Last year, 21 teams of battery researchers from all over the world participated in the measurement test. Each of them was assigned to build a solid condition battery using their own devices and commercially available materials with a unified setting procedure. Although the same instructions are used, the performance of the batteries, and the process used to build them, differ greatly through laboratories.
Fans of the TV bread, known for this scenario, may recognize this scenario. Every week, Bake The contestants are given the same ingredients, equipment and recipe and their creations are judged against each other. Although bakers follow the same basic procedure, the results are often completely different because the main steps are left outside the recipe, including mixing techniques, oven temperature and bread time.
Research cloning is not much different. In the battery measurement test, it left the difference to reach its techniques using the equipment and its favorite components to create the electrochemical cells that occupy its batteries. The basic setting requires the separation of two poles by electrolyte, which helps to transfer electrons from one pole to the other to convert chemical energy into electrical energy. The most common composition between the test sets ensures that the solid electrolyte between two active electrical substances is placed, all compressed together by two metal printers. I inside the cell change on the basis of the equipment used. When the performance of the batteries was tested, there was a great difference at the first discharge, ranging between 21 and 143 mm per gram of battery materials-enough energy to run a small LED light for a few minutes for a fitness tracker that can be worn for a day or so.

The team behind the experiment, led by Nella Vargas Barbosa, a electrochemical scientist at the University of Bayrywith in Germany, says the results emphasize the need for more monotheism in battery research. In a paper I published Nature energy1The team recommends that the future solid -solved batteries research the pressure used in construction to help others reproduce the work.
The standard exercise follows a similar study, operating as part of a UK -based project called Nextrode. Five British universities were independently required to build electrochemical cells using the same way they enjoy each other. Dennis Kuming, a battery researcher at Sheffield University, UK, who supervised the experience that taking various measures to ensure that the teams were following the same steps and did not affect each other in any way. He says: “We had everyone around the country doing it at the same time on the same day of a week,” to stop the teams that were transferred on tips and tricks.
The results have not yet been published, but Cumming says that the failure rate between 120 cells was highly: many short circles or properly charging and unloading. “It is very difficult to unite these operations – very difficult – because there are many variables,” says Koming.
The problem is not only that there are many ingredients inside the battery that may be made slightly different and with slightly different properties. Coming says it is very difficult to reach enough raw materials of the same quality. He adds that even commercial materials can differ from payments to payments, and most laboratories do not have the tools needed to measure this contrast. As there are no standard methods that every person adheres to the battery development. There is no standard data set to compare the results versus, there is no standard way to create components, and there is no standard formulation of materials that enter the cell. These types of standards to the field will require a person to pay and pay for work.
No standard
Simon Clark, a sustainable energy researcher at the Norwef Institute in Trondheim, says battery research can learn from the field of biomalia. “When it comes to re -coordination, monotheism and openness to data, vital informatics was the field that he adopted very early,” he says. In the seventies of the last century, biotechnology researchers have increased access to their databases, and used uniform formats. Therefore, when Clark runs that the team behind the Alphafold FunTificial Intelligence (AI), which was developed by Google Deepmind to predict protein structures, “they do not have to start from scratch,” says Clark.
The battery data has not been collected, in comparison, strictly over the past fifty years, because the field is based on the efforts of individual laboratories, and each of them develops their own interests in materials, manufacturing or basic electrical chemistry.
Clark was part of the battery data genome, an international cooperative project launched in 2022 to improve data collection, participation and unification in battery research through open source and best practices. In a paper published in Jolly2Which identified the principles of the project, the authors realized that it would take some time for the research community to accept their ideas, but they argue that the change is required urgently if the transmission of clean energy occurs. “The danger is not to move forward, but in staying as we are now,” they write.

Other battery researchers feel pressure to make the field more powerful. For example, Battery2030+ connects to Europe and Faradai’s battery challenge to the UK, which links research institutions, financiers and public financiers to develop better batteries, and emphasizes the importance of common protocols and methodologies to ensure consistency, safety and efficiency through the batteries industry.
This is also the main axis of Battery500, a consortium consisting of 14 national laboratories and universities in the United States aimed at identifying promising battery materials and accelerating their marketing. As part of the project, researchers at the National Northwestern Laboratory in the Pacific Ocean in Rachelland, Washington, where the 500th battery headquarters, has developed uniform protocols to test each component of the battery during construction.
The consortium has also assigned parameters for the optimal quantity from the electricity of the electricity; The optimum amount of active materials, such as lithium, to be applied to cathode; And the optimum thickness of the lithium chip3. Hundreds of times the papers were cited, indicating that other researchers are following their progress and applying these protocols to their own systems.
The publishing world can also help promote monotheism. In early 2021, Jolly It has provided a battery reference list, which must be completed by researchers who want to spread the results of the battery performance in the magazine. “When I was a student of high studies working in Li -Ion batteries, I often found myself in the additional information department in the papers, and I am looking for experimental details that allow me to repeat an experience,” then Alexandra Stephen JollyWritten in an editorial on the review list4.
Stefan notes that the main details such as the composition of the electrode may sometimes be missing from the sheet. “It was an incredibly frustrated experience,” she wrote.
