LiFePO4 batteries, or Lithium Iron Phosphate batteries, are advanced rechargeable batteries known for their longevity, safety, and energy efficiency. They utilize iron phosphate as a cathode material, which offers enhanced stability and reduces the risk of thermal runaway, making them safer than other lithium-ion battery chemistries. LiFePO4 batteries are widely used in various applications, including electric vehicles, solar energy storage systems, and portable electronics, due to their high energy density and long cycle life.
These batteries are compact, handle many charge cycles, and don’t overheat or catch fire easily. Great for electric cars and home energy storage due to their reliability.
Different types of LiFePO4 batteries include cylindrical, prismatic, pouch, and large-format cells. Cylindrical cells, like AA batteries, offer more cycles but are heavier due to steel shells. Prismatic cells, ideal for electric vehicles, are lighter with square shapes. Pouch batteries are flexible, fitting smartphones, while large-format cells provide backup power for data centers.
Cylindrical ones, like AA batteries, are common in gadgets. The cylindrical type typically offers slightly more cycles compared to the prismatic LiFePO4 cell. Cylindrical cells tend to be heavier due to their steel shells, whereas prismatic cells are lighter as they often utilize stainless steel and aluminum shells.
Prismatic ones, with a rectangular shape, are great for electric vehicles. The square-shaped prismatic design enables a close arrangement of cells, whereas the cylindrical type inherently results in gaps. Cylindrical cells usually carry more weight due to their reliance on steel shells, while prismatic cells are lighter thanks to their usage of stainless steel and aluminum shells. Cylindrical cells, with their established history and simpler production, are cheaper to manufacture. Prismatic cells, being newer and constrained by technology and lacking standardized specifications, typically have higher manufacturing costs.
Pouch batteries, thin and flexible, fit well in devices like smartphones.
Large-format ones provide long-term backup power for places like data centers. Choosing the right type depends on your needs and where you’ll use it.
The pros of LiFePO4 batteries include a long lifespan, up to 10 times more charge cycles, and enhanced safety compared to traditional lithium-ion batteries. However, they are bulkier due to lower energy density and may have higher initial costs. Despite drawbacks, their advantages make them a promising option for sustainable power solutions.

While it is possible to mix 100Ah and 200Ah batteries, it is generally not recommended. Mixing batteries of different capacities can lead to imbalances, strain on both batteries, and reduced performance. It can also result in risks such as overcharging or undercharging. To ensure optimal performance and longevity, it is advisable to use batteries with matching capacities.
Cylindrical lithium battery is a kind of lithium ion battery, its shape is cylindrical, so it is called cylindrical lithium battery. The structure of a typical cylindrical battery includes: casing, cap, cathode, anode, separator, electrolyte, PTC element, gasket, safety valve, etc. Generally, the battery shell is the anode of the battery, the cap is the cathode of the battery, and the battery shell is made of nickel-plated steel plate.
Since Tesla's battery day in September proposed large cylindrical cells, large cylindrical cells have once again become the focus of the battery industry in the market. In addition to Tesla, China's leading cell factories have also begun to invest in the mass industrialization of large cylindrical cells.
According to the data shown by Tesla, the large cylindrical lithium battery will increase the energy by 5 times on the basis of the cylindrical cells, increase the mileage by 16%, and reduce the cost by 14%. Its technical temptation is very significant. However, during the period of rapid development of China's new energy vehicles in the past, first-line brands including CATL and BYD all focused on the technical route of square cells. At present, the industrialization of power batteries is basically based on square batteries, and even Tesla has purchased square batteries with a capacity of about 161Ah in China for use in one of its models.
From a technical perspective, both technical routes have their own value and advantages. In a complex battery system, although batteries account for the highest cost, in terms of safety and cost performance, we cannot only focus on one dimension of batteries. For example, Tesla has industrialized and applied the cylinder and to electric vehicles with energy exceeding 70KWH through advanced management system design. In fact, it is using advanced management to optimize the performance of the battery system.

● Advantages of small capacity flexibility
Due to size and process limitations of cylindrical cells, the capacity of a single cell is usually small. For example, ternary battery 3.5Ah, iron-lithium battery 6Ah, iron-lithium battery 15Ah, iron-lithium battery 20Ah, etc. Aside from electric vehicles and large-scale energy storage markets, in other fields, such as AGV, portable energy storage, and home energy storage, the capacity of single-module batteries is usually not very large. In practical applications, the large-capacity square cells positioned for automobiles and large-scale energy storage do not necessarily exactly match the market demand, including size and capacity.
The small-capacity cylindrical lithium battery can be connected in parallel to meet the battery module capacity needs of certain market demands. For example, the two types of lithium batteries 24V60Ah and 48V30Ah used in AGV cars are relatively common needs. Three types of cylinders, , and , can be combined in parallel to form the required 60Ah or 30Ah modules. At the same time, there are more flexible operation possibilities in the space structure to meet the design requirements of different models.
● Cost advantage
In the production and manufacture of all lithium-ion batteries in lithium battery companies in the world, the process standardization of cylindrical lithium battery is the highest, and it is also the earliest commercialized battery. The assembly efficiency is significantly higher than that of square batteries and pouch batteries. The winding process of cylindrical batteries has reached the level of 200PPM with the gradual improvement of automation. Even though the efficiency of large cylindrical lithium batteries is slightly lower than that of traditional / cylindrical cells, it is much higher than the efficiency of stacking or winding processes of square cells and pouch cells (usually around 10PPM).
The reason for the small capacity of the cylindrical lithium battery is that the strip-shaped continuous pole piece after coating is cut into strip-shaped small pole pieces, and the miniaturization of the pole piece can improve the utilization rate of the entire pole piece material. Usually under the same screening criteria and automation level, the material utilization rate of cylindrical cells is 3-5% higher than that of square cells.
● The heat dissipation effect is obvious
Lithium-ion battery fires are all caused by thermal runaway, and the spread of thermal runaway is also the main concern of battery system safety performance. Cylindrical structure is the most likely solution to thermal runaway, while square and pouch structures are basically unsolvable. The low capacity of a single cell causes thermal runaway to release less energy, which is different from high-energy, large-capacity square cells or pouch cells. At the same time, with the gradual improvement of material safety, the heat release caused by thermal runaway is reduced, which significantly increases the safety of the battery system.
The curved surface structure of the cylindrical lithium battery limits the heat transfer process between the cells to a certain extent, and has a certain positive effect on the spread of thermal runaway. However, square batteries and pouch batteries are basically unsolvable in this regard. Furthermore, with the promotion of the full-tab process, the heat transfer of cylindrical cells is more on the upper and lower end caps of the cells, and the heat transfer on the curved surface will also be reduced.
The above is some analysis and thinking based on different application scenarios of lithium batteries with different structures. Although the focus is on analyzing the advantages of cylindrical lithium battery, it is undeniable that cylindrical cells have shortcomings in certain application fields. At the same time, it is also necessary to objectively understand the own advantages of square cells and pouch cells.
