                  关于获得专利证书的公告

      本公司及董事会全体成员保证信息披露内容的真实、准确、完整,没有虚假记载、
  误导性陈述或重大遗漏。

    广州鹏辉能源科技股份有限公司(以下简称“公司”)及子公司近日收到国家知识 产权局颁发的发明专利、实用新型及外观设计专利证书,具体情况如下:

    一、发明专利

                                                                    本发明提供了一种锂
                                                                电池隔膜及其制备方法和
                                                                应用,涉及锂电池的技术领
                                                                域。一种锂电池隔膜,包括
                                                                基膜以及基膜上覆盖的有
                                                                机弹性材料涂层;隔膜在横
                                                                向和纵向的拉伸强度均为
                                                                200-300MPa,断裂伸长率均
              锂电池                            广州鹏        为80%-150%,抗穿刺强度
      第      隔膜及 谭玉明 ZL 2022 1 2021年  辉能源 2023年 在950GF以上。该隔膜中有

              应用                              公司          段共聚物和热塑性聚氨酯
                                                                弹性体橡胶中的至少一种。
                                                                该锂电池隔膜具有较高的
                                                                机械强度,改善了隔膜在机
                                                                械方向(MD和TD)的拉伸强
                                                                度和抗穿刺强度。有机弹性
                                                                材料涂层耐电解液腐蚀,当
                                                                外力冲击电池时,涂层将保
                                                                证正负极材料不短路,提高
                                                                了锂离子电池安全性。

                                                                    本发明的一种极片制

                      王文艳                    公司          成卷芯;步骤三、对卷芯通
                                                                过压力设备进行热压或冷
                                                                压。由于压花区的存在使得

                                                                极片的表观厚度增厚,卷绕
                                                                完成后,再对卷芯进行热
                                                                压,压花区被压平,使得外
                                                                圈周长变长,恰好用来抵消
                                                                由于拉力释放缩小的周长,
                                                                避免了内圈的卷芯受力变
                                                                形。
