CPC, compound parabolic concentration. For this purpose, ZOXY investigated a variety of battery designs to examine the dependence of several performance parameters and found a design, which was denoted as PZ , as most suitable. Test campaigns were conducted with atomized zinc produced from zinc l and with nucleated zinc dust Harzer Zinkoxide. For direct comparison, the same tests were performed with standard zinc sponge. The results of the above exploratory tests are summarized in Table 4 and they appear to be promising in that equivalent performance was recorded for the zinc sponge and for the zinc powder. The nucleated dust typical particle size 2 orders of magnitude smaller also Table 4 behaved similarly, but it required a somewhat higher electrolyte concentration. The reactivity of zinc dust in the electrolyte plays an important role. It depends on the size distribution and on the zinc oxide fraction of the zinc particles. The zinc oxide typically forms a passivation layer around a zinc kernel. The process conditions during quenching of Zn g to zinc dust were adjusted in order to produce zinc dust with a reactivity acceptable for the battery. Results of discharging tests of zincair batteries with different Zn anodes PZ Grillo Powder Author's personal copy Secondary Batteries Zinc Systems Zinc Electrodes: Solar Thermal Production Washing of Spent Zinc Electrodes After battery discharge, one is left with a mixture of zinc oxide, some unreacted zinc, and potassium hydroxide electrolyte. Spent zinc electrodes were washed with water to separate off the potassium hydroxide prior to reusing the zinc oxide in the solar reactor.

Load tries to source rather than sink power, a typical IC voltage regulator will shut down or else. Recoverable chemical energy may still remain. Product details Format Mixed media product pages Dimensions x x Table of contents About Papers Covering: About Professor Jurgen Garche Prof.

In his academic career the focus was on material research. His experience includes also fuel cells mainly low temperature FCs and supercaps. His interest in battery safety goes back to the work with the very large battery safety testing center of the ZSW. Pat was awarded a Ph.

He worked for 23 years at the Harwell Laboratory of the U. Atomic Energy Authority where he brought a background of crystal structure and materials chemistry to the study of lead-acid and other varieties of battery, thus supplementing the traditional electrochemical emphasis of the subject. The nucleated dust typical particle size 2 orders of magnitude smaller also Table 4 behaved similarly, but it required a somewhat higher electrolyte concentration.

Results of discharging tests of zincair batteries with different Zn anodes PZ Grillo Powder Author's personal copy Secondary Batteries Zinc Systems Zinc Electrodes: Solar Thermal Production Washing of Spent Zinc Electrodes After battery discharge, one is left with a mixture of zinc oxide, some unreacted zinc, and potassium hydroxide electrolyte. Spent zinc electrodes were washed with water to separate off the potassium hydroxide prior to reusing the zinc oxide in the solar reactor.

The zinc oxide products resulting from these exploratory tests with zinc powder electrodes were then investigated at WIS and PSI for their performance in the carbothermic zinc oxide reduction process.

Mixtures of washed spent zinc electrodes with beech charcoal powder were found to demonstrate very good reactivity. Option 2 has been developed to a pilot scale for a zinc production rate of 50 kg h1, whereas the others are currently being investigated at the laboratory scale. Preliminary tests have been conducted using solar-produced zinc as the negative active material for zincair batteries, followed by subsequent washing of the spent electrodes after discharging in order to separate the potassium hydroxide electrolyte.

Further development of these solarbased ZnOZn cyclic processes to produce electricity is required. Solar-made zinc nds application not only in zincair batteries but also for hydrogen production via hydrolysis and as a material commodity. Each of these options shows specic advantages and disadvantages with respect to competing technologies.

Thus, further research and development is required to realize commercialization.
