Molten salt batteries are a class of battery that uses molten salts as an electrolyte. They offer both a high energy density and a high power density. Traditional non-rechargeable thermal batteries can be stored in their solid state at room temperature for long periods of time before being activated by heating.

Researchers at MIT and elsewhere have developed a new kind of battery, made entirely from abundant and inexpensive materials, that could help to fill the gap for economical, large-scale backup systems for renewable energy sources. The new battery architecture uses aluminum and sulfur as its two electrode materials, with a molten salt electrolyte in between.

How they work?

A molten salt battery uses a molten salts electrolyte. The battery is initially heated to 180°C, turning the molten salt electrolyte to liquid and allowing ions to flow through, creating chemical energy. The battery is then cooled to room temperature, turning the electrolyte into a solid, freezing the energy-carrying ions in place and locking in the energy. During activation, the cathode, anode, and electrolyte layers separate due to their relative densities and immiscibility.

The battery works by having a positive electrode (usually antimony) and a negative magnesium electrode separated by a thin layer of paper that has been soaked in a formula.

What are some advantages of Molten salt Batteries?

Some advantages of molten salt batteries include higher current density due to the liquid components, longer cycle life, simplified manufacturing scheme in large scale applications, safety, life cycles comparable to those of lithium, easy to dispose of and recycle, and use of readily available materials.

One key advantage of molten salt batteries is their high temperature operation. This allows for greater efficiency in the conversion of energy, as well as the ability to store energy in the form of heat, which can then be converted back into electricity as needed. Another major advantage is their scalability. They can be used in a wide range of applications, from small-scale residential systems to large-scale grid storage projects. This makes them a versatile and cost-effective solution for energy storage

Huawei Responds to European Commission’s Recommendation to Exclude its Equipment from EU Market

Image
Huawei has responded to the European Commission's recommendation to exclude its advanced wireless equipment from the European Union market, calling it "discriminatory." The Shenzhen-based telecom company released a statement after the EU's executive branch issued guidelines urging member countries to remove high-risk vendors, including Huawei and ZTE, from their telecom networks. Huawei stated that this decision was "not based on a verified, transparent, objective and technical assessment of 5G networks" and warned that "restrictions or exclusions based on discriminatory judgments will pose serious economic and social risks." This decision by the Commission follows the US's actions in preventing Huawei from using a range of American technologies and pressuring the EU to take a stronger stance against Beijing amid escalating conflicts over Taiwan and technological dominance. Removing Huawei from EU operations could significantly decrease Chinese...
