Abstract: An energy storage device has a single electrode containing an active material in which repeated charge-discharge changes a first characteristic that is an energy storage amount-potential charge characteristic, and a second characteristic that is an energy storage amount-potential discharge characteristic. An estimation device includes: a storage unit that stores first characteristics, second characteristics, or pieces of V-dQ/dV of the single electrode in accordance with a change in a feature value, which is changed by repeated charge-discharge, or stores as a function of the feature value; an acquisition unit that acquires the feature value of the energy storage device; and a first estimation unit that refers to the first characteristic, the second characteristic, or the V-dQ/dV, or refers to the function on the basis of the feature value acquired by the acquisition unit, to estimate the first characteristic, the second characteristic, or the V-dQ/dV of the single electrode.

Abstract: The invention relates to a method for producing an electrode (E) for an electrochemical cell, in particular for a lithium cell. In order to produce a homogeneous mixture allowing the time-saving, cost-effective production, for example by dry coating, of an electrode (E) with improved properties and/or with a layer thickness significantly greater than 100 μm, for example for vehicle batteries, in particular for electric and/or hybrid vehicles, in said method at least one binder (B) and at least one particulate fibrillation auxiliary agent (F) are mixed in a mixing process with a high shear load, the at least one binder (B) being fibrillated (fB), and at least one electrode component (E1) is then added to the at least one fibrillated binder (B) in a mixing process with a low shear load. The invention also relates to an electrode (E) produced in this manner and to an electrochemical cell equipped with an electrode (E) of this type.

Abstract: A method is provided for determining the state of an electric energy storage unit having at least two pole connections and an electrode. An extension of the electrode assembly and/or of a force exerted by the electrode assembly is detected, a first state variable, representing a first state of the electric energy storage unit is ascertained using the detected extension and/or the force and a first mathematical model is stored. An electric variable of the electric energy storage unit is detected and a second state variable, representing the first state of the electric energy storage unit is ascertained using the detected electric variable and a second mathematical model is stored. The first state variable is compared with the second state variable and the first mathematical model and/or variables ascertained by the first model are/is changed depending on the comparison, and/or the second mathematical model and/or variables ascertained by the second model are/is changed depending on the comparison.
