Abstract

A cow hair-based porous biochar for positive electrodes of lithium-sulfur batteries. The cow hair-based porous biochar includes carbon ranging from 85% to 95% by weight of the biochar and oxygen ranging from 5% to 15% by weight of the biochar. The carbon is arranged in a three-dimensional matrix defining a porosity for the biochar, and the porosity ranges from 60% to 80% of the total volume of the biochar. A synthesis process for obtaining said cow hair-based porous biochar, a cow hair-based composite active material for the preparation of positive electrodes for lithium-sulfur batteries, a positive electrode for a lithium-sulfur battery, and a method for preparing said positive electrode are also provided.
