聚酰亚胺纳米纤维锂电隔膜 先进科技打造一流产品

　　聚酰亚胺纳米纤维锂电隔膜技术进展/ Technologies Update of Polyimide Nanofibers LIB Separator

　　聚酰亚胺纳米纤维锂电隔膜技术进展

　　聚酰亚胺(PI)是综合性能最佳的聚合物之一。其耐高温达 400℃以上，长期使用温度范围200～300℃，绝缘性能好。

　　2010年，杜邦公司(DuPont)基于纺丝工艺得到直径200-1000纳米纤维，开发出Energain聚酰亚胺电池隔膜。杜邦宣称该隔膜可提升15%-30%的电池功率，可延长20%的电池的寿命，并改善电池在高温工作状态下的稳定性。

　　深圳惠程是我国聚酰亚胺电池隔膜生产和应用领域的领先企业，其间接控股子公司江西先材纳米纤维科技有限公司聚酰亚胺纳米纤维电池隔膜项目于2011年获得国家战略性新兴产业投资1,773 万元。

　　深圳惠程公司的300平方米/天PI纳米纤维锂电隔膜中试生产线已于2011年底完成安装和试车，现已投入运行，而后进入3000平方米/天的产业化生产线建设。预计2012下半年将PI纳米纤维锂电隔膜推向市场。

　　2011年3月，深圳惠程公告，江西先材纳米纤维科技有限公司与南昌高新技术产业开发区签订《投资协议书》，规划建设年产2亿平方米聚酰亚胺纳米纤维电池隔膜产品生产基地。项目用地约200亩，总投资约6亿元人民币，预计2014年投产。

　　由亚化咨询主办2012中国锂电隔膜研讨会将于6月18-19日在深圳召开，来自深圳惠程公司的专家将出席，并做题为“锂电用聚酰亚胺(PI)纳米纤维隔膜技术进展情况”的大会报告。

　　Technologies Update of Polyimide Nanofibers LIB Separator

　　Polyimide (PI) is one of the best performance polymers. It can be used in high temperature (above 400 ℃), and long-term used in temperature range of 200 ~ 300 ℃. It also has the high insulation property.

　　In 2010, DuPont developed the Energain™ separator, which is made from a proprietary, polyimide-based polymer produced using a spinning process that resulting in continuous filaments with diameters between 200 and 1,000 nanometers. ACCORDing to Dupont, the Energain™ separator can increase power from 15 percent to 30 percent, increase battery life by up to 20% and improve safety by providing stability at high temperatures.

　　Shenzhen Hifuture Company is the leading player in PI battery separator production and applications in China. In 2011, its subsidiary – Jiangxi Xiancai Nanofibers Technology Company – got the RMB 17.73 million subsidies from the government for the nanofibers polyimide battery separator project as it is a national strategic emerging industrial project.

　　By the end of 2011, Shenzhen Hifuture’s 300 m2/d PI nanofibers LIB separator pilot was started up and commissioned, and then started the construction of 3000 m2/d commercial production line. It is expected to start up and produce on-spec PI nanofibers separator in H2 2012.

　　In March 2011, Shenzhen Hifuture announced that its subsidiary - Jiangxi Xiancai Nanofibers Technology company had signed an agreement with the local Government of Nanchang, Jiangxi Province, plans to build an annual output of 200 million square meters of polyimide nanofiber battery separator production base. Approximately 200 acres of land will be used for the project, and the total investment is around RMB 600 million, the project is expected to be started up in 2014.

　　On Jun. 18-19, ASIACHEM will organize the “2012 China LIB Separator Conference” in Shenzhen. On the upcoming event, the expert from Shenzhen Hifuture Company will deliver a presentation on “Technologies Update of Polyimide Nanofibers LIB Separator”.
