As is known to all, the global IC industry has been under the "shining" of Moore's law along the route on silicon, but when the mainstream development of CMOS technology to 10 after nanometer technology nodes, the subsequent development of more and more from the laws of physics and the limitation of the manufacturing cost, Moore's law could face the endOn January 20, top scientific journal Nature published practice spear and physical electronics research institute of Beijing university professor Peng, deputy director of the Mr.

The lithium battery has a large scale into People's Daily life, however, it come from? The lithium battery production process and what link? Although lithium battery depending on different production process lithium battery manufacturers and there are some differences, but due to the same principle, and main lithium battery production process is the basic consistent, generally are: ingredients, coating, rolling, cutting, slitting machine, welding pole ear, winding, encapsulation, baking, filler, rabin, molding, capacitance detection processIn the lithium battery production process and essential step, from material to the forming of the capacity test should pay attention to five aspects of problems:A across the electrodes, the improvement of the material structure of the active material, it is fundamental for lithium battery production process:1, proper ion doping on the material, 2, improve the particle size distribution of active material, avoid the particle size distribution of the active material is too wide, 3, use as far as possible with disordered layered structure or structure with thin layer of material, 4, improving the structure of the surface of the electrode material;Second, the electrode coating with high bond strength is beneficial to decrease the rate of circulation capacity declined, this is the most technical content in the lithium battery production technology process, therefore should pay attention to:1, the formation of binder and the solvent adhesive material to pure, pasted plate also shoulds not be too long, 2, anode coating mixture is used in the adhesive and the ratio of active material to appropriate, to ensure not to drop after coating powder, not to take off powder;Third, the optimization of electrolyte, lithium battery production process is to keep the capacity to the requirement of the electrolyte, extend battery life:1, through the optimization of lithium salts, solvents and additives, improve the electrolyte conductivity, decrease the polarization, the reaction of 2, inhibition of the anode materials and electrolyte, 3, by controlling proper specific surface area and carbon anode materials for coating, surface treatment such as film and the surface chemical reaction, improve the surface of the anode materials structure;Four, battery material preparation, after the completion of the lithium battery production process into assembly link, at this time to pay attention to:1, the cathode capacity slightly greater than the positive capacity, after 2, winding is negative and the diaphragm, form the positive and negative pole piece and the diaphragm of the gap between the three size no greater than 0.

The battery life is the development of wireless sensor nodes is an important consideration, it will constitute the Internet of things (IIoT)In many applications, sensor nodes need to install in inaccessible location, not to mention the service.

Battery as now stored energy, has become an important part of power supply to provide, in the process of electric bicycle use play a crucial roleThe stand or fall of an electric bike running status, many cases are quality has a direct or indirect contact with battery, so, today, all electric truck, electric stacker has become important configuration forklift battery, and in the later in the process of using proportion also gradually expanding.

Since the smartphone screen bigger, mobile life became the object of a lot of people complain aboutAnd fast charging technology naturally became the savior, help mobile phone manufacturer alleviate the problem of life.

According to the ministry of industry and the request of "auto industry long-term development planning, power battery monomer energy density in 2020 to 300 wh/kg, it become the lithium electricity industry efforts to one of the goals of the researchAnd domestic battery enterprise at present the mainstream of the materials used, such as NCM111, NCM523, etc.

On May 8, 2018, the government of Jiangyin city and high-tech zone administrative committee and Beijing linkage physical science and technology co, LTD.

The reporter learned from the Ningbo Institute of Materials of the Chinese Academy of Sciences that the research team of the institute recently developed an aluminum air battery power generation system based on graphene air cathode The energy density of the battery system is up to 510Wh/Kg (watt hour per kilogram), capacity is 20 kWh, and output power 1000 watts.

After bidding farewell to Changxin Technology, Shenzhen BAK Power Battery Co, Ltd.

From the form of the all-solid lithium secondary battery, it can be divided into two types of a film type and a large capacity type The cell packaging technology of all types of all-solid lithium batteries is similar, and the main difference lies in the preparation of pole pieces and electrolyte membranes.
