Batteries having lithium as their anode are lithium batteries. They have a history dating back to 1980-1990s.
Lithium batteries have completely revolutionized the portable electronics market and are finding increasing application in the electronic, solar, mobile phones, medical equipment, power backups, and EV markets. These batteries have high energy density and the technology is witnessing significant cost reductions.
Prior to lithium batteries, nickel-cadmium batteries were prevalent. However, cadmium is a hazardous material, and the batteries have a high self-discharge rate. Lead- acid batteries were also not successful due to their dependence on hazardous metal lead and their low energy density.

Price Trend of Lithium Battery for Last 10 – 20 years
The price of lithium batteries have declined by more than 80% in the last decade. According to new analysis from Guide house Insights, lithium-ion cell prices will further fall by more than 40%. According to a report published by IHS Market, the average cost of lithium-ion batteries will fall to $100/kWh in 2023. Rapid growth in scale, increased application in EVs and growing manufacturing capacity globally shall lead to this price decline. The price of a lithium battery is measured in kWh. At present the price of 1 kWh battery is 25,000 which comes in 80 Ah /12.8 Volt ratings.
1. Lead Acid
Lead acid batteries are very heavy and bulky. They are not ideal for fast charging as they overheat at the time of charge. Its short typical cycle life ranges from 300 to 500 cycles. However, they are easily available in the market and are known for their reliability.
VRLA or a valve-regulated lead-acid battery is also known as sealed lead-acid (SLA) battery. These batteries are maintenance free and do not require electrolyte or water. VRLA batteries are used in telecom cells as well as UPS replacement batteries, and in emergency lighting and other applications.
3. Lithium Battery
Lithium battery is light-weight and has high energy density and electrochemical potential. Lithium-ion is a low maintenance battery and the self-discharge is also less.
Lithium batteries are gaining rapid momentum as they are finding increased application in electric vehicles and for power backups in renewable energy systems. Lithium batteries can also be used in cars, homes UPS, toys and remote controls.
Difference between Lead Acid & Lithium Batteries
The main advantage of lithium batteries is its porta They are lightweight weighing about 12 kg and can be easily carried anywhere. They weigh nearly 25% of a typical lead-acid battery.
2. Fast Charging
Lithium batteries can charge maximum within 2 to 4 hours whereas lead acid batteries generally take 10 hours charge time. Fast charging is the need of the hour in today’s fast-moving world.
3. Long Life
Lithium batteries have a life of over 10 years on average. They can handle more than 2000 times of charge-discharge cycles. For lead acid batteries, it is low about 1500 times life cycle.
It is safe from child. All positive and negative terminals are connected under plug-in-play connecting socket. That's why it doesn't any spark in time of connecting battery to inverter connection.
5. Aesthetic Look
We can install it as like refrigerator, tv, or any decorative items.
Why Lithium Battery is Future?
Lithium batteries are finding increasing application in emerging technologies. Lithium batteries are more efficient and charge faster when compared to lead-acid batteries. it has a longer lifespan and higher efficiency and provides reliable, stable, long-lasting power. That is why this technology is gaining popularity in power backup systems using solar energy and in electric vehicles. Though lithium batteries are much more expensive up front, they are maintenance-free and have a longer lifespan when compared to lead-acid batteries. It is expected that the cost of lithium batteries will be at par with lead acid batteries in the next 2-3 years.
Lithium Battery for Electric Vehicles
Given their high energy density ratio and good high-temperature performance, lithium batteries are ideal to be used in electric vehicles. They are also lightweight which helps in reducing the overall weight of the automobile. Lithium batteries also have a low self-discharge rate, which means that they are better when compared to other batteries at holding a full charge over time. All these features make lithium batteries best suited for electric cycles, cars as well as motor cycles.
Lithium Battery in Home with Home Inverter
The market for lithium-ion batteries in India is expected to grow at a CAGR of 34. 8% during the period of 2019 – 2024. Electric vehicle and energy storage systems in both commercial and residential applications should drive future growth for the lithium-ion battery market in India. Other applications such as solar power plants, military, telecom, power tools, etc. also account for the large lithium-ion battery applications in India. The EV market is set to explode in India and the government has also undertaken various initiatives to promote electric vehicles in the country.
Disadvantages of Lithium Batteries
1. Expensive – Though the cost of lithium-ion batteries is constantly falling, it is still higher than that of Nickel-cadmium cells. However, given its large number of applications, progress is being made towards improving the technology and reducing cost.
2. Protection against high temperature – Care is to be taken when charging lithium-ion batteries as they are sensitive to high temperatures. They require protection from being overcharged and discharged too far. Excessive heat causes faster degradation of these batteries.
3. Natural Degradation – Lithium batteries suffer from aging. An average battery can withstand 500 – 1000 charge-discharge cycles. These batteries hence need to be replaced from time to time and can become a headache if embedded in the equipment. Storage in a cool place at 40% charge reduces the aging effect.
4. Hazardous when transported – We have already discussed that a lithium-ion battery is sensitive to high temperatures. Some say that these can even explode when overcharged/ overheated. Hence many airlines put a limit on the number of batteries a passenger can carry. When shipped in larger quantities, transportation by water is advisable.
5. Low on maintenance – Lithium-ion batteries do not require any maintenance to ensure their performance. Few other types of batteries like nickel-cadmium cells require discharge to prevent memory effect.
