Enhanced electrochemical performance of LiNi0.83Co0.12Mn0.05O2 cathodes with a fast-ion conductor Li0.33La0.56TiO3 coating layer

Yonglin Wu et al.

Summary: Ni-rich layered cathode materials LiNixCoyMn(1-x-y)O2 (x >= 0.8) suffer from capacity decay due to structural deterioration during electrochemical cycling. To overcome these problems, the fast-ion conductor Li0.33La0.56TiO3 (LLTO) is coated on the surface of LiNi0.83Co0.12Mn0.05O2 (NCM83) cathodes through the sol-gel method, which can stabilize the electrode/electrolyte interface of cathode materials and facilitate Li+ transport and charge transfer. Therefore, the fast-ion conductor LLTO coating strategy shows great potential in improving the performance of Ni-rich layered cathode materials.

Defect Chemistry and Mixed Conduction in Lithium Lanthanum Titanate During the Transition from Electrolyte to Anode Material

Joseph Ring et al.

Summary: LLTO is a promising material in Li ion battery application due to its stable ambient and high ionic conductivity. Under high Li chemical potential, LLTO undergoes a transition from an electrolyte to a high rate capable electrode material. However, the exact voltage of this transition and the electronic conductivity of reduced LLTO were unknown. In this study, we investigated the thermodynamics of lithium insertion and the ion and electron conductivity of reduced LLTO, and proposed a defect chemical model that fits well with the experimental data.

Exploring point defects and trap states in undoped SrTiO3 single crystals

Matthaeus Siebenhofer et al.

Summary: The defect chemistry and electronic trapping energies in undoped single crystalline SrTiO3 were investigated using electrochemical impedance spectroscopy and positron annihilation lifetime spectroscopy. The results showed that the chemical capacitance is a valuable tool for establishing a defect model based on electrochemical measurements and analyzing defect concentrations. The chemical capacitance analysis and positron annihilation lifetime spectroscopy are consistent in quantifying the defect concentrations in SrTiO3.

Tailoring Interfaces in Solid-State Batteries Using Interfacial Thermochemistry and Band Alignment

Robert E. Warburton et al.

Summary: Solid-state lithium ion batteries have enhanced thermal stability compared to those using liquid electrolytes, but their practical implementation is limited by undesired side reactions between the electrode and electrolyte. By using first-principles calculations and X-ray scattering experiments, molecular-level reactivity can be elucidated and design principles for tailored interfaces based on surface and interfacial properties can be developed.

Investigating the electrochemical stability of Li7La3Zr2O12 solid electrolytes using field stress experiments

Stefan Smetaczek et al.

Summary: The study shows that LLZO decomposes at 4.1-4.3 V vs. Li+/Li, forming Li-poor phases like La2Zr2O7 beneath the positively polarized electrode. This reaction continues even after several days of polarization, indicating the absence of a blocking interfacial layer. The decomposition can be observed at elevated as well as room temperature, suggesting that LLZO is truly not compatible with high voltage cathode materials.
