Dry Cells

Dry cells let you lock the electrode stack, separator, and packaging chemistry before you ever touch electrolyte — so you can study formation, wetting, and SEI/CEI growth as deliberate variables instead of confounding noise. Every unit in this collection is a fully assembled pouch cell that has been vacuum-dried and heat-sealed, but not yet activated. You inject the electrolyte you want to test, perform your own formation cycle, and degas under your own protocol.

The collection is organised by chemistry family so you can match the cell to your research question.

Lithium-ion full cells

• Layered NCM // Si/C and NCM // Li — high-nickel layered oxides (NCM811, NCM9055) paired with silicon-carbon composite anodes for high-energy-density work, or with lithium metal for benchmarking cathode-side losses.
• Layered LCO // Si/C — for high-voltage cathode studies and electrolyte oxidation work above 4.4 V.
• Olivine LFP // Li and anode-free LFP // Cu — long-life olivine cathode against lithium metal, or against a bare copper current collector for anode-free lithium-plating studies.
• Lithium-rich layered (LMR-NCM) // Li — for voltage-fade, oxygen-redox, and high-capacity cathode research.

Sodium-ion full cells

• NASICON polyanion (NVP, Na3V2(PO4)3) // Hard Carbon and NVP // Al/C — open-framework NASICON cathode for fast-charge work; the anode-free Al/C variant exploits sodium's stability against aluminium at low potentials.
• Polyanion pyrophosphate (NFPP, Na2FeP2O7) // Hard Carbon and NFPP // Al/C — strong P-O covalent framework for thermally stable, low-cost SIB research; available as a conventional HC anode cell or as an anode-free configuration plating sodium directly onto carbon-coated aluminium.
• Layered oxide NFM (NaNi1/3Fe1/3Mn1/3O2) // Hard Carbon — the SIB analogue of an NCM-style layered oxide cell, useful for direct LIB-to-SIB processing comparisons.
• Prussian Blue analogue // Hard Carbon — open-framework hexacyanoferrate cathode on Al current collectors (sodium does not alloy with Al), well suited to sustainability-focused chemistries.

If you are studying electrolyte formulation, SEI/CEI evolution, or formation protocols, start with a dry cell whose electrode pair matches your target system and inject in your glovebox. For anode-free or lithium-metal plating studies, choose the Cu-foil or Li-metal variants. For broader battery materials and assembly hardware, see Battery Consumables and Energy Storage.
