Perspective on recent improvements in experiment and theory towards realizing lithium metal electrodes with liquid electrolytes.
Abstract This roadmap presents the transformational research ideas proposed by “BATTERY 2030+,” European large‐scale initiative for future battery chemistries. A “chemistry‐neutral” to advance research, particularly at low technology readiness levels, is outlined, with a time horizon of more than ten years. The centered around six themes: 1) accelerated materials discovery platform, 2) interface genome, integration smart functionalities such as 3) sensing and 4) self‐healing processes....
Abstract Development of high‐performing lithium‐based batteries inevitably calls for a profound understanding and elucidation the reactivity at electrode–liquid electrolyte interface its impact on overall performance safety. The formation, composition, properties, mechanisms cathode interphase (CEI) formation function are still to large extent unknown most battery materials, whereas same is well considered solid negative electrodes in literature. In particular, high voltage regions > 4.3...
Abstract Lithium metal as a negative electrode material offers ten times the specific capacity of graphitic electrodes, but its rechargeable operation poses challenges like excessive and continuous interphase formation, high surface area lithium deposits safety issues. Improving | electrolyte interface requires powerful analysis techniques, such ToF-SIMS sputter depth profiling.This study investigates sections with an SEI layer by using different ions. An optimal ion is chosen based on...
Abstract The timely arrival of novel materials plays a key role in bringing advances to society, as the pace at which major technological breakthroughs take place is usually dictated by discovery rate are identified within chemical space. High‐throughput experimentation and computation strategy, now widely considered watershed accelerating optimization virtually every field, enables simultaneous screening, synthesis characterization large arrays different material classes toward...
Abstract Driven by the continuous search for improving performances, understanding phenomena at electrode/electrolyte interfaces has become an overriding factor success of sustainable and efficient battery technologies mobile stationary applications. Toward this goal, rapid advances have been made regarding simulations/modeling techniques characterization approaches, including high‐throughput electrochemical measurements coupled with spectroscopies. Focusing on Li‐ion batteries, current...
Thanks to its high operating voltage, the LiNi0.5Mn1.5O4 (LNMO) spinel represents a promising next-generation cathode material candidate for Lithium ion batteries. However, LNMO-based full-cells with organic carbonate solvent electrolytes suffer from severe capacity fading issues, associated electrolyte decomposition and concurrent degradative reactions at electrode/electrolyte interface, especially elevated temperatures. As alternatives, two selected LiTFSI/pyrrolidinium...
In this work, a failure mechanism of tris(trimethylsilyl)phosphite (TMSPi), as popular additive in LiPF<sub>6</sub> containing electrolyte for lithium ion batteries, is proposed and elucidated the first time.
Organic carbonate-based electrolytes blended with ionic liquids exhibit improved electrochemical properties, as demonstrated by experiments and MD simulations.
Diverse LiPF6 hydrolysis products evolve during lithium-ion battery cell operation at elevated temperatures and high voltages. However, their impact on the formation stability of electrode/electrolyte interfaces is not yet investigated understood. In this work, literature-known dimethyl fluorophosphate (DMFP) diethyl (DEFP) were synthesized characterized. The use DMFP DEFP as electrolyte additive in 1 M EC:EMC (1:1, by wt) was LiNi1/3Mn1/3Co1/3O2/Li half cells. When charged to a cutoff...
Abstract Open access to research data is increasingly important for accelerating research. Grant authorities therefore request detailed plans how managed in the projects they finance. We have recently developed such a plan EU−H2020 BIG‐MAP project—a cross‐disciplinary project targeting disruptive battery‐material discoveries. Essential reaching goal extensive sharing of across scales, disciplines and stakeholders, not limited European BATTERY 2030+ initiative but within entire battery...
Three symmetric substances originating from triethyl phosphate were specifically synthesized with varying degree of fluorination at the side chain. Different concentrations each evaluated as co-solvent regard to their flammability and electrochemical cycling performance. With higher a amount in electrolyte, self-extinguishing time (SET), value determine compare electrolytes, could be significantly lowered yield non-flammable electrolyte mixture. A designed SET device is introduced, which...
Further development of high voltage lithium‐ion batteries requires electrolyte formulations stable against oxidation or measures to generate a protective cathode/electrolyte interface (CEI) film. In the frame this work, actually counterintuitive concept using metal ions as additives stabilize CEI has proven be successful.

State-of-the-art (SOTA) liquid electrolyte/polyolefin separator setups used in lithium ion batteries (LIBs) suffer from the hazard of leakage and high flammability. To address these issues, phosphonate, a flame-retarding moiety, is chemically bonded to polymer matrix fabricate nonflammable gel electrolyte (GPE). The obtained phosphonate-based as well its corresponding GPE (gelled with flammable SOTA nonaqueous electrolyte) shows remarkable flame resistivity. Unlike poly(vinylidene fluoride-...
