This study, published in the RSC journal Energy & Environmental Science , identifies a new way to obtaining high-energy-density batteries by the simple application of robust network biopolymer binders that are inherently low-cost and environmentally friendly. Both biopolymers are non-toxic, low cost, sustainable natural products.
