It is reported that the project team has carried out in-depth research and technical research on improving the weight ratio of power battery to energy density and greatly improving cycle life, including the development of new high-nickel cathode materials, silicon-carbon composite anode materials and new electrolytes. The project breaks through the industrialized processing and preparation technology of high energy density batteries, and forms a standardized platform in material development, cell preparation process technology, electrochemical performance and safety performance testing. The research results will be further extended to square and round. Shaped power battery, covering a full range of power battery products.
Two - way trigger diode, also known as two - end ac device (DIAC), and two - way thyristor at the same time.Because of its simple structure and low price, it is often used to trigger the bidirectional thyristor, and can also constitute overvoltage protection circuits.Construction, symbol and equivalent circuit of a bidirectional trigger diode.
Also commonly used in the overvoltage protection, timing, shift equal circuit, Figure 2 is the overvoltage protection circuit composed of bidirectional trigger diode and bidirectional thyristor.When the transient voltage exceeds the DIAC and Ubo, the DIAC quickly conducts and triggers the bidirectional thyristor to also conduct, so that the following load is protected from overvoltage damage.
