Claims19
A rechargeable energy storage device comprising:
- an electrolyte;
- and
- a negative electrode comprising:
- a first external layer that is a first electrode material layer ME and a second external layer that is either a second electrode material layer ME or a current collector layer CC, and
- two or more internal layers interposed between the first and second external internal layers, said internal layers comprising one or more electrode material layers ME and one or more porous current collector layers CC,
- wherein said electrode material ME and current collector CC layers forming the first and second external layers and the internal layers are alternated according to the repetition pattern —[CC—ME]—, and
- wherein the first external layer that is a first electrode material layer ME is configured to be in contact with the electrolyte.
