Carbon Footprint and Footprint Family of Electrolytes in Solid-State Batteries
In recent years,with the global climate change,promoting carbon neutrality has become a global consensus.Solid-state batteries have become the only way to develop batteries in the future due to their advantages such as high safety,high energy density,and wider operating temperature range.Electrolytes are the main part of the carbon footprint of batteries.In this paper,a total of 22 types of solid electrolytes,including inorganic,polymer,and composite electrolytes,were selected as the research objects.Their carbon,water,material,ecological,and health footprints were simulated and calculated,respectively.The results show that the footprint impact values of composite solid electrolytes,inorganic solid electrolytes,and polymer solid electrolytes generally follow the rule of decreasing in order.The composite solid electrolyte has the highest footprint impact value among all footprint categories,and electrolytes made from different inorganic compounds can impact the environment more.
