LEAD-LEAD OXIDE-CARBON NANOCOMPOSITE FOR ENERGY STORAGE CELLS AND METHOD OF PREPARATION
20210328210 · 2021-10-21 ·

Lead/lead oxide/carbon (“Pb—O—C”) nanocomposite materials are useful as electrode active materials for electrodes in lithium and sodium batteries. A Pb—O—C nanocomposite as described herein comprises Pb and PbOx nanoparticles homogeneously dispersed in a carbon nanoparticle matrix. In the Nanocomposite, the other element or elements (e.g., transition metals, Al, Si, P, Sn, Sb, and Bi) can be alloyed with the Pb nanoparticles, incorporated as a mixed oxide with the PbOx nanoparticles, or can be present as distinct elemental or oxide nanoparticles within the carbon nanoparticle matrix. In some embodiments, the additional element or elements are present as alloys and mixed oxides with the Pb materials and as distinct elemental and/or oxide nanoparticles. In a preferred embodiment the Pb nanoparticles surface is oxidized to PbOx thus creating a shell on core nanostructure.

Bag plate electrodes for lead acid battery
11145855 · 2021-10-12 ·

A novel pair of lead acid battery electrodes are proposed, which are bagged in terelyne cloth bag without having used any pasting to avoid paste mixer, pasting machine and oven etc. By increasing active material ratio to structural material, higher energy density is achieved. Uses of bag system for both negative and positive plate protect the plates from shredding of active materials on use of battery with lesser chance of failure.

Methods and systems for forming mixtures of lead oxide and lead metal particles

According to one or more embodiments presently described, a mixture of lead oxide and lead metal particles may be formed by a method that includes forming a molten metal lead material from a solid lead metal supply material, introducing the molten metal lead material into a reaction zone of a reactor, and contacting the molten metal lead material with an oxidizing gas in the reaction zone to oxidize a portion of the molten metal lead material and form at least solid lead oxide particles and solid lead metal particles. The molten metal lead material may be introduced to the reaction zone in a laminar flow or as atomized molten particles. The weight ratio of formed solid lead oxide particles to solid lead metal particles may be less than 99:1.
