How Do Lithium-Ion and Lead Acid Batteries Compare

As far as efficiency and reliability are concerned, nothing can beat Lithium-ion batteries. However, for off-grid storage systems, the lead-acid battery can be a better choice for a number of reasons. Basically, both types of storage units can store energy in an effective manner, but both have their own set of advantages and disadvantages. Given below are some points of comparison between the two. Read on to know more.
Cost
Cost is one of the main factors that draw a line between the two. If you get two batteries of the same capacity, the Lithium-ion battery will cost you three times more. Based on the size of the system you want to install, this can increase your expenditure significantly.
Although the lead-acid batteries have relatively lower price tags, they cannot last as long as their counterpart.
Capacity
The capacity of a battery pack refers to the amount of energy it can store. The great thing about these batteries are that they have a higher energy density than their counterpart. Therefore, these units can store more energy without occupying additional space. So, you can install more of these units in less space.
Depth of Discharge
The depth of discharge of a battery is the percentage of the power that can be drained without causing any damage to the unit. The disadvantage of lead-acid batteries is that they cannot be drained by more than 50%. On the other hand, Li-ion batteries can be safely drained up to 85% of their capacity.
Efficiency
Another good comparison point is the efficiency of these units. Unlike lead-acid batteries, lithium-ion batteries offer 95% more efficiency. In other words, 95% of the power stored in these units can be used. On the other side, the battery offers only 85% efficiency.
Lifespan
Just like solar panels, batteries continue to degrade with the passage of time. As a result, they lose their efficiency. After recharging a battery, when you discharge it completely, it is considered one discharge cycle. As far as the number of discharge cycles is concerned, lead-acid batteries cannot beat Lithium-ion batteries. Therefore, the latter offers a much longer lifespan.
Should you Install a Lead-Acid Battery or a Lithium-Ion Battery?
If you need to install a backup system, you can go for either a lithium-ion battery or a lead-acid battery. However, since the former offers a lot of advantages, you may not want to go for Lead-acid battery packs. Although lithium-ion units have a higher cost, they offer a great return on investment for many reasons explained above.
However, if you don't want to use your battery packs quite often, your ideal choice may be lead-acid batteries.
It was a brief comparison between Lithium-ion batteries and lead-acid batteries. Hopefully, this comparison will make it easier for you to make the right choice. Therefore, if you can afford it, you can spend more money and install lithium-ion battery systems.The ladle shroud nozzle for continuous casting is also called the protective sleeve. It is an important component connecting the ladle and the tundish. It is connected to the lower shroud of the sliding shroud device at the bottom of the ladle, and the lower end extends into the tundish.
The shroud is an important functional refractory material for maintaining casting and improving steel quality. The length of the shroud is generally 600-1800mm, the pipe diameter is 90-150 mm, and the structure of the ladle shroud nozzle is shown in Figure 2. Its use conditions are harsh and must have the following functions: excellent thermal shock resistance; good mechanical strength; excellent resistance to alternating corrosion of molten steel and slag, high oxidation resistance, and in addition, other suitable properties are required for some special steel grades.more information,please check here

Slide Gate Plate is a critical component in the continuous casting process, used to control the flow of molten steel from the ladle or tundish to the crystallizer. The following is a detailed description:
Role and Function
• Flow Control: The sliding gate plate adjusts the opening size of the nozzle through the sliding mechanism, thereby controlling the flow of molten steel. This is very important for maintaining a constant and controllable casting process.
• Operational Flexibility: The sliding gate plate allows operators to adjust the molten steel flow rate as needed during the casting process to adapt to different production requirements and conditions.
• Emergency Stop: In an emergency, the sliding gate plate can completely close the flow channel and stop the flow of molten steel, thereby preventing accidents and losses.

Slide gate plate for Converter
The slide gate plate is made of sintered corundum, fused corundum, fused zirconium corundum, zirconium mullite and other main raw materials. It is combined with new resin, formed by high pressure and fired at high temperature. It has the advantages of high strength, super hard, high temperature resistance and corrosion resistance, and strong thermal stability.
Stopper

Monoblock Stopper is used mainly for flow control on Molten Steel poured from tundish to mould. Monolithic Stopper is installed in the Tundish above the Sub Entry Nozzle and the gap between stopper head and Nozzle decide the throughput requirement of Molten Steel inside the Mould.
Argon can be blown into the tundish through argon inlet to prevent nozzle from Clogging ( specially designed feature wherever it is required we design and customise accordingly)
SPECIAL FEATURES:
o Facility for gas purging
o Anti oxidant properties
o Design and size as per customer’s requirement
o Clogging free casting for long sequence of casting
o Gas purging facilities to prevent alumina clogging (optional)
o Slag zone immersed part re-inforcement with special material for long life
o Argon sealing purging arrangement can be provided on customer’s request
o Wide range of formulation for withstanding oxidation and long sequence casting
o Different assembly methods for assured security even in long sequence casting
o We manufacture Silica free Oxy-bore ladle shroud for less corrosion and long sequence casting
