There are three main types of lithium-ion batteries (li-ion): cylindrical cells, prismatic cells, and pouch cells. In the EV industry, the most promising developments revolve around cylindrical and prismatic cells. While the cylindrical battery format has been the most popular in recent years, several factors suggest that prismatic cells may take over.
Because Laserax provides laser solutions for battery manufacturing, we are watching these developments closely. Before we go over what’s coming, let’s do a quick overview of the two types of batteries.
What Are Prismatic Cells
CTECHI prismatic cell is a cell whose chemistry is enclosed in a rigid casing. Its rectangular shape allows efficiently stacking multiple units in a battery module. There are two types of prismatic cells: the electrode sheets inside the casing (anode, separator, cathode) are either stacked or rolled and flattened.
For the same volume, stacked prismatic cells can release more energy at once, offering better performance, whereas flattened prismatic cells contain more energy, offering more durability.
Prismatic cells are mainly used in energy storage systems and electric vehicles. Their larger size makes them bad candidates for smaller devices like e-bikes and cellphones. Therefore, they are better suited for energy-intensive applications.
Prismatic cells are much larger than cylindrical cells and hence contain more energy per cell. To give a rough idea of the difference, a single prismatic cell can contain the same amount of energy as 20 to 100 cylindrical cells. The smaller size of cylindrical cells means they can be used for applications that require less power. As a result, they are used for a wider range of applications.
CTECHI specializes in battery design, production, marketing and services in many different industry sectors, such as Telecom Base Stations, AGV, RV, E-Forklift, E-Sweeper, Golf Carts, Golf Trolley, Gardering Machine, Boats, Cleaning Machine, Solar Energy Storage and so on. We are so familiar with all these projects because we`ve work on them for years.
Size
Many of project purchasers and the project development engineer are meeting various problems when they work with the battery selecting and sourcing, such as short cycle life caused by cell differences, terrible heat cooling management, slow and poor developing ability of a more functional BMS, difficulties of integrating BMS and other parts by communication protocol and on. We are deeply aware of all these existing problems, along with the market growing, lithium batteries are solution engineering require much better engineer team than many other products. CTECHI were built to solve this problems for you, and save much of money and energy of sourcing a reliable lithium battery products.
Connection
Because prismatic cells are larger than cylindrical cells, fewer cells are needed to achieve the same amount of energy. This means that for the same volume, batteries that use prismatic cells have fewer electrical connections that need to be welded. This is a major advantage for prismatic cells because there are fewer opportunities for manufacturing defects.
Power
Cylindrical cells may store less energy than prismatic cells, but they have more power. This means that cylindrical cells can discharge their energy faster than prismatic cells. The reason is that they have more connections per amp-hour (Ah). As a result, cylindrical cells are ideal for high-performance applications whereas prismatic cells are ideal to optimize energy efficiency.
Example of high-performance battery applications include Formula E race cars and the Ingenuity helicopter on Mars. Both require extreme performances in extreme environments.
The EV industry evolves quickly, and it’s uncertain whether prismatic cells or cylindrical cells will prevail. At the moment, cylindrical cells are more widespread in the EV industry, but there are reasons to think prismatic cells will gain in popularity.
Why Prismatic Cells Might Be Taking Over
First, prismatic cells offer an opportunity to drive down costs by diminishing the number of manufacturing steps. Their format makes it possible to manufacture larger cells, which reduces the number of electrical connections that need to be cleaned and welded.
Prismatic batteries are also the ideal format for the lithium-iron phosphate (LFP) chemistry, a mix of materials that are cheaper and more accessible. Unlike other chemistries, LFP batteries use resources that are everywhere on the planet. They do not require rare and expensive materials like nickel and cobalt that drive the cost of other cell types upward.
There are strong signals that LFP prismatic cells are emerging. In Asia, EV manufacturers already use LiFePO4 batteries, a type of LFP battery in the prismatic format. Tesla also stated that it has begun using prismatic batteries manufactured in China for the standard range versions of its cars.
The LFP chemistry has important downsides, however. For one, it contains less energy than other chemistries currently in use and, as such, can’t be used for high-performance vehicles like Formula 1 electric cars. In addition, battery management systems (BMS) have a hard time predicting the battery’s charge level.
When it comes to battery pack production demand, energy storage systems (ESS) are just as important as electric vehicles. ESSs are already using prismatic cells and it is very likely that they will keep using them. Prismatic cells have a longer cycle life, are less dangerous, and come at a low cost compared to cylindrical cells. You can watch this video to learn more about the LFP chemistry and why it is gaining in popularity.
Prismatic Cells in Energy Storage Systems
When it comes to battery pack production demand, energy storage systems (ESS) are just as important as electric vehicles. ESSs are already using prismatic cells and it is very likely that they will keep using them. Prismatic cells have a longer cycle life, are less dangerous, and come at a low cost compared to cylindrical cells.
The Switch to Prismatic Batteries
With its tabless cell design, high energy density, and low manufacturing cost, Tesla’s 4680 cylindrical cell is probably the most noteworthy battery cell at the moment. But recently, Elon Musk has talked about the advantages of prismatic cells, and Tesla has begun using them in certain car models.
The 4680 cylindrical cells haven’t been replaced by prismatic cells yet, but Tesla’s next move will be telling of what the future holds. Will they replace the 4680’s Nickel-Cobalt-Aluminum oxide (NCA) chemistry with the LFP chemistry? If so, will they switch to prismatic cells, the preferred format for this chemistry? With the increased cost of raw materials around the world, it is a strong possibility.
The Life Span
Overall, due to the different manufacturing processes, the cylindrical type will have slightly more cycles than the prismatic LiFePO4 cell.
Weight
Cylindrical cells will be heavier because most of them have steel shells. Prismatic cells are lighter because most of them use stainless steel and aluminum shells.
Manufacturing Cost
Because cylindrical cells have a long history and simpler processing and production technology, the manufacturing cost will be relatively cheaper, while prismatic cells are relatively new, and due to the limitations of processing technology and no special standardized production specifications, So the manufacturing cost will be higher.
Damage Cost
In a battery pack composed of cylindrical cells, if one cell is damaged, it will not seriously endanger the entire battery pack. At the same capacity, damage to a prismatic cell will seriously affect the entire battery pack, which means that the cost of damage is high.
Easy to Expand
Since most scenarios currently require large-capacity batteries, the option of capacity expansion has become a consideration for many people. Relatively speaking, it is more difficult to expand the capacity of cylindrical cells. Under the same capacity, cylindrical cells may need tens of thousands of cells, but prismatic cells may only need a small number, which means that prismatic cells may require only a few cells. The expansion of prismatic LiFePO4 cells is simpler.
Differences in Chemical Activity
Due to the internal structure and shape of the cylindrical cell, the electrolyte distribution inside the cell is very uniform, which is conducive to full utilization. In the inner corners of the prismatic cell, some electrolytes will be in an idle state, and the prismatic structure will exert a certain pressure on the corners. A simple summary is that the utilization rate of the electrolyte will be relatively low.
Heat Dissipation
Cylindrical cells will have better heat dissipation, because there is no way to arrange them as closely as prismatic cells, and there will be gaps between the cells, which provide space for heat dissipation.
