Battery Chemistry
Battery chemistry refers to the chemical reactions and materials used in the construction of batteries. In the context of space and astronautical engineering, battery chemistry is crucial for the design and operation of spacecraft and satellites. The choice of battery chemistry affects the performance, weight, and lifespan of the battery, which in turn affects the overall mission. Lithium-ion batteries are commonly used in space applications due to their high energy density, low self-discharge rate, and long cycle life. Other battery chemistries used in space include nickel-cadmium, silver-zinc, and alkaline. The selection of battery chemistry depends on the specific requirements of the mission, such as power output, temperature range, and radiation tolerance.
