      Yes I am. I am working on improving/ developing energy storage devices to meet the energy demands in the future. In the future, we will have to depend a lot on energy storage devices such as batteries. Because we need to store the energy we produce (from solar power, wind power, hydro power etc.) in a device (such as a battery) until we need to use that energy (may be to drive your car, to light your home etc). For this, the device in which we store the energy (lets say it is a battery) should be able to store a large amount of energy and also should be able to release that energy very quickly when we want to use it. For eg. If one battery can store enough energy for you to drive your car for 100 miles, then you need to carry only one battery to drive 100 miles. But if it stores enough energy only to drive 1 mile, then you have to carry 100 batteries in your car! Also, when you need to start your car, you need to use some amount of energy stored in this battery in a few seconds. But if your battery takes a few minutes to release that energy, then you are in a trouble.
      So I am involved in developing devices, which can store large amount of energy and release that energy is a few seconds.
