Sodium-ion	100-150	50-100	1500-2000
Flow Battery	50-80	150-250	5000+

The table above provides a simplified comparison of key battery technologies. It’s important to note that these figures are constantly evolving as research and development progress. The 'projected' values indicate expectations for future performance as the technologies mature.

Investment Vehicles in the Battery Sector

Investing in the ‘battery bet’ isn't limited to direct investment in battery manufacturers. A wide range of investment vehicles are available, catering to different risk appetites and investment horizons. These include publicly traded battery companies, exchange-traded funds (ETFs) focused on the battery supply chain, venture capital funds specializing in early-stage battery technology, and private equity investments in established battery businesses. Each approach has its advantages and disadvantages. Direct investment in companies offers the potential for high returns, but also carries significant risk. ETFs provide diversification, but may offer lower potential returns. Venture capital and private equity typically require larger investments and longer time horizons.

Analyzing Battery Supply Chain Investments

A particularly interesting investment strategy focuses on the entire battery supply chain, rather than just the battery manufacturers themselves.
