BEIJING, Jan. 7 (Xinhua) — A new fundamental science experiment involving lithium-ion batteries was conducted aboard China's Tiangong space station, the Dalian Institute of Chemical Physics of the Chinese Academy of Sciences said Wednesday.
The experiment, conducted by three crew members of the Shenzhou 21 spacecraft, aimed to uncover the mechanisms underlying battery operation under the unique conditions of space.
Lithium-ion batteries are essential for modern space missions due to their high energy density and reliability. However, as the aforementioned institute explained, under terrestrial conditions, it is difficult to fully understand their internal behavior, particularly how chemicals are distributed within the electrolyte, which critically impacts power output and service life.
"The main problem with experiments on Earth is gravity," the institute stated. "Gravity is constantly intertwined with electric fields, making it difficult to determine its influence on the internal processes in batteries."
In contrast, the microgravity conditions on the space station provide an ideal environment for observing these processes without the interference of gravity.
The institute emphasized that the findings from the experiment, conducted in microgravity conditions, are expected to overcome existing limitations in understanding the interaction between gravitational and electric fields.
These results will help improve existing battery systems in orbit and develop a new generation of safer, higher energy density batteries for future space exploration. -0-
