New Electrolyte
TexPower is cooperating with University of Texas at Austin to develop electrolytes that enhance the strongest combination of TexPower NMA cathode and Ultra Density advanced anodes, such as High-Silicon and Lithium Metal, to bring cell energy densities beyond 500 Wh/kg.

High-nickel layered oxide cathode materials, in particular the cobalt-free LiNiO2, are the most promising candidates for developing lithium-ion batteries and lithium-metal batteries (LMBs) because of their high energy density and low cost. However, LiNiO2 suffers from poor cycling stability due to high surface reactivity and severe structural changes during cycling.

New electrolytes will allow formation of an inorganic-rich cathode-electrolyte interphase on LiNiO2 cathode, protecting its surface from degrading into rock salt and spinel phases during cycling. In addition, such electrolytes form a thin, robust solid-electrolyte interphase on Li-metal anode, alleviating the increase in overpotential during cycling. Protecting the surface is key to improving the cycling stability of LiNiO2.

High-Energy Anodes

TexPower NMA cathode is compatible with all types of advanced anodes. We have tested our cathode with Lithium Metal, 100% Graphite, Low-Silicon Graphite and High-Silicon Graphite.

High-Energy Density Battery Cells

TexPower NMA cathode provides extreme flexibility for any battery form factor.

We have tested our cathode materials with multiple cell systems, including liquid, semi-solid and solid electrolytes. NMA cathode is also positively susceptive to surface coating treatment, including advanced methods such as Atomic Layer Deposition coatings.
