US Patent:

8455140, Jun 4, 2013
Filed:

May 17, 2012
Appl. No.:

13/473863
Inventors:

Xiaosong Huang - Novi MI, US
Hamid G. Kia - Bloomfield Hills MI, US
Mark W. Verbrugge - Troy MI, US
Assignee:

GM Global Technology Operations LLC - Detroit MI
International Classification:

H01M 2/18
US Classification:

429246, 429247, 429254
Abstract:

A porous polymer separator layer that exhibits a non-uniform cross-sectional thickness and a method of making the same are disclosed. The porous polymer separator layer may be made by a phase-separation process. This process involves precipitating the porous polymer separator layer from a film having a non-uniform cross-sectional thickness similar to that sought to be imparted to the resultant separator layer. An electrochemical battery cell for a secondary liquid-electrolyte battery may incorporate the disclosed porous polymer separator layer between a negative electrode and a positive electrode in a way that that helps maintain a more evenly distributed current density within the cell.

US Patent:

8460591, Jun 11, 2013
Filed:

Mar 23, 2010
Appl. No.:

12/729722
Inventors:

Xiaosong Huang - Sterling Heights MI, US
Hamid G. Kia - Bloomfield Hills MI, US
Assignee:

GM Global Technology Operations LLC - Detroit MI
International Classification:

B29C 67/20
US Classification:

264216, 264 41
Abstract:

The instant disclosure relates to porous membranes and methods of making the same. An example of the method includes exposing a polymeric film (including a polymer and i) a gel-forming polymer, ii) ceramic particles, or iii) combinations of i and ii) established on a carrier belt to a non-solvent or a slightly miscible solvent of a polymer in the polymeric film, thereby inducing formation of a porous structure in the polymeric film. The method further includes transporting the polymeric film on the carrier belt into a bath of a non-solvent or a slightly miscible solvent of the polymer for a predetermined time thereby finalizing the formation of the porous structure and forming the porous membrane. The porous membrane is removed from the non-solvent or slightly miscible solvent bath.

Abstract:

A porous polymer separator layer that exhibits a non-uniform cross-sectional thickness and a method of making the same are disclosed. The porous polymer separator layer may be made by a process that involves forming a film having a non-uniform cross-sectional thickness similar to that sought to be imparted to the resultant separator layer and deriving the porous polymer separator layer from the film.

US Patent:

8470468, Jun 25, 2013
Filed:

Feb 12, 2010
Appl. No.:

12/704694
Inventors:

Xingcheng Xiao - Troy MI, US
Xiaosong Huang - Sterling Heights MI, US
Mark W. Verbrugge - Troy MI, US
Ion C. Halalay - Grosse Pointe Park MI, US
Assignee:

GM Global Technology Operations LLC - Detroit MI
International Classification:

H01M 2/16
US Classification:

429144
Abstract:

A porous polymer sheet or membrane is provided with a thin coating of an electrically non-conductive ceramic composition and the coating conforms to all surfaces, including the pore surfaces, of the membrane. Such a coated membrane serves well, for example, as an intra-cell separator in a lithium ion battery. The coating increases the mechanical properties and thermal stability of the separator in battery operation and retains electrolyte. The coating may be formed by a two-step vapor-phase process in which atoms of one or more metals such as aluminum, calcium, magnesium, titanium, silicon and/or zirconium are deposited in a conformal layer on a workpiece surface. The metal atoms may then be reacted with ammonia, carbon dioxide, and or water to form their respective non-conductive nitrides, carbides, and/or oxides on the surface. The two-step process is repeated as necessary to obtain a ceramic material coating of desired thickness.

Filed:

May 31, 2011
Appl. No.:

13/149205
Inventors:

Xiaosong Huang - Novi MI, US
Assignee:

GM Global Technology Operations LLC - Detroit MI
International Classification:

C08J 9/00
H01M 2/16
US Classification:

521 63, 521 64, 521 91, 429249, 429251, 429252, 429254
Abstract:

A porous thin-film polymer separator for use in a lithium ion battery may be formed by a phase separation method in which hydrophobic-treated ceramic particles are used to help induce the formation of a tortuous, interconnected network of pores coextensively across the thickness of the separator. As part of the phase separation method, a wet thin-film layer is formed from a polymer slurry that comprises a polymer solvent in which a polymer material is dissolved and the hydrophobic-treated ceramic particles are dispersed. The wet thin-film layer is subsequently exposed to a polymer non-solvent to form a solvent-exchanged thin-film precipitated polymer layer which is then heated to produce the separator.

Abstract:

A biodegradable polymeric composition includes 99.5 wt. % to 40 wt. % soy protein and 0.5 wt. % to 60 wt. % of a first strengthening agent that consists essentially of a polysaccharide selected from the group consisting of agar, gellan, and mixtures thereof. The composition is substantially completely soluble in water at a pH of about 7.0 or higher. A biodegradable composite includes a fiber mat and the described biodegradable polymeric composition. A biodegradable molded thermoset solid article is obtained by subjecting the described biodegradable polymeric composition to conditions of temperature and pressure effective to form the thermoset solid article.
