Increased Capacity

As seen in the graph, the battery containing GS Ionic Liquid as an electrolyte significantly outperformed its conventional counterpart.

At a constant discharge current of 160mA (0.2C x 800mAh), the original Li-Ion battery only yielded 800mAh of electrical capacity vs. over 1700mAh for the GS Ionic Liquid-containing battery. The GS Ionic Liquid batteries also sustain higher voltages for longer, as evidenced by the relative ‘flatness’ of the curve(s), meaning more use out of a single charge for a given application.

These tests were conducted using a typical off-the-shelf cellphone Li-Ion battery, modified by the addition of GS’s Ionic Liquid to the existing electrolyte or its entire replacement, as shown by the blue and red lines respectively.

Since the ‘wetting’ of the separator and complete removal of electrolyte from the interior of a Li-Ion battery are difficult to reverse post assembly, GS expects to see even greater improvements by incorporation of its Ionic Liquid during a de novo battery build.

GS Ionic Liquid isn’t just for small applications such as cellphone batteries either – test results indicate performance increases just as pronounced for larger Li-Ion batteries, such as those anticipated for use in automotive applications.
