Lithium batteries are quickly becoming the preferred batteries for future battery banks. Even now, their penetration is growing, and they have begun to displace the old lead-acid batteries that have long been employed in the solar industry. This form of solar battery is already popular among LoomSolar customers. Why? What are the benefits of a lithium battery over a regular battery?
Batteries made with lithium
Lithium, a metal and the lightest solid element, is the actual star. Lithium in the form of an ion (positively charged due to the loss of an electron) is more stable than pure lithium. Batteries, energy-dense devices that can be recharged several times without losing efficiency, are made up of this positively charged particle.
The ability of lithium ions to travel across battery electrodes without being modified by chemical reactions has enabled a revolution in storing electrical energy and utilising it when needed. Because of its capacity to be intercalated, or lodged, into the electrode materials themselves. Step by step, a conquest took happened.
Lithium batteries’ advantages
Many people are intrigued by the insides of a lithium battery, so let’s get down to business. In comparison to lead-acid batteries, the following are the most significant benefits of lithium-ion batteries. The 1 kWh lithium-ion battery price in India may exceed the price of other batteries but the advantages of buying lithium ion batteries are worth it.
Energy density is higher
The accumulator’s capacity is determined by the energy density. When comparing two similarly sized batteries from both technologies, lithium triples the capacity of lead-acid. A lead-acid battery has an energy density of 40 Wh/kg, but a lithium battery has an energy density of 120 Wh/kg.
Increased voltage and improved energy efficiency
The most electronegative chemical element is lithium. Without getting into details, the increased oxidation capacity of lithium results in a higher voltage. And a lead-acid battery’s cell generates 2 volts, the lithium-phosphate cell produces 3.2 volts, while the lithium-ion cell provides more than 3.6 volts. Lithium-ion batteries score a whopping 98 percent when it comes to overall performance. Is it a large amount or a little amount? It’s estimated to be over 80% in lead acid. Lithium makes greater use of energy since it performs better and loses less energy.
A more favourable energy profile
The energy profile calculates the battery’s level of charge in relation to charging time and usage. The energy profile of lithium batteries is greater.
Depth of discharge
While lead-acid batteries have their optimum usable life when discharged to 20% and it is not suggested to discharge them to more than 50%, lithium accumulators do not have this problem and may be discharged to 100%. Although many manufacturers usually allow a reserve to accomplish an 80 percent drain, lithium batteries’ longevity is affected by the depth of discharge, but to a smaller amount than lead-acid batteries.
A lithium battery is a device that uses the flow of electrons between two electrodes to store and release electrical energy. When the batteries are recharged, this flow of electrons is re-established from the negative electrode (anode) to the positive electrode (cathode).
