Current Limitations of Traditional Satellite Power Systems

Batterie Degradation and Capacity Fade

Traditional lithium- jon batterie - thee standard for most satellites today - suffer frem gradual capacity fade due to te formation of solid- elektrolite interfaxe (SEI) layers and lithium plating during charge-dicharge cycles.
