3 Technological Trends for the Next Decade Energy Demand The need for portable energy sources is the main driving force behind energy density improvements in electro-chemical power sources. Lithium Ion Technology Used in new applications especially with large batteries/cells in place of other technologies. The energy density gap to primary technology will be decreased. 3

4 Technological Trends for the Next Decade New chemistries? Probably no new chemistry. New types of Li-ion rechargeable cells will be developed with better performance and there will be small energy density improvements in primary cells. Small portable fuel cells? Will find a place in niche markets, mainly in expensive applications, and, if there is going to be cost reduction, in military application and portable commercial electronic devices. 4

5 Technological Trends for the Next Decade Hybrid systems? Increase in hybrid systems, how to integrate the good performance of different energy sources like battery + capacitor, battery + fuel cell, primary cell + rechargeable cell, etc. 5

6 Energy Demands in the Next Decade More Batteries Increased demand for hybrid & EV, electric scooters and electric bikes as a result of high gasoline costs and the need for a "Green" environment. Vectrix scooter Hybrid car Electric Bike

7 Plug-In Hybrid Cars P.H.E.V. Hybrid with larger batteries, with an extension cord for battery charging & a backup gas tank. Cleaner, cheaper, quieter car for local travel. Gas tank is always there should you need to drive longer distances If your driving is mostly local, you'd almost never need to gas-up. Will fill the gap until EV batteries with better performance will be developed. 7

8 Plug-In Hybrid Cars P.H.E.V Current HEV cars uses NiMh batteries. Li-ion with better energy density per weight, higher 100% D.O.D cycles & fast charge are vital. PIHEV will start using Li-Ion batteries during Car Manufacturers decided to manufacture Li-Ion batteries in their own plants (Toyota, Nissan, GM, Ford). 8 The Toyota Vitz has a Li-Ion for start-stop

9 Energy Demands in the Next Decade More Batteries Increase demand for portable more Laptops, PDAs, Cellular phones, Video cameras, Games, Power tools & integrated applications like PDA with integrated Cellular phone & GPS. 9

10 Energy Demands in the Next Decade Portable market uses all 4 technologies: Ni-Cd, Ni- Mh, LIB, LIP. Expectations for the coming years are that Li-Ion will increase market share at the expense of the nickel chemistries, except in the consumer market. Consumer market will use mainly AA, AAA Ni-Mh cells. 10

11 Energy Demands in the Next Decade Current UPS & energy storage systems use leadacid batteries. In Mid future starting at 2012 these systems will move to Li-Ion batteries. 11

12 Why Li-Ion is the Leading Rechargeable Chemistry? Highest energy densities excellent choice for portables & stationary applications. World Li-Ion battery production increases yearly, especially in China that leads to a cost reduction & chemistry penetration to new markets. 12

13 Why Li-Ion is the Leading Rechargeable Chemistry? Better protection of electronics, resulting in reduced costs, increased safety & optimized energy. New High Power Lithium Iron Phosphate battery versions close the gap towered other classic rechargeable high power chemistries. 13

14 The Current Gap, Li-Ion vs. Primary LITHIUM SULFURYL CHLORIDE ELECTROCHEM 3B30 C - SIZE LITHIUM ION PANASONIC NCR18650 A LONG A SIZE 7 AH 3.1 AH 444 WH/KG 257 WH/KG 927 WH/L 647 WH/L 14

16 Li-Ion Chemistry Future Developments New anode materials like Nanostructure metallic alloy instead of carbon material (graphite carbon) will increase energy density up to 30%. Sony s new technology "NEXLION" offers 15% more energy density with fast charge but low cycle life (reduction from 600 to 300 cycles). 16

17 Li-Ion Chemistry Future Developments New Matsushita Li-Ion cells offer 20-40% more capacity (18650 cell with 3.6AH capacity, 2v C.O.V) using a novel material for use in the electrode. PRESENTED at the 2007 International CES/ Las- Vegas. General near future expectation for 20-40% energy improvements 17

18 The Vision - Performance Without Decreasing Safety Sony LIB safety problems lead to painful damage to the company studied seriously by the world battery industry Safety! Safety! Safety! According to Sony, at the packing phase during the manufacturing process, particles of Cu, Al, Fe & Ni get mixed in and generate a possible internal short circuit. 18

19 Matsushita (Panasonic) HRL New Li-Ion Safety Technology MBI has succeeded in improving the safety by forming a heat resistance layer (HRL). Lithium-Ion batteries contain a thin polyolefin*2 separator to insulate the cathode from the anode. 19

20 Matsushita (Panasonic) HRL New Li-Ion Safety Technology When a separator is pierced by an electrically conductive material such as a metal particle, a short-circuit develops, causing the battery to overheat and, in the worst case, catch fire. The HRL has better insulating & heat-resistant characteristics than polyolefin. Even if a shortcircuit occurs, it will cease without causing the battery to overheat. 20

21 LIP Replacement Technology for LIB Improving Li-Ion energy densities lead to more safety risks like vents, explosion & fires. LIP considered safer: - It contains no flammable liquids - Lithium as an active ingredient - Smaller capacities - Larger foot print better heat dissipation. LIP safer No internal safety elements. LIB less safer Vents, PTC, circuit breaker. 21

22 LIP - Replacement Technology for LIB Current LIP battery world production, including China, is increasing fast and soon will be higher than LIB. LIP will replace LIB in the long term as a result of many safety incidents that have occurred in the last number of years. 22
