锂离子电池在储能中的应用及安全问题分析

2050年可再生能源电力占我国电力消费的比例将超过70％,而储能系统应用的深度和广度对新能源的进一步发展起着决定性的作用.虽然抽水蓄能的能量占比最大,受其局限性太强的限制,实际在储能中最具有关键地位的是电化学储能里的锂离子电池储能.现在锂离子电池研究最大的瓶颈就是其安全可靠性.一方面是提高电池能量密度,另一方面是保障安...

Application of lithium ion battery in energy storage system and analysis of its safety problems

The percentage of renewable energy in electricity consumption will exceed 70%in 2050,and the depth and width of the application of energy storage system will decide the continuing development of new energy.Although the percentage of the pumped hydroelectric storage is the highest,due to its strong limitation,the energy storage of lithium ion battery plays a pivotal role in practice.The research bottleneck of the lithium ion battery is its safety.The improvement of energy density is opposite to the safety guarantee.The percentage of lithium ion battery in energy storage was discussed.The current safety risk,the occurred accidents and the issued standards were analyzed.Several prevention and promotion safety strategies of lithium ion battery were provided.It’s concluded that there is still a long journey to overcome the safety problems and multiparty must attend in the everlasting battle.
