“…54−56 After cycling for 70 cycles at 0.1 C, capacity retention was 98.8, 99.9, 96.3, and 94.4% for cells with Aquivion-87-EC− DMA, Aquivion-98-EC−DMA, Aquivion-87-EC−PC, and Aquivion-98-EC−PC electrolytes, respectively. The resulting LFP|Li cell performance at room temperature is comparable to existing literature data for other single-ion conducting polymer electrolytes, 21,26,57 and for cells with liquid electrolytes, 53,58 which indicates the possibility of using the investigated membranes as electrolytes in lithium metal batteries.…”

Gel-polymer electrolytes based on perfluorinated cation-exchange membranes are promising electrolytes for lithium metal batteries due to the strength and chemical stability of the fluorinated matrix and high values of ionic conductivity and cation transference numbers, which contribute to the suppression of dendrite formation. The present work compares the main characteristics of polymer electrolytes based on short-side-chain membranes Aquivion-87 and Aquivion-98 with different numbers of functional groups and content of polar aprotic solvents (mixtures of ethylene carbonate−propylene carbonate and ethylene carbonate−N,N-dimethylacetamide), i.e., ionic conductivity, transference numbers, and stability against lithium metal. Electrochemical characteristics of the electrolytes in Li|Li and LiFePO 4 |Li cells show good compatibility and functionality with the Li metal anode, forming a stable Li/electrolyte boundary, and LFP| Aquivion-87-EC-DMA|Li cell shows discharge capacity values of ∼142 mAh/g at 0.1 C and 136 mAh/g at 1 C and room temperature, with a 98.8% capacity retention after 70 cycles at 0.1 C. These data indicate their promising application as polymer electrolytes in lithium metal batteries.

“…The reversibility of the charge and discharge reactions in the cathode and anode determines the reversibility of the LIBs. The chemical reaction in a conventional LIBs (with graphite carbon as the anode material and LiFePO 4 as the cathode material) can be simply summarized as [35] Anode : 6C + xLi + + xe − ↔ Li x C 6 (1) Cathode : LiFePO 4 ↔ Li 1−x FePO 4 +xLi + +xe −…”

Aqueous zinc ion battery (AZIBs) has attracted the attention of many researchers because of its safety, economy, environmental protection, and high ionic conductivity of electrolytes. However, the battery greatly suffers from zinc dendrite produced by zinc metal anode leading to poor cycle life and even unsafe problems, which limit its further development for various important applications. It is known that the success of the commercialization of lithium‐ion batteries (LIBs) is mainly due to replacement of lithium metal anode with graphite, which avoids the formation of Li dendrite. Therefore, it is an important step to develop aqueous zinc ion anode to replace conventional zinc metal one with zinc‐metal free anode material. In this review, the working principle and development prospect of “rocking‐chair” AZIBs are introduced. The research progress of different types of zinc metal‐free anode materials and cathode materials in “rocking‐chair” AZIBs is reviewed. Finally, the limitations and challenges of the Zn metal‐free “rocking‐chair” AZIBs as well as solutions are deeply discussed, aiming to provide new strategies for the development of advanced zinc‐ion batteries.

“…Additionally, the transition towards sustainable mobility hinges on advancements in efficient energy storage. Among the most common cathode materials for lithium-ion batteries are the lithium transition metal oxides of the LiMO 2 family (M = Co, Ni, Mn,…) and the lithium manganese spinel LiMn 2 O 4 [2][3][4]. Decades of study have revealed some significant drawbacks of these cathodes when applied in lithium-ion devices: (1) the transition metal oxides are prone to structural instability during cycling, leading to safety issues, and (2) the lithium manganese spinel reacts with liquid electrolytes.…”

“…The inherent stability of the FePO 4 framework makes extracting oxygen atoms more challenging compared to other oxide cathode materials, ensuring excellent thermal stability up to 400 • C [12]. However, at lower temperatures, LFP materials exhibit insufficient capacity due to several factors: (1) the olivine structure restricts Li + diffusion along the (010) direction, resulting in low ionic conductivity [13]; (2) the absence of a continuous FeO 6 network leads to low electronic conductivity [14]; and (3) the phase-transforming lithiation-delithiation process during cycling impacts battery performance under severe/extreme conditions, resulting in the formation of unwanted phases, as mentioned previously [13].…”

There are still essential aspects regarding cathodes requiring a comprehensive understanding. These include identifying the underlying phenomena that prevent reaching the theoretical capacity, explaining irreversible losses, and determining the cut-off potentials at which batteries should be cycled. We address these inquiries by investigating the cell’s capacity, and phase dynamics by looking into the transport properties of electrons. This approach underlines the crucial role of electrons in influencing battery performance, similar to their significance in other materials and devices such as transistors, thermoelectrics, or superconductors. We use LFP as a case study to demonstrate that understanding the electrochemical cycling behavior of a battery cell, particularly a Li//LFP configuration, hinges on factors like the total local potentials used to calculate chemical potentials, electronic density of states (DOS), and charge carrier densities. Our findings reveal that the stable plateau potential difference is 3.42 V, with maximum charge and minimum discharge potentials at 4.12 V and 2.80 V, respectively. The study illustrates the dynamic formation of metastable phases at a plateau voltage exceeding 3.52 V. Moreover, we establish that determining the working chemical potentials of elements like Li and Al can be achieved through a combination of their work function and DOS analysis. Additionally, we shed light on the role of carbon black beyond its conductivity enhancement. Through Density Functional Theory (DFT) calculations and experimental methods involving Scanning Kelvin Probe (SKP) and electrochemical analysis, we comprehensively examine various materials, including Li, C, Al, Cu, LFP, FePO4, Li0.25FePO4, polyvinylidene fluoride (PVDF), and Li6PS5Cl (LPSCl). The insights derived from this study, which solely rely on electrical properties, have broad applicability to all cathodes and batteries. They provide valuable information for efficiently selecting optimal formulations and conditions for cycling batteries.
