This disclosure relates to compositions and methods for improving the performance of batteries, such as lead-acid batteries, including reviving or rejuvenating a partially or totally dead battery, by adding an amount of nonionic, ground state metal nanoparticles to the electrolyte of the battery, and optionally recharging the battery by applying a voltage. The metal nanoparticles may be gold and coral-shaped and are added to provide a concentration within the electrolyte of 100 ppb to 2 ppm or more (e.g., up to 5 ppm, 10 ppm, 25 ppm, 50 ppm, or 100 ppm). The metal nanoparticles may be added to battery electrode paste applied to the electrodes to enhance newly manufactured or remanufactured batteries.

The present invention provides a conductive paste for positive electrodes of lithium-ion batteries and a mixture paste for positive electrodes of lithium-ion batteries that are inhibited from increasing in viscosity and gelling, and that have an easy-to-apply viscosity. The conductive paste of the present invention contains a dispersion resin (A), polyvinylidene fluoride (B), conductive carbon (C), a solvent (D), and a dehydrating agent (E).

Embodiments of the invention provide batteries, electrodes, and methods of making the same. According to one embodiment, a battery may include a positive plate having a grid pasted with a lead oxide material, a negative plate having a grid pasted with a lead based material, a separator separating the positive plate and the negative plate, and an electrolyte. A nonwoven glass mat may be in contact with a surface of either or both the positive plate or the negative plate to reinforce the plate. The nonwoven glass mat may include a plurality of first coarse fibers having fiber diameters between about 6 μm and 11 μm and a plurality of second coarse fibers having fiber diameters between about 10 μm and 20 μm.

A system, apparatus and method for cutting battery grids or plates from a continuous strip of a plurality of connected battery grids. The continuous strip moves toward a rotating cutter with at least two cutter blades with cutting edges equally circumferentially spaced apart and extending parallel to the cutter axis of rotation and a rotating cooperating anvil. The cutting edges and the anvil are rotated at the same tangential speed to cut in a nip between them a plate or grid from the continuous strip of connected grids. At a point upstream of the cutter, an electric signal indicative of each lug of the grid of the continuous strip moving past this point is used to control the speed of movement of the strip through the nip to cut a plate or grid from the continuous strip at a longitudinal speed which is essentially the same as the tangential speed of the cutting edges.
