Battery Chargning Research finds New Formula for Fast Charging Batteries

For those unfamiliar with battery charging, ANY battery change be charged quickly, not as fast as SuperCapacitors, but definitely in minutes. However, two major problems make this unwise.

1. There is a potential for the battery to overheat and possibly explode.
2. If battery does not explode, there is a good change the battery will be damage in a way that shortens the battery life.

Regardless, there are lots of tricks, including making changes in the battery formula. This article from koreabizwire.com outlines the results from the research.

A joint research team from Pohang University of Science and Technology (POSTECH) and Sungkyunkwan University announced Monday that they had developed EV battery technology that enables faster and more durable charging.

Thus far, decreasing the size of particles of electrode materials was the primary method to speed up charge and discharge from secondary cells or EV batteries.

The downside, however, was that this method reduced the density of energy in the cell.

The research team came up with a solution that enables quick charge and discharge without loss of energy density by creating an intermediate phase during the phase variation of charge and discharge, without having to reduce the size of electrode particles.
