Publication number: 20220388846Abstract: Particulate material comprising rough mesoporous hollow nanoparticles. The rough mesoporous hollow nanoparticles may comprise a mesoporous shell, the external surface of which has projections thereon, the projections having smaller sizes than the particle size. The particulate material may be used to deliver active agents, such as insecticides and pesticides. The active agents can enter into the hollow core of the particles and be protected from degradation by sunlight. The rough surface of the particles retains the particles on plant leaves or animal hair. Methods for forming the particles are also described. Carbon particles and methods for forming carbon particles are also described.Type: ApplicationFiled: April 27, 2022Publication date: December 8, 2022Inventors: Chengzhong YU, Meihua YU, Hongwei ZHANG, Yusilawati Ahmad NOR, Hao SONG, Neena MITTER

Patent number: 11411281Abstract: A multi-layer composite functional separator for lithium ion battery includes four layers. Layer A is a base separator. Layer B is a porous structural layer composed of insulating inorganic compounds or high temperature resistant polymers. Layer C is a porous layer composed of polymer microspheres with temperature-induced expansion characteristics. Layer D is a thermoplastic resin with a melting point of 80-110° C. and a crystallinity of <50%. Layer B, Layer C and Layer D are sequentially attached on either or both sides of Layer A. Compared with the existing lithium-ion battery separator, the multi-Layer Composite functional separator has excellent heat resistance. The thermal shrinkage rate is less than 1% when heated for less than one hour at 200° C. Inclusion of organic polymer microspheres produces thermal closure of the batteries, which improves the safety of the batteries.Type: GrantFiled: November 14, 2016Date of Patent: August 9, 2022Assignee: Shanghai Dinho New Material Technology Co., Ltd.Inventors: Jianhua Li, Suzhen Cheng, Zhengqiang Wang, Meihua Yu, Qingling Zhi, Xin Zhang, Shaojun Yan
