The video features an exclusive interview with Deepu, a research student who has invented an eco-friendly battery that is processed entirely with water. He explains that his research focuses on developing a solid-state electrolyte to overcome safety issues associated with traditional lithium-ion batteries. The new battery is entirely processed with water, avoiding harmful chemicals, and uses a non-halogenated lithium salt, which is less hazardous. The battery is also eco-friendly and can be manufactured at a low cost. Deepu also shares that he chose South Korea for his research because of the country’s advancements in his field and the strong funding support for research.
