Explorations of solid-state lithium metal batteries (SLMBs) with high-performance hybrid polymer electrolytes are the demand for the development of novel energy storage systems with enhanced safeties and high theoretical energy...

A highly conductive and stable hybrid solid electrolyte for high voltage lithium metal batteries

“…Fig. 3a shows the temperature dependence of the Li + conductivity of different HSEs (with LiTFSI), and the 15,16,33,37,[39][40][41][42][43][44][45][46][47] Our work exhibits high voltage stability and ionic conductivity (for details see Table S4 The lithium transference number (t Li…”

Lipoic Acid-Assisted In Situ Integration of Ultrathin Solid-State Electrolytes

“…Prominent charging and discharging plateaus were extracted from the curve with a charging rate of 0.1 C, and the voltage plateaus were about 3.47 and 3.38 V. The over-potential was about 0.09 V. In addition, with the increase of the current density, the discharge voltage plateau decreased gradually. The obtained results demonstrate satisfactory electrochemical performances of LA-SSE due to the blocking effect of this high-strength electrolyte for suppressing the growth of lithium dendrites during the cycling and consequently decreasing the short-circuit risk. − …”

Fiber-reinforced quasi-solid polymer electrolytes enabling stable Li-metal batteries

“…[17][18][19][20] Solid electrolytes, including inorganic solid electrolytes and solid polymer electrolytes, have been considered as more promising candidates to inhibit the Li dendrite growth and address the safety issues of LMBs. [21][22][23][24][25] Generally, an ideal solid electrolyte should possess high ionic conductivity, good mechanical strength, and an intimate electrode/electrolyte interface. [26][27][28] Nevertheless, the low ionic conductivity (much lower than that of a liquid electrolyte) and poor electrode/electrolyte contact severely impede their practical applications.…”
