LG Chem Ltd. has completed a test flight of an unmanned plane at the highest altitude using its lithium-sulfur battery for the first time in South Korea.
The battery maker said last week that a small aircraft, dubbed EAV-3, successfully underwent a flight testing of about 13 hours in the stratosphere using the next-generation battery in Goheung, South Korea.
LG Chem loaded a lithium-sulfur battery on the EAV-3 and conducted the test-flight from 08:36 am to 09:47 pm on Aug. 30.
EAV-3 is a high-altitude long-endurance solar-powered unmanned vehicle developed by Korea Aerospace Research Institute. It can fly in the stratospheric altitude of 12km or higher using solar energy and batteries. It charges energy using a solar cell placed on the top of the wing. It has 20m-long wings and a 9m-long body.
