This invention relates to a current collector grid. The current collector grid is used in high density rechargeable batteries. The current collector grid has a woven mesh of wire of a conducting material such as copper.

The present invention provides a novel Photovoltaic system to generate electricity from solar energy by using a novel diurnal three-step sun-tracker for making extended linear arrays of PV panels, suitably-spaced to avoid inter se shadows, to swivel with the sun as it travels across the horizon during the day for in...

The invention relates to a process and apparatus for applying thin coatings to a conducting metallic web, that may, by way of example, be advantageously employed for anodes and cathodes of rechargeable batteries. Such a coating reduces the inter-facial resistance between the metallic eeb and its adjacent non-conduct...

The invention relates to a process and apparatus for pyrolysis of thin coatings of polymer mixtures on conducting webs. The apparatus comrpises an upper and lower hood with a pair of spaced heated plates disposed therein and such that the web during the step of pyrolysis is in a suspended state. The chamber comprise...
