Organic Cathode Materials for Secondary Batteries

Background

With increasing efforts put into sustainable development, the need for the efficient storage of energy obtained with renewable energy sources is on the rise. Since established battery technologies rely on the use of lithium and precious transition metals, organic cathode materials are fast becoming a hot topic in battery research. But despite rapid developments in this area, we are still facing a lack of materials with good electrochemical performance that can be obtained by means of facile synthesis.

Description of invention

Our novel organic cathode materials are based on a combination of redox-active pyrazine and quinone motifs, which boast high energy density and stability. They are obtained by means of facile synthesis, where a part of the components is sourced from biomass. The synthesized materials boast a broad range of applications, with the possibility of combining them with various mono- and multivalent anodes as well as organic and water-based electrolytes.

Main advantages

• High energy density and stability.
• Low utilization of rare transition metals.
• Facile and energy-efficient synthesis, where a part of the components is
  sourced from biomass.
• Versatile applicability in different secondary battery systems with various
  mono- and multivalent electrodes.
• Compatibility with organic and water-based electrolytes, which represents an
  important.
