Abstract

The effects of cyclic sulfate additives including ethylene sulfate (or 1,3,2-Dioxathiolane-2,2-dioxide (DTD)), trimethylene sulfate (or 1,3,2-Dioxathiane 2,2-dioxide (TMS)) and propylene sulfate (or 4-methyl-1,3,2-dioxathiolane-2,2-dioxide (PLS)) on Li(Ni 1/3 Mn 1/3 Co 1/3 )O 2 /graphite pouch cells were studied. These additives have the same SO 4 unit bonded to a different hydrocarbon ring so that the impact of changes to the ring on the electrochemical behavior can be studied. The additives were studied in pouch cells singly and in combination with 2% vinylene carbonate (VC) using high precision coulometry, AC impedance, long term storage and using a gas evolution apparatus. DTD and TMS show significant promise as electrolyte additives while PLS appears less useful. When added alone, DTD and TMS decrease cell impedance compared to control cells, improve coulombic efficiency and reduce voltage drop during storage. However, both lead to significant gas generation, comparable to control cells, during formation. DTD in combination with 2% VC gives high coulombic efficiency (CE), stable impedance during cycling and manageable amounts of gas during formation. TMS in combination with VC produces virtually no gas during formation at 40°C. In addition, TMS in combination with VC shows high CE and impedance that is reduced during early cycling. PLS in combination with VC yields cells with relatively poor CE and impedance growth during cycling.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
