Service - battery cell prototyping & testing
Solid Energies Inc. (SEI) helps battery developers and product teams turn material concepts into testable cells and functional battery packs. Our services connect materials engineering, prototype fabrication, testing, and manufacturing development so you can evaluate performance, resolve design challenges, and prepare for scale-up.
Battery Cell/Pack Prototyping
Compare materials and cell designs in formats suited to the stage of development. Coin cells support early screening; custom pouch cells support multi-Ah (up to 50Ah) development and application-focused evaluation.
Service Scope
Electrode Preparation Slurry preparation, (slot-die/doctor blade) coating, drying, calendering, die cutting
Electrolyte Integration Liquid, gel, semi-solid, all-solid-state systems, subject to material compatibility
Cell Assembly Stacking, tab welding, electrolyte filling, sealing, formation, and degassing
Moisture Management Dry-room processing, with dew-point requirements defined for the chemistry
Pack integration Cell packing, thermal management/modeling, BMS, packaging
Battery Cell Testing and Validation
Build a test plan around the decisions your team needs to make, from material selection and cell benchmarking to pack design verification.
Service Purpose
Cycle life and calendar aging Track capacity, energy, resistance, and degradation under defined conditions.
DCIR and HPPC Evaluate resistance and pulse-power behavior across operation conditions
Rate and temperature mapping Characterize performance across selected charge, discharge, and temperature conditions (-70 deg C to +120 deg C)
Electrochemical impedance
spectroscopy Investiagte resistance and interfacial changes in materials/cells.
Safety and abuse evaluation Nail penetration, overcharge, external short circuit, thermal-storage tests with suitable sample and facilities
Cell testing up to 400A on 5V channels is subject to configuration, duty cycle, and sample requirements. Pack testing is scoped separately; temperature conditions must match the sample and equipment limits. Agree to test methods and acceptance criteria before testing. Product certification is a separate scope.
