A research team from DGIST’s (President Kunwoo Lee) Division of Energy & Environmental Technology, led by Principal Researcher Kim Jae-hyun, has developed a lithium metal battery using a “triple-layer solid polymer electrolyte” that offers greatly enhanced fire safety and an extended lifespan. This research holds promise for diverse applications, including in electric vehicles and large-scale energy storage systems.

Conventional solid polymer electrolyte batteries perform poorly due to structural limitations which hinder an optimal electrode contact.

This could not eliminate the issue of “dendrites” either, where lithium grows in tree-like structures during repeated charging and discharging cycles.

Dendrites are a critical issue, as an irregular lithium growth can disrupt bat...

Fast radio bursts are brief and brilliant explosions of radio waves emitted by extremely compact objects such as neutron stars and possibly black holes. These fleeting fireworks last for just a thousandth of a second and can carry an enormous amount of energy—enough to briefly outshine entire galaxies.

Since the first fast radio burst (FRB) was discovered in 2007, astronomers have detected thousands of FRBs, whose locations range from within our own galaxy to as far as 8 b...

A joint research effort has developed a high-performance self-charging energy storage device capable of efficiently storing solar energy. The research team has dramatically improved the performance of existing supercapacitor devices by utilizing transition metal-based electrode materials and proposed a new energy storage technology that combines supercapacitors with solar cells.

The paper is published in the journal Energy.

The research team designed the electrodes using a nickel-based carbonate and hydroxide composite material and maximized the conductivity and stability of the electrodes by ...

NASA’s upcoming Artemis II mission is slated to return astronauts to the moon no sooner than April 2026. Astronauts were last on the moon in 1972 during the Apollo 17 mission.

Artemis II will utilize NASA’s Space Launch System, which is an extremely powerful rocket that will enable human space exploration beyond Earth’s atmosphere. The crew of four will travel in an Orion spacecraft, which the agency launched around the moon and successfully returned during the Artemis I mission.

But before Artemis II, NASA will send two missions to scout the surface of the lunar south pole for resources that could sustain human space travel and e...
