Liquefied gas electrolytes with unique solvation structure enable high ionic conductivity in extended temperature ranges, supporting wide-temperature high-voltage lithium metal batteries.
The reversibility of Li metal batteries suffers beneath 0 °C due to a heightened charge-transfer barrier. Herein, the introduction ion-pairs within electrolyte is shown improve this behavior, enabling hundreds cycles down −40 °C.
Improving the extremely low temperature operation of rechargeable batteries is vital to electronics in extreme environments, where systems capable high-rate discharge are short supply. Herein, we demonstrate holistic design dual-graphite batteries, which circumvent sluggish ion-desolvation process found typical lithium-ion during discharge. These were enabled by a novel electrolyte, simultaneously provides high electrochemical stability and ionic conductivity at temperature. The cells, when...
The operation of lithium-ion batteries (LIBs) at low temperatures (≤−20 °C) is limited by reduced ionic transport properties the electrolyte, as well severe charge-transfer polarization. Herein, we demonstrate that this low-temperature cycling limitation can be overcome in LiNixMnyCozO2 (x + y z = 1) (NMC)||graphite type full cells with a methyl propionate (MP)-based ester electrolyte. This consisting LiPF6 dissolved MP and fluoroethylene carbonate (FEC), delivers successful high rate 0.5C...
Abstract Confining molecules in the nanoscale environment can lead to dramatic changes of their physical and chemical properties, which opens possibilities for new applications. There is a growing interest liquefied gas electrolytes electrochemical devices operating at low temperatures due melting point. However, high vapor pressure still poses potential safety concerns practical usages. Herein, we report facile capillary condensation electrolyte by strong confinement sub-nanometer pores...
All-climate temperature operation capability and increased energy density have been recognized as two crucial targets, but they are rarely achieved together in rechargeable lithium (Li) batteries. Herein, we demonstrate an electrolyte system by using monodentate dibutyl ether with both low melting high boiling points the sole solvent. Its weak solvation endows aggregate structure solubility toward polysulfide species a relatively concentration (2 mol L-1). These features were found to be...
Abstract All‐solid‐state batteries are emerging as potential successors in energy storage technologies due to their increased safety, stemming from replacing organic liquid electrolytes conventional Li‐ion with less flammable solid‐state electrolytes. However, all‐solid‐state require precise control over cycling pressure maintain effective interfacial contacts between materials. Traditional uniaxial cell holders, often used battery research, face challenges accommodating electrode volume...
Li||SPAN batteries in the lithium bis(fluorosulfonyl)imide methyl propionate/fluoroethylene carbonate (LiFSI MP/FEC) electrolyte system can charge and discharge at −40 °C with over 78% room temperature capacity retention.
Abstract Despite significant progress in energy retention, lithium‐ion batteries (LIBs) face untenable reductions cycle life under extreme fast‐charging (XFC) conditions, which primarily originate from a variety of kinetic limitations between the graphite anode and electrolyte. Through quantitative Li + loss accounting comprehensive materials analyses, it is directly observed that operation LIB pouch cells at 4 C||C/3 (charging||discharging) results plating, disadvantageous...
Lithium fluorinated-carbon (Li/CFx ) is one of the most promising chemistries for high-energy-density primary energy-storage systems in applications where rechargeability not required. Though Li/CFx demonstrates high energy density (>2100 Wh kg-1 under ambient conditions, achieving such a when exposed to subzero temperatures remains challenge, particularly current density. Here, liquefied gas electrolyte with an anion-pair solvation structure based on dimethyl ether low melting point (-141...
Nonaqueous fluidic transport and ion solvation properties under nanoscale confinement are poorly understood, especially in conduction for energy storage conversion systems. Herein, metal-organic frameworks (MOFs) aprotic electrolytes studied as a robust platform molecular-level insights into electrolyte behaviors confined spaces. By employing computer simulations, along with spectroscopic electrochemical measurements, we demonstrate several phenomena that deviate from the bulk, including...
The future application of Li metal batteries (LMBs) at scale demands electrolytes that endow improved performance under fast-charging and low-temperature operating conditions. Recent works indicate desolvation kinetics + plays a crucial role in enabling such behavior. However, the modulation this process has typically been achieved through inducing qualitative degrees ion pairing into system. In work, we find more quantitative control is to minimizing penalty electrified interface thus...
