A method of maintaining the performance level of an electrochemical cell is described. The cell usually includes a negative electrode that includes an alkali metal; a positive electrode that includes at least one transition metal halide; a molten salt electrolyte based on an alkali metal haloaluminate; and a sodium ion-conducting solid electrolyte partitioning the positive electrode from the negative electrode. The method is based on a treatment regimen that includes the step of applying a series of electrical cycles to the cell, wherein the series includes at least one deep discharge of the cell. Each discharge of the cell is usually followed by recharging the cell to its available capacity.

Method for maintaining the performance level of an electrochemical cell

An optoelectronic device assembly can include: a coated element and an electroactive cell on the coated element, wherein the electroactive cell is selected from the group consisting of a light emitting diode and a photovoltaic cell. The coated element can include: transparent thermoplastic substrate and a protective weathering layer. The transparent thermoplastic substrate can include a material selected from the group consisting of aromatic polycarbonate and polyester, and combinations including at least one of the foregoing materials. The protective weathering layer can have a UV absorbance loss rate at 330 nm of less than or equal to 0.15 A/year as estimated from filtered xenon arc exposure and/or having a rate of erosion of less than or equal to 5 &#x3bc;m per year as estimated from filtered xenon arc exposure.
