- 摘要
- 目前穿戴式電子產品蓬勃發展如智慧手錶、智慧眼鏡、穿戴式醫療照護產品、運動和健康管理產品等都是現今科技產業最關注的焦點。應用於穿戴式裝置的電池要求很高，不僅要小、輕、薄，還必須擁有強大能量。而且這些穿戴式電子產品由於頻繁地與人體接觸，因此對人體的安全性也是非常重要的一環。然而傳統的鋰電池在微小化有一定的困難度，以及液態有機電解質本身對環境及人體都擁有毒性，長時間的使用易產生漏液現象，造成鋰電池燃燒或爆炸的現象發生，大大增加使用電池的不安全性。全固態薄膜鋰電池可說是次時代鋰電池的一個重要發展，改善了傳統鋰電池安全性不佳的缺點。主要優勢在 (1) 全部是由“固態”材料組成，包括正極，負極和電解質。(2) 運用電漿技術控制電池的總厚度只有數μm，更容易微小化及和半導體製程結合。(3) 單位能量密度遠大於傳統電池。(4) 高安全性，經由固態薄膜的層層堆疊組成，不會在短路時或長時間的使用後產生漏液現象，造成鋰電池燃燒或爆炸的現象。本研究所研發的全固態薄膜鋰電池(all-solid-state thin-film battery, TFB)元件(2 cm × 2 cm × 0.03 cm)，擁有放電電容量570 μAh (相當於單位體積放電電容量47.3 μAh μm-1 cm-2)，50圈的充放電下還保有83%的放電電容量，可以有效驅動一些穿戴式電子產品，如LED燈、LED手環、LED手錶以及LED聲控發光衣服等。

- 2013 is seen as the first year of wearable electronics technology. According to IMS Research report, wearable technology market are expected to grow to over $60 billion by 2016. The growth of wearable electronics is towards the development of lightweight, slightness and being close to people life. Batteries used in wearable electronics require not only high performance but also other characteristics such as shape, size, safety, thickness and flexibility. However, the size and design of conventional Li batteries are limited because of their liquid electrolytes which are lithium salts in an organic solvent. In addition, liquid electrolytes have safety and health issues as they use flammable and corrosive liquids. All-solid-state thin film lithium batteries are composed of solid materials and are assembled layer by layer. It is easy to make them thin. Solid-state electrolytes have high energy density and power density and are very stable. In this study, we applied radio-frequency magnetron sputtering to produce flexible an all-solid-state thin film lithium battery. Electrochemical characterization of this flexible battery revealed a discharge capacity of 570 μAh (or 47.3 μAh μm-1 cm-2) between 4.3V and 3V. The maximum capacity retention in excess of 83% was achieved after 50 charge-discharge cycles between 4.2V and 3V. It has been used successfully for some wearable electronics such as LED lights, LED bracelet, LED watches and voice-activated LED luminous clothes.
