Car Battery Modernized
Many people are not aware of the fact that not only is Edison credited with having invented the telegraph and light bulb in the early 20th century, but he also designed an electric car battery. The very same technology has returned as a 21st century power charging source.
The most modern version of the Edison battery may be charged fully in approximately just 2 minutes. The energy load can be transmitted in under 30 seconds which is about 1,000 times more quickly as compared to the original. However, existing batteries can hold only enough power for one flashlight.
Stanford University scientists hope to enhance Edison's battery so that it can be used in more electric vehicles. While the Edison battery is quite durable, there are some drawbacks. It can take hours to charge a typical battery and its discharge rate is very slow.
Nanotechnology is responsible for the boosted charging speed for Edison's battery. This was accomplished when researchers were able to bond battery metal particles with nonomaterial carbons, graphene and multi-walled nanotube carbons. This can effect an increase in electrical conductivity.
The first nickel iron battery was released by Edison in the 1900s as a less expensive alternative to traditional lead acid batteries with better reliability and longer life. The battery was first used in electric cars in around 1920. However, it did became a useful backup source in the mining and railroad industries up until around the mid-20th century.
The nickel iron batteries of today usually work by storing electricity that is derived from wind turbines and solar panels. The newest Stanford car battery has an increased charging speed. However, scientists want to enhance its ability to hold a charge over a longer time period, since the current decay is equivalent to what is experienced with lithium ion batteries.
Success could easily occur for the new car battery after the electric and hybrid cars are more fully embraced. It is surmised that the U.S. military could find these batteries useful for instances where soldiers require a more efficient and effective power source for their equipment.
