Lithium ribbon (0.75 mm thick, Sigma‐Aldrich), lithium nickel manganese cobalt oxide (LiNixMnyCozO2, x : y : z=1 : 1 : 1, NMC111, MTI Corporation), 1 M lithium hexafluorophosphate (LiPF6) solution in ethyl carbonate (EC) and dimethyl carbonate (DMC) mixture (EC:DMC 1 : 1, v/v) (LP30, Sigma‐Aldrich), N‐methyl‐2‐pyrrolidine (NMP, anhydrous, >99 %, Sigma‐Aldrich) and dimethyl carbonate (DMC, anhydrous, >99 %, Sigma‐Aldrich) were stored in an Ar‐filled glovebox (O2<0.1 ppm, H2O<0.5 ppm) and used as received. Lithium cobalt (III) oxide (LiCoO2, LCO) was purchased from MTI Corporation and calcined at 800 °C in air, then stored in the glovebox prior to use. Super P conductive carbon black (C45, MTI Corporation), poly(vinylidene fluoride) binder (PVDF, MTI Corporation, >99.5 %, Mw∼600,000 g/mol), tetrahydrofuran (THF, 99.5 %, anhydrous, stabilized, ACROS Organics), aluminum oxide (Al2O3, 99 %, ACROS Organics), N,N‐dimethylformamide (DMF, 99.8 %, Alfa Aesar), acetonitrile (ACN, 99.7 %, spectrophotometric grade, Alfa Aesar) and dimethyl sulfoxide‐d6 (DMSO‐d6, 99.9 % atom D, Cambridge Isotope Laboratories) were stored in ambient conditions and used without further purification. Diethyl ether (anhydrous, ACS reagent, ACROS Organics) was stored at 2–8 °C.

Discharged and dismantled EoL Samsung battery cathodes were kindly supplied by Wesley Chang, Princeton University. Lithium cobalt(iii ) oxide (LiCoO2, LCO), lithium manganese oxide (LiMn2O4, EQ-Lib-LMO), and lithium nickel manganese cobalt oxide (LiNixMnyCozO2, x : y : z = 1 : 1 : 1, NMC 111) were purchased from MTI Corporation and calcined at 600 °C in air prior to use. Super P conductive carbon black (C45), graphite powder (carbon content >99.5%), and poly(vinylidene fluoride) binder (PVDF, >99.5%) were purchased from MTI Corporation and used as received. Isosorbide dimethyl ether (DMI, Sigma Aldrich, >99%), N-methyl-2-pyrrolidine (NMP, anhydrous, >99%, Sigma-Aldrich), dimethyl carbonate (DMC, Sigma Aldrich, >99%), 1 M lithium hexafluorophosphate (LiPF6) solution in ethyl carbonate (EC), dimethyl carbonate (DMC) mixture (EC : DMC 1 : 1, v/v) (LP30, Sigma-Aldrich), dimethyl sulfoxide-d6 (DMSO-d6, 99.9% atom D, Cambridge Isotope Laboratories), and deuterated water (D2O, 99.9% atom D, Cambridge Isotope Laboratories) were commercially purchased, stored at ambient conditions, and used without further purification. Diethyl ether (anhydrous, ACS reagent, ACROS Organics) was stored at 2–8 °C.

Coin cells were made with Li[Ni0.33Mn0.33Co0.33]O2 (NMC111)
as the positive electrode (cathode) and graphite as a negative electrode
(anode). NMC111 powder was obtained from MTI Corporation (particle
size, D50 = 9.0–12.0 μm). The electrode formulation
was 94 wt % active material, 3 wt % poly(vinylidene fluoride) (PVDF)
binder (MTI), and 3 wt % super P conductive carbon. Electrode materials
and n-methyl pyrrolidone solvent (NMP) were mixed
in a planetary mixer (Thinky, USA) at 2000 rpm for 10 min. The resulting
ink was coated onto aluminum foil using an automatic thick-film coating
machine (MTI) and dried at 120 °C in a vacuum oven overnight.
The cathode had a mass loading of 22.4 mg/cm2, corresponding
to an areal capacity of about 3.1 mA h/cm2.
The anode
was composed of graphite (MTI, TB-17), carbon black, oxalic acid (EMD
Millipore Corporation), and PVDF binder at a weight ratio of 85:5:0.5:9.5.
A similar slurry coating process was used to prepare the anode film
on copper current collectors. The anode had a mass loading of 12.8
mg/cm2, corresponding to an areal capacity of about 3.4
mA h/cm2.

About PubCompare
Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.
We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.
However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
