Lithium mabhatiriimhando yebhatiri inoshandisa lithium simbi kana lithium alloy seyakaipa electrode zvinhu uye inoshandisa isiri-aqueous electrolyte mhinduro. Nekuda kwekushanda kwakanyanya kwemakemikari zvimiro zvelithium simbi, kugadzirisa, kuchengetedza, uye kushandiswa kwelithium simbi kune zvakanyanya kudiwa kwezvakatipoteredza. Tevere, ngatitarisei kune homogenization, kupfekedza, uye rolling maitiro mukugadzirira kwe lithium mabhatiri.
Positive uye yakaipa electrode homogenization
Iyo electrode ye lithium-ion bhatiri ndiyo inonyanya kukosha chikamu chebhatiri cell. Iyo yakanaka uye isina kunaka electrode homogenization inoreva nzira yekugadzirira ye slurry yakavharwa pane yakanaka uye yakaipa electrode mapepa e lithium ion. Kugadzirira kweslurry kunoda kusanganisa iyo yakanaka electrode zvinhu, iyo yakaipa electrode zvinhu, conductive agent uye binder. Iyo slurry yakagadzirwa inoda kuva yakafanana uye yakagadzikana.
Vagadziri velithium bhatiri vakasiyana vane yavo homogenization maitiro mafomula. Kurongeka kwekuwedzera zvinhu, chiyero chekuwedzera zvinhu uye iyo inosimudzira maitiro muhomogenization process ine simba guru pakuita homogenization. Mushure meiyo homogenization, iyo slurry inoda kuongororwa kune yakasimba yemukati, viscosity, fineness, nezvimwe kuti ive nechokwadi chekuti slurry performance inosangana nezvinodiwa.
Coating
Iyo yekupfekedza maitiro inzira yakavakirwa pakudzidza kwezvimiro zvemvura, umo imwe kana akawanda akaturikidzana emvura akaputirwa pane substrate. Iyo substrate inowanzo chinjika firimu kana kutsigira bepa, uye ipapo yakavharwa yemvura yekuputira inoomeswa muchoto kana kupora kuti iite firimu layer ine akakosha mabasa.
Coating inzira yakakosha mukugadzirira kwemasero ebhatiri. Unhu hwekuputira hunoenderana zvakananga nehutano hwebhatiri. Panguva imwecheteyo, mabhatiri e-lithium-ion anonyanya kunetseka kune unyoro nekuda kwemaitiro ehurongwa. Huwandu hwekunyorova hunogona kukanganisa zvakanyanya kushanda kwemagetsi ebhatiri; chiyero chekushanda kwekuputira chakanangana nezviratidzo zvinoshanda senge mutengo uye chiyero chakakodzera.
Coating kugadzira nzira
Iyo yakavharidzirwa substrate inosunungurwa kubva kune inosunungura mudziyo uye inodyiswa mumushini wekuputira. Mushure mokunge musoro nemuswe we substrate zvabatanidzwa kuti zvigadzire bhanhire rinoramba riri patafura yekubatanidza, ivo vanodyiswa mumudziyo wekugadzirisa tension uye otomatiki kutsauka kururamisa mudziyo nedhishi rekudhonza, uye pinda mudziyo wekupfekedza mushure mekugadzirisa shizha nzira kushushikana uye shizha nzira chinzvimbo. Iyo pole piece slurry yakaputirwa muzvikamu mumudziyo wekuputira zvinoenderana neyakafanotemerwa yekuvhara huwandu uye hurefu husina chinhu.
Kana yakapetwa kaviri-yakapetwa, iyo yekumberi yekupfekedza uye isina blank kureba inozorongerwa otomatiki kuti ipfeke. Iyo electrode yakanyorova mushure mekuputira inotumirwa kune yekuomesa chiteshi kuti iome. Iyo tembiricha yekuomesa inoiswa zvinoenderana nekumhanya kwekuputira uye ukobvu hwekuputira. Iyo yakaomeswa electrode inopetwa mushure mekugadzirisa tension uye otomatiki kutsauka kururamisa kune inotevera nhanho yekugadzirisa.
Rolling
Iyo yekutenderedza maitiro e lithium bhatiri pole zvimedu inzira yekugadzira iyo yakafanana inotsikirira mbishi zvinhu senge zvinhu zvinoshanda, conductive agents uye mabhinda pasimbi foil. Kuburikidza neiyo rolling process, iyo pole chidimbu inogona kuve nepamusoro electrochemical inoshanda nzvimbo, nekudaro ichivandudza simba remagetsi uye kuchaja uye kuburitsa kuita kwebhatiri. Panguva imwecheteyo, maitiro ekukungurutsa anogonawo kuita kuti chidimbu chedanda ive nepamusoro pesimba rechimiro uye kuenderana kwakanaka, izvo zvinobatsira kuvandudza kutenderera hupenyu uye kuchengetedzeka kwebhatiri.
Rolling yekugadzira maitiro
Maitiro ekutenderedza maitiro e lithium bhatiri pole zvidimbu zvinonyanya zvinosanganisira kugadzirwa kwezvinhu, kusanganisa, compaction, kuumbwa uye zvimwe zvinongedzo.
Kugadzirira kwezvinhu zvakasvibirira kusanganisa zvinhu zvakasiyana-siyana zvakaenzana uye kuwedzera huwandu hwakakodzera hwekunyungudutsa kuti uwane slurry yakagadzikana.
Iyo yekusanganisa link ndeyekusanganisa akasiyana mbizha zvinhu zvakaenzana kune inotevera compaction uye kuumbwa.
The compaction link ndeyekudzvanya slurry kuburikidza ne roller press kuitira kuti zvinhu zvinoshanda zvimedu zvinyatsorongedzwa kuti zvigadzire danda rine rimwe simba rekugadzirisa. Iyo yekuumba chinongedzo ndeyekubata danda netembiricha yakakwira uye kudzvanywa kwepamusoro kuburikidza nemidziyo yakadai sedhindi rinopisa kugadzirisa chimiro uye saizi yedanda chidimbu.
Mhedziso
Iyo nzira yekugadzirira ye lithium mabhatiri yakaoma kwazvo, uye nhanho imwe neimwe yakakosha. Ramba wakatarira Heltec's blog uye isu ticharamba tichikuvandudza iwe neruzivo rwakakodzera nezve lithium mabhatiri.
Heltec Energy ishamwari yako yaunovimba nayo mukugadzira bhatiri pack. Nekutarisa kwedu kusingagumi pakutsvaga nekusimudzira, pamwe nehupamhi hwemabhatiri ezvishandiso zvedu, tinopa mhinduro imwe chete yekusangana nezvinodiwa neindasitiri. Kuzvipira kwedu kune kugona, mhinduro dzakagadzirirwa, uye kudyidzana kwakasimba kwevatengi kunotiita isu kuenda-kune sarudzo yevagadziri vebhatiri pack uye vatengesi pasi rese.
Kana uine chero mibvunzo kana uchida kudzidza zvakawanda, ndapota usazezasvika kwatiri.
