“…Previously, in Korea, patent was conducted to analyze patent trends on waste battery recycling. Keywords were battery, electronic cell, patent, recycling, and 2,490 cases were selected from 1971 to 2000 for H01M-006/52 and H01M-010/54 among IPC classifications, and 871 of them were analyzed through filtering [16].…”

This study provides a comprehensive analysis of global patent trends in battery recycling, focusing on secondary batteries and related technologies across Korea, China, and the United States. The data, collected from various patent databases, was quantitatively analyzed to identify technology trends and direct future development. The analysis reveals distinct emphases on technologies such as lithium-ion and waste battery recycling, highlighting notable differences in patent activities among key companies and countries. China's large number of patents in battery manufacturing processes contrasts with the USA's focus on electrochemical cell construction and storage systems, while Korea shows significant activity in waste battery technology. The study underscores the competitive landscape and innovation efforts in the battery recycling sector, providing insights into the technological focuses and priorities of each country. It also identifies key challenges, such as the need for consistent innovation and broader geographic coverage in Korea, enhancing patent influence and international presence in China, and ensuring high patent quality and fostering innovation in lagging sectors in the United States. Addressing these challenges through enhanced collaboration, increased R&D investments, and supportive policies is crucial for strengthening the global position and driving further innovation in the battery recycling sector.

Mobile phone has become one of the essential items in our daily life. In Korea, it is estimated that more than 20 million cell phones are discarded each year due to advancement in technology, thus creating disposal and environmental pollution. In order to conserve the resources, their proper recycling is essential as it contains both valuable and toxic metals. The economics of the recycling will depend on the amount and value of the metals. Therefore, it is necessary to determine the composition of the metals present in the different cell phones. In the present study, a report is presented on the variation of metal content per year of waste mobile phones. A review has been made for the mobile phones manufactured during the period 2000-2009 and metal content of the printed circuit boards (PCBs) by analyzing their metals. An example of the precious metal palladium and of the heavy metal lead shows the decreasing trend.
