“…Experimental data showed that the resistance of the LCO/LATP interface was 400 Ω cm 2 after deposition, but it increased to 9750 Ω cm 2 after annealing at 500 °C (measured at 50 °C). [207] Similar results were observed for LiMn 0.5 Ni 0.5 O 2 [208] and NMC111 [209] deposited on top of crystalline LATP layers. The interface resistance increased strongly with increasing annealing temperature, for example, a value of about 1000 Ω cm 2 at 50 °C was determined for the LiMn 0.5 Ni 0.5 O 2 interface after annealing at 300 °C.…”

[ 208 ] The initial discharge capacity of this system was low (<100 mAh g −1 ), which was attributed to insufficient cation ordering caused by the low annealing temperature. [ 208 ] Similar cells with as‐deposited LCO [ 207 ] and NMC111 [ 210 ] thin films showed higher initial capacities.…”

This review discusses the contribution of physical vapor deposition (PVD) processes to the development of electrochemical energy storage systems with emphasis on solid‐state batteries. A brief overview of different PVD technologies and details highlighting the utility of PVD for the fabrication and characterization of individual battery materials are provided. In this context, the key methods that have been developed for the fabrication of solid electrolytes and active electrode materials with well‐defined properties are described, and demonstrations of how these techniques facilitate the in‐depth understanding of fundamental material properties and interfacial phenomena as well as the development of new materials are provided. Beyond the discussion of single components and interfaces, the progress on the device scale is also presented. State‐of‐the‐art solid‐state batteries, both academic and commercial types, are assessed in view of energy and power density as well as long‐term stability. Finally, recent efforts to improve the power and energy density through the development of 3D‐structured cells and the investigation of bulk cells are discussed.

The charge transfer reaction at the LiNbO 3 -coated LiCoO 2 /sulfidebased solid electrolyte interface was investigated with a Ni microelectrode. A two-electrode cell was assembled and two electrochemical measurements were performed in order to evaluate exchange currents at various temperatures and activation energy for charge transfer reaction (E CT ) for positive electrode material. E CT at the LiNbO 3 -coated LiCoO 2 / solid electrolyte interface was evaluated to be 48 kJ mol -1 . This value was smaller than E CT at the LiCoO 2 /organic electrolyte interface. In case of Li metal negative electrode, it has already found that E CT at the Li metal/solid electrolyte interface is smaller than E CT at the Li metal/organic electrolyte interface due to the lack of a desolvation process. Similar to this, it was demonstrated that the charge transfer reaction at the LiCoO 2 /solid electrolyte didn't contain the desolvation process.

“…Oxide impurities form at the interface of LLT and LiCoO 2 cathode with sintering, creating high interfacial resistance that dominates cell behavior, while LiMnO 4 was shown to form a low resistance interface with LLT. Similarly, the formation of the inert oxide layer increases the LiNi 0.5 Mn 0.5 O 2 /LATSP interfacial resistance, blocking the Li ion diffusion through the interface (Xie et al 2010). Li 7 La 3 Zr 2 O 12 (LLZ) was calcined to obtained garnetlike structure pellet that in a symmetric Li cell showed interfaced stability, reversible plating and de-plating with no reaction.…”

From aqueous liquid electrolytes for lithiumair cells to ionic liquid electrolytes that permit continuous, high-rate cycling of secondary batteries comprising metallic lithium anodes, we show that many of the key impediments to progress in developing next-generation batteries with high specific energies can be overcome with cleaver designs of the electrolyte. When these designs are coupled with as cleverly engineered electrode configurations that control chemical interactions between the electrolyte and electrode or by simple additives-based schemes for manipulating physical contact between the electrolyte and electrode, we further show that rechargeable battery configurations can be facilely designed to achieve desirable safety, energy density and cycling performance.
