Zirconia-free NaSICON solid electrolyte materials for sodium all-solid-state batteries

Abstract

The growing demand for energy storage systems sparks a race to build inexpensive and safer rechargeable batteries. All-solid-state sodium (Na)-ion batteries are a competitive alternative to their lithium (Li) analogs...

Recent Advances on F-Doped Layered Transition Metal Oxides for Sodium Ion Batteries

“…Since LIBs were discovered in the 1970s and officially commercialized for powering electronic products in 1991 [8], they have achieved great success with great advantages in practical applications, but they are limited by the extremely uneven distribution and the high price of lithium ore [9]. Their electrolytes contain non-aqueous flammable organic solvents that pose a serious fire hazard in the event of thermal runaway [10]. In the 1980s, researchers discovered that Na + could be reversibly (de)inserted from NaCoO 2 layered oxides.…”
