“We replaced lithium with copper”: these sodium batteries boosted in manganese could reverse the industry

Technological advances in the field of batteries represent a crucial issue for the future of renewable energies. In addition, A recent study highlights an innovative method developed by Japanese scientists, which could transform the Sodium-ion battery industry (NA-ion). For example, Using manganese oxides, these researchers have managed to improve both the performance and sustainability of these batteries. Nevertheless, This promising discovery could open “we replaced lithium copper”: these the way to a broader adoption of renewable energies. Moreover, offering a viable and economical alternative to lithium-ion batteries (Li-ion).

Manganese oxides: a promising solution – "we replaced lithium copper": these

Manganese oxides are distinguished as a lasting solution for the development of NA-ion batteries. In addition, According to Professor Shinichi Komaba of the University of Sciences of Tokyo. In addition, The relatively low costs of manganese and sodium make this search an advance towards more affordable energy storage solutions. These solutions could apply to various areas, such as smartphones and electric vehicles, thus contributing to a more sustainable future.

The researchers highlighted two crystalline forms of the Namno2: the α phase and the β phase. The α phase presents a monoclinical structure in layers, while the β phase is characterized by corrugated layers. The synthesis of the β phase requires high temperatures, often resulting in sodium deficient phases.

Severe capacity reduction problem solved – "we replaced lithium copper": these

A major problem with β-Namno2 electrodes is the severe reduction in capacity during load/discharge cycles. which limits their practical use. Superposition defects. formed by the shift in the crystallographic plan, complicate the understanding of the chemistry of the solid of this material. However, researchers have discovered that copper doping “we replaced lithium copper”: these (Cu) can stabilize the β-namno2 phase by removing these defects.

This approach makes it possible to significantly improve the electrochemical performance of the electrodes, making the NA-ion batteries more reliable. The results published in the Advanced Materials newspaper show that the electrodes doped at the CU do not have a degradation of capacity over 150 cycles. stressing their robustness and their reversibility.

Implications for the supply chain

Stabilization of superposition defects using Cu could. also resolve the vulnerabilities of the supply chain linked to metals such as lithium. This advance is particularly relevant in the current context of energy transitionwhere lithium resources are limited and costly. The implications of this study extend to energy storage for electrical networks, as well as electric vehicles and consumer electronics.

In addition. the use of more abundant and less expensive materials could reduce dependence on rare and expensive metals, while promoting the development of a greener and durable economy.
