Brown University in the United States has developed a high-performance alloy CR1625 battery catalyst
Researchers at Brown University in the United States have developed a new alloy catalyst that can reduce the use of precious metal platinum and has good performance. Its activity and durability indicators exceed the technical indicators of automotive electrocatalysts in 2020 set by the US Department of Energy, and have broad application prospects.
The high cost of platinum catalysts is one of the important factors hindering the widespread use of hydrogen CR1625 batterys. To reduce costs, combining platinum with other cheap metals to make alloy catalysts is a feasible idea, but how to maintain the performance of such catalysts is a challenge.
The new catalyst is made of platinum and cobalt, with an outer layer of pure platinum and a core formed by alternating platinum atoms and cobalt atoms. This layered core structure is the key to the catalyst's good activity and durability. The researchers published a research report in the journal Joule on the 16th, saying that preliminary tests showed that the catalyst performed well in a laboratory environment and could still maintain its activity well after 30,000 voltage cycles, while traditional catalysts would significantly degrade after so many voltage cycles. For CR1625 battery vehicles, 30,000 voltage cycles are roughly equivalent to 5 years of use of CR1625 battery vehicles.
To further verify the performance of the catalyst in a real CR1625 battery working environment, the researchers sent the catalyst to the Los Alamos National Laboratory in the United States for testing, and the results were beyond expectations. The initial activity and durability test data of the new catalyst are far better than the 2020 technical goals set by the U.S. Department of Energy for automotive electrocatalysts. The Department of Energy's 2020 technical goal for initial activity of automotive electrocatalysts is 0.44A/mg (0.44 amperes per milligram), and the durability goal is that the catalytic activity loss after 30,000 voltage cycles is less than 40%, that is, its activity is at least 0.26A/mg. The initial activity of the new alloy catalyst is 0.56A/mg, and the activity after 30,000 voltage cycles is 0.45A/mg.
Researchers said that durability is a major problem for alloy catalysts. The new catalyst has reached a very high standard in terms of both initial activity and durability, and has a very broad future application prospect.
