Scientists develop fast recharging material for lithium-ion batteries

A group of South Korean scientists has developed a new material for a secondary or rechargeable battery that can be fully recharged in just a matter of minutes, the science ministry said Monday. The development of such a battery could significantly raise the popularity of electric vehicles whose lithium-ion batteries currently take hours to recharge, according to the Ministry of Education, Science and Technology.

Conventional batteries use only powdered nanoparticle materials to form a dense, multi-layered structure that can store and give off energy. The new battery, on the other hand, uses the same type of nanoparticle materials that are first resolved in a solution that contains graphite, which later is carbonized to form a dense network of conductors all throughout the electrodes of the battery, the ministry said.

As a result, all energy-holding particles of the new battery start recharging simultaneously while the same particles in conventional batteries begin recharging in order from the outermost particles to the innermost.
