I vores erfaring er det mest kritiske trin i forberedelsen af ​​arbejdet elektroden gøre gode slam med konsistens. Som vist i figur 4, kan overskydende NMP i opslæmningen resultere i en revnet coating, medens utilstrækkelig NMP kan resultere i en porøs coating. I det foreliggende arbejde her, CR2032 knapcellebatteri tilfælde, der er 20 mm i diameter anvendes. Det skal bemærkes, at knapcellebatteri tilfælde af forskellige størrelser kan anvendes, hvor elektroden størrelser skal varieres i ov...

construction and testing of coin cells of lithium ion batteries

Genopladelige lithium ion batterier har bred anvendelse inden for elektronik, hvor kunderne altid kræve større kapacitet og længere levetid. Lithium-ion batterier er også blevet anset for at være brugt i elektriske og hybride køretøjer 1 eller endda elektriske grid systemer til stabilisering af 2. Alle disse applikationer simulere en dramatisk stigning i forskning og udvikling af batteri materialer 3-7, herunder nye materialer 3,8, doping 9, nanostrukturering 10-13, belægninger eller overflademodifikationer 14-17 og nye bindemidler 18. Derfor har et stigende antal fysikere, kemikere og materialer forskere for nylig vovede sig ind i dette område. Coin celler er meget udbredt i forskningslaboratorier til at afprøve nye batteri materialer, selv for forskning og udvikling som er rettet mod store og high-power applikationer, der er lille mønt celler ofte bruges til at teste kapaciteten og sats evnernye materialer i den indledende fase. I 2010 startede vi en National Science Foundation (NSF) sponsoreret forskningsprojekt at undersøge overfladeadsorption og disordering i batteri materialer (ikke give. DMR-1.006.515). I den indledende fase af dette projekt, har vi kæmpet for at lære de teknikker til montage og test mønt celler, som ikke kan opnås uden talrige hjælp fra andre forskere i andre universiteter (gennem hyppige opkald, e-mail udvekslinger og to besøg på stedet). Derfor føler vi, at det er fordelagtigt at dokumentere, både tekst og video, en protokol at samle og teste en mønt celle, som vil hjælpe andre nye forskere på dette område. Denne indsats repræsenterer de &quot;bredere effekt&quot; aktiviteter i vores NSF projekt, og det vil også bidrage til at uddanne og inspirere de studerende. I denne video artiklen, dokumentere vi en protokol til at samle et CR2032 mønt celle med en LiCoO2 arbejder elektrode, en Li modelektrode,og (det mest almindeligt anvendte) polyvinylidenfluorid (PVDF) bindemiddel. For at sikre nye studerende til let at gentage protokollen, holder vi den protokol som specifikke og eksplicitte som vi kan. Men det er vigtigt at bemærke, at i bestemte forsknings-og udviklingsarbejde, mange parametre, der blev vedtaget her, kan varieres. For det første kan man foretage mønt celler af forskellige størrelser og teste arbejdselektroden mod en modelektrode end Li. Sekund, mængderne af C sort og bindemiddel tilsat til de arbejdende elektroder ofte varieres for at passe til særlige formål forskning, for eksempel, blev store mængder af C sort eller endog inert pulver tilsat til arbejdselektroden at teste &quot;intrinsic&quot; præstation til billedrør materialer 14. For det tredje bedre bindemidler, bortset PVDF) har også udviklet og brugt 18. Endelig kan andre typer elektrolytter (i stedet for LiPF 6) kan også anvendes, faktisk vil visse højspænding elektrodematerialer kræver anvendelse af specielle electrolytes 7.
