| Abstract: | 近年來，全球暖化問題日益嚴重，許多國家紛紛確立了淨零碳排的目標，並頒布了禁止燃油汽車銷售的法規，直接推動電動車產業在未來的發展。然而，電動車的高昂價格和續航里程不足等問題仍然存在，影響了其全面普及。因此，本研究從專利分析的角度出發，並以在未來有望成為發展重點的動力電池領域為例，利用技術進步率的估計推敲在未來具備發展潛力的技術領域，建構專利引用網絡了解其發展脈絡，並選取美國和中國專利局資料，針對二國在動力電池產業鏈的上中下游技術發展進行研究，以了解產業的現況及發展趨勢。本研究利用1990年至2022年間的專利資料，研究結果顯示，中國的動力電池研究發展主要由企業和學術機構驅動。在發展趨勢方面，中國在上游領域致力於開發多元化的複合材料。在中游領域，中國專注於優化生產製程，以降低電池的成本和提高效能。在下游領域，則專注於改善車體的儲能能力，以提供更好的使用體驗。相較之下，美國的動力電池發展主要受到日本和韓國企業的驅動。在上游領域，美國企業致力於固態電池的研究和開發，以追求更高效能和更可靠的電池技術。在中游領域，通過改變電池模組的結構來提升性能和可靠性。在下游領域，美國致力於發展智能化充電系統和充電基礎設施，以提供更便捷和智能化的充電體驗。
In response to the escalating global warming crisis, countries worldwide are prioritizing the transition to net-zero carbon emissions and phasing out fossil fuel vehicles. The electric vehicle (EV) industry is at the forefront of this transformation. However, challenges such as high costs and limited range hinder widespread EV adoption. This study examines the developments in the electric vehicle battery industry`s upstream, midstream, and downstream sectors in China and the United States using patent analysis. The research reveals that in China, enterprises and academic institutions drive the research and development of key battery technologies. China focuses on diversifying composite materials and exploring solid-state batteries in the upstream sector. In the midstream sector, efforts are directed towards optimizing production processes to reduce costs. Improving the energy storage capacity of vehicle bodies is a recent trend in the downstream sector. In the United States, the development of electric vehicle batteries is primarily driven by Japanese and South Korean companies. US firms concentrate on solid-state battery research in the upstream sector, while in the midstream sector, they enhance performance and reliability through battery module structure improvements. The US also prioritizes developing intelligent charging systems and infrastructure in the downstream sector. |
