Purchase energy storage batteries for reuse

ECO STOR recently signed an MoU with Nissan, Norsk Gjenvinning and Agder Energi to reuse EV batteries in energy storage and recycle spent batteries. In addition, it has established a German subsidiary, ECO STOR GmbH, that offers grid-connected energy storage solutions using new batteries.

The strategy is applied to various reuse scenarios with capacity configurations, including energy storage systems, communication base stations, and low-speed vehicles. Hydrometallurgical, pyrometallurgical, and direct recycling considering battery residual values are evaluated at the end-of-life stage.

To mitigate these risks, scientific and industrial communities advocate for the reuse and recycling of retired batteries 11, 12. Reuse aims to extend the useful lifetime of batteries, lower the investment and operational costs of energy systems, and minimize the demand for raw materials.

The price advantage of used batteries could be overshadowed by the declining cost of new batteries. Consequently, it is essential to comprehensively assess the economic value of reused batteries for storage of solar energy.

Reuse and recycling of retired electric vehicle (EV) batteries offer a sustainable waste management approach but face decision-making challenges. Based on the process-based life cycle assessment method, we present a strategy to optimize pathways of retired battery treatments economically and environmentally.

Applications in the reuse phase include energy storage systems (ESSs), communication base stations (CBSs), and low-speed vehicles (LSVs). When the batteries are subjected to the EOL stage, pretreatment and three recycling technologies are considered, including hydrometallurgical, direct, and pyrometallurgical recycling.
