Electric car engines with nanotechnology batteries may be the vehicles of the future, but what exactly are these batteries and how do they help electric cars? Batteries that are the product of nanotechnology have an increased power, and take much less time to recharge than traditional batteries do. Nanotechnology allows the surface of the electrode in the battery to be coated with nanoparticles. This method creates a larger surface area on the electrode, and this will allow an increased flow of current between the chemicals that are stored in the battery and the electrode. This means lighter batteries that are much easier for cars to carry, and also allows for more or larger batteries without increasing the weight compared to traditional batteries. This can make electric cars much more efficient because they will require less recharging time and go further between charges.

Batteries that use nanotechnology also last much longer when not in use, for an increased life. These batteries separate the liquids and electrodes when the battery is not being used, so that there is no low level discharge to shorten the life of the battery. One of the most well known nanotechnology produced batteries is the Lithium ion battery. This battery is very light in weight, and has increased the efficiency of electric cars significantly. These batteries also last around ten years, which is almost double the life of nickel metal hydride batteries.

Electric car engines that use nanotechnology batteries may end up being the engines of the future. Nanotechnology batteries offer many benefits over other battery types, including both efficiency and durability. Advances in nanotechnology may even further revolutionalize the way batteries are made and used. Global warming and concern over the environment and our effect on it has caused many people to examine their vehicle and transportation options more carefully, and try to choose options which have a more positive environmental impact. Electric cars that use nanotechnology batteries are a huge leap in this direction. Electric cars cause no pollution and emit no greenhouse gases, making them a much better alternative to gasoline and diesel vehicles. With electric cars, there is also no dependence on oil and other fossil fuels, or outrageous diesel and gas prices because of fossil fuel imports from foreign countries and worries about supply and demand.

Protecting the environment and our atmosphere means using green energy and fuel sources, and this is exactly what nanotechnology batteries used in electric cars provides. Nanotechnology has advanced to the point where electric cars are much more efficient and convenient than they used to be, and there is not a need to recharge frequently or be limited to a small distance. Electric cars are one option for a fossil fuel free future, and nanotechnology batteries make this option a very real possibility. The future of transportation in America, and across the globe, may include electrical recharge stations instead of gas stations, and an energy grid may be developed to allow electric cars to be charged during hours with low demand instead of peak hours where electricity is in very high demand. The end of oil based fuels is near, and alternative energy methods must be perfected before this happens. Until nanotechnology batteries were developed, electric cars did not show much promise as a major alternative. Since nanotechnology has been used together with batteries, however, the electric cars of the future may become very efficient, and be a major transportation source for many people including Americans.
