    报告摘要

Rechargeable batteries are believed to play a key role in a future energy technology, where fossil resources are replaced with environmental friendly energy generation, such as wind and solar power. A large problem with such energy sources is off course that the energy is not generated when it is needed as most, i.e., day versus night and summer versus winter. Here large scale rechargeable batteries play a natural role for energy storage. Important here is off course very high capacity of the battery, low cost and good sustainability, i.e., no hazardous chemicals and no critical elements used. Lithium ion batteries are therefore not ideal for this type of applications, due to prize, but also the rareness of the element lithium. Flow cell batteries – where both charged forms are located in the electrolyte - represent an interesting alternative, since the capacitance easily can be increased, discharging is neglectable, and stability good. However, most established and suggested system, rely on elements that are sustainable problematic, such as vanadium, use toxic/cancerogenic chemicals (anthraquinone, ferricyanide) and use either organic solvents of high pH if water based. We have developed a flow cell battery based on oxidized lignosulfonate in one pool and ferric acetate on the other. The concept works at a broad pH interval and is both renewable and nontoxic. The system is stable for at least 100 charging/discharging cycles.
