Abstract: The present invention is directed towards a process for making an electrode wherein the process comprises the following steps (a) providing a particulate lithiated transition metal oxide according to the formula Li1+xTM1-xO2 wherein x is in the range of from zero to 0.1 and TM contains nickel and at least one of Co, Mn and Al, (b) mixing the lithiated transition metal oxide from step (a) with carbon in electrically conductive form, (c) exposing the mixture obtained in step (b) to a pressure in the range of from 100 to 500 MPa over a period of time of from one second to one minute, thereby causing cracks in at least some of the particles of the electrode active material, (d) mixing the mixture from step (c) with a binder polymer and, optionally, with further carbon in electrically conductive form and with a solvent, (e) applying the mixture from step (d) to a metal foil.

Abstract: A test system (110) for determining battery performance during development of a battery configuration in a test environment is proposed. The test system (110) comprises at least one communication interface (114) and at least one processing device (122). The test system (110) is configured for receiving operating data indicative of at least one test protocol via the communication interface (114). The test system (110) is configured for receiving battery performance input data via the communication interface (114). The processing device (122) is configured for determining at least one predicted time series of at least one state variable indicative of battery performance based on the battery performance input data and on the operating data using at least one data driven model. The test system (110) is configured for providing at least parts of the predicted time series of the state variable.
