Companies must align their strategy as a result of the significant changes brought about by the COVID-19 pandemic in the supply chain for 21700 Lithium-Ion Batteries and the growing movement to switch to cleaner, more dependable, and greener energy sources. Furthermore, the need for 21700 Lithium-Ion Battery sector players to be more watchful and forward-thinking is pressing due to worries about the slowing of the world economy, the effects of the war in Ukraine, and the risks of stagflation with potential market scenarios. Manufacturers of 21700 Lithium-Ion Batteries and related stakeholders are developing country-specific strategies as a result of the economic and social effects of COVID being found to vary greatly between different countries/markets. An impressive growth rate is expected in 2021 as a result of the post-pandemic economic rebound driving up energy consumption, automotive, industrial, and consumer goods sales.

LATEST TRENDS

Increase in battery recycling activities leading market expansion

The key trend influencing the market growth for 21700 lithium-ion batteries is an increase in battery recycling activities. In many electronic gadgets found in electric cars, forklifts, and other material-handling machinery, batteries are used. The quantity of batteries that approach their end of life will climb as their use spreads across more applications. For instance, the Australian Battery Recycling Initiative (ABRI), a non-profit organisation, was founded in 2008 to advocate for the ethical management of batteries' environmental impact when they reach the end of their useful lives.

The increase in demand for laptops, tablets, and other consumer electronics due to the trend towards remote work and increased reliance on digital devices opened up opportunities for the lithium-ion battery business. Additionally, government stimulus plans and programmes supporting renewable energy and electric mobility gave the sector a boost. At some point during the epidemic, the need for large-scale batteries and other power storage solutions started to become apparent, which also fueled the need for lithium-ion batteries. 

• According to the Australian Battery Recycling Initiative (ABRI), over 50,000 lithium-ion batteries were collected for recycling in 2024, reflecting increased environmental responsibility and market expansion in battery lifecycle management.

• According to the U.S. Department of Energy (DOE), demand for lithium-ion batteries in consumer electronics, including laptops and tablets, has grown to over 200 million units annually, driven by remote work and digital device adoption.

DRIVING FACTORS

Better capacity and performance may drive the market growth

The main driver propelling the growth of the 21700 lithium-ion battery market is better capacity and performance of lithium-ion batteries.  One of the main areas of focus for research and development in the EV sector continues to be battery packs, which make up a significant portion of the entire cost structure for EV manufacturers and determine the performance of any EV. However, due to its resemblance with the more seasoned 18650 lithium-ion batteries in terms of the production process, technical procedure, and raw material selection, the adoption of 21700 lithium-ion batteries in the EV sector continues to expand. Due to the benefits of 21700 lithium-ion batteries, EV manufacturers are increasingly pursuing high-specific energy battery systems, which is propelling the 18650 and 21700 battery market growth.

Proliferation of demand for smart storage may drive the market growth

Demand from emerging markets is predicted to drive the 21700 Lithium-Ion Battery Market Revenue to rise at a strong CAGR. The 21700 Lithium-Ion Battery market is benefiting from developments in digital technologies that allow for more effective production, portfolio expansion, operational maintenance, and sales tracking. Increasing disposable incomes in developing countries that are developing quickly, decentralised networks, intelligent automation, and a proliferation of demand for smart storage are a few of the important market developments.

• According to the U.S. Department of Energy (DOE), electric vehicles in the U.S. now exceed 2.3 million units, driving demand for 18650 and 21700 lithium-ion batteries with higher capacity and performance.

• According to the International Energy Agency (IEA), global renewable energy storage systems deployed over 45 GWh of lithium-ion battery capacity in 2024, creating strong demand for advanced battery technologies.

RESTRAINING FACTORS

Battery safety issues may restrict the market growth

Lithium-ion battery safety issues are a significant barrier to the market's expansion for 21700 lithium-ion batteries. The most popular battery type for EV propulsion has emerged as lithium-ion batteries. However, flammable materials are only utilised as an electrolyte in lithium-ion batteries, which are the only widely used batteries. In lithium-ion batteries, electrolytes act as catalysts to prevent the direct exposure of lithium to moist air, which could cause it to catch fire or explode.

The phenomena of thermal runaway, in which a battery's temperature increases to the point at which it catches fire or explodes, is also prone to occur with lithium-ion batteries. The 21700 Lithium-Ion Battery market will be constrained over the forecast period by factors such as adherence to strict regulations and disparate standards around the world, growing competition, inflation estimated to stay above the upper band during the short term in key nations, and fluctuating raw material prices. The high cost of EVs and poor battery performance are the main impediments to their widespread adoption.

• According to the European Chemicals Agency (ECHA), over 15 regulatory standards govern the production and disposal of lithium-ion batteries in Europe, increasing compliance challenges.

• According to the U.S. Environmental Protection Agency (EPA), lithium-ion battery manufacturing contributes to around 12% of industrial chemical waste per facility, limiting rapid expansion due to environmental concerns.
