All-solid-state Li-ion batteries with metallic Li anodes and solid electrolytes could offer superior energy density and safety over conventional Li-ion batteries. However, compared with organic liquid electrolytes, the low conductivity of solid electrolytes and large electrolyte/electrode interfacial resistance impede their practical application. Garnet-type Li-ion conducting oxides are among the most promising electrolytes for all-solid-state Li-ion batteries. In this work, the large-radius Rb is doped at the La site of cubic LiGaLaZrO to enhance the Li-ion conductivity for the first time. The LiGaLaRbZrO electrolyte exhibits a Li-ion conductivity of 1.62 mS cm at room temperature, which is the highest conductivity reported until now. All-solid-state Li-ion batteries are constructed from the electrolyte, metallic Li anode, and LiFePO active cathode. The addition of Li(CFSO)N electrolytic salt in the cathode effectively reduces the interfacial resistance, allowing for a high initial discharge capacity of 152 mAh g and good cycling stability with 110 mAh g retained after 20 cycles at a charge/discharge rate of 0.05 C at 60 °C.

“…Since interfacial resistance from poor contact (Figure 2D) is proven to be the main reason for the high internal resistance of solid state lithium batteries (Park et al, 2016; Han et al, 2017), quite a few approaches have been applied to reduce interfacial resistance, including co-sintering (Wakayama et al, 2016), in-situ synthesized electrolyte layer (Yoshima et al, 2016; Kazyak et al, 2017), interface buffer layers (Kato et al, 2014; Park et al, 2016), interface softening (Seino et al, 2011; Sakuda et al, 2012; Liu et al, 2016), surface coating (Han et al, 2017), and amorphous cathode (Matsuyama et al, 2016; Nagao et al, 2017) etc.…”

Solid state lithium batteries are widely accepted as promising candidates for next generation of various energy storage devices with the probability to realize improved energy density and superior safety performances. However, the interface between electrode and solid electrolyte remain a key issue that hinders practical development of solid state lithium batteries. In this review, we specifically focus on the interface between solid electrolytes and prevailing cathodes. The basic principles of interface layer formation are summarized and three kinds of interface layers can be categorized. For typical solid state lithium batteries, a most common and daunting challenge is to achieve and sustain intimate solid-solid contact. Meanwhile, different specific issues occur on various types of solid electrolytes, depending on the intrinsic properties of adjacent solid components. Our discussion mostly involves following electrolytes, including solid polymer electrolyte, inorganic solid oxide and sulfide electrolytes as well as composite electrolytes. The effective strategies to overcome the interface instabilities are also summarized. In order to clarify interfacial behaviors fundamentally, advanced characterization techniques with time, and atomic-scale resolution are required to gain more insights from different perspectives. And recent progresses achieved from advanced characterization are also reviewed here. We highlight that the cooperative characterization of diverse advanced characterization techniques is necessary to gain the final clarification of interface behavior, and stress that the combination of diverse interfacial modification strategies is required to build up decent cathode-electrolyte interface for superior solid state lithium batteries.

“…To solve the point-to-point contact problem of the cathode/oxide solid-state electrolyte interface and increase the interfacial contact area, the following four strategies have been proposed. The first strategy involves the use of advanced deposition techniques such as chemical vapor deposition, 77 pulse laser deposition (PLD), 78,79 atomic layer deposition (ALD), 80 and magnetron sputtering 81,82 to deposit oxide a solid-state electrolyte thin film onto the cathode or to coat the cathode material onto the oxide solid-state electrolyte pellet. These deposition techniques can guarantee excellent interfacial conformability between the cathode and the oxide solid-state electrolyte and increase the contact area at their interface to the maximum extent.…”

Security risks of flammability and explosion represent major problems with the use of conventional lithium rechargeable batteries using a liquid electrolyte. The application of solid-state electrolytes could effectively help to avoid these safety concerns. However, integrating the solid-state electrolytes into the all-solid-state lithium batteries is still a huge challenge mainly due to the high interfacial resistance present in the entire battery, especially at the interface between the cathode and the solid-state electrolyte pellet and the interfaces inside the cathode. Herein, recent progress made from investigations of cathode/solid-state electrolyte interfacial behaviors including the contact problem, the interlayer diffusion issue, the space-charge layer effect, and electrochemical compatibility is presented according to the classification of oxide-, sulfide-, and polymer-based solid-state electrolytes. We also propose strategies for the construction of ideal next-generation cathode/solid-state electrolyte interfaces with high room-temperature ionic conductivity, stable interfacial contact during long cycling, free formation of the spacecharge region, and good compatibility with high-voltage cathodes.
