隨著全球環保意識的提升，儲能領域的發展也越來越興盛，而其中鋰離子電池的需求越來越大，特別在車用領域，市場傾向於能量密度高、壽命長、快充、安全、便宜的電池，在追求能量密度的同時，也就是在一定的體積或重量下增加電量，相對的安全性風險會越來越高，甚至會危害到人的財產生命安全，所以安全性為電池領域中不可忽視的一環。

本研究以鋰離子電池安全性為主題，先探討近期電池的發展狀況，使用電池的衍生問題，再探討電池的工作原理、熱失控發生機制，並介紹美國、歐洲、中國對於安全性的測試標準，找出適合的關鍵字進行檢索，並挑選適當的分類號，藉以分析其專利申請趨勢，以及介紹相關專利，以提供產業對於安全性開發之參考。

With the increasing global environmental awareness, the development of energy storage has been flourishing, and the demand for lithium-ion batteries has been growing, particularly in the automotive sector. The market tends to favor batteries with high energy density, long lifespan, fast charging, safety, and affordability. However, while pursuing higher energy density, which means increasing the energy capacity within a certain volume or weight, the safety risks also increase. This could potentially endanger people's property and lives, making safety an indispensable aspect in the field of batteries.

This study focuses on the safety of lithium-ion batteries. It starts by examining the recent development of batteries and the associated issues in their usage. The working principle and the mechanism of thermal runaway in batteries are explored. Additionally, safety testing standards in the United States, Europe, and China are introduced. Suitable keywords are identified for retrieval, and appropriate classification codes are selected to analyze the trends in patent applications related to battery safety. Furthermore, relevant patents are presented to provide the industry with references for the development of safety measures.
