The device is refuelled at a zinc recycling/refuelling station where zinc pellets are pumped into each cell. ZnO is pumped from the tank and replaced with KOH electrolyte.

Up until now, the use of primary zinc-air in the portable product market has been problematic because abbreviated operating life caused by water transpiration between the electrolyte and the atmosphere precluded consideration for most applications. The development of a \"diffusion air manager\" technology has addressed this problem making primary zinc-air batteries with operating life suited to portable consumer products possible. A zinc-air battery design incorporating diffusion air manager technology applicable to portable products is examined.","PeriodicalId":368992,"journal":{"name":"Fifteenth Annual Battery Conference on Applications and Advances (Cat.

The phenomenon of charge recovery that takes place under pulsed discharge conditions is identified as a mechanism that can be exploited to enhance the capacity of a cell in a portable communication device. The bursty nature of many data traffic sources suggests that data transmissions in communication devices may provide natural opportunities for charge recovery. We model the data source as a stochastic process and let the cell discharge be driven by such a process. We use a model of a dual lithium ion insertion cell to identify the improvement to cell capacity that results from the stochastic discharge. The insight from this study leads us to propose discharge shaping techniques that tradeoff energy efficiency with delay in power supply.","PeriodicalId":368992,"journal":{"name":"Fifteenth Annual Battery Conference on Applications and Advances (Cat.

Their patented Thin Metal Film (TMF) technology provides innovative battery solutions to a power hungry battery market. Previous publications relative to TMF technology have focused on performance at the cell level.

In addition, primary and secondary zinc-air cells many with substantial amounts of manganese dioxide in the cathode are becoming more common in consumer use. The gain in the past fifteen years in the carbon zinc cells approaches fifteen percent and that in alkaline cells-twenty percent. None the less the progress in zinc-air cells is most impressive as more and more commercial, compact designs appear for special purposes. These cells can produce more service than lithium cells of the same size. Finally the commercial presence of small secondary alkaline zinc-manganese dioxide cells continues. These cells are able to compete on a primary basis on heavy loads and much more obviously as rechargeable cells.","PeriodicalId":368992,"journal":{"name":"Fifteenth Annual Battery Conference on Applications and Advances (Cat.

Improved charge algorithms for valve regulated lead acid batteries 改进阀控铅酸电池的充电算法

Olson","doi":"10.1109/BCAA.2000.838406","DOIUrl":"https://doi.org/10.1109/BCAA.2000.838406","url":null,"abstract":"The cycle life obtained from valve-regulated lead-acid (VRLA) batteries is strongly influenced by the manner in which they have been charged over their lifetime. Although VRLA batteries initially behave similarly to their flooded counterparts, that behavior changes as the batteries age and the oxygen generation/recombination cycle begins to dominate at near 100% full charge. This means that an increasing portion of the applied charge is consumed in the recombination cycle and that more and more overcharge must be applied to maintain full capacity. The overall result is that the battery heats up because of increased overcharge and oxygen generation. Conventional charge approaches attempt to deal with rising temperatures by lowering the current during the overcharge phase. However, this approach does not ultimately prevent capacity loss, and a battery charged thusly typically will yield 200-300 cycles to 50% of initial capacity. The main failure mode appears to be undercharging of the negative plate, not positive-plate corrosion. Two approaches, called partial state of recharge (PSOR) and current interrupt (CI) were successful in extending battery life. PSOR uses nine limited recharge cycles followed by a tenth cycle using 120% charge return. The best PSOR cycle life to date is 1160 cycles to 50% and 800 cycles to 80%. CI uses a high current in the overcharge applied discontinuously to control battery temperature. CI effectively maintains negative-plate capacity, with an Optima group 34 deep-cycle battery yielding 415 cycles to 80% initial capacity and 760 cycles to 50%.","PeriodicalId":368992,"journal":{"name":"Fifteenth Annual Battery Conference on Applications and Advances (Cat.

The condition of the negative electrode, from both new and real-time aged product, has been carefully examined by both electrochemical measurements of the product and also by analyzing the morphology and crystallography of the plates. The condition of the positive grid has also been examined to determine the extent of corrosion. In conclusion, this paper demonstrates that by using a high purity VRLA technology, which has been commercially available for 25 years, it is possible to far exceed 2 years of reliable service. Properly designed batteries using this technology have been proven to deliver greater than 13 years in real-time float service.","PeriodicalId":368992,"journal":{"name":"Fifteenth Annual Battery Conference on Applications and Advances (Cat.
