IDTechEx reports that the electrification of the construction, agriculture, and mining industries is accelerating, with the construction sector already offering numerous electric machines, while agriculture and mining are set to follow. This transition presents significant opportunities for cell manufacturers and battery pack producers, with battery demand across all CAM industries expected to reach 53.6 GWh by 2034. The industry’s value is projected at US$7.8 billion by that time, with a compound annual growth rate of 27.1 percent over the next decade.
Electrifying CAM machinery requires a diverse range of battery sizes, from 10 kWh to 2 MWh, as well as performance attributes focused on cost, safety, and longevity rather than energy density, which is critical for passenger electric vehicles. Many CAM machines, such as heavy equipment, prioritise balance and stability, meaning energy density is less of a concern. IDTechEx’s report explores how existing and emerging battery technologies can meet the specific needs of the CAM sectors.
The CAM battery market is dominated by nickel manganese cobalt and lithium iron phosphate (LFP) chemistries, which are widely used by manufacturers such as Forsee, Accelera, and CATL. These technologies offer energy densities ranging from 100-200 Wh/kg and cycle lives that meet the demands of most CAM applications. NMC batteries, with their higher volumetric energy density, are better suited for smaller machines like excavators, where space is a premium. In contrast, LFP is more cost-effective and typically used in larger machines where weight is less of a concern. IDTechEx’s research shows that geography and regional supply chains can also influence the choice between NMC and LFP.
In addition to NMC and LFP, IDTechEx analyses the potential of emerging battery technologies such as lithium titanate and silicon anode cells. LTO, while offering lower energy density, excels in high cycle life and fast charging. Haul trucks, which require minimal downtime and a long operational lifespan, are identified as prime candidates for LTO batteries due to their ability to charge in just minutes and sustain up to 40,000 cycles.
Silicon anode cells offer high energy density, making them promising for sectors like agriculture, where machines may only operate for a few weeks each year, thereby benefiting from fewer charge cycles. However, challenges related to silicon’s longevity need to be addressed, as its repeated swelling during charge cycles can limit the battery’s lifespan.
IDTechEx’s report covers a database of over 200 electric CAM machines and nearly 200 battery products from leading suppliers. It provides detailed forecasts for battery demand and market size over the next 10 years, evaluating 15 machine types and 10 battery technologies, including solid-state batteries, sodium-ion, and lithium-metal solutions. The report also benchmarks off-the-shelf battery products, offering critical insights into vehicle trends, performance analysis, and future market growth.
This analysis positions electrification as a key driver for innovation in the CAM industries, with tailored battery solutions leading the way toward a sustainable future.
