LEAD ACCUMULATOR Russian patent published in 2009 - IPC H01M10/12 H01M2/18 

FIELD: chemistry.

SUBSTANCE: invention relates to chemical cells and can be used in designing and production of lead accumulators. According to the invention, the lead accumulator contains a block of negative electrodes and a block of positive electrodes, divided by separators, on whose sides facing the positive electrodes there are vertical fins, and put into a vessel (monoblock), filled with electrolyte. On the sides of separators, facing the positive electrodes there are also horizontal fins made from material of the separator, the number of which is less than or equal to the number of horizontal electric conductors in the current collector grid of the positive electrode, and their arrangement on the surface of the separator coincides with the arrangement of horizontal electric conductors in the current collector grid of the positive electrode.

EFFECT: prevention of slipping of active material of positive electrodes, provision for efficiency and given operational characteristics of accumulators during use and longer service life.
