What does our rack lithium battery include?
Lithium-Ion Cells: The heart of the battery is the lithium-ion cells, which store and release electrical energy. These cells typically consist of a positive electrode (cathode) made of a lithium-based compound, a negative electrode (anode) usually made of graphite, and a separator that prevents direct contact between the electrodes.
Electrolyte: The electrolyte is a conductive solution or gel that allows the movement of lithium ions between the positive and negative electrodes during the charging and discharging cycles. It typically contains lithium salts dissolved in an organic solvent.
Separator: The separator is a thin, porous material that separates the positive and negative electrodes of the cell while permitting the flow of lithium ions. It prevents short-circuiting and plays a crucial role in the safety of the battery.
Current Collectors: Current collectors are typically made of metal foils, such as aluminum for the cathode and copper for the anode. They provide electrical contact for the electrodes, enabling the flow of current into and out of the cell.
Packaging: The lithium battery is enclosed in a protective casing to ensure electrical insulation and mechanical stability. The packaging protects the cells from physical damage and provides a safe environment to prevent leakage or thermal runaway.
Terminal Connections: The positive and negative terminals of the battery allow for external electrical connections. These terminals are usually metal tabs or pins that extend outward from the casing, enabling the battery to be connected to an external circuit.
What advantage does the rack lithium battery have?
Voltage compatibility: Many modern power electronics systems and devices operate at 48 volts, making these batteries compatible with a wide range of equipment.
Efficiency: Compared to higher voltage systems, a 48V battery system can provide efficient power transmission and conversion while minimizing losses.
Safety: Lower voltage systems generally have a reduced risk of electrical shock and are considered safer to handle and operate.
Scalability: 48V battery systems can be easily configured in series or parallel combinations to achieve higher energy storage capacities if needed.
Cost-effectiveness: In many applications, 48V battery systems offer a good balance between cost and performance, making them a popular choice for various projects.
What is inside our lithium battery cells?
Positive Electrode (Cathode): The positive electrode is typically made of a lithium-based compound such as lithium cobalt oxide (LiCoO2), lithium manganese oxide (LiMn2O4), lithium iron phosphate (LiFePO4), or lithium nickel cobalt aluminum oxide (NCA). The positive electrode is where lithium ions are absorbed and released during the cell's operation.
Negative Electrode (Anode): The negative electrode is commonly made of graphite or other carbon-based materials that can intercalate lithium ions. During charging, lithium ions move from the positive electrode to the negative electrode, where they are stored as lithium atoms in the carbon structure.
Separator: The separator is a thin, porous material that keeps the positive and negative electrodes physically separated while facilitating the exchange of lithium ions. It prevents short circuits and allows the movement of ions through the electrolyte.
Electrolyte: The electrolyte is a conductive solution or gel that contains lithium salts dissolved in an organic solvent. It serves as the medium for lithium ion transport between the electrodes. The electrolyte also provides a pathway for the movement of electrons through the external circuit during charging and discharging.
Current Collectors: Current collectors are usually metal foils, such as aluminum for the cathode and copper for the anode. They serve as the electrical terminals of the cell, connecting the electrodes to the external circuit.
