Lithium polymer batteries utilize a dry polymer which enables them to be manufactured in a greater variety of shapes and sizes than Lithium Ion batteries.

When the boat is under sail, water forced through the duct turns the blades of a small hydroelectric generator that charges a bank of lithium-ion batteries.

The material has both active components, through which lithium ions move when the battery is charged or discharged, and inactive ones that help stabilize the active material and extend battery life.
