Abstract: A battery provided with the following elements: a battery case; a metal terminal fixed to the battery case; a hole created in the metal terminal, having an opening part outside of the battery case; a member fitted into the hole, composed of a material whose mechanical strength is higher than the metal terminal, wherein the member comprises a projecting portion which protrudes from the hole; and a male screw part created in the projecting portion.

Abstract: An insulating sleeve 6 made of ceramic hermetically fixed into an opening in a terminal supporting plate 7 in a battery sheath made of metal, a positive terminal 4 made of an aluminum alloy or negative terminal 5 made of a copper alloy is inserted in the insulating sleeve, and a metallic ring is fitted over the positive terminal 4 or negative terminal 5. The inner edge of the metallic ring 11 and the positive terminal 4 or negative terminal 5 are hermetically fixed to each other by an aluminum-based brazing metal 8 or copper-based brazing metal 9, and the outer edge of the metallic ring 11 and the insulating sleeve 6 are hermetically fixed to each other by an aluminum-based brazing metal 8 or copper-based brazing metal 9.

Abstract: An artificial satellite is equipped with solar batteries and a non-aqueous electrolyte battery module for artificial satellite (i.e., a lithium battery). The non-aqueous electrolyte battery module is provided with a non-aqueous electrolyte battery, a temperature sensor, a charged state measurement sensor, and a computer for receiving signals output from the sensors. The managed temperature of the non-aqueous electrolyte battery in a solstice season is set so as to become equal to or lower than the managed temperature of the battery when the satellite is in the solstice season. The computer controls a temperature controller, thereby maintain the managed temperature of the battery within a given temperature range. The charged state of the lithium battery is controlled by means of turning on or off a charging switch under the control of computer. When the satellite is in the eclipse season, the managed charged state of the non-electrolyte battery is controlled so as to be a value of 50% or more.
