Stronger adaptability: Solid-state batteries can be used in a wide range of environments, including high temperature, low temperature, and humid conditions. Longer lifespan: Solid-state batteries have almost no lithium ion consumption during charging and discharging, resulting in a stable battery capacity over a long period of time. Stronger safety: Solid-state batteries use non-flammable and highly stable solid-state materials, making them safer than traditional batteries. More environmentally friendly: Solid-state batteries contain no liquid electrolytes or flammable materials, making them more environmentally friendly. Overall, solid-state batteries have many advantages and are expected to become the mainstream battery technology in the future. #Solid-state Batteries Machine# Email :tob.amy@tobmachine.com  Skype :amywangbest86  Whatsapp/Phone number :+86 181 2071 5609

There are three types of integrated technology for the power battery of new energy vehicles: CTP, CTC, and CTB. Here are the introductions of these three technologies: CTP (Cell to Pack) technology. This mainly involves eliminating the battery module design and integrating the battery pack directly as a part of the vehicle structure onto the vehicle floor, thereby improving space utilization, reducing weight, and increasing endurance. CTC (Cell to Chassis) technology. This involves integrating the battery cells directly into the car chassis to achieve a higher degree of integration of the body and chassis. This technology further improves integration, reduces the number of components, improves space utilization, enhances structural efficiency, reduces vehicle weight, and increases driving range. CTB (Cell to Body) technology. This is a new battery integration technology proposed by BYD Auto, which achieves the evolution from body-in-white to battery-in-body. When designing and manufacturing the battery pack, the battery system is integrated as a whole with the body, at this point, the blade battery acts not only as a battery but also assumes some of the role of the chassis. With the continuous development of science and technology, the integrated technology of new energy vehicles' power battery is also developing. These integrated technologies aim at improving vehicle energy efficiency and increasing mileage while reducing production costs and improving production efficiency. 

  The current collector is one of the indispensable components of lithium-ion batteries, which can not only carry the active material, but also converge and output the current generated by the electrode active material, which is conducive to lowering the internal resistance of lithium-ion batteries, and improving the battery's Coulombic efficiency, cycling stability, and multiplier performance.   Lithium-ion battery current collector   In principle, the ideal lithium-ion battery fluid collector should meet the following conditions: (1) high conductivity; (2) good chemical and electrochemical stability; (3) high mechanical strength; (4) good compatibility and bonding with the electrode active substance; (5) cheap and easy to obtain; (6) light weight.   Currently, the materials that can be used as lithium-ion battery collectors include metal conductor materials such as copper, aluminum, nickel and stainless steel, semiconductor materials such as carbon, and composite materials.   2.1 Copper collector Copper is an excellent metal conductor with electrical conductivity second only to silver, and has many advantages such as abundant resources, cheap and easy to obtain, and good ductility. However, considering that copper is easy to be oxidized at higher potentials, it is often used as a collector for negatively active substances such as graphite, silicon, tin and cobalt-tin alloys. Common copper collectors include copper foils, copper foam and copper mesh, and three-dimensional copper nano-array collectors.   2.2 Aluminum Collector Although the conductivity of the metal aluminum is lower than that of copper, the mass of the aluminum wire is only half that of the copper wire when delivering the same amount of power, and there is no doubt that the use of an aluminum collector contributes to an increase in the energy density of lithium-ion batteries. In addition, compared with copper, aluminum is more affordable. During the charging/discharging process of lithium-ion batteries, a dense oxide film is formed on the surface of the aluminum foil collector, which improves the corrosion resistance of the aluminum foil, and it is often used as the collector for the positive electrode in lithium-ion batteries.   2.3 Nickel collector Comparatively speaking, nickel is a base metal, relatively inexpensive, has good electrical conductivity, and is more stable in acid and alkaline solutions, so nickel can be used as both positive and negative electrode collectors. It is matched with both positive active substances such as lithium iron phosphate and negative active substances such as nickel oxide, sulfur and carbon and silicon composites. The shape of nickel collector is usually of two types: nickel foam and nickel foil.   2.4 Stainless steel collector Stainless steel is an alloy steel containing elements such as nickel, molybdenum, titanium, niobium, copper, iron, etc. It has good electrical conductivity and stability, and it c...

Battery charging and discharging once is called a cycle, cycle life is an important indicator of the battery life performance. Factors affecting the cycle life of lithium-ion batteries inherent in the root cause, is to participate in the energy transfer of lithium ions in the number of decreasing. The total amount of lithium in the battery does not decrease, but the "activated" lithium ions are less, they are confined in certain places or the transmission channel is blocked, and can not freely participate in the charging and discharging process. Specifically: (1) Precipitation of lithium metal (2) Decomposition of cathode material (3) SEI film on the electrode surface: carbon anode material, during the initial cycle, the electrolyte will form a solid electrolyte (SEI) film on the electrode surface, and the formation process of SEI film will consume lithium ions. (4) Loss of electrolyte (5) Diaphragm blockage or damage (6) Dislodging of cathode and anode electrode materials  Email : tob.amy@tobmachine.com  Skype : amywangbest86  Whatsapp/Phone number : +86 181 2071 5609
