Tin And Tin-Zinc Plated Substrates To Improve Ni-Zn Cell Performance

View page
US Patent:
20090090636, Apr 9, 2009
Filed:
Oct 5, 2007
Appl. No.:
11/868337
Inventors:
Feng Feng - San Diego CA, US
Jeffrey Phillips - La Jolla CA, US
Sam Mohanta - San Diego CA, US
Jeff Barton - San Diego CA, US
Zeiad M. Muntasser - San Diego CA, US
Assignee:
POWERGENIX SYSTEMS, INC. - San Diego CA
International Classification:
C25D 3/30
C25D 3/22
H01M 4/42
US Classification:
205300, 205305, 429229
Abstract:
An improved Ni—Zn cell with a negative electrode substrate plated with tin or tin and zinc during manufacturing has a reduced gassing rate. The copper or brass substrate is electrolytic cleaned, activated, electroplated with a matte surface to a defined thickness range, pasted with zinc oxide electrochemically active material, and baked. The defined plating thickness range of 40-80 μIn maximizes formation of an intermetallic compound CuSn that helps to suppress the copper diffusion from under plating layer to the surface and eliminates formation of an intermetallic compound CuSnduring baking to provide adequate corrosion resistance during battery operation.

US Patent:
6383395, May 7, 2002
Filed:
Jan 4, 2000
Appl. No.:
09/477501
Inventors:
Stephen R. Clarke - Orinda CA
Richard J. Clarke - Orinda CA
Roderick Murdock - Canyon CA
Clive J. Butler - Easton PA
Sam Mohanta - Fremont CA
Assignee:
Luxfer Group Limited - Manchester
International Classification:
C02F 128
US Classification:
210683, 210684, 210688, 210226, 210228, 210266, 210282, 210484, 2104931, 210911, 210913, 210915, 210679
Abstract:
A media is used to remove species from aqueous solutions, particularly in the treatment of water to enable it to be suitable for drinking. The media includes a material selected from the group consisting of zirconium hydroxide, titanium hydroxide, hafnium hydroxide and combinations thereof. A preferred form of the media is a layer having an aspect ratio of at least 1:1, more preferably, at least about 10:1. Removed from the water are species selected from the group consisting of arsenate, selenate, chromate, borate, perchlorate, fluoride and combinations thereof. In particular arsenite (As ) containing species are also removed from water. Arsenite may be removed from water to levels not greater than 10 parts per billion with a single exposure to the media. The media is selective for certain species over others. The arsenite component is removed despite a presence of at least one competing species selected from the group consisting of sulphate, phosphate, nitrate, bicarbonate, iron, carbonate, nitrite, silicate, sulphite, chloride, bromide and iodide.
