The stacked lithium battery platform delivers industry-leading power, performance and longevity through intelligent power management. Its advanced cooling and technology allow for faster charging and discharging, allowing you to last longer with your battery. In addition, its stacked lithium cells offer superior thermal management and an excellent price/performance ratio.
Mechanical properties
The mechanical properties of stacked lithium batteries are important when designing electric vehicles. These batteries must be able to withstand various types of abuse that can damage embedded energy storage systems. Because of this, the researchers focused on determining the mechanical properties of lithium-ion batteries. To calculate these properties, the researchers devised a numerical model. This model, called a homogeneous finite element model, represents the entire battery as a homogeneous medium. This method allows the simulation of large battery packs.
The mechanical properties of tandem lithium batteries are similar to those of conventional batteries. The difference is the internal resistance of the winding unit. The wound cell of the laminated battery is higher than that of the laminated battery. This difference affects the decay rate of the battery capacity.
Energy Density
Compared with traditional lithium batteries, the energy density of stacked lithium batteries is higher than that of single-cell batteries. This is because the internal resistance of the tandem battery is low, while the internal resistance of a single-cell battery is high. The difference is mainly due to the internal resistance of the winding unit, which is usually of the unipolar type.
Although it has high energy density, its single cell capacity is not sufficient for grid applications. For this reason, batteries are often stacked to increase their voltage and current capabilities. However, this approach presents significant challenges, including impacting cycle life and reducing voltage stability.
Power density
Lithium-ion batteries (LIBs) have high energy density. However, a single battery does not provide enough energy to meet the demands of the grid. Therefore, cells need to be stacked in series or in parallel to increase their overall power density. However, this process presents many challenges to the stability, safety, and cycle life of batteries. Additionally, batteries can suffer from a condition called self-discharge, where the lithium within the battery is no longer mobile.
This battery also has a high discharge rate and thermal stability. This feature makes it ideal for many applications, including electric vehicles, power tools, and power station energy storage. However, it has a lower energy density and higher self-discharge rate than lithium cobalt oxide batteries.
Cost
The stacked lithium battery platform delivers industry-leading power and performance. Its intelligent power management enables higher discharge and charge rates.
Safety
The stacking of lithium batteries is not a new concept. In fact, a lot of research has been done on it. Among them, there are many publications on the safety of lithium-ion batteries. They include information on internal battery failures and the use of lithium plating in commercial lithium-ion batteries.
Application
High-power lithium batteries can be stacked to improve performance and improve safety. Stacking is a technique in which cathodes, anodes and separators are stacked in an alternating fashion. This method reduces errors and minimizes open circuit voltage drop. The invention provides a stacking process for high-power lithium batteries.
