基于专利指标的新兴电化学储能技术未来产业影响力比较

Comparison of Industrial Influence of Emerging Electrochemical Energy Storage Technology Based on Patent Indexes

摘要:

为探索更加完善的新兴电化学储能技术未来产业影响力比较体系，引入技术价值度、国际市场布局、合作研发强度、产学研合作密度、专利申请量等指标，依据改进粗糙集属性重要度权重计算方法，对锌空气电池、钠离子电池、铝空气电池与钠硫电池进行连续6年的未来产业影响力综合比较。研究结果表明：锌空气电池未来产业影响力最接近于钠硫电池，但仍差距很大，需加强技术合作；钠离子电池产业影响力近年呈“井喷式”增长态势，未来产业影响力仅次于锌空气电池，在保持产学研合作力度的同时需注重成果转化；铝空气电池未来产业影响力最小，需加大研发投入以取得技术进步。

Abstract:

In order to explore a more complete comparative system on future industrial influence of emerging electrochemical storage, the paper introduces the following indicators: technical value degree, layout in international market, strength of R & D cooperation, cooperation density of industry, university and research, the number of patent applications. Based on the improved rough set attribute importance weight method, the comprehensive comparison of future industrial influence of zinc air battery, sodium ion battery, aluminum air battery and reference technology: sodium sulfur battery for six consecutive years was carried out. The results show that the future industrial influence of zinc-air battery is closest to that of sodium-sulfur battery, but there is still a big gap between the two. It is necessary to strengthen technical cooperation. In recent years, sodium ion battery future industrial influence showed “blowout” growth trend, second only to zinc-air batteries. It needs to focus on the transformation of results while keeping the current cooperation density of industry, university and research；aluminum air battery nfuture industrial influence is still too early. Aluminum air batteries have the least future industrial influence, need to increase R & D investment, the first to make technological progress.
