The global battery market is a powerhouse, currently valued at approximately $55 billion, with around $6 billion specifically attributed to rechargeable batteries. Projections indicate a steady growth rate of 5% annually through 2012. Emerging economies like Indonesia, Pakistan, Ecuador, Germany, and Japan are poised to experience significant market expansion.
The automotive sector is a key driver, exhibiting strong double-digit growth. Hybrid Electric Vehicles (HEVs) fuel the demand for lithium and related technologies. The traditional Sealed Lead-Acid (SLA) battery market maintains robust revenues due to aftermarket sales and the growing number of vehicles worldwide. Replacement sales account for almost half of the $13 billion lead-acid battery market. Despite fluctuations in lead prices, SLA batteries are expected to sustain their growth due to their reliability, durability, cost-effectiveness, and the absence of a universally superior replacement.
The PC battery segment is another area of significant growth. It is projected to increase from $1.5 billion in 2006 at an approximate compound annual growth rate of 8%.
These market dynamics underscore the immense potential within the battery industry, attracting substantial venture capital investment. A breakthrough in battery technology could yield significant returns, given the pervasive reliance on batteries for portable devices.
The lithium rechargeable battery market is forecast to reach $7 billion by 2015. Within this segment, the market for lithium rechargeable batteries in Hybrid Electric Vehicles is projected to surge from near zero in 2006 to approximately $2 billion in 2015, reflecting an impressive 50% year-over-year CAGR. While the overall demand for lithium batteries is increasing rapidly, revenue growth is tempered by decreasing device costs resulting from manufacturing efficiencies and increased production volumes.
The battery market is characterized by intense competition and substantial investment in research and development. Advancements in both established and novel chemical technologies are expected to yield improvements in battery capacity (for a given size and weight) by a factor of 3 to 4 within the next four years. This doubling of capacity every two years mirrors Moore’s Law in the computer industry.
Consumers typically purchase single-use batteries four times per year. These batteries often generate the highest profit margins per square foot in retail stores and are frequently impulse buys. They are sold in more retail outlets than any other product due to the widespread dependence on batteries. Sales are generally considered resilient to economic downturns.
However, disposable batteries pose environmental challenges. Landfills are accumulating toxic byproducts from their use. The European Union has addressed this issue through the European Directive on Batteries, implemented in 2008, which mandates recycling. It is hoped that the United States and other countries will adopt similar environmental regulations.
