Lithium-ion
Lithium-ion is a type of rechargeable battery commonly used in space and astronautical engineering due to its high energy density, low self-discharge rate, and long cycle life. Lithium-ion batteries are made up of a cathode, an anode, and an electrolyte, with lithium ions moving between the two electrodes during charging and discharging. The cathode is typically made of a lithium metal oxide, while the anode is made of graphite or other carbon-based materials. The electrolyte is a lithium salt in an organic solvent. Lithium-ion batteries are used in a variety of space applications, including satellites, rovers, and spacecraft, due to their ability to provide high energy density in a small and lightweight package. However, they can be sensitive to temperature and require careful management to prevent overheating or overcharging.
