Stacked Lithium Battery

A stacked battery is a modular energy storage system where multiple battery units are connected to increase capacity or power output. These batteries are designed to be “stacked” vertically or horizontally, allowing users to customize their energy storage based on needs. Commonly using lithium-ion technology, stacked batteries are popular for home energy storage, solar systems, and backup power. They offer scalability, efficiency, and flexibility, making them ideal for both small and large energy demands. Their modular design also simplifies maintenance and upgrades, ensuring long-term reliability.

Advantages of Stacked Lithium Battery

Large capacity

By stacking multiple battery modules, larger energy storage capacity can be obtained to meet the needs of high energy consumption equipment or long-term use.

High power output

The stacked design allows multiple battery modules to be connected in parallel, providing higher power output capabilities and suitable for scenarios with instantaneous high power demand.

Scalability

The stackable lithium battery can add or remove modules as needed to achieve flexible expansion and capacity adjustment of the system.

System stability

The stacked design can provide better battery balance and temperature management, ensure balanced performance of each battery module, and reduce the occurrence of hot spot effects.

High space utilization

The stacked design can effectively utilize space and reduce the equipment footprint, making it suitable for application scenarios with limited space.

Structure and components

Battery Cells

At the core of the stacked battery, you’ll find individual cells that are responsible for storing energy. Each cell typically consists of a positive terminal (cathode), a negative terminal (anode), and an electrolyte that allows ions to flow between them. In a lithium-ion stacked battery, the cells are often made of lithium metal oxide for the cathode, graphite for the anode, and lithium salts as the electrolyte.

Battery Separator

A separator is placed between the layers of cells to prevent short circuits. It allows ions to pass through but keeps the positive and negative terminals apart.

Conductive Connectors

These connectors link the individual cells, allowing the battery to transfer energy between them. They play a crucial role in maintaining efficient electrical conductivity and ensuring that the stacked battery works as a single unit.

Thermal Management System

Stacked batteries, especially lithium-ion variants, generate heat during charging and discharging. A thermal management system, including heat sinks or liquid cooling, helps dissipate heat and maintain an optimal operating temperature.

Protective Circuitry

To prevent overcharging, overheating, or deep discharging, stacked batteries are often equipped with battery management systems (BMS). These systems monitor the health of the battery and ensure safe operation.

Working principle

Energy Storage

During charging, lithium ions move from the cathode (positive terminal) to the anode (negative terminal), where they are stored. The flow of electrons through the external circuit provides the electric current needed to charge devices or vehicles.

Energy Release

When the battery discharges, the stored lithium ions move back from the anode to the cathode, releasing energy in the form of electrical current. This process powers your device or vehicle.
