Assignment # 2 - Case Study-compressed

Transition Away from Fossil Fuels: The 2020s mark a significant shift in economic history as global demand for oil declines in favor of electricity from renewable sources.
Central Role of Batteries: As the world shifts towards a low-carbon future, batteries—especially lithium-ion batteries (LIBs)—will play a crucial role in this new economy.
Historical Context: Batteries have been used since the late 19th century, but the 20th-century development of alkaline and LIB technologies has enabled portable electronic products.
Rise due to Electric Vehicles (EVs): The anticipation of the decline of the internal combustion engine has led to optimism from battery producers, with electric vehicles taking center stage.

Growth of EV Models: In 2020 alone, over 50 new electric vehicle models were launched with 80 more expected in the coming years.
Tesla's Gigafactory: Opened in January 2017, Tesla's Nevada Gigafactory began producing LIBs, spurring investment in production plants primarily in China.
Government Policies: Various countries are phasing out petroleum-fueled vehicle sales, assuring significant growth in LIB demand, which has led auto manufacturers to invest in LIB production.
Profitability Challenges: As of 2019-2020, leading manufacturers had net margins ranging from 2.5% to 10.6%, with some even incurring losses, leading to uncertainty about future profitability despite rising demand.

Historical Development: Research began in 1912, but commercially viable LIBs only emerged in the 1970s. Sony’s introduction of rechargeable LIBs in 1991 established dominance in mobile electronic devices.
Advantages of LIBs:
- Lightest metal with excellent energy density (twice that of nickel-cadmium batteries).
- High cell voltage of 3.6 volts, allowing for single-cell battery packs.
- Low maintenance with low self-discharge rates and long recharge cycles (over 1000 cycles).
- Safe disposal options compared to alternatives.
Safety Concerns: While lithium compounds used in batteries are safer, incidents of spontaneous combustion have highlighted safety risks, as seen with incidents involving Sony, Boeing, and Samsung.

Standard Cell Design: The 18650 cylindrical cell is standard for electronic devices, while automotive manufacturers seek larger cells like Tesla's 21700 and newly announced 48600 to reduce battery pack size.
Improvements in Technology: Continuous enhancements aim to increase energy density, often achieving around 5% improvement annually, though some may compromise other performance metrics.
Alternatives and Substitutes: Development efforts focus on replacing high-cost materials like cobalt and finding more abundant substitutes for battery components, which can affect the cost and availability.

Shift to Electric Vehicles: By 2020, EVs accounted for 76% of LIB consumption, reflecting their capacity—Tesla’s 85 kWh battery comprises 7104 cells.
Future Demand Forecasts: Between 2021 and 2030, demand for LIBs is expected to surge, driven by governmental targets to phase out gasoline vehicles. Global EV sales predictions for 2030 fluctuate between 14.1 million and 31.1 million.
- Forecast Sensitivity: Forecasts are sensitive to consumer adoption of EVs; production per year around 100 million vehicles has potential battery needs ranging from 750 GWh to 1500 GWh depending on EV market share.

Global Manufacturing Landscape: The supply of LIBs is primarily dominated by East Asian companies, with companies like Panasonic and LG Chem leading their fields.
Investment Influences: Investment in new production capacities is guided by government subsidies and policies, especially in China.
Resource Availability: A growing concern lies in the supply of key raw materials like lithium and cobalt, posing risks to production continuity and cost stability.
- Lithium Production: Concentrated mining and production exist in regions like Australia and Chile, with significant reserves and quality constraints.
- Cobalt Availability: Cobalt supply is significantly reliant on the Democratic Republic of Congo, facing ethical, logistical, and production challenges.

Technological Competition: Efforts toward a carbon-free future may create competition with alternative technologies like fuel cells or other energy storage solutions.
Promise of New Technologies: Although LIB technology dominates the current landscape, emerging technologies (e.g., magnesium-ion, lithium-sulfur, solid-state) may offer potential alternatives, although none have yet commercialized as of 2021.
