A Li-Ion battery is made up of several cells connected to each other in series and in parallel according to the necessary voltage and the energy requirements of the device it is intended to supply. It is therefore assembled with the cylindrical cells (which we more commonly call “accumulators”), which have the shape of a small tube and measure 1.8 cm in diameter and 6.5 cm in length.
These are the ones that are most often found (at least in recent years) on laptops, smartphones, and all devices that must be light or miniaturized, transported, or used for transport.
The world of electric mobility obviously immediately took hold of these batteries: small in size, light, with remarkable autonomy and great longevity, they had everything to please manufacturers.
So, Lithium technology is clearly replacing the old lead battery. But what makes these two types of batteries different?
Recharging the battery
To be recharged, a lead battery needs a lot of energy. Indeed, recharging is done by "re-mixing" the acid contained in the battery. It is gasification. This process requires more energy than the lead battery can deliver afterward.
Charging a lead battery has many disadvantages:
The recharging time is particularly long: 6 to 8 hours
Fast and partial recharging damages the battery.
A lead battery charger only measures voltage, apart from extreme temperatures influence the gasification process, which can lead to poor recharging due to lack of information from the charger.
This poor recharging decreases the battery life.
The Lithium battery is much more efficient at charging. Partial charges are very well supported and 50% of the battery can be recharged in 30 minutes. This characteristic of Lithium batteries allows less powerful and less bulky batteries on board because the recharging cycles are much shorter and therefore may be more numerous. Manufacturers therefore optimize their vehicles using the lithium battery. Lithium battery chargers are more sophisticated and adapt recharging according to voltage, temperature and charge level.
Weight / Dimensions
Lead-acid battery: 30kg per kWh
Lithium battery: 9kg per kWh
Not only are Lithium batteries lighter than lead at equal power, but they also have the advantage of being very flexible . Indeed, you can give Lithium batteries particular shapes that will facilitate integration into your vehicle.
Maintenance
A lead-acid battery requires relatively high maintenance costs. Indeed, a lead battery needs regular water make-up, maintenance of the filling circuit, and cleaning of the poles in order to avoid oxidation.
In addition, vehicles or machines operating with a lead battery need a dedicated charging space due to the emission of gas. These gases must be evacuated using a suction and ventilation system. The costs of this structure are obviously substantial. Contact now the China Lithium Ion golf cart battery factory to install a Lithium battery in your vehicle. Lithium batteries do not generate any of these costs. No need for recharging air with a special structure. Lithium batteries, once installed are ready to operate.
Lifetime
A lithium battery lasts 3/4 times longer than a lead acid battery, without losing its efficiency over time.
Safety
Lead-acid batteries are relatively dangerous because of the escaping gas. They are particularly prohibited in food production (except lead "gel" batteries). China custom ev lithium ion battery factory batteries are on the contrary very safe. They can be IP67 and therefore withstand the most severe environments. In addition, the automatic disconnection of the vehicle battery when it is not working protects the battery but also its users.
The FLASH BATTERY remote control system also makes it possible to check all possible battery anomalies in real time and to receive automatic notifications.
Charging, weight / size, maintenance, lifespan, safety here are all the points that allow us to affirm that the Lithium battery is a high-performance and efficient solution, especially for electric vehicles.
