Embodiment Construction

[0011] figure 1 An illustration of the energy storage device 10 according to the disclosed exemplary embodiment is provided. The energy storage device 10 may include various types of batteries. For example, in one embodiment, the energy storage device 10 may include a lead-acid battery. However, other battery chemistries can be used, such as those based on nickel, lithium, sodium-sulfur, zinc, metal hydrides, or any other suitable chemistry or material that can be used to provide electrochemical potential.

[0012] Such as figure 1 As shown in, the energy storage device 10 may include a housing 12, a terminal 14 (only one is shown), and a unit 16. Each unit 16 may include one or more positive plates 18 and one or more negative plates 19. In a lead-acid battery, for example, the positive electrode plate 18 and the negative electrode plate 19 may be stacked in an alternating manner. In each unit 16, a bus bar 20 may be provided to connect the positive plates 18 together. Similar ...

Abstract

An electrode plate for an energy storage device includes a current collector fabricated at least partially from an electrically conductive phosphate glass. A chemically active material may be disposed on the current collector.

Description

Technical field [0001] This application mainly relates to materials used for components of energy storage devices, and more specifically, to phosphate glass components used for lead-acid batteries. Background technique [0002] There are various types of batteries. Many of these battery types store and release electrical energy by using the potential difference provided by certain electrochemical reactions. In lead-acid batteries, for example, each unit includes a stack of alternating positive and negative plates. Each of these plates includes a current collector and a chemically active material provided on the current collector. An electrochemical reaction occurs in the chemically active paste, which generates electrons that enable the battery to operate. The current collector collects the electrons produced by the electrochemical reaction and transports these electrons as current to the network of conductive elements associated with the battery. Finally, the network of conducti...
