Abstract
A battery with a layers including a first layer which is electrically conductive, a second layer consisting essentially of carbon-fiber-reinforced plastic, a third layer of glass-fiber-reinforced plastic, a fourth layer of carbon-fiber-reinforced plastic and LiFePO4, where the ratio by weight of LiFePO4 to carbon fiber is from 2:1 to 2.5:1, and a fifth layer which is electrically conductive, wherein the battery has substantially been jacketed by a layer made of glass-fiber-filled polyester.
