MIMI TECH GMBH

Their core work

MIMI Tech GmbH is an Aachen-based technology SME specializing in advanced battery materials and next-generation energy storage systems. Their work sits at the intersection of materials science and battery engineering — contributing to both cobalt-free cathode chemistries and solid-state electrolyte development. In practice, they operate as a specialist technology partner in large research consortia, bringing focused materials or engineering expertise to projects targeting the electric vehicle and stationary storage markets. Based in Aachen, a city with deep ties to battery and e-mobility research through RWTH, they are well-positioned within Germany's advanced manufacturing and energy transition ecosystem.

What they specialise in

How they've shifted over time

MIMI Tech's H2020 participation spans 2019–2024 across just two projects, but a clear thematic shift is visible. Their earlier engagement (CoFBAT) centered on cobalt-free cathode materials for stationary storage — a chemistry-driven problem motivated by cost, supply-chain risk, safety, and end-of-life recyclability. Their more recent project (SUBLIME) moves decisively into solid-state electrolyte technology for electric vehicles, targeting Generation 4b battery performance with lithium-metal anodes and high energy density. The trajectory is from sustainable chemistry (cobalt reduction, recycling) toward high-performance solid-state architectures for mobility — reflecting the broader market pull of EV battery development in Germany.

MIMI Tech is moving deeper into solid-state battery R&D for electric vehicles, making them a relevant partner for consortia targeting Generation 4b or post-lithium-ion battery platforms.

How they like to work

MIMI Tech has participated in H2020 exclusively as a consortium partner, never as a project coordinator — a pattern consistent with a focused specialist rather than a project orchestrator. Both projects are RIA (Research and Innovation Actions), suggesting they contribute technical expertise to collaborative research rather than leading commercial demonstration work. With 32 unique partners across 11 countries from just 2 projects, they operate within large, internationally distributed consortia typical of EU battery research programs.

MIMI Tech has built a network of 32 unique consortium partners across 11 countries through just two projects — a relatively broad reach for a small SME, reflecting the large-consortium nature of EU battery research. Their geographic footprint spans at least 11 European countries, though no data points to a specific regional concentration beyond their German base.

What sets them apart

MIMI Tech is a rare SME operating at the research frontier of two parallel next-generation battery tracks — cobalt-free chemistries and sulfide solid-state electrolytes — rather than focusing on a single technology bet. Their Aachen location places them near one of Europe's most active battery research clusters, giving them proximity to RWTH and related industrial networks. For consortium builders, they offer SME flexibility combined with materials-level depth that is harder to find in larger industrial partners.

Highlights from their portfolio

• SUBLIME
  Targets Generation 4b solid-state lithium-metal batteries for EVs — one of the most technically ambitious battery chemistries in the EU research pipeline, with MIMI Tech contributing to sulfide electrolyte and high-energy-density cell development.
• CoFBAT
  The larger of the two grants (€342,525) and notable for addressing both stationary storage and industrial robotics applications with cobalt-free materials — a multi-market approach rarely seen in single battery projects.
