Non-woven Diaphragm Completes Adjustment In New Energy Battery

2019-02-09 22:01:51
In the future, it is intended to achieve the goal: the ceramic non-woven(China Spun bonded Non Woven Manufacturer) diaphragm will be tested and adjusted in the new energy vehicle lithium battery production line, reaching or close to the technical performance indicators of imported products. Complete the preparation of the technical production line technology package, investigate the market technology progress of the products, and promote the industrialization development.

In April 2017, China Haicheng responded to investors' questions and said that the company's lithium-ion diaphragm-based technology research and development is still in the laboratory research and development stage.

In the 2016 annual report, Jinli Co., Ltd. showed that new products such as high-heat-resistant composite non-woven fabric separators (heat-resistant temperature of 300 °C or higher) developed by the company are currently in the customer trial stage and will be put into production in 2017.

At the end of 2016, Ningbo Aitemic Lithium Technology Co., Ltd. stated that its high-performance nanofiber separator Sahara Aspen can be used for power lithium. The fiber diameter is 50 nm, the membrane aperture is 300-400 nm, and the membrane thickness is 15-30 μm, and the price is about 10 yuan/m2. At present, the diaphragm test equipment with an annual output of 2 million square meters has been installed, and it is undergoing pilot test and process commissioning, and then transferred to small-scale production.

In October 2015, Wuhan Textile University applied for a patent for the preparation of a polyphenylene(Polypropylene Spun-bonded Non Woven Wholesale) sulfide ceramic composite separator for lithium ion batteries. In the invention, a ceramic slurry prepared by using inorganic nanoparticles and a binder is applied to a surface of a polyphenylene sulfide-based film having a high melting point to prepare a polyphenylene sulfide ceramic composite separator. The thermal stability of the separator is significantly improved compared to the polyolefin ceramic composite separator.

In April 2017, the Textile College of Donghua University made progress in the research of fiber-based lithium-ion battery separators. The PVDF-HFP polymer is combined with the inorganic high temperature resistant staple fiber by wet-laid to prepare a separator based on the inorganic fiber nonwoven skeleton. After the separator is assembled into the battery, its electrochemical performance is significantly improved at both normal temperature and high temperature.

In the future, many facts will be continuously verified in experiments, such as the beginning of the use of non-woven(Spun bonded Non Woven Vendor) membranes made of glass fiber, can also be used for lithium-ion batteries, as well as PP / PE microporous membranes, the original pore size and porosity Large, but the time of lithium-ion battery is mainly used for cameras and mobile phones. The thickness of the diaphragm is thin and has a closed-cell function, which leads to the development of microporous membranes.
