NEI Introduces New Electrode Sheets for Aqueous Sodium-Ion Batteries

NEI Corporation has expanded its advanced materials portfolio to include a new line of standard electrode sheets designed specifically for Aqueous Sodium-Ion (Na-ion) Battery Systems.

As researchers and developers continue to explore alternative battery chemistries, aqueous sodium-ion systems are gaining attention for their inherent safety and sustainability profiles. To support the evaluation and development of these systems, we have utilized our manufacturing capabilities to introduce reliable baseline anodes and cathodes optimized for aqueous environments.

These new electrode sheets provide a high-quality, standard baseline for laboratories and developers looking to test, validate, and advance their aqueous cell designs.

Available Aqueous Sodium-Ion Compositions

Our new product line includes Sodium-ion anode and cathode sheets, cast on carbon paper optimized for aqueous environments, providing a reliable baseline for your test cells.

  • NANOMYTE® AQB-30E – Sodium Manganese Oxide (Na44MnO2)
  • NANOMYTE® AQB-31E – Alpha-Manganese Dioxide (α-MnO2)
  • NANOMYTE® AQB-61E – Iron Phosphate (FePO4)
  • NANOMYTE® AQB-64E – Olivine Sodium Iron Phosphate (NaFePO4)
  • NANOMYTE® AQB-90E – Sodium Vanadium Phosphate (Na3V2(PO4)3)
  • NANOMYTE® AQB-200CE – Carbon-coated Sodium Titanium Phosphate (NaTi2(PO4)3)

NEI Introduces Three New Battery Materials to its Product Line

June 24, 2020

Somerset, NJ (USA) – NEI Corporation recently introduced three new products, further expanding its product line of Battery Electrode Sheets. The new materials cater to the growing need in the industry for high performance cathode and anode electrodes for lithium and lithium-ion batteries.

NANOMYTE® BE-70E is a cast electrode sheet of Sublimed Sulfur powder. Sulfur cathodes offer a high theoretical capacity of 1,672 mAh/g in a Li-S cell, which is an order of magnitude higher than those of the transition-metal oxide cathodes. The high capacity is based on the conversion reaction of sulfur to form lithium sulfide (Li2S) by reversibly incorporating two electrons per sulfur atom. Li−S cell consists of a lithium metal anode, an organic electrolyte, and a sulfur composite cathode, which leads to a theoretical cell capacity of 1,167 mAh/g. BE-70E has a practical capacity of at least 800 mAh/g. The discharge reaction has an average cell voltage of 2.15 V, resulting in a high theoretical gravimetric energy density of 2,509 Wh/kg at the cell level.

NANOMYTE® BE-150E is a cast electrode sheet of Silicon-Graphite composite powder. Silicon (Si) has attracted great attention due to its remarkably high theoretical specific capacity of ~4200 mAh/g, making it one of the most potential anode materials for advancing high-energy lithium-ion batteries. Si-Graphite composite (Si-C) offers the leverage to improve the electrochemical properties of Si with excellent stability attributed to the surrounding carbon-based matrix and improved electric conductivity network. Si-C tapes showed a nominal capacity of 750 mAh/g at 0.05C (electrode loading, 4 mAh/cm2) and demonstrated excellent cycling stability at 0.2C rate.

NANOMYTE® BE-400E is a cast electrode sheet of Niobium Oxide powder (Nb2O5), which is a new electrode material with pseudocapacitive charge storage being introduced to the market for the first time as a potential anode material. It is capable of exceptionally high rate charge as well as discharge (6 – 10C), with good cycling stability (1,000 – 3,000 cycles) and minimal heat generation during high-rate charge-discharge. The unique architecture of the oxide material enables rapid lithium diffusion on a macro and micro-scale enabling enhanced rate performance.

NEI offers a variety of cathode and anode electrode sheets, suitable for a wide range of Lithium-ion battery applications. Standard electrode sheets are cast single-side on 5″ x 10″ foil current collectors, and are available in ready-to-ship packages of 2, 5, and 10 sheets (per material). For customers with specific needs, tape specifications such as the active material loading, coating thickness, binder type (aqueous/non-aqueous), binder content, or current collector can be modified.
