The 21st century is the period when history itself is in for an eventful change. We have never been as dependent on reliable and sustainable sources of power, because of electronics being our everyday life and the electric vehicle industry growing. At the core of this electric turning of the century is a piece of technology that is hardly ever recognized - the battery. 

From Alessandro Volta's primitive voltaic pile in 1800 to the sophisticated batteries of today, batteries have come a long way. Today, we are at the brink of a new epoch – the Age of Battery. This blog is going deep into the topic of this interesting field, including the major players, new contenders and the key function battery recycling will play in the green future - with the help of recent data and analytics. 

Lithium-Ion: The Current King, But Facing Scrutiny 

Lithium-ion (Li-ion) batteries currently hold the number one spot in the portable electronics market, and it powers everything from laptops and tablets to wireless headphones and cameras. In 2023 alone this market share makes up 46%, according to SkyQuest’s Lithium-ion (Li-ion) battery market . Their high specific energy (typically ranging from 150-300 Wh/kg) and continuous discharge characteristics for longer duration with the ability to recharge make them the best for our lives-on-the-go. 

Safety Concerns: Following the negative experience of previous thermal runaway cases involving Li-ion batteries, particularly dynamic situations like electric vehicles, the issue still poses challenges. In 2022, the National Highway Traffic Safety Administration (NHTSA) in the US released a report saying that over 300 vehicle fires from 2010 to 2022 were called into question and blamed on lithium-ion batteries. 

Ethical Sourcing: The mining activity to obtain these precious raw materials including lithium and cobalt might face ethical implications because of environmental impact and human rights abuse concerns in mining areas. In a 2023 report, Amnesty International shed the light on child labor in cobalt mines in Democratic Republic of Congo where children experience extreme labour condition. 

Limited Lifespan: The lifespan of Lithium-ion batteries is finite and undergoes a gradual degradation in capacity over time that results in their replacement of electronic waste (e-waste). The United Nations estimates that global e-waste generation reached a staggering 57.4 million metric tons in 2021. 

Beyond Lithium: A Spectrum of Battery Technologies 

Sodium-Ion Batteries:  Sodium-ion (Na-ion) batteries have a direct competition edge because sodium is inexpensive and available in abundance as compared to lithium. Sodium is estimated to be 1,000 times more common than lithium in the Earth's crust, thus, the Na-ion batteries may provide a more environment-friendly solution to society. Starting the year of 2023, a team of researchers from the University of California, San Diego, has unveiled a model of new Na-ion battery which outperforms current systems not only in terms of energy density, but also in their environment-friendliness and availability. The analysts at IDTechEx predict the total sum of the global Na-ion battery market by 2028 to be USD 5.2 billion. With large-scale energy storage application expected to be worth $42.3 Billion (about $130 per person in the US) by 2027 according to Grand View Research, Na-ion battery will gain its major foothold specifically in the large-scale environment including cost-effectiveness and safety.

Lead-Acid: The Old Guard Still Packs a Punch 

Li-ion on the contrary rules the portable electronics market, but lead-acid battery is still the main battery for automotive applications. Underscoring their superiority and affordability, they have become the first choice for new ICE engine cars. 

The Recycling Champion: Lead-acid batteries have a very recyclability of about 90% in developed countries. With their pledge to sustainability, they are therefore the ethical choice for the environment. 

Advanced Valve Regulated Lead Acid (AGM): This feature of the lead-acid battery has superiority and spill-proof characteristics which makes it suitable for motorcycles and power sports vehicles. 

Evolving Role in Hybrid and Electric Vehicles: Although lithium-ion (Li-ion) is the best choice for electric vehicles (EVs), it does not yet replace the primary function of lead-acid batteries. Usually, they are employed to drive auxiliary systems, allowing for longer distances and better efficiencies. 

 
Nickel Metal Hydride (NiMH): A Niche Player Endures 

Some years ago, Ni-MH was the best alternative to rechargeable Ni-Cad batteries. They are larger and last longer than Ni-Cad, however, the fact that Li-ion is dominant in the niche market makes it hard for them to be in the main market. Here's where NiMH batteries find favor: 

Environmental Benefits: NiMH batteries are devoid of toxic substances (e.g., mercury and cadmium) and hence are a more reliable alternative in terms of the environment. 

Lower Self-Discharge: In comparison with Ni-Cad batteries, NiMH batteries are characterized by a considerably lower rate of self-discharge. Thus, they can retain their charge even for several months after their last use. 

Ideal for Specific Applications: They are also unsuitable for handheld devices (smartphones) as they have a low energy density. However, they can be an option for devices that have high energy demands like digital cameras and power tools. 

The Booming Battery Recycling Market 

With the increasing extent of our reliance on batteries, the need to implement eco-friendly recycling methods also increases. Recycling of batteries includes valuable materials such as lithium, cobalt, and nickel out of spent batteries increases independence from virgin resources, decreasing the environmental impact.

A Well-Charged Future 

The Battery Age is already here, and innovation is the buzzword. Lithium-ion batteries will be the principal type of batteries soon, but sodium-ion, NiMH and other new technologies that will come to the market open a lot of opportunities. With a sustainable future in mind, the emphasis will not only be on increasing energy density and efficiency but also on good sourcing practices, ethical manufacturing and robust recycling strategies. 

Batteries have a great future ahead. Continued research and development make us hope for a future when batteries are more powerful and long-lasting and provide us with peace of mind knowing that they are also environmentally friendly. This will mark the beginning of the 'real' adoption of electric systems founded on clean energy and green approaches.
