“…A buffer layer such as liquid electrolytes (LE), 82 polymer solid electrolytes, 83 plastic-crystal electrolytes 84 and depositing cathode materials on LATP pellet techniques 80 was also introduced to reduce impedance resistance, especially at high mass loading of cathode active materials. Wang et al 82 employed 2 μl LE (1 M LiPF 6 in EC/DMC/ DEC) at the LiFePO 4 (LFP)/LATP interface (Figure 5A).…”

“…Although building the solid-liquid hybrid electrolyte is effective to reduce impedance resistance, the existence of liquid organic electrolyte may still bring safety risks. Yang et al 83 applied PEO adhesive as interfacial buffer layer to contact LATP SSE and LFP cathode in view of its Li + conducting ability and great compatibility with Li metal anode. Meanwhile, PEO adhesive was also employed as binder inside the cathode components (Figure 5B).…”

The replacement of liquid organic electrolytes with solid-state electrolytes (SSEs) is a feasible way to solve the safety issues and improve the energy density of lithium batteries. Developing SSEs materials that can well match with high-voltage cathodes and lithium metal anode is quite significant to develop high-energy-density lithium batteries. Li 1 + x Al x Ti 2 -x (PO 4 ) 3 (LATP) SSE with NASICON structure exhibits high ionic conductivity, low cost and superior air stability, which enable it as one of the most hopeful candidates for all-solidstate batteries (ASSBs). However, the high interfacial impedance between LATP and electrodes, and the severe interfacial side reactions with the lithium metal greatly limit its applications in ASSBs. This review introduces the crystal structure and ion transport mechanisms of LATP and summarizes the key factors affecting the ionic conductivity. The side reaction mechanisms of LATP with Li metal and the promising strategies for optimizing interfacial compatibility are reviewed. We also summarize the applications of LATP including as surface coatings of cathode particles, ion transport network additives and inorganic fillers of composite polymer electrolytes. At last, this review proposes the challenges and the future development directions of LATP in SSBs.

Solid-state batteries are one of the effective way to solve the safety of traditional power and energy storage batteries with flammable liquid electrolyte. This time, a quasi-solid-state lithium battery is assembled by plasma sprayed amorphous Li 4 Ti 5 O 12 (LTO) electrode and ceramic/polymer composite electrolyte with a little liquid electrolyte (10 μl/cm 2 ) to provide the outstanding electrochemical stability and better than normal interface contact. SEM, STEM, TEM and EDS were used to analyze the structure evolution and performance of plasma sprayed amorphous LTO electrode and ceramic/polymer composite electrolyte before and after electrochemical experiments. By comparing the electrochemical performance of the amorphous LTO electrode and the traditional LTO electrode, the electrochemical behavior of different electrodes is studied. The results show that plasma spraying can prepare an amorphous Li 4 Ti 5 O 12 electrode coating of about 8 μm. After 200 electrochemical cycles, the structure of the electrode evolved, and the inside of the electrode fractured and cracks expanded, because of recrystallization at the interface between the rich fluorine compounds and the amorphous LTO electrode. Similarly, the ceramic/polymer composite electrolyte has undergone structural evolution after 200 cycles test. The electrochemical cycle results show that the cycle stability, capacity retention rate, coulomb efficiency, and internal impedance of amorphous LTO electrodes are better than traditional LTO electrode. This innovative and facile quasi-solid-state strategy is aimed to promote the intrinsic safety and stability of working lithium battery, shedding light on the development of next-generation high-performance solid-state lithium batteries.
