Developed by China's Southeast University, the device will be sent to the Taishan base by Chinese icebreaker "Xuelong" in November to start trial runs as the first domestically-made "battery" of its kind.

Its creators say the unattended power source is expected to boost energy resources to help with research at the Taishan station.

China's fourth Antarctic research station, the Taishan base, named for one of China's five sacred mountains, sits at an altitude of 2,600 metres. It has to endure an average annual temperature of minus 36.6 degrees Celsius.

The harsh natural environment means Chinese researchers need to use mechanical &remote controls, rather than manual duties at the station, thus making an unattended power supply key to the base's daily operations.
