DAEJEON, Oct. 8 (Korea Bizwire) — Industry-academia research collaboration will be pursued to develop an eco-friendly battery that is free from carbon emissions.
The Korea Institute of Energy Research (KIER) said Thursday that it will invest 11.4 billion won (US$9.54 million) over the next five years to develop a solvent-free lithium ion battery dry process in collaboration with three research institutions, two companies and two universities.
An electric car battery, in general, generates 42 kilograms of carbon dioxide per kilowatt-hour to dry the solvent during the wet electrode manufacturing process.
Due to the layer separation phenomenon that occurs between solvent and element during the wet manufacturing process, it’s impossible to extend the thickness of electrode coatings up to a certain level, thereby limiting energy density.
The joint research team plans to develop demonstration-level devices and equipment based on the concept of dry processing, which does not use solvent in the process of wet electrode manufacturing for lithium ion batteries.
By creating a solvent-free dough-type dry compound that has zero carbon emission, the research team plans to develop various electrode elements and equipment to realize a lithium ion battery that has 1.6 times higher energy density than existing batteries.
