Changing the new EV battery to give them more sustainability and more extended range

Ev batteries are a huge milestone in beating the use of engines that run on fossil fuels. It has changed to produce a battery that is more sustainable and with even better environmental ratings. These batteries had some components that were not environmentally friendly on their ageing.

A team of researchers from the Korea Institute of Science and Technology embarked on a task that would see a complete transformation on these batteries. They sought to replace the graphite with highly sustainable material and a biobased material in the new EV supply chain. Developing a sustainable and purely carbon-free EV engine has been a goal of the United States for both national defense and economic reasons. 

The research findings of KIST might be a breakthrough for solving the problem of carbon emission that comes towards their being overly heat. This research program is after getting a substitute for graphite on the lithium-ion batteries anodes. As a biobased program, their goal will be ensuring that they have beat the problems that come with the mining of graphite. It will be a great relief from the importation of graphite which stopped in 1990 in the USA. This idea, if it comes to be, will solve multiple problems associated with environmental pollution. 

Away from the issue of sustainability, there is the need to eliminate the limitations that come with graphite on these EV batteries. Solutions like silicon have been dispelled on the grounds that they behave unevenly, making them unsuitable for these batteries. Solving the issue as per KIST implies the combination of silicon with other materials.

Through a simple thermal process commonly applied in frying food, they dissolved corn starch in water, mixed in silicon and oil, and then heated it up. There was the formation of micro sized carbon spheres around the silicon and a layer of graphite carbon. These spheres come in to prevent the silicon from expanding when it comes to the charging cycles. Additionally, they were a great remedy to efficiency in conductivity.

From the research by the KIST team, it was observed that an increase in capacity to four times over that of graphite anodes was the way out of this current problem. Charging capacity and time increased with the batteries having the ability to charge to over 80% within five minutes. Such discoveries have revolutionized the production of EV batteries towards the goal of the complete elimination of carbon footprint.
