Chii mhedzisiro yekuchaja 18650 lithium-ion bhatiri munzvimbo yakaderera tembiricha?
Kuchaja mabhatiri e-lithium-ion munzvimbo dzakaderera-tembiricha kunounza dzimwe njodzi dzekuchengetedza.Izvi zvinodaro nekuti pamwe nekudzikiswa kwekunyorova, iyo kinetic properties ye graphite negative electrode inofambira mberi nekuderera muchikamu chekuchaja, electrochemical polarization ye negative electrode inowedzera zvakanyanya, kunaya kwe lithium metal kunowanzoita pakuumbwa kwe lithium. dendrites, kusimudzira diaphragm uye nekudaro kukonzera kupfupika kweiyo yakanaka uye yakaipa electrodes.Sezvinobvira kudzivirira lithium-ion bhatiri kuchaja pane yakaderera tembiricha.
Tichifunga nezve tembiricha yakaderera, iyo yakaipa electrode pane nested lithium-ion bhatiri ichaonekwa ion makristasi, anogona kubaya zvakananga diaphragm, mumamiriro ezvinhu akajairika achaita kuti micro-short circuit inokanganisa hupenyu uye kushanda, iyo yakanyanya kuoma inogona kuputika!
Zvinoenderana neane mvumo nyanzvi yekutsvagisa: lithium-ion mabhatiri kwenguva pfupi munzvimbo yakaderera-tembiricha, kana tembiricha iri kure nekudzikira, inongokanganisa kwechinguva bhatiri kugona kwemabhatiri e-lithium-ion, asi haizoburitse kukuvara zvachose. .Asi kana ikashandiswa kwenguva yakareba munzvimbo yakaderera-tembiricha, kana mu -40 ℃ ultra-low tembiricha nharaunda, lithium-ion mabhatiri anogona kuita chando kukonzeresa kukuvara zvachose.
Iyo yakaderera-tembiricha yekushandiswa kwemabhatiri e-lithium-ion inotambura nekushomeka kwesimba, kuora kwakanyanya, kushata kutenderera kwekuwandisa kuita, yakanyatso kutaurwa lithium precipitation, uye unbalanced lithium de-embedding.Zvisinei, pamwe chete nekuenderera mberi kwekuvandudzwa kwekushandiswa kukuru, zvipingamupinyi zvinounzwa nehurombo hushoma hwekushisa kwemabhatiri e-lithium-ion zviri kuwedzera uye zvakanyanya kuoneka.Munzvimbo inorema-basa rendege, heavy-duty, mota dzemagetsi nemimwe minda, bhatiri rinodiwa kuti rishande nemazvo pa -40°C.Nokudaro, kuenderera mberi kwekuvandudza kwepasi-kupisa zvinhu zvemabhatiri e-lithium-ion kune zvakakosha zvakakosha.
Ehe saizvozvo,kana yako 18650 lithium bhatiri ine zvinhu zvakaderera-tembiricha, inogona kuramba ichichajwa kazhinji munzvimbo yakaderera-tembiricha.
