首先刘彦龙秘书长介绍了“电池隔膜分会”的成立背景和意义。隔膜是锂电四大关键材料之一,也是国产化起步比较晚的材料,但最近几年,国内隔膜产业发展比较迅速。从市场份额看,国内隔膜产品已经占据隔膜市场90%以上;从客户结构来说,国内隔膜产品除了不断满足中国电池企业的需求外,很多高端产品大批量出口LG、松下等国外主流电池企业。近几年,我国隔膜业发展有目共睹。自2015年以来,我国新能源汽车边锋游戏产业发展带动隔膜产业快速发展,大量隔膜产线开始建设,技术提升较快;2018年,我国隔膜业产能出现结构性过剩,整个行业出现分化趋势。同时,隔膜价格也跟随行业发展出现不同程度的涨跌起落。


据中国化学与物理电源行业协会统计,2018年,国内隔膜产量约为20亿平方米,相比2017年增长了40%左右。其中湿法隔膜占主导地位,约为13亿平米,同比上涨65%,这主要还是得益于国内动力电池业的发展,以及中高端数码产品市场的增加。此外,由于湿法隔膜价格下降,与干法隔膜价格差距逐渐缩小,对部分干法隔膜形成替代,也奠定了目前湿法隔膜边锋游戏的主导地位。此外,国内动力电池业市场集中度的快速提升也带动隔膜业集中度不断提升,2018年前5名的隔膜企业占全部市场份额的55%,比2017年有所提高。刘彦龙表示,2019年以来,一线隔膜企业进一步提高技术水平、控制成本,三四线企业经营压力逐渐增大,一部分小规模企业可能关闭或倒闭。
