Towards a Stable Organic Electrolyte for the Lithium Oxygen Battery
Bibliographic record
Abstract
A new lithium‐ether‐derived chelate ionic liquid is synthesized to serve as an electrolyte for the Li‐O 2 battery that is stable to metallic lithium, and whose ethereal framework is much more inherently stable to superoxide‐initiated hydrogen abstraction than the simple glyme, dimethoxyethane (DME). Reactions of chemically generated superoxide with this electrolyte show that virtually no decomposition products such as lithium formate are generated. When the electrolyte is employed in a Li‐O 2 battery, a ten‐fold decrease in CO 2 evolution is evident on charge by comparison to DME and greatly enhanced cycling stability is observed with TiC as a cathode support. A mechanism is proposed to account for the lowered reactivity, offering new insight into the stability of organic electrolytes in Li‐O 2 batteries. This approach for electrolyte design is presented here for the first time, and it can be extended to other organic systems to provide a platform for the design of advanced electrolyte systems.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
