Title: Charging of electrochemical storage cells
IPC: H01M10/34
Filed: 1973-05-31
Abstract: 1434588 Charging alkaline storage cells SAFT-SOC DES ACCUMULATEURS FIXES ET DE TRACTION 31 May 1973 [31 May 1972] 25963/73 Heading H1B In a method of charging, without the liberation of hydrogen, an alkaline electrolyte silver oxide-zinc or nickel hydroxide-zinc storage cell, in which the active negative substance is mostly in the form of zincate dissolved in the electrolyte when the cell is discharged, the charging time is limited to being less than or equal to the time, called the transition time, it would take, at the particular charge rate, for the rate of zinc deposition on the negative electrode to be limited solely by the steady state diffusion of zincate ions to the electrode, the charge current intensity being such that the rate of reduction of zincate ions is greater than the diffusion of the zincate ions to the surface of the negative electrode. Since, when charging, the undesirable secondary reducing reaction which produces hydrogen only occurs if there are less zincate ions diffusing to the negative electrode for reduction than the charging rate can deal with, the charging is stopped before this situation arises. The diffusion rate of zincate ions is dependent on their concentration gradient in the electrolyte, and during the charging this concentration at the electrode decreases from an initial value M o  to a value M e  (which may be zero). Thus there is set up a concentration gradient from M e  at the electrode to M o  at a certain distance from the electrode-the layer of concentration gradient thus defined being called the diffusion layer. A steady state situation is set up which limits the thickness of this layer and the time taken for the limit value of this diffusion layer to be reached is the transition time. In practice the maximum value of the diffusion layer thickness is 0À4-0À5 mm., and a further feature of the invention is the preferred limitation of the total volume of electrolyte in the cell to that defined by the limit of the diffusion layer thickness and the total area of the negative electrode. The zinc electrode support may be of solid silver or of porous sintered silver having a pore size less than double the thickness of the corresponding diffusion layer and a porosity greater than 50%. Preferably the charge current intensity is between 100 and 1000 times the electrochemical capacity of the negative electrode, and may, for example, lie between 5-40 amps. per dm.<SP>2</SP> of negative electrode. The limit ot the charging time may be calculated or may be determined by monitoring the potential difference between the electrodes of the cell or between the negative electrode and a reference potential. A number of specific examples are given.

Abstract: 1422586 Integrated circuits INTERNATIONAL BUSINESS MACHINES CORP 1 June 1973 [30 June 1972] 26208/73 Heading H1K Laterial isolation of surface-leakage sensitive semiconductor circuit elements in an integrated circuit is effected by insulating barriers 18 extending through a P--type epitaxial layer 11 and into a P<SP>+</SP>-type substrate 10, the substrate 10 providing a common terminal for all the circuit elements. For a Si structure the barriers 18 are preferably of SiO 2  formed by selectively oxidizing part of the thickness of the epitaxial layer 11, etching the oxide so formed to provide grooves and oxidizing the material exposed in the grooves. The upper surface of the barriers 18 is preferably flush with that of the epitaxial layer 11. Amonst the devices which can employ this form of isolation are charge-coupled devices, field-induced capacitors, dynamic storage cells and dynamic logic cells using FETs. Fig. 11 (not shown) illustrates a pair of IGFETs, one having a metal gate (34) and the other a polycrystalline Si gate (19), located in adjacent islands of the epitaxial layer (11) and separated by an oxide barrier (18). Fig. 12 shows an IGFET having four channel regions 44, 43, 45, 47 in series, each beneath a corresponding gate electrode of which the first and third 42, 46 are of metal and the second and fourth 19 are of polycrystalline Si. Diffused source and drain regions 40, 41 abut the oxide barriers 18. Fig. 10 shows two adjacent memory cells in a memory array provided with diffused N<SP>+</SP>-type bit lines adjacent isolation barriers 18, and orthogonal Al ward lines 27. Each cell includes an IGFET constituted by a bit line 22 as source, a channel region 23 of the epitaxial layer 11, a Si 3 N 4 -on-SiO 2  gate insulation 16 and part of the ward line 27 as gate electrode. Charge conducted through the channel region 23 is stored in a capacitor constituted by a polycrystalline Si electrode 19, part of the insulation 16 and the underlying area 20 of the epitaxial layer 11. The polycrystalline Si electrode 19 is separated from the overlying Al ward line 27 by an oxide layer 24, and a similar layer isolates the ward line 27 from each bit line 22 except where contact is required to be made. The capacitor electrodes 19 may alternatively be made of a refractory metal. A method of manufacture using conventional planar processing steps is described.

Abstract: 748,463. Measuring osmotic pressure electrically. NATIONAL RESEARCH DEVELOPMENT CORPORATION. Sept. 16 1954 [Sept. 24. 1953]. No. 26302/53. Class 40(1) [Also in Group XIX] Apparatus for measuring the osmotic pressure between an aqueous colloidal solution and the solvent located on either side of a semi-permeable membrane, comprises a diaphragm arranged on the solvent side of the membrane which is connected by a rigid link to the movable anode of a triode valve assembled in a bridge circuit, a measured external pressure being applied to the colloidal solution until the diaphragm is not moved when the solvent is applied to the one face or cut off. As shown (Fig. 2), the solution is contained in a glass tube 10, and the solvent in a glass tube 11, both located in holes in a stainless steel block 12, resting on a further stainless steel block 14, the holes in block 12 being continued as smaller diameter coaxial holes 20, 23 in the block 14, but separated by a semipermeable membrane 15, which is perforated above hole 23, and stretched at the top of hole 20 by a circular, domed, stainless steel support 16, closely ribbed on the upper surface and with intersecting grooves across the upper and lower surfaces inter-connected at the peripheral edges. The hole 20 is enlarged into a cone containing a diaphragm 42 in its base, the upper part of the cone being connected via passages 24, 25, 36, 28 (Fig. 3) to the passage 23 the connections being closable by lateral movement of a slide valve 30, produced by screws 31. Below block 14 is mounted a transducer valve 39 with a movable anode connected by rods 40, 41 to the centre of diaphragm 42. The tube 39 constitutes one arm of a bridge circuit, so that movement of the diaphragm 42 is indicated and measured. In operation equal levels of solution and solvent are placed in the tubes 10, 11 and a measured pressure is applied to the liquid in tube 10 via pipe 57 so that diaphragm 42 maintains the same position when the slide valve 30 opens or closes the passage between holes 20, 23. Alternatively, a graph of external pressure against unbalance current for a given time of opening the passages may be plotted, when the subsequent readings of current for a known external pressure and the same time enable the. pressure for zero unbalance current, i.e. the osmotic pressure, to be obtained. In a modification the transducer may be a variable capacitor or inductor housed behind the diaphragm 42.
