How does COVID-19 Impact of Lithium ion Battery Industry On February 10th, lithium battery industry chain enterprises out of Hubei Province, including battery companies, battery materials companies, and battery equipment companies, which have reached local resumption standards have officially started. The impact of the COVID-19 on the consumer side is obvious. Consumers willingness to purchase cars was curbed in January, and in addition to the sharp decline in new energy vehicle subsidies in 2019, the production and sales of new energy vehicles in January fell sharply. As two of the top domestic new energy vehicle sales companies, BYD's January sales report shows that in January 2020, the company achieved 7,133 new energy vehicle sales, a year-on-year decline of 75.12%. In view of the impact of the epidemic on the new energy vehicle and lithium battery industry chain in 2020, nearly 50% (48%) of the survey data believes that the short-term impact will be affected, but the impact will not be large throughout the year; The impact of energy vehicles and consumption and supply chains will cause a significant decline in the industry, accounting for 33%. 17% of these have not yet been conclusive. AOTELEC Battery Equipment Company donated 120,000 CNY to Wuhan, mainly for car disinfection and environmental disinfection. We hope that through our donation, we can do a little for the frontline epidemic prevention work in Wuhan. Reported by Jason Li, AOTELEC Company 2020-02-12

Hydraulic Coin Cell Crimper Shipped to Binghamton University It is a great honor to cooperated with Dr.Jatin from Binghamton University again. Our story was began on April 2019, we read an article about the choice of lithium ion battery electrolyte, and we both shared our opinions on comments area, then we have chance to communicate on lithium ion battery research.  Seveal days later, i was asked to provide a bottle of lithium chips to him, yes, that is our first cooperation. Now we have second business, this coin cell crimping machine is necessary equipment for lab coin cell making which is available for working in glove box. It is suitable for CR2016, CR2025, CR2032 coin cell cases crimping without chancing crimping die. Please watch pictures below: Reported by Michelle Huang, AOTELEC Company 2020-02-03

Today is Chinese Traditional Spring Festival, it is the most important day for Chinese, almost all the people back to howntow and celebrate this holidays with families. People will prepare rich foods include pork, duck, chicken and other special delicious foods. And the dinner is most important for today, eating, drinking, wishing are the theme, as well as the lucky money(red packet) to old man and children. Here, AOTELEC (lithium ion battery equipment manufacturer) wish all of our friends and clients a happy new year of 2020!

CR1220 Coin Cell Cases Shipped to Germany According to the requirements of one of our clients from Germany, who bought pressure controlled electric coin cell crimping machine AOT-MSK-160E in year of 2019, we took about 20days to produce and test a new CR1220 coin cell crimping die for that equipment.  Now the crimping die is made and under inspection, we are going to send it out. Meanwhile, we also send 100pcs CR1220 coin cell cases along with the coin cell crimping die. He also had a request of 10mm*1mm size spacer for this application. Here are some pictures for your reference: Reported by Joy Zhang, AOTELEC Company 2020-01-15

Abstract: The patent was developed by Tesla in cooperation with Dalhousie University of Canada. By using new electrolyte additives, the service life of lithium batteries is extended. Recently, Tesla has published a patent claiming that its battery life has been extended to 1.6 million kilometers, which has attracted the attention of a large number of people in the power battery industry. This new type of electrolyte additive is roughly MDO and PDO. The lithium battery prepared is an NMC / graphite pouch battery with high temperature storage and long-term cycling performance. The specific process is that MDO and PDO form an SEI layer on the surface of the graphite electrode, and the prepared battery has better performance than a battery containing VC. At the same time, in the long-term cycle test, the performance of the battery prepared by 2% PDO / 1% DTD and 2% PDO / 1% LFO is also better than that of the battery containing VC. The typical feature of the patent is that when the battery electrolyte additive (lithium salt) of the invention is combined with a non-aqueous solution, the service life and performance of the battery system can be greatly improved. Its battery pack can maintain 95% life after 1000 discharge cycles. Corresponding to lithium batteries without additives, only 25% life. After another 3000 discharge cycles, batteries using additives can still maintain 90% of their life. Tesla also issued a statement saying: "The electrolyte additive method is effective and can extend the life and performance of lithium ion batteries. In recent years, a lot of research has developed such electrolyte additives, such as vinylene carbonate (VC) , Fluoroethylene carbonate (FEC), propadiene-l-3-sultone (PES), ethylene sulfate (DTD), and lithium difluorophosphate (LFO). " This shows that Tesla has a deep scientific research and technical investment in the research of electrolyte additives. All in all, there are at least two implications of Tesley's electrolyte patent. First, the improvement of battery performance can completely seek a breakthrough from the source. For example, attention is paid to the research and improvement of electrolytes, separators, and cathode and anode electrode materials, so as to achieve further improvements and breakthroughs in battery performance. Second, it is urgent to build a car safety production system. Domestic battery companies must ensure that the quality error after the battery leaves the factory is very small and the standardization is extremely high. To meet the performance requirements of end consumers, attention to the manufacturing process and quality control is essential. Reported by Jason, AOT ELEC 2020-01-09

AOTELEC participates in 2019 solid state battery key material technology seminar Time: December 24-25, 2019 Location: Kunshan, Jiangsu From December 24th to 25th, the 2019 High Specific Energy Solid-State Battery Key Materials Technology Symposium was held at the Crown International Convention and Exhibition Hotel in Kunshan, Jiangsu. AOTELEC was invited to participate in the conference. This seminar aims to provide a platform for information exchange for research institutes and R & D and production departments of enterprises, focusing on the industrialization of different electrolyte technologies, and related battery cathode and anode materials in component ratio adjustment, interface modification, and energy R & D and industrialization in advanced directions such as density increase. During the meeting, AOTELEC set up a special promotion booth on the spot, actively discussed and exchanged relevant issues with the participating experts on the perspective of products and services.

On March 13, 2015, two Polish customers made a special visit to inspect our lithium battery raw materials. Accompanied by the sales director, engineers and foreign trade personnel, they had a pleasant and cooperative conversation in the company's eighth floor conference room. Afterwards, the customer visited our company's product and application sample exhibition hall. After learning about our company's scale and seeing the actual product and application samples, the customer gave our company a high evaluation.

According to the requirements of our foreign clients, for them to conveniently see to operate the lab battery equipment when they visit us in our factory, we decided to built a laboratory for customer to know more about our equipment and battery making process. We would like to invite you to visit us and show you most of battery machine in lab, then we can talk details for setting up a battery laboratory in your location.
