Project abstract

The lithium ion battery (LIB) is arguably the most powerful battery technology known to date and the high energy density can be traced to the high redox potential difference between the anode and the cathode material. High energy batteries hence rely on electrolytes that are stable over a wide potential interval and on electrode material that are compatible with the cycling chemistries associated with such electrolytes, e.g. lithium- sodium- and ammonium cycling. High power capability is achieved by the use of thin (100 µm) layers of active materials and conductivity additives in the electrode formulation.

We have previously shown that the use of conducting redox polymers (CRPs) as active electrode materials makes conductivity additives in the electrode formulation redundant because these materials show metallic conductivity. Removal of conductivity additives in the electrode formulation significantly simplify the electrode formulation as well as increase the relative amount of active material in the battery. Moreover, we have shown that quinone-type materials are compatible with a multitude of cycling chemistries, including the above-mentioned lithium- sodium- and ammonium cycling.

In this project we explore the possibility to use quinone-based CRPs for several different cycling chemistries including lithium, sodium, potassium, zink, ammonium, calcium, manganese and XXX. Structural-functional relationships will be identified with particular focus on how the substitution pattern on the quinones and the relative position of the hydroxide groups affect the compatibility with different cycling ions. Based on this information CRPs will be developed and complete battery cells be assembled and evaluated with respect to cycling stability, voltage output, coulombic efficiency and rate capability.

Summary of work

The redox chemistry of 14 substituted quinones has been investigated in a total of 8 different electrolytes in order to investigate the compatibility with different cycling chemistries, including lithium, sodium, potassium, zink, ammonium, calcium and manganese. In order to understand substitution effects as well as effects of cycling ion on the quinone electrochemistry a computational study has been undertaken.

Based on quinone compatibility with manganese cycling CRPs specifically designed to function as anode material in manganese secondary batteries has been developed. Complete polymer-manganese batteries have been constructed and their performance evaluated. The study was published in ChemElectroChem in 2020.
