In the light of world shifting to green economy, the responsibility of replacing the petrol and diesel sources with some better and greener sources of fuel is really a big deal and that to, for a densely populated country like INDIA it seems like easier said than done.
For entrepreneurs and researchers, it is important to understand the mindset and the problems of mass, and then to work on the problems and build up a problem-solving product. Let’s see the following story to understand some basic but worthy problems of people-
One fine morning Ravi wakes up an and gets an urgent call to immediately attend an important meeting in his office. Ravi has both an electric car and a petrol car, but the problem is that neither the electric car is charged nor the petrol car is filled with fuel .In such instances instead of charging the electric car for around average of 2 hrs. , he would definitely fill the normal car with fuel which would hardly take seconds instead of waiting for the battery to be charged.
Similarly, if we keep a fully charged electric car idle for like 3 to 4 weeks, we will see that there will be a significant amount of loss of charge, but for a full tanked petrol car there will be less loss (due to evaporation and other factors) compared to an electric car.
People cannot go with an electric car for long distance. Always there will be a range anxiety as well as due to lack of charging infrastructure a normal middleclass man will not prefer an electric car instead, he would definitely go for a petrol car after all everyone wants to save time. In short Limited driving range, high costs, battery issues, and a spotty charging infrastructure are the main challenges for battery electric vehicles (BEVs). Although this is eco-friendly but its challenges hide its main importance and need in this greatly polluting world. Over the past few years, researchers from all over the world are trying to build a fast charging long battery life (more cycles). Who knows may be in the near future we can see great battery technologies that could charge up in seconds with high energy and power density i.e. capable enough to hold charge for long time and as well as long lifespan.
The line which we draw on our paper with pen or pencil is itself has certain thickness but still it could not be termed as 2D, but definitely this particular thing (GRAPHENE) IS 2D. Yes, Graphene has only single layer of atoms of carbons linked with each other in hexagonal structures. Sometimes it is called as single layer of graphite.
Over the past few years, we have seen a huge and rapid development of battery technologies especially lithium ion batteries and its variations with different other substances. We have seen great companies like TESLA MOTORS, SAMSUNG to provide batteries with fast charging and even new innovative Bluetooth charging facilities. But the problem remained unsolved i.e. no such technologies couldn’t be created that can charge up in seconds.
