The necessity and significance of creating and developing innovative industrial technologies for energy storage 18650 battery 3.7v 1800mah

　　At present, the electric vehicle and hybrid electric vehicle markets are developing slowly and steadily. Qilu said that lithium battery technology and metal resource issues are currently the focus of the industry. As the electrification trend gradually takes shape around the world, the consumption of mineral raw materials for power batteries increases, and resources The layout aspect will be given great attention. In addition, in terms of lithium battery industrial manufacturing technology, there should be a gradual transition to solid-state 18650 battery 3.7v 1800mah. "The current industrialization technology of all-solid 18650 battery 3.7v 1800mah should focus on: 1) the development and application of new inorganic solid electrolytes; 2) not using electrolytes and separators; 3) the development and application of lithium metal anodes; 4) the rapid development of lithium battery cathode materials Diversification," Qilu said.

　　Regarding how to synthesize lithium battery materials with good electrochemical properties, Qi Lu believes that appropriate chemical synthesis methods should be selected, the chemical composition should be accurately determined, and advanced physical and chemical methods and technologies should be used to improve the performance of the materials (physical properties such as surface and particles). At the same time, it is also necessary to test the electrochemical properties of the materials, establish appropriate material performance evaluation methods and systems, and initially study the lithium battery cycle charge and discharge stability and safety of the materials.

　　In addition, Qilu also shared the recent application prospects of 18650 battery 3.7v 1800mah in power energy storage at the meeting. "In China, the cost of photovoltaic and wind power has been lower than 0.3 RMB/kWh, and the nighttime power price in some areas is lower than 0.1 RMB/kWh. Large-scale power energy storage is imperative. In order to solve the problem of peak and valley power and wind and wind restrictions, Regarding photovoltaic issues, the State Power is planning to invest tens of billions to build water peak-shaving power stations. In addition, several new megawatt-level lithium battery energy storage power stations are being designed, and there is an urgent need for cost-effective large-capacity 18650 battery 3.7v 1800mah and feasible designs. Plan." Qilu believes that off-grid lithium battery energy storage and power generation prospects are promising, and cost-effective 18650 battery 3.7v 1800mah are expected to enter the automotive starting power supply market.
