A mold for molding post and strap in a cast on strap machine includes a mold body having an upper surface, a cavity in the upper surface for molding a strap and an opening aligned with the cavity for receiving a water-coolable insert for molding a post. The opening extends through the mold with its mouth in the upper surface to enable the insert to be inserted into the opening through the mouth. The mold body further includes a removable plate for being received in the mouth to retain releasably the insert in the opening and for defining the cavity.

The present invention discloses a method for lead carbon compression moulding comprising a first stacking step and a first compressing step so that a lead-carbon electrode is obtained through compressing a lead-carbon sandwich stacked of a lead material and a carbon material. Pressurization of the working environment or heating both the lead material and the carbon material is not required during the procedure. A massive production of lead-carbon electrode at room temperature can be anticipated. The lead-carbon electrode produced thereby enhance tolerance of the battery against instable electric current or voltage, and performance remains steady after multiple times of charge-discharge cycles. The lead-carbon electrode produced thereby demonstrates high potentials for application with low cost, low loss and high capacity.

A belt caster wheel assembly for a battery component continuous casting machine. The battery component can be a continuous strip of metal grids or a continuous strip of bipolar metal foils. The belt caster wheel assembly, per an implementation, includes a rotatable caster wheel and a moveable belt. One or more gas vents are established in the rotatable caster wheel. The gas vent(s) fluidly communicates with a mold cavity of the rotatable caster wheel. Gas bubbles, voids, and/or other unwanted imperfections in the ultimately-produced battery components can be partly or entirely resolved with the employment of the gas vent(s).
