5 Due to its inherent safety, eco-friendly materials, longer lifespan, and higher discharge power Sony selected Iron Phosphate cell for its Energy Storage System Materials Format Cathode Anode Electrolyte Benefit G-Series Cylindrical / Prismatic Cobalt Graphite Carbon Organic Electrolyte High Capacity Nexelion Cylindrical Cobalt Tin Based Amorphous Organic Electrolyte High Capacity V-Series Cylindrical Nickel Manganese Graphite Carbon Organic Electrolyte High Power Fortelion Cylindrical Iron Phosphate Graphite Carbon Organic Electrolyte High Power, Inherent Safety A-Series Laminated Cobalt Graphite Carbon Gel Polymer Flexible Size, Light and Small 5

6 Features of Lithium Ion Iron Phosphate batteries Feature Benefit Feature Benefit 1 Inherent safety Ideal for residential and commercial use 5 Outstanding performance at high temperatures Increased reliability under severe whether 2 Long cycle-life Best for PV applications 6 Deep discharge capability No system overdimensioning needed 3 Long calendar life No replacements during project duration 7 Iron used as cathode Environmental friendly, no rare metal disposal 4 High discharge power Best suited for back-up and hybrid applications 8 Quick charge Adaptability to fast changing energy sources 6

7 Inherent safety of Lithium Iron Phosphate comes from its robust chemical structure and high thermal stability Triphylite: LiFePO 4 (discharged condition) Lithium Iron Phosphate in the nature Heterosite: FePO 4 (charged condition) Lithium Iron Phosphate is a stable mineral since it exists in nature in both discharged and charged forms. Benefit Crystal structure of Lithium Iron Phosphate LiCoO2 Li Fe O P The oxygen and the phosphorus in the phosphate are strongly fixed by covalent bonds. LiFePO4 No release of oxygen when heated: temperature run-away reaction is not a concern for batteries based on Lithium Iron Phosphate 7

8 Long cycle life and deep discharge capabilities considerably improve the system s Total Cost of Ownership and greatly reduce the environmental impact Cell specifications Benefits 8000 cycles w/100% DoD 1 Sony LFP battery = 1,2 kwh (100% DoD, >8000 cycles) is approximately equivalent to 2 kwh any other Li-Ion chemestry (60% DoD, <6000 cycles) is approximately equivalent to Charge: 23 o C, 3.60V, 3.0A (CCCV), 100mA cut Discharge: 23 o C, 3A, 2.00V cut off 4 kwh Lead Acid battery (30% DoD, <3000 cycles) In 20 years you will No replacement needed for Sony LFP battery Probably 1 replacement needed for other Li-Ion batteries At least 2 replacements needed for Lead Acid batteries 8

9 Sony is worldwide one of the few experts in LFP material technology as well as a pioneer designing and building advanced Lithium-Ion batteries. Advantages Customer s benefits World-class own advanced LFP material technology State of the art Li-Ion battery design Best in class, environmental friendly battery designed for maximum performance and safety in renewable energy and back-up applications High quality Li-Ion battery mass production Energy Storage Module 9
