POSTECH Professor Byoungwoo Kang’s research team uncovers a new Li-ion battery electrode material that can achieve high-energy density and high power capability per volume without reducing particle size.

With Telsa in the lead, the electric vehicle market is growing around the world. Unlike conventional cars that use internal combustion engines, electric cars are solely powered by lithium ion batteries, so the battery performance defines the car’s overall performance...

Worldwide efforts to make sodium-ion batteries just as functional as lithium-ion batteries have long since controlled sodium’s tendency to explode, but not yet resolved how to prevent sodium-ions from ‘getting lost’ during the first few times a battery charges and discharges. Now, researchers made a sodium powder version that fixes this problem and holds a charge properly.

Most of today’s batteries are made up of rare lithium mined from the mountains of South America. If the world depletes this source, then battery production could stagnate...

Lattice architecture can provide channels for effective transportation of electrolyte inside the volume of material, while for the cube electrode, most of the material will not be exposed to the electrolyte. The cross-section view shows the silver mesh enabling the charge (Li+ ions) transportation to the current collector and how most of the printed material has been utilized.

Additive manufacturing, otherwise known as 3D printing, can be used to manufacture porous electrodes for lithium-ion batteries – but because of the nature of the manufacturing process, the design of these 3D printed electrodes is limited to just a few possible architectures...

Scientists have synthesized a new cathode material from iron fluoride that surpasses the capacity limits of traditional lithium-ion batteries. As the demand for smartphones, electric vehicles, and renewable energy continues to rise, scientists are searching for ways to improve lithium-ion batteries – the most common type of battery found in home electronics and a promising solution for grid-scale energy storage. Increasing the energy density of lithium-ion batteries could facilitate the development of advanced technologies with long-lasting batteries, as well as the widespread use of wind and solar energy...
