To develop, manufacture, market and support the sale of lithium compounds for future applications, the resources of a global, well-established, specialty chemicals company are essential. Lithium Business

Lithium compounds will experience significant growth due to the introduction of all electric and plug-in hybrid electric vehicles. WHY?

National security and economic stability concerns will force us to eliminate our dependence on imported oil.

Freedom from imported oil can only be achieved if we start driving electric cars on a massive scale. The best source of power for electric cars is lithium ion batteries.

Lithium, the essential chemical element in lithium ion batteries, can experience substantial growth.

Top World Oil Consumers - 2008 Source: BP, plc US

The United States of America depends heavily on imported oil from hostile regions of the world. 50% of our oil use is imported.

These hostile states, insurgents and terrorists will use oil as a strategic weapon against the United States.

This dangerous dependence on imported oil has created significant issues of: National Security Economic Stability

Dependence on imported oil, mostly from hostile regions, has constrained the totality of US foreign policy. To ensure free flow of oil, the US military has to maintain a presence in these hostile regions, at a huge cost in treasure and blood. Total cost of US military presence in these regions is estimated to be $5.0 trillion since the 1970’s. Issues of National Security

The cost of imported oil is more than $400 billion a year which is enriching the sovereign funds of mostly hostile regimes. This is more than half of the total US trade deficit. Issue of Economic Security

 HOUSEHOLD GASOLINE EXPENDITURES (ANNUAL, NOMINAL) US Oil Dependence: Economic Costs $ Source: Department of Energy, SAFE Analysis

70% of oil consumed in the US is to fuel our transportation system (the internal combustion engine). Renewable sources of energy, such as solar, wind or nuclear will not free us from imported oil. Oil Dependence

As long as our cars are powered by the internal combustion engine, we will be dependent on imported oil. The Problem: Oil Dependence

The only practical and proven solution is to replace the internal combustion engine with an electric motor driven by a rechargeable battery. The Solution: Electric Cars

Electrification of Transportation ELECTRIFICATION ARCHITECTURE

1. Electricity is diverse and domestic. Benefits of Electric Cars

2. Electric Power Sector: Generation Benefits of Electric Cars Source: Pacific Northwest National Laboratory LOAD SHAPE FOR ONE DAY DURING PEAK SEASON The electric power sector has substantial spare capacity at night that could be used to fuel electric vehicles.

3. The network of infrastructure already exists. Benefits of Electric Cars

4. Electric miles are cheaper than gasoline miles: 2.5¢ vs 10¢ per mile. Benefits of Electric Cars Source: SAFE Analysis

5. Electric miles are cleaner than gasoline. Benefits of Electric Cars

Key Enabling Technology – Li-ion Batteries:

Lithium ion batteries for mobile phones, laptops, portable electronics and power tools are fully developed and commercialized. This is Proven Technology

Lithium Ion Batteries

Depending on your assumptions of the penetration of all electric and hybrid electric cars in the coming years, the growth in demand for lithium can be substantially higher than the historical growth rate of 10% per year. Lithium Demand
