Kunyatsoongorora kwe lithium ion bhatiri kuputika

Awdur: Iflowpower - Leverantör av bärbar kraftverk

Iyo lithium ion bhatiri musimboti Iyo lithium ion bhatiri inoumbwa neiyo yakanaka electrode, anode, diaphragm, uye electrolyte. Iyo yakanaka uye isina kunaka electrode layer yakanyatso kukungurutswa pamwe chete, uye iyo layer uye layer inoparadzaniswa kubva kune insulator, uye yakanaka uye yakaipa inonyudzwa mu electrolyte. Mabhatiri eCylindrical uye mabhatiri emakona akashandiswa se lithium ion bhatiri chimiro bhatiri inoumbwa maviri akasiyana e lithium-insertic makomisheni, zvichiteerana.

Iyo yakanaka electrode zvinhu ndeye yakasimba shanduko yesimbi oxide, simbi oxide, simbi sulfide, nezvimwe zvakadaro. kushambadzira Iyo yakanaka electrode zvinhu zvinowanzoshandiswa mu lithiamu-ion mabhatiri ndiyo inonyanya kushandiswa anode zvinhu zvekuchinja simbi oxides. Iyo anode zvinhu yakasimba inorganic isiri-simbi zvinhu, simbi-isina-metallic macomposites, simbi oxides, nezvimwe zvakadaro.

lithium iron phosphate positive uye negative material Iyo electrode electrode material inoumbwa pane conductive material inosarudza voltage uye simba electrolyte yebhatiri sechikamu chakasimba che lithium ion bhatiri, uye inotamba chishuwo chekufambisa ikozvino panguva yekuchaja bhatiri uye kubuda. Kuti udzivise zvinhu zvakanaka uye zvakashata zve electrode zvakanyudzwa mu electrolyte mumushonga we electrolytic, chinhu chakanaka uye chisina kunaka che electrode chinoparadzaniswa kubva kune chakanaka uye chisina kunaka che electrode chinonyudzwa mu electrolyte. Iyo LI inotorwa kubva kune yakanaka electrode, uye iyo yakaipa electrode yakaiswa mukati meiyo yakaipa electrode, iyo yakanaka electrode iri mune lithiamu state, muripo wekubhadhara ma electrons unopiwa nekunze redunhu kuti ive nechokwadi chechiyero chechaji.

Kubuda kwacho kunoenderana nekubuda, uye Li inobviswa kubva kune yakaipa electrode uye inoiswa mukati meiyo cathode zvinhu ne electrolyte. Pasi pemamiriro akajairwa ekuchaja uye ekuburitsa, lithium ion inodzikwa uye inobviswa pakati peyakaiswa kabhoni zvinhu uye akaturikidzana zvimiro, izvo zvinongokonzera shanduko mukuparadzana kwechinyorwa pasina kukuvadza chimiro chavo chekristaro. Munguva yekuchaja uye yekuburitsa maitiro, chimiro chemakemikari cheiyo negative electrode zvinhu haina kuchinjika.

Iyo ion reaction equation iri kuramba isingagoneki kuwedzera matanho ekuchengetedza mukati mebhatiri, sezvo iri kutsvaga huwandu hwepamusoro kuwedzera hupenyu hwebhatiri. Kubva muna 1991 Lithium-ion bhatiri kushambadzira kusvika kune yakachata, simba rekuti lithium-ion mabhatiri akawedzera maitiro mana kana kashanu kuputika kwebhatiri lithium-ion. Saka tinonzwisisa kuti inoshanda sei, saka tinogona kunzwisisa kuti chepakutanga chakakonzera Lithium ion bhatiri kuputika.

Kuchaja uye kuburitswa kwe lithium bazi crystal kukura bhatiri ndiko kudzoka kutamiswa kwe lithium ions. Panguva yekuchaja, lithium ions inoderedzwa kuita simbi lithium yakaiswa mune iyo yakaipa electrode. Kazhinji, lithium inogona kuiswa mukati me interlayer structure, iyo inogona kukura pamusoro pe electrode nekuda kwekusava nechokwadi kwekukura, uye kukura kwekukura kune imwechete yakabaiwa chimiro sebazi, iyo inogona kukuvadza diaphragm yebhatiri, zvichiita kuti ipfupi pfupi mukati mebhatiri.

Uye kuputika kwebhatiri. Kana bhatiri risina kukwana, zvimedu zvesimbi zvinobatanidza iyo yakanaka yakaipa electrode kuburikidza nebhatiri insulating layer, shandura nzira yezvino, zvichiita kuti zvinhu zvemukati zvidzike, kuitira kuti kemikari iite inorasikirwa nekutonga, kusunungura kupisa kwakawanda, kupisa bhatiri yepakiti bhatiri Kuchaja bhatiri redu razvino rine system yekudzivirira, mhinduro yebhatiri voltage, ine yambiro pamusoro pechaji, izvo zvinogona kukonzera kuwandisa, bhatiri chengetedzo kana bhatiri inokuvadza kana bhatiri rinokanganisa. cathode zvinhu Kuenderera mberi kubviswa uye kuiswa mune negative electrode zvinhu. Kana iyo yakanyanya lithium yakamisikidzwa mucarbon negative electrode ikasvikwa, iyo yakawandisa lithium ichaisa pane negative electrode zvinhu muchimiro chelithium metal, zvakaderedza zvakanyanya kugadzikana kwebhatiri.

Kunyangwe kuputika kwakabatana ne lithium-ion bhatiri, kwete chete iyo bhatiri huwandu huri kuvandudzwa, asi kuchengetedza kuita hakugone kuregererwa. Nhasi, vamwe vanogadzira mabhatiri vane chiyero chekuchengetedza chepamusoro, kunyangwe kuona mabhatiri. Isu tinonzwisisa kuti kana mbambo ichipinda mubhatiri, ichabatanidza zvakananga kune iyo yakanaka yakaipa, iyo ichaita kuti mukati mapfupi dunhu.

Iyo gel electrolyte uye polymer electrolyte zvakare iri mukuenderera mberi nekuongorora, kunyanya kugadzirwa kwepolymer electrolyte, hapana fluid organic electrolyte volatilization mubhatiri, iyo inovandudza zvakanyanya kuchengetedzwa kwebhatiri.
