With the advancement of battery technology, we believe batteries will soon be part of hybrid electric-hydrogen fuel cell powered vehicles. The purpose is to manufacture a safer lithium-ion battery compared to the current nickel-metal hydride batteries.

With lithium ion battery not only it’s a low cost option, we obtain 4 times the energy density of lead-acid batteries and two or three times the energy density if nickel-cadmium and nickel-metal hydride batteries.

A group of scientists have been involved in different programs, each researching different aspects of making hybrid electric-hydrogen vehicles a reality but the main one is focused on the areas of battery abuse tolerance and accelerated lifetime prediction, with abuse tolerance receiving most of the focus.


Their main objective is to develop a battery that has a better feature, which won’t cause any danger even if damaged; they need to understand better what causes the failure of batteries.

To comprehend the mechanism of the life cycle of the batteries is the technical goal especially the poor tolerance. Understanding the chemical response to abuse can point the way to better battery materials.

It comes down to the conclusion, that to find a good solution for stable battery, the need to improve cell materials, additives, designs and good engineering matter the most.

Working on poor tolerance can help figure out the main mechanism that control battery cells, starting with the effects on the anode and cathode, additives and electrolytes breakdown.

There is one other point to focus on which is to develop a method to predict lithium-ion battery life by doing an accelerated life test experiment.

With those two approaches in the researches, one surnamed the empirical model which generates life prediction from accelerated degradation test data, while the other approach named mechanistic model relates life prediction to changes in battery materials. Those approaches provide an independent measure of battery life so there is no need to keep up the conventional ways which were dictated by battery manufacturers.

With these approaches, scientists believe there has been substantial progress in making batteries more tolerant to abusive conditions and that it won't be long before safer lithium ion batteries will be fully used in gasoline-electric hybrid vehicles.
