The invention relates to an electrode for a lithium battery that contains LiFePO4 as electrochemically active material and a binder consisting of polyacrylic acid. This may be accomplished by having the network controller obtain and maintain a list of services provided by all of the associated devices in the network. 1\u02dc30 kN\xb7m2 when the width of close contact area between the slave medium and master carrier is defined as 1 m, and wherein the practical thickness of the holder is not less than 3 mm and not more than 15 mm. Preferably, these staples have Moment of Inertia Ratios on the order of between about 1. The polycentric hinge has a slotted central plate with star gears engaging a back portion and multiple movable blocks mounted in screw holes on a front edge of the slotted plate supporting an elastic band having a fulcrum point on the polycentric hinge at a lower and upper end.
