Researchers at CIC energiGUNE have developed a method for preparing a solid polymer electrolyte with single ion-conducting properties based on modified cellulose for Li and Na batteries.
The resulting electrolyte is greener, safer, and more cost-effective. It allows the use of green, cellulose-based composite materials to improve the single ion-conducting properties, ionic conductivity, and mechanical properties of the resulting solid polymer electrolyte. Besides, this increases the cost-effectiveness of the electrolyte, since it avoids the need for adding any expensive lithium/sodium-based salts to the polymer electrolyte. Another characteristic of the invention is the non-use of any liquid plasticizer hence improving the safety aspect associated with the use of liquid electrolytes.
