Wannan batu na lithium ya riga ya yi magana game da tsohuwar rayuwa. Mun yi taƙaitaccen taƙaitaccen taƙaitaccen juriyar lithium na yau da kullun. Gabaɗaya, ana amfani da ƙarfe Li foda da alƙalamin Li foil don aiwatar da fasahar tonifying mara kyau, kuma a halin yanzu ita ce madaidaiciyar hanyar da kamfanin kera batirin lithium-ion ke amfani da shi, amma batutuwan aminci da tsadar kayayyaki sune matsalolin da Metal Li lys ke fuskanta.

Sabanin haka, tsayin daka mai kyau na tsarin lithium yana da kyau, baya canza tsarin da ake ciki, amma balagaggen fasaha yana da ƙananan, kuma masu samar da kayan aiki masu dacewa za su kaddamar da samfurori masu dacewa.

Ta hanyoyi biyu don ƙara lithium wuce haddi a cikin ingantaccen kayan lantarki, na farko shi ne cewa a cikin tabbataccen kayan lantarki da ke ƙunshe da halayen electrochemical, tabbataccen abin lantarki yana samuwa gabaɗaya zuwa wani batir mai ƙarfi, kuma ana haɗa kayan lantarki mai inganci.

Ingantattun kayan lantarki daga nan kuma ana samun su zuwa jimlar baturi a cikin janareta mara kyau, ta yadda za a samu lithium. Wannan hanya tana da sauƙi mai sauƙi, kuma yana yiwuwa a sarrafa adadin da aka saka a cikin Li, wanda ya dace don amfani a cikin dakin gwaje-gwaje, amma rashin amfani kuma ya bayyana a fili, aikin ya fi rikitarwa, kuma babu wani amfani mai amfani a cikin ainihin mashin. Wata hanya ita ce ƙara LI mai yawa ta hanyoyin sinadarai.

Kodayake wahalar fasaha tana da girma, kar a ƙara ƙarin matakai a cikin sarrafa baturi, don haka ƙarin ƙimar aiki. Manufar tabbataccen pre-lithium daga Jamus Giuliogabrielli et al, Giuliogabrielli ya ruwaito karo na farko ta hanyar sinadarai a karon farko ta hanyar sinadarai, amma Giuliogabrielli yana da kyawawa don haɗa Li1 + XNi0.5Mn1.

Bayan wuce gona da iri na tsarin caji na farko, kayan Li1 + XNi0.5Mn1.5O4 an canza su zuwa Li1 + XNi0 na al&39;ada.

5MN1.5O4 abu da lin0.5Mn1.

5MN1.5O4 kayan ta hanyar sarrafa ma&39;auni daban-daban. Kayan abu yana gauraye, wanda zai iya sarrafa daidaitaccen rabo na Li, wanda gaba daya ya rama mummunan wutar lantarki a cikin iyawar da za a iya jujjuyawa yayin aiwatar da caji na farko, wanda kuma shine bidi&39;a da ci gaba na ingantaccen haɓakawa.

Giuliogabrielli kira na Li1 + XNi0.5Mn1.5O4 abu shine hanyar haɗin sinadarai, kuma a cikin haɗin kayan, an ƙara alkalami a cikin tsarin haɗin gwiwa, don haka ya fi dacewa, wanda yake da tasiri don magance farkon yadda ya dace na batir lithium-ion SiOx.

Hanya. Duk da haka, wuce haddi LI da aka kara zuwa tabbatacce abu da kuma samar da wani barga tsarin, da kuma tabbatar da cewa sake zagayowar yi na kayan ba wani tasiri, Xiaobian kuma godiya da duk articles buga ta Giuliogabrielli, kuma bai gani Giuliogabrielli Hanyar da ake amfani da a wasu kayan (misali, NCA da NCM kayan), wanda kuma nuna hanyar daga gefe, bai dace da duk tabbatacce electrode kayan. Vanchiappanaravindan daga Indiya ya gano cewa ana iya amfani da wannan hanyar akan kayan LIVPO4F.

Hanyar Vanchiappanaravindan shine ingantacciyar hanyar shigar da sinadarai na lantarki, wato, LIVPO4F ya fara shiga baturi, wanda ke sanya Li + ya saka kayan LIVPO4F. An kafa Li1.26VPO4F, sa&39;an nan kuma an rarraba baturi, Li1.

26VPO4F, da kuma mummunan lantarki abu (A-Fe2O3 aiki), ta yin amfani da Li1.26VPO4F abu don rama ga A-Fe2O3 abu a cikin na farko biyu lithium tsari The wadanda ba reversible iya aiki (game da 503mAh / g), ƙwarai kara habaka da makamashi yawa na dukan baturi. Koyaya, matakan yakamata su fara samar da rabin tantanin halitta.

Yin amfani da electrochemical tsarin kula da saka Li + a cikin tabbatacce abu, don haka a zahiri ainihin amfani da muhimmancin a cikin ainihin aiki, don haka m zai ci gaba da gano yadda za a wuce da sinadaran hanya madaidaiciya kira lithium wuce haddi LI1.26VPO4F abu, gane tabbatacce tonic. Kyakkyawan pre-lithium shine hanya mai kyau don magance SiOx korau electrode kuma yana haɓaka ƙarfin ƙarfin batirin lithium ion baturi, amma don shigar da wuce haddi LI a cikin ingantacciyar wutar lantarki da kuma kula da tsayayyen tsari, yana fuskantar babban kalubale, saboda haka tabbataccen pre-lithium na yanzu Ya zama dole a mai da hankali kan LIMN2O4 da Lini0.
