Introduction

In the context of the global energy transformation and the vigorous development of the new energy industry, new energy batteries such as lithium batteries have become the core power source for new energy vehicles, energy storage systems, consumer electronics, and other fields. The safety and performance of new energy batteries are directly related to the development of the entire new energy industry, and the selection of high-performance auxiliary materials is an important guarantee for improving the safety and performance of batteries. New energy battery tape, as a key auxiliary material for battery cell winding, tab fixing, insulation protection, and battery pack bonding and sealing, is required to have excellent high temperature resistance, chemical corrosion resistance, electrical insulation, and mechanical properties to adapt to the harsh working environment of batteries. Hunan Lvzhimei New Material Technology Co., Ltd., with its deep accumulation in the high-temperature tape industry and keen insight into the development of the new energy industry, has developed a series of new energy battery tapes with excellent performance through continuous R&D and innovation, which are widely used in the production of various new energy batteries and have become a reliable supplier of battery materials for many well-known new energy enterprises. This article will comprehensively interpret the performance characteristics, application scenarios, and corporate advantages of Lvzhimei’s new energy battery tape, providing a reference for the material selection of new energy battery enterprises.

Core Performance Requirements of New Energy Battery Tape

The working environment of new energy batteries is complex and harsh, with frequent temperature changes, contact with electrolytes and other chemical substances, and high requirements for electrical insulation and mechanical stability. Therefore, new energy battery tape must have the following core performance:

High Temperature Resistance: Batteries will generate a lot of heat during charging and discharging, especially in high-rate charging and discharging and overcharging conditions, the internal temperature of the battery will rise sharply. The tape must be able to withstand high temperatures of 150°C or even higher without degumming, deformation, or combustion, to prevent thermal runaway of the battery.
Chemical Corrosion Resistance: The battery electrolyte is a corrosive organic solution, and the tape must be able to resist the erosion of the electrolyte for a long time without performance degradation or dissolution, to ensure the long-term stability of the battery structure.
Excellent Electrical Insulation: To prevent short circuits between battery cells, tabs, and battery packs, the tape must have high electrical insulation performance, with a high breakdown voltage and low dielectric loss, to effectively isolate current.
Strong Adhesion and Mechanical Properties: The tape needs to be firmly attached to the battery pole pieces, diaphragms, and shell surfaces, and have good tensile strength and elongation to withstand the mechanical stress during battery winding, assembly, and use without breaking or falling off.
Environmental Protection and Safety: The tape must be non-toxic, harmless, and free of heavy metals and harmful substances, and meet the environmental protection standards of the battery industry. At the same time, it should have good flame retardancy to prevent the spread of fire in case of battery fire.

Performance Characteristics of Lvzhimei’s New Energy Battery Tape

Lvzhimei’s new energy battery tape is independently developed for the performance requirements of the new energy battery industry, with a number of excellent performance characteristics that fully meet the high standards of battery production:

Targeted High Temperature Resistance Design

The tape adopts a special high-temperature resistant base material and adhesive formula, with a long-term use temperature of up to 200°C and an instantaneous high temperature resistance of 260°C. It can remain stable in performance and intact in structure in the high-temperature environment generated during battery charging and discharging, effectively preventing degumming and deformation caused by high temperature, and providing reliable protection for the battery internal structure. In the high-temperature aging test of batteries, the tape still maintains good adhesion and insulation performance after long-term high-temperature treatment, without any adverse effects on the battery performance.

Strong Resistance to Electrolyte Corrosion

The tape is made of high-quality chemical-resistant materials, which has excellent resistance to the erosion of various lithium battery and sodium-ion battery electrolytes. After long-term immersion in the electrolyte, the tape’s adhesion, tensile strength, and insulation performance remain basically unchanged, without swelling, dissolution, or performance degradation. This characteristic ensures that the tape can maintain long-term stability in the battery internal environment, effectively fixing the tabs and insulating the battery cells, and avoiding battery failure caused by tape damage.

Ultra-High Electrical Insulation Performance

As an H-class insulating material, the tape has a breakdown voltage of up to 6000KV and excellent electrical insulation performance, which can effectively isolate the current between battery cells, tabs, and battery packs, preventing short circuits and ensuring the safe operation of the battery. The insulation performance of the tape is also stable in high temperature, humidity, and other harsh environments, without being affected by the external environment, providing a reliable insulation guarantee for the battery.

High Adhesion and Excellent Mechanical Properties

The tape adopts a high-performance pressure-sensitive adhesive with good initial adhesion and holding power, which can be firmly attached to various surfaces such as battery pole pieces, diaphragms, aluminum plastic films, and metal shells, even on rough surfaces, it can maintain good adhesion and prevent edge warping and falling off during battery winding and assembly. The tape has a tensile strength of more than 135N/25mm and an elongation of 70%, with good mechanical properties, which can withstand the mechanical stress during battery production and use without breaking, ensuring the structural integrity of the battery.

Environmental Protection and Flame Retardancy

The tape is produced in strict accordance with the ROHS, REACH and other international environmental protection standards, without heavy metals, halogens, and other harmful substances, and the production process is green and environmentally friendly, meeting the environmental protection production requirements of the new energy battery industry. At the same time, the tape has good flame retardancy, which can self-extinguish after leaving the fire source, without producing toxic and harmful gases, effectively preventing the spread of fire in case of battery fire and improving the safety of the battery.
