5645949 BATTERY CELL HAVING AN INTERNAL CIRCUIT FOR CONTROLLING ITS OPERATION Young Steven J Milpitas, assigned to Apple Computer
CA, UNnED Inc
STATES
A battery cell having a positive terminal, a negative terminal and a power producing tote section (e.g., electrolyte) for systems, such as computer systems, cellular phones, etc. The battery cell also includes an internal circu.it to monitor the state of the battery cell. The state that is monitored may include the temperature, charge level of the battery core section, the discharge/charge rate. The circuit may control the battery cell (e.g., cause charging of the battery cell). This internal circuit may be an integrated circuit, such as a microprocessor.
PCT No. PCT/JP95/00845 Sec. 371 Date Dec. 21, 1995 Sec. 102(e) Date Dec. 21, 1995 PCT Filed Apr. 27, 1995 PCT Pub. No. WO95/295 10 PCT Pub. Date Nov. 2, 1995. A zinc anode can is formed of a zinc based alloy material including 0.004-0.800 wt % of indium, 0.001-0.25 wt % of titanium or 0.002-0.500 wt c/; of zirconium, without containing significant amounts of harmful substances such as mercury, cadmium, or lead, is provided. A method of manufacturing of such zinc anode can enabling addition of up to 0.800 wt % of indium includes hot rolling of the zinc base alloy in a temperature range of 270-370”~ A manganese dry battery includes a separator on which is coated a paste having 0.1-8 wt % of InC13. The separator is disposed on the inner surface of the zinc can. An interior of the separator is filled with a cathode mixture containing conductive carbonaceous material such as manganese dioxide, and acetylene black and electrolyte with a ZnCl2 concentration of 35-50 wt %. A carbon rod as a collector is inserted into the center of the cathode mixture.

STATES
A device for a battery with a spacer preventing direct physical contact between first and second batteries arranged in physical series. A resilient conductor providing an electroconductive contact between a center electrode of lthe first battery and a terminal electrode of the second battery is held by the spacer.

5648183 ALUMINUM AND SULFUR ELECTROCHEMICAL BATTERIES CELLS
AND
Licht Stuart; Peramunage Dharmasena Charlton City, MA, UNITED STATES assigned to Clark University A battery is provided comprising an aluminum anode, an aqueous sulfur catholyte, and a second electrode capable of reducing sulfur. A polysulfide cathode (for use with the above battery or independently) includes solid sulfur at ambient temperatures, and the cathodic charge stored in that solid sulfur can be directly accessed. An anode (for use with the above battery or independently) is also described, with the ability to utilize a substantial fraction of the anodic charge stored in the aluminum when immersed in electrolytes containing over 10 molar alkaline hydroxide.
