The battery R&D data guide
A guide for battery R&D directors, cell and materials scientists, and quality and engineering leads at battery and battery-materials manufacturers.
Battery teams explain why a cell performed as it did by connecting material, formulation, process and cell-test data in one record, instead of reconstructing the story from separate tools. The Battery R&D Data Guide is written for battery R&D directors, cell and materials scientists, and quality and engineering leads at battery and battery-materials manufacturers.
Battery development moves fast and fails expensively. A new cathode chemistry, binder or coating-thickness change can affect capacity, cycle life and safety in ways only connected data can untangle. Yet coin-cell screening, pouch-cell builds, pilot-line records, formulation data and cycler results often sit in separate tools.
Every finished cell brings together several material and process histories: cathode, anode, electrolyte, separator and assembly. A chemistry that works in a coin cell can fail at pilot scale because coating thickness, calendered density and other process variables move with cell architecture at each step. If that process context is not captured alongside the formulation, the team cannot isolate which change caused the shift.
What does the EU battery passport require?
From 18 February 2027, under Article 77 of Regulation (EU) 2023/1542, every electric-vehicle battery, light-means-of-transport battery and industrial battery over 2 kWh placed on the EU market must have a battery passport. The passport is an electronic record covering chemistry, carbon footprint, recycled content, state of health and supply chain due diligence.
That turns data fragmentation into a market-access problem, not just an R&D inefficiency. The guide shows how structured, connected R&D data can support faster development now while making traceability and reporting part of normal work.

FAQs
The EU battery passport becomes mandatory from 18 February 2027, under Article 77 of the EU Battery Regulation. Every electric vehicle battery, light means of transport battery and industrial battery above 2 kWh placed on the EU market will need an electronic record covering chemistry, carbon footprint, recycled content, state of health and supply chain due diligence.
A battery chemistry that works in a coin cell can fail at pilot scale because coating thickness, calendered density and other process variables usually change together with cell architecture at each scale-up step. If that process context isn't captured alongside the formulation, the team can't isolate which change caused the performance shift.
Battery R&D generates formulation data for cathode, anode and electrolyte; process data such as slurry solids content, coating gap and calendering pressure; electrochemical test data including capacity, Coulombic efficiency and cycle life; and characterization data such as XRD, SEM and particle size distribution. That data is most valuable when linked to the exact material and process that produced it.
Yes. Mitra Chem, which develops iron-based cathode active materials, runs its battery materials R&D on Uncountable, capturing formulation and test data in a structured, queryable system that also serves downstream traceability and reporting. For battery teams, that means one data foundation for both development work and downstream reporting.
The Battery R&D Data Guide is for battery R&D directors, cell and materials scientists, and quality and engineering leads at battery and battery-materials manufacturers. The guide covers why battery data fragments across development stages, full-cell traceability, EU battery passport readiness and three practical tests for evaluating a battery R&D data platform.
