Nickel-plated copper tabs are primarily used as negative electrode leads in lithium-ion batteries. They combine the high conductivity of copper with the oxidation resistance and easy soldering properties of nickel, and are mainly used in electric vehicle batteries and high-rate discharge applications. They effectively reduce battery internal resistance and improve high-current charge/discharge efficiency.

High-temperature adhesive tape for battery tabs is mainly used in the manufacture of lithium-ion batteries. Its core functions are insulation, short-circuit prevention, resistance to electrolyte corrosion, and secure encapsulation. It tightly wraps around the seam between the battery tabs and the aluminum-plastic film or casing, and is a key material for ensuring battery safety and performance.

The aluminum-plastic film roll for pouch batteries is a core material used for packaging lithium-ion battery cells. Its main functions are to protect internal electrode materials from oxidation by the external environment, prevent internal electrolyte leakage, and provide insulation and mechanical support.

Nickel-plated steel cylindrical casings are commonly used in batteries and precision electronic devices. Their core functions are to protect internal components, provide excellent electrical conductivity and corrosion resistance, and impart extremely high physical strength to the structure.

It mainly consists of three parts: high-purity organic solvents, electrolyte lithium salts (solute), and necessary functional additives. It can be formulated according to the specific ratios of anode and cathode raw materials.

The high-quality PVC heat shrink casing provides reliable external protection and insulation packaging for the battery. It has the functions of flame retardancy, wear resistance and protecting the appearance of the shell.

The laminated battery cell is a lithium-ion battery cell manufactured through the lamination process. Its internal structure is composed of positive electrode sheets, negative electrode sheets and separators stacked alternately, forming a multi-layer structure similar to a "sandwich".We can support customized liquid or solid-state battery cells.

With the rapid development of electric vehicles, energy storage systems, and portable electronic devices, battery technology has become the core driving force of the energy revolution. However, the safety, durability, and environmental adaptability of batteries remain the key challenges that restrict their large-scale application. The external protective structure of batteries serves as the first line of defense, and it not only needs to withstand mechanical impacts, thermal runaway, and chemical corrosion, but also needs to consider lightweighting, cost-effectiveness, and manufacturing efficiency. This article will explore the latest trends in the external protective structure of batteries and how they can promote reliability improvement from two dimensions: material innovation and process upgrading.
