New consumer battery with high energy density

The proposal consists in the development of consumer batteries with high energy density (more than 800 wh/l) using new technology in the field that involves obtaining sodium borohydride gels as active anodic material.

MOST INTERESTING CHARACTERISTICS There are a lot of products used as reducing agents in medication manufacture and other chemical products. The most important industrial applications are the reduction of carbonyls, peroxides and metallic ions as well as the purification and elimination of colour, smell and oxidation precursors in organic chemical products. Nevertheless, these types of products have the disadvantage of low system stability that makes the storage impossible over long periods. One solution comes from stabilising the reducing agent by means of obtaining a gel. The present project proposes the use of high performances of this material (more than 2100 Ah/L of capacity) in an application that does not need the mobility of fuel: a primary or non-rechargeable battery. In a primary battery, commonly used as a consumer battery, the active materials are integrated in the same device. Electrodes and other necessary components extract the electric energy from the chemical compound. Therefore, this kind of gel will be able to be used as anodic material similar to zinc gel used as anodic material in current consumer alkaline batteries. Following a similar procedure, a stabilised gel of high oxidising power compound can be developed for use as cathode material in this new battery. Therefore, the proposal in this project consists in development of consumer batteries with high energy density (more than 800 Wh/L) using a new technology in the battery field. The project will be carried out between the following participants: - MIBD, Israeli company specialised in the manufacture of stable gels from unstable components. - CEGASA (project leader) is the manufacturing company and specialist in consumer batteries. Besides commercialising the obtained product, the company will take charge of material and component characterisation, development of components at pilot-plant scale and integration of these components in consumer battery format. CEGASA has the collaboration of CIDETEC, a technological centre of electrochemistry that will deal with laboratory tests of the gels in order to achieve their optimisation as electrodes of non-rechargeable batteries. It will also take part in the development of low cost catalysts in cooperation with experts from MIBD. Keywords: primary battery, consumer electronics, dry cell.
