Ford favoring bulk-type solid-state battery for next-gen energy storage

Green Car Congress

Ford is exploring a variety of “beyond Li-ion” solutions, including Lithium-sulfur, Lithium-air and solid-state lithium-ion batteries. A Li-air battery, with its air cathode, is a low-cost system, Anandan said. It also offers a high theoretical specific energy density.

Researchers develop robust biopolymer network binder enabling high sulfur loading in Li-S electrodes

Green Car Congress

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.
