Abstract
携帯電話は, テレビ電話機能の搭載, 高速通信および内臓アプリケーションの利用増などにより消費電力が増えている.その消費電力を賄っているリチウムイオン電池には容量アップなどの大きな期待があるが, 課題も多くある.本稿では, 携帯電話用のリチウムイオン電池の動向, 同電池の安全性やメンテナンス技術を示す.
Mobile phone now incorporates a video phone function and the introduction of unlimited-packet-use services are promoting increased use of applications, and these consume more power. While the lithium-ion batteries play the current power source for mobile phone, there are some subjects. In this paper, we present battery trend, safety and capacity deterioration for lithium-ion battery in mobile phone.
