Nickel‐rich layered oxides, such as LiNi 0.83 Mn 0.06 Co 0.11 O 2 (NMC), are among the most promising cathode materials for high‐energy‐density lithium‐ion batteries. However, their practical implementation is limited by surface instability and the presence of residual lithium compounds, which degrade performance and complicate scalability. In this study, a dual‐functional surface modification strategy using lithium dihydrogen phosphate (LiH 2 PO 4 ) is presented. A wet impregnation procedure is used to transform the residual surface contaminants (LiOH, Li 2 CO 3 ) into an advantageous surface coating (Li 3 PO 4 ) on single crystal nickel‐rich (SCNMC) cathode materials rather than directly eliminating them through solvent washing process., as confirmed by titration and in situ Gas Chromotography‐Mas (GC‐MS), while the resulting ≈4 nm Li 3 PO 4 layer enhances structural stability, suppresses nickel migration, and mitigates electrolyte‐induced side reactions. Electrochemical tests reveal significantly improved cycling stability (72.96% capacity retention after 100 cycles at 0.2C compared to 18.25% for pristine SCNMC) and enhanced rate capability, supported by improved Li + diffusion kinetics. Synchrotron X‐ray Absorption Spectroscopy (XAS) and post‐mortem analyses further confirm the preservation of Ni oxidation states and reduced cross‐talk effects.

Lithium-ion batteries are central to sustainable energy systems, yet internal short circuits (ISCs) can trigger catastrophic failures, such as fires and explosions. Current detection methods are based on costly tests, large datasets, or computationally heavy models, which limit their scalability and practical application. Here, we report a physics-based framework for the early detection of soft ISCs by representing the battery as an equivalent resistance-capacitance (RC) circuit with time-varying resistances. Using signal processing, we track periodic resistance fluctuations in charging data to identify the onset of ISCs without any abuse conditions. Fast Fourier transform (FFT) highlights distinct frequency-domain signatures, while Welch's algorithm extracts characteristic power spectral density patterns that serve as detection criteria. Together, these methods provide robust, real-time monitoring of ISC formation. Our results establish a new diagnostic standard that links microscopic ISC dynamics with macroscopic signals, significantly improving battery safety for electric vehicles, consumer electronics, and grid-scale energy storage.

Silicon is the preferred choice for lithium-ion battery anodes due to its high theoretical capacity and low lithiation potential. However, achieving high areal capacity with silicon anodes in solid-state batteries (SSBs) is challenging because of poor electronic and ionic conductivity, as well as chemo-mechanical instability at the silicon|solid electrolyte (Si|SE) interfaces. Here, we propose fabricating and testing composite anodes made of nanosized Si powder embedded in partially fluorinated graphene (Si-FG) and Li6PS5Cl (LPSCl) sulfide SE. X-ray photoelectron spectroscopy revealed that the in situ formation of LiF-rich SEI can protect against SE decomposition at the interface in the Si-FG-LPSCl composite anode. FIB-SEM and EIS analyses also indicate a stable structure and low interfacial resistance after one cycle for a composite anode containing FG. The incorporation of partially FG enhances both electronic (through heterojunction formation with Si) and ionic conductivities, buffers significant volume changes, and ensures chemo-mechanical stability in the composite anode. The Si-FG-LPSCl composite anode in SSBs delivered high discharge/charge capacities of 3499/2994 mAh g–1 at a C-rate of C/20 and an ICE of 85.6% in a half cell. This work provides valuable insights for advancing high-capacity Si composite anodes to meet future energy needs.

As interest in next-generation all-solid-state batteries (ASSBs) grows, understanding the impact of solution-based processing on solid-state electrolytes (SSEs) becomes crucial. This study examines the interaction of Li3InCl6 (LIC), a halide SSE, with various solvents, including protic, aprotic polar, and nonpolar types. LIC powder is mixed with ten solvents selected for their diverse physical and chemical properties. Through a series of analytical techniques, this study explores the compatibility of LIC with different solvent environments. The LIC–solvent mixtures are analyzed through color observation, pH measurement, and isothermal calorimetric titration. Moreover, after solvent removal, the dried LIC powder is further characterized using diffraction and various advanced spectroscopic techniques. The findings reveal that LIC is chemically stable in nonpolar solvents but exhibits instability in most polar solvents, with ethanol showing the highest stability among the polar options. It is also observed that indium reacts with highly electronegative elements such as oxygen and nitrogen based on the hard–soft acid–base principle. Furthermore, LIC in protic solvents results in acidic solutions, whereas in aprotic solvents, it exhibits basicity. These results are crucial for the development of ASSBs and underscore the importance of understanding the chemical compatibility of LIC with various solvent systems for advanced energy storage applications.

Defects in deposited lithium (Li) severely cause dendrite growth and promote reactions between Li and electrolytes, resulting in active Li loss in anode‐free Li metal batteries (AFLMBs). Herein, potassium underpotential deposition (K‐UPD) is systematically established to heal defective Li and create a K‐Cu bimetallic interface, facilitating uniform bulk Li deposition. The K‐UPD at a potential of ≈1.0 V, higher than the equilibrium potentials of bulk K⁺ (0.1 V) and Li⁺ (0.0 V), significantly lowers the nucleation barrier and mitigates Li dendrite growth due to the better lithiophilicity of K metal compared to Cu. Meanwhile, the higher surface mobility of K atoms than Li atoms enables K metal to heal defects and prevent reactions between Li and electrolytes. The lower adsorption energy (ΔE) of the K atoms (−1.56 eV) than that of Li atoms (0.032 eV) indicates favorable adsorption of the K atom, as confirmed by DFT calculations. As a result, Cu||Li cell containing 1.3 M LiFSI+0.2 M KFSI bimetallic electrolyte reaches >1600 h, while Cu||NMC532 full‐cell achieves a higher average Coulombic efficiency (avg. CE) of 99.6% than the cell with 1.5 M LiFSI electrolyte (≈98.2%) after the 100th cycle. This work offers insights into the K‐UPD mechanism for enhancing interface stability and healing defects in deposited Li.
