Continuous methods of making microporous battery separators

A continuous method of making dry-stretch microporous membrane battery separators from polypropylene (PP) or polyethylene (PE) or both benefits to the manufacturers in the production efficiency. The precursor-film extrusion in this invention is accomplished by multiple small film-extrusion lines at a compatible line speed with the followed oven processes (annealing and stretching). The overall production process starts continuously from film extrusion to annealing and to stretching. The benefits of the inventive continuous process includes a higher product yield, more effective oven-time usage, no need to handle and manage the intermediate products, less need in labor and machine maintenance, and potentially more stable product quality.
The dry-stretch membrane separators made with this inventive continuous method include (1) single-ply PP or PE separators having a thickness ranging from 0.2 mil to 2.0 mil; (2) PP/PE/PP trilayer microporous membrane separators having a thickness ranging from 0.6 mil to 4.0 mil. The PP/PE/PP trilayer can be accomplished in the early extrusion via either co-extrusion or extruding separately and then interposing PE layer between two PP layers, continuously, right before annealing/bonding and stretching process.

Copper foil production conjoint machine and high-bonding strength copper foil technology for lithium ion battery

The invention discloses a copper foil production conjoint machine and a high-bonding strength copper foil technology for a lithium ion battery. The copper foil production conjoint machine comprises a foil production machine and a post-treatment machine. The post-treatment machine is connected to the back of the foil production machine. A straight-line distance between a treatment tank copper foil input roller of the post-treatment machine and a copper foil stripping roller of the foil production machine is less than or equal to 3m. A rough treatment anode plate and a curing treatment anode plate are arranged along two surfaces of copper foil in a pre-treatment tank of the post-treatment machine. A post-treatment process comprises carrying out double-surface rough treatment, curing treatment, passivation treatment and washing treatment on copper foil which is fed by the foil production machine and has double-surface roughness vales of Rz less than 1.7 micrometers and Ra less than 0.25 micrometers. Through utilization of a copper sulphate solution as a roughing solution and a curing solution, the production flow is simplified; the control process is simple and can be operated simply; and a yield is improved. The copper sulphate solution does not contain an arsenic compound, reduces pollutant discharge, is conducive to environmental protection, and has obvious economic and social benefits.

Method for Centering Reciprocating Bodies and Structures Manufactured Therewith

Methods for assembling a reciprocating body, such as a piston, within a bore using a design are described. The piston is substantially centered within the bore and then connected at one end through a rotational coupling to a substantially laterally fixed structure connected to the bore such that during normal operation the piston can rotate within the bore along the bore axis of symmetry but can no longer move laterally. Before fixing the rotational coupling, the piston is connected to an external gas source and substantially aligned along the bore axis of symmetry by a gas bearing having one or more gas bearing ports disposed toward the bore. During normal operation, the gas bearing provides a rotational force sufficient to realize a non-frictional bearing between the piston and the bore. The method of assembly is particularly useful in the assembly of Stirling cycle cryocooler comprising a piston, a compressor bore, adapted to contain the piston, a gas inlet to the piston, a plurality of gas bearing ports located within the piston and disposed toward the compressor bore, the gas inlet being in fluid communication with the gas bearing ports, a rotational coupling structure attached to one end of the piston, and a substantially laterally fixed structure affixed to the compressor bore and the rotational coupling structure.
