Innovations in Lithium-Ion Battery Technology
Researchers at the National Institute of Technology Rourkela (NIT Rourkela) have made strides in making lithium-ion batteries for electric vehicles (EVs) more affordable and efficient. They have introduced a new class of cathode materials utilizing magnesium as an alternative to the traditional cobalt-based designs.
Key Challenges with Cobalt-Based Cathodes
- Cost and Price Volatility:
- Cobalt is expensive and subject to price fluctuations.
- Limited Availability:
- Major sources are concentrated in countries such as Cuba, Madagascar, and Papua New Guinea.
- Ethical Concerns:
- Issues surrounding the extraction processes and their impact on the environment and communities.
Need for Alternative Materials
With the growing demand for EVs and lithium-ion batteries, the reliance on cobalt presents significant issues. It is projected that by 2050, the global cobalt supply might fall short of meeting demand, highlighting the necessity for developing alternative materials.
