Swedish developer Altris and renewable products provider Stora Enso have joined forces to advance Stora Enso’s hard carbon solution, Lignode, as an anode material in Altris’ sodium-ion battery cells. This partnership aims to bolster the development of environmentally friendly batteries without compromising on energy density, while enhancing the European battery supply chain.
Altris’ sodium-ion battery technology is crafted from abundant raw materials, eliminating the need for conflict minerals and toxic elements like lithium, nickel, and cobalt. These batteries offer exceptional performance, including longer lifespan, flexible working temperatures, and enhanced safety.
Lignode, developed by Stora Enso, is a sustainable hard carbon material derived from lignin, a by-product of pulp manufacturing. It serves as a greener alternative to existing anode solutions, utilizing trees that can be replenished, ensuring a stable and consistent supply for anode manufacturing.
The collaboration with Stora Enso marks a significant step in Altris’ product development journey. In 2023, the company unveiled a commercial-sized sodium-ion battery cell boasting an energy density of 160 Wh/kg. This milestone was achieved through the use of Altris’ patented Prussian White cathode material, which has a capacity exceeding 160 mAh/g – the highest capacity declared to date in a Prussian White cathode material solely derived from abundant raw materials.
