The battery electrode sheet is the core component of a battery, playing a crucial role in conducting electricity and facilitating electrochemical reactions. It consists of a positive electrode sheet and a negative electrode sheet, which are separated and connected by an electrolyte to form the electrochemical reaction area of the battery, enabling the conversion between chemical energy and electrical energy.

By adopting the bidirectional synchronous stretching technology, the mechanical strength is high and balanced, with uniform pore structure and good consistency. Produced by the blow molding method (optimized relative to the extrusion method), it has a unidirectional microporous structure and excellent thermal closure performance. Coated with nano-alumina/bombshell, etc., it significantly improves heat resistance, dimensional stability and electrolyte wettability. The coating has strong adhesion to the electrode sheet, which can reduce the defective rate of the cell during encapsulation and improve the interface contact. Using a mixed coating of PVDF/aramid and ceramics, it combines high heat resistance, excellent adhesion and cost efficiency.

The solid-state electrolyte membrane is the core functional layer of a solid-state battery. It replaces the traditional liquid electrolyte and performs the dual functions of conducting lithium ions and isolating electrons.

Electrode Tab Insulation Tape is a special insulating and protective tape specifically designed for lithium battery manufacturing. It is primarily attached to the metal tabs of the battery, and its core functions are to prevent metal burrs from puncturing the separator and causing a short circuit, to protect the solder joints from electrolyte corrosion, and to provide fixation and insulation.

In lithium-ion batteries, the aluminum strip primarily serves as the positive electrode current collector, collecting the current generated by the active material and outputting it externally. Furthermore, it plays a crucial role in the electrode framework, thermal conductivity, and structural support.

Aluminum-nickel composite strips are bimetallic conductive materials that tightly bond aluminum and nickel through a special process. They combine the lightweight and high conductivity of aluminum with the corrosion resistance, high strength, and excellent weldability of nickel.

The core function of pure nickel strip is as a highly conductive and corrosion-resistant connecting conductor. Due to its extremely low resistivity and low heat generation, it is often used as a tab connector or busbar in power battery packs or energy storage systems to ensure the safe transmission of high currents and reduce energy loss.

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.
