EV battery anode grade niobium oxide 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 , with good cycling stability 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.
The Global EV battery anode grade niobium oxide market accounted for $XX Billion in 2022 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2023 to 2030.
Recent Advances in Titanium Niobium Oxide Anodes for High-Power Lithium-Ion EV Batteries
Benefiting from the advantages of cost-effectiveness and sustainability, lithium-ion batteries (LIBs) are recognized as a next-generation energy technology with great development potential.
Herein, niobium oxide hydrate (H3ONb3O8) synthesized by a facile and inexpensive solvothermal method is proposed as the anode of LIBs. It is a layered two-dimensional material composed of negatively charged two-dimensional lamellae and positively charged interlayer hydronium ions.
The former consist of NbO6 octahedral units connected by bridging oxygen. Because of the mutual effect of hydronium ions and niobium oxide quantum dots, niobium oxide hydrate exhibits excellent electrochemical activity when used as an anode material.
This compound is first applied to lithium-ion batteries, obtaining a high specific capacity (1232 mAh g–1) at 100 mA g–1 and maintaining an outstanding performance after 200 cycles.
Therefore, this work not only proposes a simple preparation method of niobium oxide hydrate but also expands the variety of high-performance anode materials.
Battery material provider Echion Technologies and niobium supplier CBMM have formed a partnership to build a new facility in Araxá, Brazil to supply anode-grade niobium oxides to be used in Echion´s XNO battery anode material.
