According to foreign media reports, calcium-based batteries are expected to achieve higher energy densities at lower manufacturing costs, and eventually this laboratory-type technology can replace lithium-ion technology in future energy storage systems. However, with existing electrolytes, it is not possible to charge such batteries at room temperature. However, researchers at the Karlsruhe Institute of Technology (KIT) in Germany have developed a very promising electrolyte that makes rechargeable calcium batteries possible.

Efficient, large, and low-cost energy storage systems can enable society to accelerate the transition to zero-emission travel and electricity supply. However, Maxim ’s professor, Ulm and director of the CELEST research platform at the Karlsruhe electrochemical energy storage center, Maximilian Fichtner, said that the current dominant lithium-ion technology cannot achieve this task on a global scale. Therefore, scientists began to study calcium batteries and other energy storage technologies. "In the medium term, lithium-ion batteries will reach their limits in terms of performance and certain production resources, preventing them from being used for future transitional energy sources. Resources for producing lithium-ion batteries such as cobalt, nickel, and lithium are also limited." KIT An Ulm Helmholtz Institute (HIU) was established with Ulm University, and Fichtner and the research team focused on developing alternative battery technologies. Such technologies are based on abundant resources. Calcium is a very promising resource, because contrary to lithium, each calcium atom can release and absorb two electrons, and provide a voltage similar to lithium. "Calcium is the fifth most abundant element on earth, and it is evenly distributed on the earth, safe, non-toxic and cheap."

However, so far, the development of calcium batteries still faces a big obstacle. Compared with the mature lithium-ion technology or the recent sodium or magnesium battery technology, the electrolyte that can be made into rechargeable calcium batteries is still scarce. The first author of the study, Dr. Zhenyou Li, said: "In recent years, experimental electrolytes and calcium batteries have been developed. However, these electrolytes can only be charged at temperatures exceeding 75 degrees Celsius. In addition, they are also prone to adverse side effects. "

Now, researchers have successfully synthesized a new type of electrolyte based on a special organic calcium salt, which can be charged at room temperature. Using this new electrolyte, the researchers demonstrated a calcium battery with high energy density, high energy storage capacity, and quick charge.

This new electrolyte is an important basis for converting experimental calcium batteries into practically used calcium batteries. In electric vehicles, mobile electronic devices and fixed energy storage systems, such calcium batteries may one day replace the currently dominant lithium-ion batteries. (Author: Yuqiu Yun)
