DAEJEON, July 5 (Korea Bizwire) — South Korean researchers have developed a safe and cost-effective technology for the production of semi-solid batteries using electron beams.
The Korea Atomic Energy Research Institute said Tuesday that its team of researchers had successfully developed a “one-pot” technology. This innovative method utilizes electron beams to mass-produce semi-solid batteries in a single process.
When a liquid is exposed to an electron beam, a form of radiation, it undergoes a transformation into a semi-solid state.
However, current processes have limitations in terms of output expansion, and the high installation costs of electron beam equipment hinder economic feasibility.
To overcome these challenges, the research team conducted an analysis of the effects of electron beams on the internal materials of the battery to determine the optimal radiation dosage.
Through their research, a one-pot process was developed. This process allows for mass production in a single step by layering pouch-type liquid electrolyte batteries and subjecting them to an optimal dosage of electron beams.
The research team highlighted that this newly-developed technology enables the production of up to seven semi-solid batteries in a single process, while maintaining performance levels comparable to existing liquid electrolyte batteries.
