A battery bet isn’t solely about the companies making the batteries themselves. A robust and resilient supply chain is equally crucial. This includes the mining and processing of raw materials, the manufacturing of battery components (electrodes, electrolytes, separators), and the assembly of battery packs. Investing in companies across this value chain can diversify risk and capture value from multiple segments of the market. Vertical integration – where a company controls multiple stages of the supply chain – can also provide a competitive advantage, but requires significant capital investment and expertise.

Geopolitical considerations play a significant role in supply chain dynamics. The concentration of raw material processing in certain countries creates potential vulnerabilities. Diversifying sourcing and developing domestic processing capabilities are strategic priorities for many governments and companies. Investments in companies focused on sustainable and responsible sourcing of battery materials are increasingly attractive to investors.

The Importance of Battery Management Systems (BMS)

Effective battery management systems are essential for optimizing battery performance, ensuring safety, and extending lifespan. A BMS monitors critical parameters such as voltage, current, temperature, and state of charge, and regulates battery operation accordingly.
