Lithium metal is the best anode candidate for high energy density batteries because it has a very high theoretical specific capacity of 3861 mAh g−1 compared to 372 mAh g−1 of the carbon anode in lithium-ion batteries. Unfortunately, lithium anode have encountered the follow problems: (i) Side-reaction between lithium metal and liquid electrolyte, giving rise to electrolyte consumption, interface resistance increase and capacity loss during cycling; (ii) Safety hazards caused by dendrite formation during cycling. All-solid-state lithium polymer batteries are of great interest due to their high energy density and shape variability. High ionic conductivity at room temperature and suitable mechanical property along with important technological advantages are related to safety and electrochemical stability makes it attractive compared to liquid electrolyte which is used in commercially Li-ion batteries. In this talk, we will discuss the challenges and our recent progresses in all-solid-state lithium polymer batteries.
