News from John Webb, London Press Service:
[...] The research team was given the task of finding a solution to the problem that conventional lead-acid batteries cannot cope with the high power demands of hybrid cars, and very expensive nickel metal hydride batteries have to be used instead.
The result is a lead-acid battery that is totally different from those in use but promises to significantly cut the price of hybrid cars by eliminating their need to use nickel metal hydride units.
Although it uses acid, there is no free liquid in the Rholab battery. Instead, the acid is absorbed within a glass fibre separator and the individual cells are round, not square, and spirally wound as a Swiss roll.
Each two-volt cell is fully sealed and while technically each of the Rholab battery's four 36-volt modules need only 18 cells, the researchers have cleverly built in a 19th cell that is part of the battery's secret formulation.
