Features
The feature of the lithium ion Cell.
- High energy density
Less than 1/2 which is Ni-Cd battery compared with the mass. - No memory effect
No reconditioning is required on-orbit. - Small self-discharge
Reduce the launch operation for back-up charge of batteries.
Applications
Supply of electric power to a satellite/probe when solar power is not available (eclipse period).
