Introduction
Batteries are a great source of storing electrical energy, which is later converted into usable force. Many devices, such as laptops, electric vehicles, phones, and other useable devices, depend on batteries for energy needs. Moreover, batteries are not the same; they are divided into many types and vary in many ways, such as price, structure, and performance.
Battery technology has evolved through many stages and has been shaped according to the demands and needs of people. These demands have increased the types of batteries to fulfil the needs of growing sectors. If we talk about its type, we will see many categories in this technology, such as alkaline batteries, lithium-ion, and many others. Like all other inventions, it also has some pros and cons. Furthermore, we will also discuss its growing potential with pending challenges and possibilities in the existing environment. Lastly, we will unleash some facts about the growing battery technology and the possibilities it is creating in the transformation of the world.
Alkaline Batteries
This is one of the most used types of batteries, which does not need any charging. Its structure is simple. If we talk about its composition, it includes a zinc anode, a manganese dioxide cathode with an alkaline electrolyte known as potassium hydroxide. It has a minimal voltage of 1.5 V and runs high current for quite a long period. This attribute makes it desirable to use in children’s toys, clocks, or remote controls.
Moreover, if we talk about possibilities and opportunities, how can we not discuss some challenges it faces?
With all possibilities and revolutions that it is making, there come some limitations with it as well. If we compare alkaline batteries with other batteries, it will be known that they have low or minimum energy compared to other types. It also faces issues like self-discharge, low performance in low temperatures, and leakages. The most important thing is that if it is not disposed of properly, it can contribute to many health and environmental risks because it has many toxic chemicals. Some researchers have shown that in 2016 it contributed 17% of the global battery market, but it is anticipated to decline due to the increased demand. However, many innovators are working to increase their credibility and limit their risks.
Lithium-ion batteries
This type of battery is generally used on a large scale. Just like Alkaline, it is also rechargeable. Its mainly used for devices that demand high energy, in which electric vehicles, phones, and laptops are examples. Unlike Alkaline, it has not very simple structure because it consists of a graphite anode, metal oxide cathode, separator, and so on. Its voltage normally falls around 3.6 V and can produce high power for a long time. This makes it a high-level type of battery, among other batteries.
Like all other batteries, it also faces some limitations. It is quite costly compared to other batteries because of its short ingredients. Many safety concerns are also reserved regarding this type of battery, such as explosion due to the unreliability of some components. Similarly, in case of any carelessness in disposing of these batteries can impart harm and toxic materials, which can be harmful not only to human existence but also to the ecosystem. It can also increase some dreadful threats to the surrounding. In keeping with a report of 2019 by McKinsey, these batteries contribute around 85% of the global battery market. Like Alkaline, many researchers do their best to make it more reliable and credible. For instance, innovators have discovered that using new materials and up-to-date methods can increase the durability and efficiency of these batteries.
Metal-air batteries
These batteries are considered primary or secondary batteries, and their composition is mainly made of the metal anode of zinc, lithium, iron, or aluminium with an air cathode that absorbs oxygen. Like Alkaline, it also follows a simple structure comprising a metal anode and an air cathode.
Compared to other batteries, it has dense energy and high voltage. It also requires lightweight power sources like stationery power and military electronics.
Likewise, all the batteries mentioned above also have some challenges and restrictions. They have low power density and lower capacity compared to other batteries. These limitations are primarily due to slow kinetics and constraints on mass transport. Additionally, they face stability issues, including parasitic reactions of the metal anode, passivation, and cathode poisoning. Technical and operational threats, such as gas diffusion, electrolyte leakages, and sealing concerns, also need to be addressed.
According to a report by MarketsandMarkets, these types of batteries contributed to only 2% of the global battery market in 2019. However, with increasing demand, there is anticipated growth in their market share. In this regard, many researchers and innovators are actively working to make these batteries more durable, efficient, and safe. They have explored new catalysts, novel electrolytes, and hybrid systems to enhance performance.You can find additional information on battery safety precautions.
Other types of batteries
Many other types of batteries have distinct features, pros, and cons. To name some of the examples are lead acid, nickel-metal hydride, and many others. These batteries differ in their structure and performance from each other.
- One of the oldest batteries is lead acid batteries which are also rechargeable. It has low cost but high power and is mainly used in cars and bikes. They also follow a simple structure.
- Another type is Nickle -metal hydride batteries, which are also rechargeable. Its voltage is around 1.2 V per cell, and has double capacity. They are mainly used for moderate power. It’s very costly and performs badly at low temperatures.
- Sodium-sulfur batteries are high in temperature that use sodium metal as the anode. If we talk about its voltage, it is 2 V per cell and rich in dense energy. Its efficiency makes it desirable to use for large-scale energy shortages. It faces some limitations, such as high operating temperature and safety threats due to explosion and reaction o sodium and sulfur. Due to deterioration in composition, it can have a limited life cycle.
Some potential applications and further prospects of these types of batteries are:
- Lead acid batteries are mostly used in automotive firm because it is not costly but dependable and durable.
- Nickel-metal hydride batteries are competitors of lithium-ion batteries because of their low performance and high cost.
- Sodium-sulfur battery usage is largely seen in stationary energy due to its dense energy and durability.
