The global capacity of lithium batteries has seen remarkable growth in recent years, driven by the surge in demand for electric vehicles (EVs), renewable energy storage solutions, and portable consumer electronics. For prismatic lithium-ion batteries alone, the market is valued at approximately USD 99.98 million in 2023, with projections indicating a significant rise to USD 342.5 million by 2030, reflecting a compound annual growth rate (CAGR) of 14.1% during the forecast period from 2024 to 2030. [1]
Prismatic lithium-ion batteries, characterized by their rectangular shape, are gaining traction in various applications because of their high energy density, longer cycle life, and improved safety features. Understanding the intricacies of prismatic lithium batteries becomes essential for stakeholders across industries.
Structure of Prismatic Lithium-ion Battery
For the structure of a prismatic lithium-ion battery, there are three features:
Aluminum Housing
Prismatic lithium batteries are typically encased in aluminum housing, which provides several advantages: [2]
- It offers high reliability and durability, ensuring that the prismatic battery can withstand various environmental conditions
- It contributes to the overall safety of the prismatic lithium-ion battery by minimizing the risk of leakage and thermal runaway, which are critical concerns in battery technology
- It is lightweight, which helps reduce the overall weight of the battery pack, making it adaptable for applications where weight is a significant factor, such as electric vehicles
Basic Components
Except for the aluminum shell, it also typically consists of the following components, including:[3]
- Positive Plate (Cathode) and Negative Plate (Anode)
- Diaphragm (Separator)
- Insulation Parts
- Safety Components (NSD, OSD, etc.)
These components work together to create a battery that is not only efficient but also safe for use at any time.
Better Customization, Better Space Utilization
Compared with cylindrical battery cells, the rectangular shape of prismatic cells allows for better space utilization within devices, as they can be designed to fit snugly into available compartments.[4] This efficient packing is particularly beneficial in applications where space is at a premium.
Furthermore, the modular design of prismatic battery cells enables manufacturers to adjust the size and capacity according to the requirements of the end product, enhancing flexibility in design and application.[4]
Performance of Prismatic Lithium-ion Battery
By its structure and design, prismatic lithium-ion batteries can excel at certain points compared with other types of batteries. It has:
Lower Internal Resistance
Prismatic lithium batteries are designed with larger electrode areas, which can reduce internal resistance. This lower internal resistance is crucial as it enhances the battery’s efficiency, allowing for higher discharge rates and faster charging times. The reduced resistance minimizes heat generation during operation, which not only improves performance but also extends the overall lifespan of the battery.[6]
Higher Package Reliability
As mentioned above, the robust aluminum housing of prismatic lithium batteries contributes to their higher package reliability. This rigid casing provides excellent mechanical stability and resistance to external stress, reducing the risk of damage from impacts or environmental factors.
Besides, this prismatic design also helps prevent swelling, a common issue in other battery types, thereby ensuring that the battery maintains its structural integrity over time. This reliability is particularly important in applications such as electric vehicles, where safety and durability are paramount.[4]
Better Thermal Management
In a prismatic lithium-ion battery, there is always an NSD (specifically a thin copper sheet), which is a mechanism for preventing thermal runaway. As NSD works, the copper sheet rapidly disperses the localized high current over a larger surface area, thereby reducing current density and preventing overheating.
This dispersion helps avert thermal runaway, a dangerous condition where escalating temperatures can lead to battery failure, fire, or explosion, thereby enhancing the overall safety and stability of the battery in scenarios where mechanical damage is a risk.[4]
Applications for Prismatic Lithium-ion Battery
By its structures and performance, prismatic lithium-ion battery is applied in the market of EVs and residential energy storage systems.
EVs
The EV market is experiencing exponential growth, significantly impacting the demand for prismatic lithium batteries. Several key trends are driving this growth:
Market Growth Projections: The market for electric vehicles pack is projected to reach $300 billion by 2030, indicating a robust demand for prismatic lithium batteries as a key component in EV.[7]
Government Regulations and Incentives: Many governments worldwide are implementing active regulations to reduce carbon emissions and promote electric mobility. For example, the U.S. Department of Energy provides loans to manufacturers for re-equipping or establishing facilities to produce advanced technology vehicles (ATVs) and components, including prismatic batteries.[8]
Technological Advancements: Continuous improvements in battery manufacturing technology, including a one-stop lamination line, are making prismatic lithium batteries more attractive for EV manufacturers as they improve the efficiency of battery production.
Residential Energy Storage System
Driven by the surging demand for efficient and reliable energy solutions, the market of residential energy storage systems still needs prismatic lithium-ion batteries:
Load Shifting and Peak Shaving: Homeowners can use prismatic lithium battery cells to shift energy consumption from peak to off-peak hours, reducing electricity costs. By charging the battery in low-cost periods and discharging in high-cost periods, users can optimize their energy expenses.
Integration with Renewable Energy: Prismatic lithium batteries are primarily used to store energy generated from solar panels. This integration allows households to maximize the use of renewable energy, storing excess energy produced during the day for use at night or during periods of low generation.
Market Projection: The global market for residential energy storage systems is projected to climb up continuously, with estimates indicating a compound annual growth rate (CAGR) of approximately 20% from 2023 to 2030. So, manufacturers are expanding their battery production capacities to meet this trend.[9]
