Yintoni i-lithium crystal kwibhetri ye-lithium?
Xa ibhetri ye-lithium-ion ihlawuliswa, i-Li + i-deintercalated kwi-electrode efanelekileyo kwaye idibene kwi-electrode engalunganga; kodwa xa ezinye iimeko ezingaqhelekanga: ezifana nokungonelanga kwe-lithium intercalation space kwi-electrode engalunganga, ukuxhathisa kakhulu kwi-Li + intercalation kwi-electrode engalunganga, i-Li + de-intercalates ukusuka kwi-electrode echanekileyo ngokukhawuleza, kodwa ayikwazi ukuxutywa kwisixa esifanayo. Xa kusenzeka izinto ezingaqhelekanga ezifana ne-electrode engalunganga, i-Li+ engakwaziyo ukumiliselwa kwi-electrode engeyiyo inokufumana ii-electron kuphela kumphezulu we-electrode engalunganga, ngaloo ndlela yenze into yesilivere-mhlophe yentsimbi ye-lithium, edla ngokubizwa ngokuba yimvula yelithium. iikristale. Uhlalutyo lwe-lithium alunciphisi ukusebenza kwebhetri kuphela, lunciphisa kakhulu ubomi bomjikelo, kodwa lunciphisa umthamo wokutshaja okhawulezayo webhetri, kwaye lunokubangela iziphumo eziyingozi njengokutsha kunye nokudubula. Esinye sezizathu ezibalulekileyo ezikhokelela kwimvula ye-lithium crystallization bubushushu bebhetri. Xa ibhetri ijikelezwe kwiqondo lokushisa eliphantsi, i-crystallization reaction ye-lithium precipitation inezinga elikhulu lokuphendula kunenkqubo ye-lithium intercalation. I-electrode engalunganga ixhomekeke ngakumbi kwimvula phantsi kweemeko eziphantsi kobushushu. Lithium crystallization reaction.
Indlela yokusombulula ingxaki yokuba ibhetri ye-lithium ayikwazi ukusetyenziswa kwiqondo lokushisa eliphantsi
Kufuneka uyilwe iinkqubo yokulawula ubushushu bebhetri ekrelekrele. Xa ubushushu be-ambient buphantsi kakhulu, ibhetri iyafudumala, kwaye xa ubushushu bebhetri bufikelela kuluhlu olusebenzayo lwebhetri, ukufudumeza kumisiwe.
