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).
