The Basics of Lithium Batteries
How a lithium battery works
The working principle of lithium batteries mainly involves the charge transfer process. In lithium-ion batteries, there are two processes involved: charging and discharging:
Charging process: When a lithium battery is charged, the positive end of the battery produces lithium ions, which then move through the electrolyte to the negative end of the battery. The negative electrode is usually composed of a layered carbon material with many micropores, and these lithium ions that reach the negative electrode are embedded in the micropores of the carbon layer.
Discharge process: When the battery is discharged, the lithium ions in the negative electrode will move back to the positive electrode through the electrolyte again, and release electrons, resulting in an electric current. This current can then be used by a variety of devices.
Classification of lithium batteries
Lithium batteries are mainly divided into two categories: lithium metal batteries and lithium ion batteries.
Lithium metal batteries use lithium metal or its alloy as the negative electrode material, while lithium-ion batteries use lithium alloy metal oxide as the positive electrode material and graphite as the negative electrode material.
According to the state of its electrolyte, lithium-ion batteries can also be divided into liquid lithium-ion batteries, polymer lithium-ion batteries and all-solid ion batteries.
What is a Stackable Lithium Battery?
A stackable lithium battery is an energy storage system formed by stacking multiple battery modules together. These modules are connected in series or parallel to increase the total capacity and voltage of the battery system. Using multiple battery modules also provides redundancy, allowing the system to continue operating even if one or more modules fail.
Components of a Stackable Lithium Battery
A stackable lithium battery consists of several key components, including:
Battery modules
These are the individual battery cells that make up the system. Each module contains one or more battery cells that are connected together in series or parallel to produce a higher voltage or capacity.
Battery Management System (BMS)
This is a device that monitors and controls the performance of the battery system. The BMS is responsible for balancing the charging and discharging of each battery module, as well as protecting the system from overcharging, overheating and overdischarging.
Inverter
This device converts the DC voltage generated by the battery system into an AC voltage that can be used to power electrical equipment.
Cooling system
Stacked energy storage batteries generate heat during operation, so a cooling system is needed to keep the temperature within a safe range.
How Does a Stackable Lithium Battery Work?
Laminated energy storage batteries work by storing electrical energy in the form of chemical energy. When the battery is charged, a chemical reaction within the battery module creates a potential difference between the positive and negative terminals. This potential difference is maintained until the battery is discharged, at which point the chemical reaction reverses and the electricity is released.
The battery management system plays a vital role in ensuring that the battery module is charged and discharged in a balanced and controlled manner. If one or more battery modules overcharge or overdischarge, the BMS will automatically adjust the charge and discharge of the other modules to maintain balance.
Advantages of Stackable Lithium Batteries
Large capacity:
By stacking multiple battery modules, you can obtain larger energy storage capacity to meet the requirements of high-energy devices or long-term use.
High power output:
The stack design allows multiple battery modules to be connected in parallel to provide higher power output, which is suitable for scenarios requiring instantaneous high power.
Scalability
Stackable lithium batteries can add or remove modules as needed to achieve flexible system expansion and capacity adjustment.
System stability
The stacked design provides better battery balance and temperature management, ensuring balanced performance of each battery module and reducing the occurrence of heat spots.
High space utilization
The stack design effectively uses space and reduces the device footprint, which is suitable for application scenarios where space is limited.
GYCX Solar reminds us that the design and installation of stackable battery system need to consider the requirements of inter-module connection, thermal management, safety protection and other aspects to ensure the stability and safety of the system. Therefore, in the selection and use of stackable lithium battery system, should follow the relevant specifications and standards, and seek professional stackable lithium battery manufacturers technical support and advice.
