Dzima rairo

Neraki, semugumisiro webasa rangu rekare, ndakabvisa mazana emabhatiri mumaoko angu, kusanganisira lithium-ion iron phosphate mabhatiri, terpolymer lithium mabhatiri, flexible pack mabhatiri uye cylindrical mabhatiri. Nhasi ndichaparadzana uye ndikuratidze mamiriro emukati webhatiri.

Sezvo lithium ions ichipinda, graphite anode zvishoma nezvishoma inoshanduka goridhe, asi zvakaoma kuona anode kuburikidza nekushanduka kwemavara. Isu tinowanzo tonga kuchaja uye kuburitsa mashandiro uye kunaka kwebhatiri nekubvisa bhatiri uye nekutarisa chimiro cheiyo negative electrode.

SOC = 7%, paiva nezvikamu pakati pe electrode, uye electrode haina kuchinja ruvara.

Apo SOC = 14%, zvimedu zviri pakati pe electrode zvinogona kuonekwa. Kuchinja kwemavara kudiki.

SOC iri 26% zvishoma bhuruu.

SOC = 53.9%, inoshanduka bhuruu, mabhuru anogona kuonekwa.

Charge status = 70.0%, kubva kune yakasviba yepepuru kusvika kune yakatsvuka, inooneka isina kuchaja nzvimbo dema. Hapana lithium ion precipitation yakawanikwa.

Kuchaja kwakazara =81.5%, kutendeukira kugoridhe, inooneka dema isina kubhadhariswa nzvimbo. Iwe unogona kuona kushanduka kwewhite lithium.

Sezvinogona kuonekwa kubva pamufananidzo uri pamusoro, apo nyika inopomerwa iri pasi pe50%, iyo electrode state haina kuchinja zvakanyanya. Kuchinja kwe electrode kunogona kuonekwa pamusoro pe50%. Sezvinoratidzwa mumufananidzo 4, nhamba huru yemabhubhu inogona kuwanikwa yakatenderedza 3.6V. Inogona kufungidzirwa kuti kune kuchinja kukuru pakati peMufananidzo 5 uye Mufananidzo 6. Nyika inopomerwa inoshanduka ne10% chete, asi electrode state yakasiyana zvachose.

Electrode state kana bhatiri SOC=100%. Chikamu chichena chinonzi lithium.

Mushure mokubvisa chikamu chichena, pamusoro pedanda rezasi harishanduki goridhe, zvichiratidza kuti lithium ions haina kuiswa mune yakanaka electrode zvinhu. Muchidimbu, iyo yakanaka zvinhu muchikamu ichi chemidziyo inodzivirira lithium ions kubva mukumisikidza, saka lithium ions inokwira kumusoro. Zvinofungidzirwa kuti mabinders (CMC neSBR) akagoverwa zvisina kuenzana pane electrode pamusoro uye akaputirwa nekabhoni mune anode zvinhu, zvichitungamira kune lithium ion implantation.

Kana iyo nyika yakachajwa iri 100%, mazhinji emavara matema inzvimbo dzisina kubhadhariswa. Kune akawanda mavara matema pabhatiri, icho chikonzero chakakosha chekuderera kwebhatiri. Izvo zvakakosha zvinokonzeresa mavara matema ndiko kufanana kweslurry, iyo density yekudzora kurongeka kweiyo coating surface, tension control yekumonereka uye kuumbwa kwegasi.
