摘要： A bipolar lead acid battery with increased energy density is provided. The battery includes a number of lead acid wafer cell that each comprise a negative electrode having a negative electrode plate and a negative active material positioned on the negative electrode plate, as well as a positive electrode having a positive electrode plate and a positive active material positioned on the positive electrode plate. The positive electrode plate comprises a metal foil with a conductive film thereon, such as a titanium foil or substrate with a titanium silicide coating thereon. The lead acid wafer cell also includes a separator between the negative and positive electrodes, wherein the separator includes an electrolyte for transferring charge between the negative and positive electrodes.

摘要： A system and method for providing a ceramic-based separator onto an electrode is disclosed. A separator is formed on the electrode via a dry, solvent-free application of a ceramic-based separator to the electrode. An electrode is provided to an application area via a feed mechanism and a separator layer is then applied to the electrode that is comprised of a binder including at least one of a thermoplastic material and a thermoset material and an electrically non-conductive separator material, with the separator layer being applied to the electrode via a dry dispersion application.

摘要： New wireless devices need better batteries, more powerful but still low cost. We have created one—a high-performance lithium-based battery using metal foam (or some other three-dimensional, fillable, conductive material) to make its electrodes. Our battery offers as much as 30% to 100% greater power and energy density. Similar increases in power and energy density typically increase costs tens or hundreds of times. Our increased performance adds no extra cost. Metal foam increases conductivity within the electrode. So electrodes can be made much thicker, but no more resistant. Thicker electrodes bring more power and more energy for the same volume and weight. Our high-performance, low-cost batteries can be used for small wireless devices like smart cards, for larger mobile devices like cell-phones, and even the high-power, high-energy batteries needed for cars. At all sizes, we provide more power and energy at the same cost.
摘要翻译： 新的无线设备需要更好的电池，更强大但仍然是低成本。 我们已经使用金属泡沫（或一些其他三维，可填充，导电材料）制造了一个高性能锂基电池来制造其电极。 我们的电池提供高达30％至100％的功率和能量密度。 功率和能量密度的类似增加通常会增加数十或数百倍的成本。 我们增加的性能不会增加额外的成本。 金属泡沫增加电极内的电导率。 所以电极可以做得更厚，但没有更多的阻力。 较厚的电极为相同的体积和重量带来更多的功率和更多的能量。 我们的高性能，低成本电池可用于诸如智能卡之类的小型无线设备，适用于大型移动设备（如手机），甚至汽车所需的大功率高能量电池。 在各种规模下，我们以相同的成本提供更多的电力和能源。
