The present invention describes an electromechanical exercise machine that simulates the inertia and weight of a mass in Earth's gravity field and allows a user to move said simulated mass in the primary degrees of freedom of a traditional barbell free-weight system, with or without the use of various accessories.

Electromechanical physical resistance device

The present invention relates to the application of a force to enhance the performance of an electrochemical cell. The force may comprise, in some instances, an anisotropic force with a component normal to an active surface of the anode of the electrochemical cell. In the embodiments described herein, electrochemical cells (e.g., rechargeable batteries) may undergo a charge/discharge cycle involving deposition of metal (e.g., lithium metal) on a surface of the anode upon charging and reaction of the metal on the anode surface, wherein the metal diffuses from the anode surface, upon discharging. The uniformity with which the metal is deposited on the anode may affect cell performance. For example, when lithium metal is redeposited on an anode, it may, in some cases, deposit unevenly forming a rough surface. The roughened surface may increase the amount of lithium metal available for undesired chemical reactions which may result in decreased cycling lifetime and/or poor cell performance. The application of force to the electrochemical cell has been found, in accordance with the invention, to reduce such behavior and to improve the cycling lifetime and/or performance of the cell.

Application of force in electrochemical cells

An electrochemical cell including a folded electrode layer and a folded separator, a battery including the electrochemical cell, and methods of forming the electrochemical cell and battery are disclosed. The electrode layer is folded in a first direction and the separator is folded in a second direction, such that the first direction and second direction are orthogonal each other.
