By using such a current collector, separation of the active material from the current collector can be inhibited when using an active material that has a high capacity but undergoes a large expansion at the time of lithium ion absorption.

Abstract: The present invention relates to a solid electrolyte including Li, O, P and a transition metal element. In the solid electrolyte, because the transition metal element T is reduced prior to phosphorus atoms, it is possible to prevent the valence of phosphorus atoms from decreasing. Thereby, the decomposition of the solid electrolyte resulting from the decrease of valence of phosphorus atoms is prevented, and therefore high ion conductivity is retained even in a wet atmosphere.

Abstract: In accordance with a handoff method, when a handoff of mobile terminal equipment from a previous foreign agent to a new foreign agent is detected, the mobile terminal equipment is doubly registered with either a home agent or a gateway foreign agent so that the mobile terminal equipment is associated with both the previous foreign agent and the new foreign agent. During the handoff, either the home agent or the gateway foreign agent determines whether or not an IP packet destined for the mobile terminal equipment is of real-time traffic, and then bicasts the IP packet to both the previous foreign agent and the new foreign agent if the IP packet is of real-time traffic, and buffers the IP packet otherwise. When the handoff is completed, the regional registration with either the home agent or the gateway foreign agent is updated so that the mobile terminal equipment is associated only with the new foreign agent.
