Energy storage at EChem Supplies spans the chemistries researchers actually build cells around — lithium-ion and adjacent rechargeables, redox-flow stacks, and the capacitive devices that sit between batteries and dielectrics. This top-level section is the entry point to the materials, electrodes, separators, electrolytes, and cell hardware needed to assemble, characterize, and cycle storage devices on the bench, organized so that picking a chemistry leads you cleanly to the components it requires.
The section is grouped by device class — pick the chemistry first, then drill into the children for the specific component families:
-
Battery Consumables — the rechargeable-battery workflow: cathode and anode active materials across olivine, spinel, layered, and conversion-type families; PVDF and aqueous binders; conductive carbons; PFSA and polyolefin separators; lithium and sodium salts in carbonate, glyme, and ionic-liquid solvents; copper and aluminum current collectors; coin and pouch cell hardware. The starting point for lithium-ion, sodium-ion, and most solid-state work.
-
Redox Flow Battery — the flow stack as a coupled system: aqueous and non-aqueous redox couples (vanadium, iron-chromium, all-iron, zinc-bromine, organic actives), PFSA and sulfonated hydrocarbon CEMs and AEMs, carbon paper and felt flow-through electrodes, corrosion-resistant titanium and tantalum collectors, and benchtop flow fixtures for screening couple-membrane combinations.
-
Supercapacitor — the discipline node for EDLCs, pseudocapacitors, and hybrid devices: high-surface-area carbons, transition-metal-oxide and conducting-polymer pseudocapacitive materials, and the wide-window organic and ionic-liquid electrolytes that raise their energy density. Supporting hardware lives across the rest of the catalog.
If you are building a lithium-ion or sodium-ion cell, start with Battery Consumables. For stationary long-duration storage, begin in Redox Flow Battery and let the couple choice drive the rest of the stack. For high-power, long-cycle-life devices, see Supercapacitor.
