摘要:
A rechargeable battery is provided such that the positive electrode comprises lead dioxide, the negative electrode zinc, iron, lead or cadmium, and the electrolyte is alkaline. Upon discharge, the lead dioxide is reduced to lead oxide, the metal is oxidized to an oxide, and the electrolyte remains unchanged. The reactions are reversed when the battery is charged.

The invention concerns a high-performance tungsten-based super battery system, which relates to an integrated design and a construction method of a corresponding material, a structure and a process. In the technology, a tungsten-based material is used a negative electrode, and a high-specific-surface-area carbon or lead oxide is used as a positive electrode to assemble four types of super batteries comprising: 1) a tungsten-carbon super battery, 2) a tungsten-tungsten super battery, 3) a tungsten- lead oxide super battery, and 4) a super battery system of a hybridized tungsten super battery (comprising lead oxide, lead, and a carbon material) on which the foregoing two types of super batteries are hybridized in use. The introduction of the tungsten-based material endows a novel class of super batteries with higher power density, higher energy density, longer cycling life, high durability and reliable safety. This will enable a broad range of applications.

摘要:
An electrochemical cell and its method of operation includes an electrolyte having a binary salt system of an alkali hydroxide and a second alkali salt. The anode, cathode, and electrolyte may be in the molten phase. The cell is operational for both storing electrical energy and as a source of electrical energy as part of an uninterruptible power system. The cell is particularly suited to store electrical energy produced by a renewable energy source. The positive electrode may comprise a metal selected from Cd, Sn, Hg, Pb, sb, Bi and any cobination thereof, the electrolyte may be a binary salt system comprising an hydroxideand a halide, and the negative electrode may comprise an alkli metal such as sodium (Na).

A rechargeable battery is provided such that the positive electrode (1) comprises lead dioxide, the negative (2) electrode zinc, and the electrolyte (4) is alkaline. Upon discharge, the lead dioxide is reduced to lead oxide, the zinc is oxidized to zinc oxide, and the electrolyte remains unchanged. The reactions are reversed when the battery is charged.
摘要:
An ionic semiconductor material includes 10 to approximately 50 percent by weight of a hydrogel which is dispersed within an inert nonporous matrix material to form a composite wherein the quantity of water that can be absorbed by the composite does not substantially exceed the weight of the composite. The material may be used in electrochemical cells, for water purification, as solid polymeric electrolytes, in breathable waterproof coatings, and in numerous other applications for controlled moisture or ion transfer.
摘要:
A hybrid energy storage device has at least one lead-based positive electrode and at least one carbon-based negative electrode, a separator between the electrodes, a casing which will contain the electrodes and separator, and an acid electrolyte. The separator is gas permeable, and is capable of absorbing and entraining acid electrolyte. The separator has a finite capacity for absorption of acid electrolyte, and the quantity of acid electrolyte which is present in the cell is less than the finite capacity of the separator. Upon assembly of the cell, the casing is sealed, and there is no liquid acid electrolyte within the assembled cell.
