scope of metal-air batteries.
Restraints in
Metal-air Battery Market
Lack of proper standards for developing metal-air batteries
A major challenge faced by market players in the metal-air
battery industry is the absence of standardized development guidelines.
Different companies manufacture batteries with varying technical
specifications, materials, and functional designs, making it difficult to
compare their performance. This highlights the need for concrete standards that
can measure the performance of metal-air batteries based on their design.
Moreover, metal-air batteries designed for specific applications differ in
function, size, property, and structure. For example, batteries used for
grid-scale applications may differ from those used in residential settings.
These customized battery systems cater to the specific requirements of
end-users, which may also result in variations in cost. Consequently,
off-the-shelf metal-air batteries available in the market may not align with
the specific needs of similar applications.
Opportunities in
Metal-air Battery Market
The emerging application areas for metal-air batteries,
apart from electric vehicles, present significant opportunities for the IoT
market during the forecast period. These high-energy density batteries offer
scalable, cost-effective, and high-capacity designs that cater to a wide range
of IoT applications. Companies in this market are actively developing metal-air
batteries that meet or exceed the quality of existing battery products for IoT
applications. Additionally, there is a growing need for advanced battery
technologies in electric grid storage applications due to supportive government
policies and the shift of utility providers towards renewable energy sources.
While zinc-air batteries have traditionally been used in non-rechargeable small
devices like hearing aids, the potential of metal-air batteries lies in their
higher energy densities compared to conventional lithium-ion batteries. This
increased energy density can result in longer-lasting battery life and extended
driving ranges for electric vehicles, making them more viable and competitive.
Moreover, metal-air batteries, such as zinc-air batteries, leverage oxygen from
the air as the cathode, reducing the reliance on heavy metals and hazardous
materials. This makes them potentially more environmentally friendly and
sustainable compared to conventional battery chemistries. Metal-air batteries
can also play a vital role in integrating renewable energy sources into the
electrical grid by offering high energy density and long-duration capabilities.
They can store excess energy generated from sources like wind and solar during
low-demand periods and release it during high-demand periods, thus enhancing
grid reliability and efficiency. The application of metal-air batteries,
particularly lithium-air batteries, holds promise in revolutionizing electric
vehicle technology by addressing the limited driving range challenge. With their
high energy density, these batteries can enable longer-range electric vehicles,
accelerating the adoption of clean transportation and reducing reliance on
fossil fuels. As the global demand for energy storage solutions grows, emerging
markets in regions like Asia, Africa, and South America present significant
opportunities for metal-air batteries, especially as these regions actively
invest in renewable energy and seek efficient and sustainable energy storage
solutions.
Challenges in
Metal-air Battery Market
One of the notable challenges faced by zinc-air batteries,
which are among the most mature metal-air batteries, is the corrosion that
occurs between the electrolyte and the anode. This corrosion reaction can
generate explosive hydrogen gas, posing safety risks. However, ongoing research
has shown that incorporating zinc alloys with lead, mercury, cadmium, and lead
oxides can mitigate the formation of hydrogen gas, reducing the associated
risks. This challenge of corrosion and hydrogen gas formation needs to be
effectively addressed to enhance the safety and reliability of zinc-air
batteries for larger-scale applications.
Ecosystem of Metal-air Battery Market
The zinc segment held the largest market share in the
previous year, primarily due to the remarkable shelf life of sealed zinc-air
batteries. These batteries exhibit higher energy storage capacity per unit
weight compared to other primary battery types. Zinc-air batteries offer the
advantage of low cost and high safety, thanks to the productive electrode
characteristics of zinc. They are available in various sizes, ranging from coin
cells to button cells, commonly used in electronic devices such as watches and
hearing aids. Larger zinc-air batteries find applications in cylindrical or
prismatic cells for railway remote signaling. The zinc segment is anticipated
to continue its dominance in the metal-air battery market during the forecast
period.
Aluminum-air batteries, which utilize atmospheric oxygen as
a cathode and aluminum as an anode in an electrolyte solution, are known for
their exceptionally high energy density. These batteries hold the potential to
significantly enhance the range of electric vehicles compared to lithium-ion
batteries, while also reducing overall weight. The utilization of aluminum-air
batteries not only offers environmental benefits but also capitalizes on the
ready availability of aluminum. These factors are projected to be major driving
forces for the growth of the metal-air battery market in the forecasted period.
In terms of voltage, the low voltage segment emerged as the
largest market segment in the previous year. The demand for low-voltage power
is fueled by changing lifestyles, increasing disposable income, and the rising
