% -8% wezindleko zamabhethri e-lithium-ion. Kumongo wemboni yebhethri yamanje ukuthuthukisa ikhwalithi nokunciphisa izindleko, izacile kakhulu futhi ephezulu igama elingukhiye lokuthuthukiswa kwayo kobuchwepheshe kanye nesidingo semakethe.

Njengoba ukuminyana kwamandla kuqhubeka nokukhuphuka, abakhiqizi bamandla ebhethri ye-lithium-ion nabo babeka izimfuno eziphakeme kucwecwe lwethusi, nge-foil yethusi encane kakhulu, ucwecwe lwethusi oluqinile oluqinile, ucwecwe lwethusi olunezimbotshana, ucwecwe lwethusi oluboshwe, njll. eza emakethe. Ngokufanayo ne-aluminium foil enezimbotshana, nakuba ingakhuphula ukulayishwa kwezinto ezisebenzayo ezingezinhle futhi ivumele i-electrode engemihle ukuthi yakhe inethiwekhi ye-conductive enezinhlangothi ezintathu, kusengenakugwenywa ukubhekana nobunzima obukhulu bokuxazulula ekukhiqizeni ngobuningi, futhi kusekhona okuthile. ubunzima bezobuchwepheshe ekwakhiweni, ukufakwa kwe-laminating, ukugunda nokusonta.

Ngokufanayo ne-aluminium ehlanganisiwe, i-foil yethusi ene-coating inganciphisa kakhulu ukuxhumana kwangaphakathi ukumelana, ithuthukise ukubopha, isheshise ukumanzisa kwe-electrolyte, ithuthukise izinga lokushisa eliphansi ukusebenza, inciphise i-burr ohlelweni, ukuvikelwa komqoqi, njll. Nokho, kusukela manje, umdlalo nge-electrode engalungile impahla ayilungile kakhulu, ngakho-ke ayikasetshenziswa ngobuningi, futhi ucwaningo olwengeziwe nokwenza kahle kuyadingeka.

Ngemuva kwemboni entsha yezimoto zamandla isekelwa ngokuqinile yinqubomgomo kazwelonke, amandla amabhethri e-lithium-ion azoshayela imakethe ye-lithium yethusi ye-lithium ukuze kugcinwe ukuthambekela okuphezulu okukhuphukayo.

Ngokombono wezobuchwepheshe, i-lithium copper foil ezacile isho ukumelana okuncane, ngakho-ke ukusebenza kwamabhethri e-lithium-ion anjengokuminyana kwamandla nakho kuzothuthukiswa. Ngaphezu kwalokho, ukushuba okuncane kwe-lithium ye-copper foil, isisindo sebhethri ehambisanayo sizoba lula, esinganciphisa ngempumelelo izindleko zezinto zokusetshenziswa ze-foil yethusi. Ngakho-ke, umkhuba uwukusebenzisa ucwecwe lwethusi lwe-lithium-ion olulula futhi olulula ngokuzayo.

ibhethri yethoyizi likagesi, impahla ye-elekthronikhi, ibhethri yerutha engenantambo, usayizi webhethri ongu-18650, umthamo webhethri yesipika sebluetooth, ibhethri le-glawell cordless electric mop battery, 21700 ibhethri elingcono kakhulu, lithium nickel manganese cobalt oxide battery, bluetooth speaker battery 2000mah, lithium battery structure, victron battery monitor, cylindrical lithium ion ibhethri.
