1. Ngozi ye lithium ion bhatiri
Lithium ion bhatiri inogona kuve nengozi kemikari simba sosi nekuda kwechimiro chayo chemakemikari uye kuumbwa kwehurongwa.
(1) High chemical chiitiko
Lithium ndiro boka guru I chinhu muchikamu chechipiri chetafura yeperiodic, ine makemikari anoshanda zvakanyanya.
(2) High simba density
Mabhatiri eLithium ion ane simba rakanyanya repamusoro (≥ 140 Wh/kg), iro rakapetwa kanoverengeka iro renickel cadmium, nickel hydrogen nemamwe mabhatiri echipiri.Kana thermal runaway reaction ikaitika, kupisa kwakanyanya kunoburitswa, izvo zvinozotungamira kune zvisina kuchengetedzeka maitiro.
(3) Tora organic electrolyte system
Iyo organic solvent ye organic electrolyte system ndeye hydrocarbon, ine yakaderera decomposition voltage, nyore oxidation uye inopisa inopisa;Kana yadonha, bhatiri rinobata moto, kunyange kupisa uye kuputika.
(4) Mukana wepamusoro wemhedzisiro
Mune yakajairwa kushandiswa kwe lithium ion bhatiri, iyo kemikari yakanaka yekuita yekuchinjana pakati pesimba remagetsi uye kemikari simba inoitika mukati mayo.Zvisinei, pasi pemamwe mamiriro ezvinhu, akadai sekuwandisa, kuburitsa kana pamusoro pekushanda ikozvino, zviri nyore kukonzera kemikari yemativi maitiro mukati mebhatiri;Kana maitiro epadivi akawedzera, zvinokanganisa zvakanyanya kushanda uye hupenyu hwesevhisi yebhatiri, uye inogona kuburitsa huwandu hukuru hwegasi, izvo zvinokonzeresa kuputika nemoto mushure mekumanikidza mukati mebhatiri nekukurumidza, zvichitungamira kumatambudziko ekuchengetedza.
(5) Chimiro che electrode zvinhu hazvina kugadzikana
Kuwedzera kwekuita kwe lithium ion bhatiri kuchashandura chimiro che cathode zvinhu uye kuita kuti zvinhu zvive nesimba rakasimba re oxidation, kuitira kuti iyo inonyungudutsa mu electrolyte ichava neoxidation yakasimba;Uye mhedzisiro iyi haidzoreki.Kana kupisa kunokonzerwa nekuita kunounganidza, pachava nengozi yekukonzera kupisa kwemhepo.
2. Kuongororwa kwematambudziko ekuchengetedza kwe lithium ion battery products
Mushure memakore makumi matatu ekuvandudzwa kwemaindasitiri, zvigadzirwa zvemabhatiri e-lithium-ion zvakafambira mberi zvakanyanya mukuchengetedza tekinoroji, zvakanyatso kudzora kuitika kwemaitiro eparutivi mubhatiri, uye nekuona kuchengetedzwa kwebhatiri.Zvisinei, semabhatiri e-lithium ion anoshandiswa zvakanyanya uye zvakanyanya uye simba ravo resimba rakakwirira uye rakakwirira, kuchine zviitiko zvakawanda zvakadai sekukuvara kwekuputika kana kuyeuka kwechigadzirwa nekuda kwekugona kuchengetedza njodzi mumakore achangopfuura.Isu tinogumisa kuti zvikonzero zvikuru zvezvinetso zvekuchengetedza zve lithium-ion bhatiri zvigadzirwa ndezvizvi:
(1) Dambudziko rezvinhu
Zvinhu zvinoshandiswa pamagetsi emagetsi zvinosanganisira zvinhu zvakanaka zvinoshanda, zvinhu zvisina kunaka zvinoshanda, diaphragms, electrolytes uye mabhomba, nezvimwewo. Kusarudzwa kwezvinhu uye kuenzaniswa kwemaitiro ekugadzirisa zvinogadzirisa kushanda kwekuchengetedzwa kwemagetsi emagetsi.Pakusarudza zvinhu zvakanaka uye zvisina kunaka zvinoshanda uye diaphragm zvinhu, mugadziri haana kuitisa kumwe kuongorora pane hunhu uye kuenzanisa kwezvinhu zvakasvibirira, zvichikonzera kushomeka kwekuzvarwa mukuchengetedzwa kwesero.
(2) Matambudziko ekugadzira maitiro
Zvinhu zvakasvibirira zvesero hazvina kunyatsoedzwa, uye nzvimbo yekugadzira yakashata, zvichiita kuti kusvibiswa mukugadzirwa, izvo zvisingakuvadzi chete kukwanisa kwebhatiri, asiwo zvine simba guru pakuchengetedzwa kwebhatiri;Mukuwedzera, kana mvura yakawandisa yakasanganiswa mu electrolyte, maitiro emativi anogona kuitika uye kuwedzera kudzvinyirira kwemukati kwebheteri, izvo zvichakanganisa kuchengeteka;Nekuda kwekudzikisira kweyero yekugadzira danho, panguva yekugadzirwa kweiyo yemagetsi musimboti, chigadzirwa hachikwanise kuwana kuenderana kwakanaka, senge kushata flatness ye electrode matrix, kudonha kweiyo inoshanda electrode zvinhu, kusanganiswa kweimwe tsvina mu. iyo inoshanda, iyo isina kuchengetedzeka welding ye electrode lug, iyo isingagadzike welding tembiricha, maburrs pamucheto we electrode chidimbu, uye kusavapo kwekushandiswa kwetepi yekuisa insulating muzvikamu zvakakosha, izvo zvinogona kukanganisa zvakanyanya kuchengetedzeka kwesimbi yemagetsi. .
(3) Iyo dhizaini kukanganisa kweiyo yemagetsi musimboti inoderedza kuchengetedzwa kwekuita
Panyaya yekugadzirwa kwemaitiro, akawanda akakosha mapoinzi ane chekuita pakuchengetedza haana kupihwa hanya nemugadziri.Semuenzaniso, hapana tepi inodzivirira pazvikamu zvakakosha, hapana muganho kana kuti isina kukwana margin yakasara mudhizaini yediaphragm, dhizaini yehuwandu hwehuwandu hweakanaka uye asina kunaka maelectrode haanzwisisike, dhizaini yenzvimbo chiyero chezvakanaka uye zvisina kunaka zvinoshanda. zvinhu hazvina musoro, uye dhizaini yehurefu hwegugi haina musoro, iyo inogona kuisa njodzi dzakavanzika kune kuchengetedzwa kwebhatiri.Uye zvakare, mukugadzirwa kwesero, vamwe vagadziri vesero vanoedza kuchengetedza uye kudzvanya zvigadzirwa kuitira kuchengetedza mutengo uye kugadzirisa mashandiro, sekuderedza nzvimbo yediaphragm, kuderedza foil yemhangura, aluminium foil, uye kusashandisa pressure relief valve kana insulating tepi, iyo inoderedza kuchengetedzwa kwebhatiri.
(4) Kunyanya kuwanda kwesimba
Parizvino, musika uri kutsvaga zvigadzirwa zvebhatiri zvine huwandu hwepamusoro.Kuti vawedzere kukwikwidzana kwezvigadzirwa, vagadziri vanoramba vachivandudza huwandu hwesimba re lithium ion mabhatiri, ayo anowedzera zvakanyanya njodzi yemabhatiri.
