- In this perspective article, we review some of the most recent advances in the emerging field of organic materials as the electroactive component in solid electrodes for batteries. These comprise, but are not limited to, organometallic salts, small molecular systems, redox-active macromolecules, as well as hybrid formulations with inorganic electrode constituents. The materials are first scrutinized in terms of their general electrochemical performance and most apparent challenges, while an outlook is then made into how to best utilize them in battery electrodes and in all-organic cells. An insight into the fundamental structural-dynamic properties of these compounds, not least explored through a range of modelling and characterization techniques, is also given to complement the experimental advances. The major advantages of these materials as compared to competing technologies are most likely their potentially low environmental impact and general sustainability, which forms the context of this summary of the research field and corresponding technology area.

- An increasing demand on high energy and power systems has arisen not only with the development of electric vehicle (EV), hybrid electric vehicle (HEV), telecom, and mobile technologies, but also for specific applications such as powering of microelectronic systems. To power those microdevices, an extra variable is added to the equation: a limited footprint area. Three-dimensional (3D) microbatteries are a solution to combine high-density energy and power. In this work, we present the formation of Cu2Sb onto three-dimensionally architectured arrays of Cu current collectors. Sb electrodeposition conditions and annealing post treatment are discussed in light of their influence on the morphology and battery performances. An increase of cycling stability was observed when Sb was fully alloyed with the Cu current collector. A subsequent separator layer was added to the 3D electrode when optimized. Equivalent capacity values are measured for at least 20 cycles. Work is currently devoted to the identification of the causes of capacity fading.

Designing Quinone-based Organic Batteries
- 2021

Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- The demand for secondary energy storage is ever increasing, being at the forefront of the transformation to a sustainable society. Conventional batteries, whose electrode materials require mining and high temperature refining, generate substantial carbon dioxide emissions during production. Furthermore, the process for recycling of these batteries is difficult and still at in its infancy. On the contrary, organic batteries could be a sustainable and alternative energy storage solution and is therefore gaining increased attention. While there are several promising organic battery concepts, the focus in of this thesis has been towards batteries using quinones as capacity carrying units. Furthermore, a special emphasis was put on conducting polymers for providing conductivity within the electrode material, predominately in the form of conducting redox polymers. Several battery designs have been explored. All-organic batteries, cycling protons both with an ionic liquid and with a readily available aqueous electrolyte, have been evaluated with promising results concerning rate capabilities and low temperature operation. Hybrid-organic battery designs have shown that quinones easily cycle Lithium ions and act in a dual ion battery with a Manganese oxide cathode. This thesis therefore gives a broad overview on how quinone organic batteries can be designed and provides an outlook on how future development can be focused.

2021 roadmap for sodium-ion batteries

- Increasing concerns regarding the sustainability of lithium sources, due to their limited availability and consequent expected price increase, have raised awareness of the importance of developing alternative energy-storage candidates that can sustain the ever-growing energy demand. Furthermore, limitations on the availability of the transition metals used in the manufacturing of cathode materials, together with questionable mining practices, are driving development towards more sustainable elements. Given the uniformly high abundance and cost-effectiveness of sodium, as well as its very suitable redox potential (close to that of lithium), sodium-ion battery technology offers tremendous potential to be a counterpart to lithium-ion batteries (LIBs) in different application scenarios, such as stationary energy storage and low-cost vehicles. This potential is reflected by the major investments that are being made by industry in a wide variety of markets and in diverse material combinations. Despite the associated advantages of being a drop-in replacement for LIBs, there are remarkable differences in the physicochemical properties between sodium and lithium that give rise to different behaviours, for example, different coordination preferences in compounds, desolvation energies, or solubility of the solid-electrolyte interphase inorganic salt components. This demands a more detailed study of the underlying physical and chemical processes occurring in sodium-ion batteries and allows great scope for groundbreaking advances in the field, from lab-scale to scale-up. This roadmap provides an extensive review by experts in academia and industry of the current state of the art in 2021 and the different research directions and strategies currently underway to improve the performance of sodium-ion batteries. The aim is to provide an opinion with respect to the current challenges and opportunities, from the fundamental properties to the practical applications of this technology.
