Iyo lithium ion bhatiri musimboti Iyo lithium ion bhatiri yakakosha kubva kune yakanaka electrode, iyo yakaipa electrode, diaphragm, uye electrolyte. Iyo yakanaka uye isina kunaka electrode layer yakanyatso kukungurutswa pamwe chete, uye iyo layer inopatsanurwa kubva kune iyo, uye yakanaka uye yakaipa inonyudzwa mu electrolyte . Mabhatiri eCylindrical uye mabhatiri akaenzana akashandiswa se lithium ion bhatiri chimiro bhatiri, iyo inoumbwa nemhando mbiri dzakasiyana-siyana lithium-insert compounds, yakanaka uye yakaipa.

Iyo node zvinhu zvakakosha kune shanduko yesimbi okisidi, simbi okisijeni, simbi sulfides, nezvimwe zvakadaro. Commercial Positive electrode zvinhu zvinowanzoshandiswa mumabhatiri e-lithium-ion ndiyo inonyanya kushandiswa anode zvinhu zvekushandura simbi okisidi yakakosha inorganic isiri-metallic materials, metal-non-metallic composites, metal oxides, nezvimwe zvakadaro. Lithium iron phosphate yakavharwa Iyo electrode electrode material inoumbwa pane conductive material inosarudza voltage uye simba electrolyte yebhatiri sechikamu chakakosha che lithium ion bhatiri, uye inotamba kushandiswa kwakakosha kwekufambisa ikozvino panguva yekuchaja bhatiri uye kubuda.

Kuti udzivise zvinhu zvakanaka uye zvisina kunaka zve electrode zvakanyudzwa mu electrolyte nekuda kweumwe neumwe, iyo yakanaka uye yakaipa electrolytic diaphragm inoparadzaniswa. Iyo lithium ion yechipiri bhatiri ichokwadi bhatiri iro rakashata mu lithium ion concentration. kuchaja I LI inotorwa kubva kune yakanaka electrode, uye iyo yakaipa electrode yakaiswa mukati meiyo yakaipa electrode, iyo yakanaka electrode iri mu lithium 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 yave kutsvaga huwandu hwepamusoro kuwedzera hupenyu hwebhatiri. Kubva 1991, iyo lithium-ion bhatiri inotengeswa kusvika ikozvino, simba rekuti lithium-ion mabhatiri akawedzera kana kana kashanu lithium-ion bhatiri kuputika meshini. Saka tinonzwisisa kuti inoshanda sei, saka tinogona kunzwisisa kuti chii chinokonzerwa ne lithium ions.

Kuputika kwebhatiri . 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 pane chakakanganisika mubhatiri, zvimedu zvesimbi zvinobatanidza iyo yakanaka yakaipa electrode kuburikidza neyakavharira bhatiri dhizaini, shandura nzira yeyazvino, zvichiita kuti zvinhu zvemukati zvidzikisire, zvichiita kuti kemikari iite, kuburitsa kupisa kwakawanda, kupisa bhatiri bhatiri bhatiri Kuchaja bhatiri redu razvino rine system yekudzivirira iyo inodzosera kumashure bhatiri voltage kudzivirira kuwandisa, izvo zvinogona kukonzera kuwandisa, bhatiri kuchengetedzwa kwechaji kana bhatiri inoshaja. Ramba uchibviswa uye kuiswa mukati meiyo negative electrode material.

Kana iyo yakanyanya lithium yakamisikidzwa mucarbon negative electrode, yakawandisa lithium inoisa pane negative electrode zvinhu muchimiro chelithium simbi, zvakaderedza zvakanyanya kugadzikana kwebhatiri. Kunyangwe kuputika kwakabatana ne lithium-ion bhatiri, kwete chete iyo bhatiri huwandu huri kuvandudzwa, asi kuchengetedza kuita hakugone kuregererwa. Iye zvino vamwe vanogadzira mabhatiri vane chiyero chekuchengetedza chepamusoro, kunyangwe kuona mabhatiri.

Isu tinonzwisisa kuti kana mbambo ichipinda mubhatiri, ichabatana zvakananga kune iyo yakanaka yakaipa, izvo zvinokonzeresa mukati mapfupi maseketi. 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.
