Overview
The LN2142 is a cylindrical lithium-ion battery cell designed for high-performance applications. It is commonly used in devices requiring reliable and long-lasting power, such as laptops, power tools, and portable energy storage systems. The battery's design emphasizes safety, efficiency, and durability, making it a preferred choice for manufacturers. Lithium-ion technology underpins the LN2142's performance, offering a high energy density and low self-discharge rate. Its standardized dimensions and compatibility with existing battery management systems (BMS) further enhance its appeal in industrial and consumer markets.
Physical and Chemical Properties
The LN2142 typically features a metallic casing, providing structural integrity and protection against environmental factors. Its energy density ranges between 200-250 Wh/kg, enabling compact yet powerful energy storage. The battery operates effectively within a voltage range of 3.0V to 4.2V, with a nominal voltage of 3.7V. Chemically, the LN2142 utilizes lithium cobalt oxide (LiCoO2) or similar cathode materials, paired with a graphite anode. This combination ensures stable electrochemical performance and minimizes degradation over cycles. The electrolyte is a lithium salt in an organic solvent, optimized for ion conductivity and thermal stability.
Main Applications
The LN2142 is widely adopted in consumer electronics, including laptops, tablets, and smartphones, due to its compact size and high energy output. It is also a staple in power tools, where consistent discharge rates and robustness are critical. Additionally, the battery serves energy storage systems (ESS) for renewable energy applications, such as solar power storage. Industrial applications include medical devices, electric vehicles (EVs), and backup power systems. Its versatility and reliability make it suitable for both portable and stationary uses, catering to diverse energy demands across sectors.
Safety and Storage
Handling the LN2142 requires adherence to safety protocols to prevent thermal runaway or leakage. Avoid physical damage, excessive heat (>60°C), and exposure to moisture. Storage should occur in a controlled environment, ideally at 20-25°C, to prolong shelf life and maintain performance. Transport regulations for lithium-ion batteries, such as UN38.3 certification, must be followed. In case of damage, isolate the battery and consult hazardous material guidelines. Proper disposal or recycling through certified facilities is essential to mitigate environmental impact.
B2B Procurement Guide
When sourcing LN2142 cells, prioritize suppliers with ISO 9001 and ISO 14001 certifications to ensure quality and environmental compliance. Request detailed specifications, including cycle life (commonly 500-1000 cycles) and discharge rates (e.g., 1C or 2C). Batch testing reports and MSDS (Material Safety Data Sheets) should accompany orders. Bulk purchases often reduce unit costs, but verify minimum order quantities (MOQs) and lead times. Consider logistics, such as shipping restrictions for lithium-ion batteries, and negotiate warranties or return policies to safeguard against defects.
