Cost-effective test rigs for metal-free batteries preparing for equity raising and industrialization

Important results from the project

All project objectives were met, but not within the specified timeframe and the project had to be extended. All stack test rigs were built, and sensors have been installed. Electrolytes for testing have been manufactured and a successful test has been performed. Other important results of the project have been that the project has promoted dialogues with customers, investors and suppliers, and enabled a revised development plan for Rivus.

Expected long term effects

The test results from the stacks will provide key technical verification for future investment rounds – crucial for Rivus’ continued development. In addition, the results enable collaborative projects with hardware vendors, where their BMS and EMS systems can be optimized based on Rivus SoC-kurvor and viscosity data. Finally, the project strengthens Rivus’ future sales, as the tests provide data on long-term stability – a key factor in demonstrating the reliability of the technology.

Approach and implementation

A meeting was held where the first stack test rigs was designed based on experiences from Rivu´s first pilot battery. Components for four rigs were purchased, but only the first rig was built. Installing pumps, bushings and hoses went without a problem, and pressure sensors for the flow also worked. Gas sensors and making the rigs gas-tight for nitrogen gas were also challenging, and several iterations of seals were tried. The schedule was not met, and the project had to be extended.
