The reporter learned from the University of Science and Technology of China on the 28th that Professor Jipeng and postdoctoral Xiao Xu of the school have made important progress in the research of Mars atmospheric batteries-proposing a Mars battery.

According to the introduction, the battery uses the atmospheric composition of Mars (simulation refers to the proportion ratio of atmospheric composition on Mars) as the reaction fuel material of the battery, which can achieve high energy density and long cycle performance.

Relevant research results were recently published in Science Bulletin (Science Bulletin).

Mars has a complex natural environment, including various gas components and severe temperature fluctuations. Based on this, the team proposed a Mars battery, which is unique in that it directly sucks into Mars atmosphere as fuel during discharge, greatly reducing the weight of the battery, it provides convenience for carrying into space. When the power is exhausted, the battery can be recharged using the solar energy on the surface of Mars to prepare for the next discharge.

The team also simulated the environment on the surface of Mars based on the temperature fluctuation and realized the Mars battery system that can continuously output electric energy.

Research shows that at a low temperature of 0 degrees Celsius, the energy density of the battery is as high as 373.9 watt hours per kilogram, and the charge-discharge cycle life is as long as 1375 hours, it means that the battery can be used on Mars for about 2 Mars months.

The team also increased the effective reaction area of Mars atmosphere to the greatest extent through integrated electrode preparation and folding battery structure design. And enlarge the size of cell to 4 square centimeters, further improving soft Pack Battery the energy density reaches 765 watt-hour per kilogram and 630 watt-hour per liter.

The team introduced that this study provided proof of concept for the application of Mars batteries in the actual Mars environment., I hope to further develop solid-state Mars batteries in the following research to lay a foundation for the development of multi-energy complementary energy systems in future space exploration.
