  A battery can change chemical energy into electricity by putting certain chemicals in contact with each other in a specific way. Electrons, which are minor parts of an atoms will travel from one kind of chemical to another under the correct circumstances. At the point when electrons stream, this generates an electrical current that can power something. The function of a battery is to put the right chemicals in the right relationships, and then it puts a wall between them. When the two sides of a battery are linked by a wire or another conductor then the electrons starts to flow. Batteries come in numerous styles. We are perhaps most familiar with single-use alkaline batteries. NASA spacecraft generally use rechargeable nickel-hydride or nickel-cadmium batteries like those found in cellular phones or laptop computers. DS1 uses nickel-hydrogen batteries. Engineers think of batteries as a place to store electricity in a chemical form. Batteries tend to expend their charge very quickly. DS1 can last from half an hour to three hours running purely on battery power before the batteries need to be recharged from the solar panels. These batteries are revived a huge number of times over the life of the shuttle.
