Future of Energy Storage: Zn and Ni-Based Batteries


In the ever-evolving landscape of energy storage, Zn (zinc) and Ni (nickel) based batteries are emerging as powerful contenders. As renewable energy sources continue to grow in prominence, the need for efficient, reliable, and sustainable battery technologies becomes increasingly critical. The Coursera course, "Zn and Ni-Based Batteries," offers a comprehensive dive into this exciting field, providing insights into the chemistry, technology, and future applications of these batteries.

Understanding Zn and Ni-Based Batteries

Zinc-Based Batteries: Zinc-based batteries, including zinc-air and zinc-ion varieties, are celebrated for their high energy density, low cost, and environmental friendliness. Zinc-air batteries, in particular, utilize oxygen from the air as a reactant, significantly reducing material costs and weight. They are being explored for various applications, from hearing aids to large-scale energy storage systems.

Nickel-Based Batteries: Nickel-based batteries, such as nickel-cadmium (NiCd) and nickel-metal hydride (NiMH), have been long-standing players in the battery market. NiMH batteries are widely used in hybrid vehicles and portable electronic devices due to their good energy density and longer life cycle compared to NiCd batteries. Nickel batteries are known for their robustness and reliability, making them suitable for demanding applications.
