Effect of Contact Between a Current Collector and a Polyacetylene Electrode on Electrochemical Behavior in Polyacetylene/Lithium Batteries

Abstract: Organic batteries with a polyacetylene film (PA) as the anode, a lithium strip as the cathode, and lithium perchlorate dissolved in propylene carbonate as the electrolyte are constructed. Charging and discharging characteristics of three batteries with different types of PA electrode are investigated. Type a PA electrode involves mechanical pressed contact of nickel gauze with the upper portion of the PA electrode. Charging and discharging of the battery are difficult due to the semiconducting characteristic of the PA. Type b involves a PA film which has one side coated with a sputtered palladium (Pd) film; good contact of the Pd current collector with the PA electrode makes charging and discharging easily manageable. Type c involves an iodine-doped PA film; the battery is easily charged and discharged, but cleaning the surface of the lithium electrode is necessary after a few cycles. 11 references.

Maintenance free lead acid batteries with immobilized electrolyte

Abstract: The reducing of antimony in lead-acid batteries in the last 10 years to optimize the maintenance of the batteries on the other hand was to the detriment of the cycle life. In contrast to antimonyfree batteries in conventional construction the immobilization of the electrolyte by gelatinizing permits the production of sealed batteries with highly improved cycle life, high charge acceptance and deep dischargeability. Moreover those batteries do not have a problem of electrolyte stratification. During charging the O/sub 2/-recombination is approximately 75% depending upon the battery size. Because of the O/sub 2/-recombination in this system a wider range of charging potentials of single cells in the battery takes place, which is characteristic of this system.

Sealed organic battery and its manufacture

Abstract: PURPOSE:To obtain a sealed battery containing absolutely no water by providing the battery, which has a positive and a negative electrode at least one of which is made of an organic conductive material, with a positive and a negative auxiliary electrode, and sealing the battery after moisture contained in electrolyte is electrolyted and discharged from a venting hole by feeding current to said auxiliary electrode. CONSTITUTION:An electrolyte 4, a positive and a negative electrode 3 at least one of which is made of an organic conductive material and auxiliary electrodes 2 are installed in a battery case 5. The electrodes 2 and 3 are connected to lead- out electrodes 1, which airtightly penetrate the case 5. The case 5 is provided with a venting hole 6. With the hole 6 open, potential difference necessary for electrolysis of water is applied across the electrodes 2 until water existing in the electrolyte 4 is completely electrolysed, then hydrogen gas and oxygen gas produced by the electrolysis are discharged from the hole 6. At the point when no bubbles are produced entirely, the hole 6 is closed with a sealing plug 7 to seal the case 5. By the means mentioned above, a battery practically containing no water in its electrolyte and allowing entirely no invasion of moisture from the air, is constituted.
