With the explosive growth of the global new energy industry, the performance and adaptability of core battery components have become the focus of the industry. According to Google data, the company has deployed over 100 million lithium-ion batteries in its global data centers, replacing traditional lead-acid batteries to double efficiency and reduce space requirements . This trend has directly driven the demand upgrade for battery supporting components. As a key guarantee for battery safety and performance, the material selection and process adaptability of battery guantlets (Guantlet) have become the core of enterprise procurement decisions. Currently, the two mainstream materials in the market—woven (polyester) and non-woven guantlets—how to match different production scenarios? What core advantages do they each have? This article will analyze with industry data and product details.

According to industry reports, the market size of guantlets for lead-acid batteries in China will grow from 15 billion yuan to 30 billion yuan between 2025 and 2031, with a compound annual growth rate (CAGR) of 8.5%. The new energy vehicle and energy storage sectors will contribute the main growth, accounting for over 60% of the market share by 2031 . Behind this growth is the higher requirements of battery manufacturers for guantlet material adaptability and process stability. As a core component for battery plate group isolation and electrolyte conduction, the material selection of guantlets directly affects battery cycle life and safety performance. The two mainstream materials—woven (polyester) and non-woven—are covering different production scenarios with their respective characteristics.

The material selection of battery guantlets must strictly match the type of production equipment. The two materials have their own focuses on cost and adaptive processes, and both meet the physical and chemical performance requirements of the "People's Republic of China Machinery Industry Standard (JB/T10054-2010)" . The core differences are as follows:

Woven guantlets are made of high-strength polyester yarn through four core processes: "polyester yarn weaving → dipping and drying → pipe drawing forming → customized cutting". The production process strictly follows industry standards to ensure that key indicators such as tear strength and acid resistance coefficient meet the requirements . Its significant advantage lies in its dense structure and high mechanical strength, which can effectively adapt to the high-pressure filling process of powder filling production equipment, maintain shape stability during battery charge-discharge cycles, and avoid powder leakage or plate group short circuits. Currently, woven guantlets are widely used in high-end fields such as new energy vehicle power batteries and industrial energy storage batteries, making them the core choice for scenarios requiring high stability.

Non-woven guantlets are processed from non-woven materials. Compared with woven guantlets, they have lower production costs, and there is little difference in physical and chemical properties (such as porosity, DC resistance, and acid immersion weight loss) from polyester materials , fully meeting the technical requirements of conventional battery production. This type of guantlet is more suitable for paste extrusion production equipment. With good air permeability and electrolyte adsorption capacity, it can improve the adhesion efficiency of paste-like active substances and optimize battery charge-discharge performance. In cost-sensitive scenarios such as electric forklifts, UPS power supplies, and portable electronic devices, non-woven guantlets have become the mainstream choice, helping enterprises control costs while ensuring product quality.

To meet the production needs of different battery models, guantlets support full-size customized production. Customers need to confirm four core parameters in advance: ID hole diameter × T number of tubes × Pitch center distance × H height. For example, for large-size plate groups of new energy vehicle power batteries, large-aperture and multi-tube guantlet products can be customized; for small portable batteries, the center distance and height parameters can be optimized to improve battery space utilization. Manufacturers will conduct precise cutting and forming processes according to the parameter requirements to ensure perfect fit between the guantlet and the battery plate group. At the same time, they will strictly follow the inspection rules of industry standards to conduct full-process testing on appearance, size, and physical properties .

As the new energy industry transforms towards "high efficiency, lightweight, and environmental protection" , battery guantlets will also usher in technological upgrades. In the future, woven guantlets will gradually adopt recycled polyester materials to reduce carbon emissions; non-woven guantlets will further improve mechanical strength through process optimization to expand high-end application scenarios. Regardless of material iteration, "material adapting to equipment and precise parameter customization" remains the core logic for guantlet selection. Enterprises need to choose the most suitable guantlet solution based on their own production equipment type, product positioning, and cost budget.

Against the backdrop of the continuous expansion of the new energy market, the material selection and customized service capabilities of battery guantlets have become the key for enterprises to enhance their core competitiveness. The "dual-track parallel" of woven and non-woven guantlets not only meets the differentiated needs of different production scenarios but also provides cost-effective and high-performance diversified choices for the industry.
