GRAPHITE AND DISPERSANT ADDITIVES FOR BATTERY PASTE COMPOSITIONS

Various graphite additives were incorporated into the positive battery paste composition to compare their effects on the positive active mass utilization of lead-acid batteries. The disclosure is related to battery paste composition for preparing a lead-acid battery plate comprising a graphite additive selected from the group consisting of globular natural graphite, natural flake graphite, expanded flake graphite, and combinations thereof. The disclosure is also related to a battery paste composition comprising a sodium polymethacrylate dispersant. The disclosure is further related to batteries prepared by these battery paste compositions.

MULTILAYERED ANODE AND ASSOCIATED METHODS AND SYSTEMS

Described herein are multilayer composite foil materials, as well as methods of making and using multilayer composite foil materials. The composite foil materials can comprise different layers of different metals which may have differing activity toward an active metal, such as lithium. The different layers may allow the composite foil material to include layers that are more active towards the active metal, providing for electrochemical activity, and other layers that are less active towards the active metal, and serving as structural layers. The multilayer composite foils are useful as anodes of electrochemical cells, such as lithium ion cells.
