摘要： 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.

摘要： A battery separator has performance enhancing additives or coatings, fillers with increased friability, increased ionic diffusion, decreased tortuosity, increased wettability, reduced oil content, reduced thickness, decreased electrical resistance, and/or increased porosity. The separator in a battery reduces the water loss, lowers acid stratification, lowers the voltage drop, and/or increases the CCA. The separators include or exhibit performance enhancing additives or coatings, increased porosity, increased void volume, amorphous silica, higher oil absorption silica, higher silanol group silica, reduced electrical resistance, a shish-kebab structure or morphology, a polyolefin microporous membrane containing particle-like filler in an amount of 40% or more by weight of the membrane and ultrahigh molecular weight polyethylene having shish-kebab formations and the average repetition periodicity of the kebab formation from 1 nm to 150 nm, decreased sheet thickness, decreased tortuosity, separators especially well-suited for enhanced flooded batteries.

摘要： An improved lead acid battery (LAB) battery may provide high charge acceptance and may be suitable for a wide range of applications, including a variety of new applications. The new battery can sustain 67% of the maximum capacity even at a very high charging rate of IOC. This battery may decrease the use of lead in comparison to prior lead acid battery designs by up to 50%.
