Lithium battery

Batteries with lithium as an anode are called lithium batteries. The charge moves from anode to cathode during discharging and from cathode to anode during charging. Lithium batteries were introduced as early as the 1980s to 1990s. These batteries have completely revolutionized the market for portable electronics such as cell phones and laptops.

What is lithium battery?


Was ist Lithiumbatterie?

Nowadays, lithium batteries are finding increasing use in electronics, electric cars, and solar markets. Because of their light weight, high energy density, and efficiency, lithium batteries are used in a wide variety of portable consumer electronics, medical devices, power backups, solar storage, and electric vehicles.

How is lithium battery different from lead-acid battery?

Wie unterscheidet sich Lithium-Batterie von Blei-Säure-Batterie?

Lead-acid batteries use plates made of lead and lead oxide in a sulfuric acid solution. These batteries are widely used in automobiles and trucks and are also rechargeable. Lead-acid batteries are cheaper but have a shorter lifespan and require regular maintenance. Lithium batteries are much more expensive upfront, but they are maintenance-free and have a longer lifespan. The leading popularity of lead-acid batteries is due to the fact that they are not only reliable but also very affordable. However, this technology is old, and technicians prefer lithium batteries to better serve the purpose due to their higher efficiency and density. Compared to lead-acid batteries, lithium batteries are more efficient and charge faster.

What are lithium batteries used for?

Wofür werden Lithium-Batterien benötigt?

As already mentioned, lithium batteries are increasingly being used in new technologies. Solar is already cheaper than coal and this trend will only accelerate. The biggest problem with solar systems, however, is that they rely on the power grid to store excess electricity during the day and draw electricity from the grid at night. This happens because the power grid acts as a free energy store for the solar panel systems. However, the industry quickly realized that this was not a viable option in the long run, given that utilities are the main competitors for solar energy. Hence, they began to use a self-sufficient storage option to support the proper functioning of the solar system.

Solar energy plus storage have already gained in importance as economic efficiency drives the faster introduction of solar systems in combination with lithium batteries. These batteries can be used in a variety of ways and, in addition to storing energy for the house, can also be used in energy wholesaling for capacity and frequency control. Lithium battery solar plus storage options are also seen as a serious option for islands as they find it cheaper to use solar plus storage rather than transporting expensive and dirty oil / diesel to power their residents. The remote areas where power is not available such as rural areas, hill stations, small shops, etc. will benefit greatly from these lithium batteries.

Advantage of the lithium battery over existing technologies

1. Logistics


The main advantages of lithium batteries are portability, which means we can take them with us wherever we need them. We never think about battery acid overflow. The weight of a lithium battery is 1/4 that of the lead-acid battery.

2. Fast charging – charges within 2 hours.

Schnelles Aufladen – Aufladen innerhalb von 2 Stunden

Lithium batteries charge and recharge much faster than lead-acid batteries. The experience of solar experts is that lithium batteries   can be charged within 2 hours , while lead-acid batteries take  almost 10 hours  to charge a full battery. We know that incoming mobile batteries charge in a short amount of time and provide an all-day backup.

3. Maintenance free

Lithium batteries do not require maintenance to ensure their performance. Only a few other types of batteries, such as nickel-cadmium cells, need to be discharged to prevent the memory effect. Lithium batteries, on the other hand, have no memory effect, which means that they do not have to be fully discharged before charging.

4. High efficiency

Hohe Effizienz

Lithium batteries provide reliable, stable, and long-lasting performance. Their energy density is higher, which means that they have high power capacity. This high energy density enables use in devices with high power requirements such as laptops and cell phones.

5. Cycle Life – More than 2000 times

Zyklusleben - Mehr als 2000 Mal

These batteries have an average life of over ten years. They can also handle more than 2000 charge-discharge cycles.

Lithium batteries are generally smaller and lighter. This is a great advantage that supports its application in various portable consumer electronic devices.

Disadvantages of lithium batteries

There are several key points that could affect the Lithium Battery Market as follows:

i) Expensive


Although the cost of lithium batteries is constantly falling, they are still higher than that of nickel-cadmium cells. However, with the variety of applications, advances are being made in improving technology and reducing costs.

ii) Inverter Compatibility


Lithium battery is currently used in automotive and DC applications. When we talk about household use of lithium batteries? Then I can say –  Very rare case.

What is the price of a lithium battery?

Wie hoch ist der Preis für eine Lithiumbatterie?

The cost of lithium batteries has already decreased by around 60-70% in the last few years and this trend is expected to continue with massive investments in improving technology and processes. An estimated 73% of all lithium battery storage systems are manufactured in China, and the Middle Kingdom is planning to continue building many multi-gigawatt systems in the future. Given the cost sensitivity in the Indian market, manufacturers find it very profitable to source batteries from China instead of sourcing them from the domestic market, where there isn’t much capacity anyway. As China moves towards higher quality, better density batteries, it finds it useful to dispose of lower quality products in India.

Lithium battery price list in 2022

The price of a lithium battery is measured in kWh. The price for a 1 kWh battery is currently 25,000, which is supplied in 80 Ah / 12.8 volts.

Last updated on: Fri, January 7, 2022

Battery models Price all inclusive
6 Ah / 75 Wh 1,875
12 Ah / 150 Wh 3,750
20 Ah / 250 Wh 6,250
30 Ah / 385 Wh 9.625
40 Ah / 500 Wh 12,500
80 Ah / 1,000 Wh 25,000
80 Ah / 2,000 Wh 50,000


The price of a lithium battery is almost   twice that   of a lead-acid battery, but for the next 2-3 years the cost of a lithium battery will be the same as that of lead-acid batteries.

How does the price of lithium batteries vary depending on the type of battery technology?

There are three technologies in the lithium battery: the oldest is lithium-ion, the current one, which is very popular for storage, is lithium phosphate, while lithium polymer is the most technologically advanced battery.

Here is the price range of lithium batteries in India in 2021, by battery type

Battery technology Minimum price Maximum price
Lithium-ion Rs. 2,250 / piece Rs.15.0000 / piece
Lithium phosphate Rs. 3,750 / piece Rs. 25.0000 / piece
Lithium polymer Rs. 7,500 / piece Rs. 50.0000 / piece
