破局：攻克固態電池產業化核心瓶頸

當前，全球新能源產業正加速向更高能量密度、更高安全性的固態電池技術演進。固固界面接觸不良、阻抗高、孔隙率大等問題，是制約固態電池從實驗室走向規模化量產的核心瓶頸。作為目前行業公認最成熟的電芯致密化解決方案，溫等靜壓技術通過物理加壓實現電極與電解質的緊密耦合，成為打通固態電池產業化的關鍵裝備。利元亨與具備壓力容器制造經驗的優質企業聯合開發的溫等靜壓機，以精準可控的技術性能與全方位的安全保障，為全球固態電池量產提供堅實支撐。

溫等靜壓技術的核心原理基于帕斯卡流體壓強傳遞定律。在密封高壓容器內，介質將壓力均勻傳遞至電芯的各個表面，使傳統工藝中電極與電解質的 “點接觸” 轉變為全方位的 “面接觸”，有效消除界面間隙與內部應力集中。這種各向同性的加壓方式，能夠顯著降低電芯界面阻抗，減少內部孔隙率，提升整體結構一致性，為固態電池能量密度與循環壽命的提升奠定基礎。

Warm Isostatic Press: Building the Core Equipment Cornerstone for Solid-State Battery Industrialization

Breaking the Deadlock: Overcoming Core Bottlenecks in Solid-State Battery Industrialization

Currently, the global new energy industry is accelerating its evolution toward solid-state battery technology, which offers higher energy density and greater safety. Issues such as poor solid-solid interface contact, high impedance, and high porosity are the core bottlenecks restricting the transition of solid-state batteries from the laboratory to large-scale production.

As the industry's most recognized and mature solution for cell densification, warm isostatic pressing technology achieves tight coupling between electrodes and electrolytes through physical pressure application, making it a key enabler for solid-state battery industrialization. The warm isostatic press jointly developed by Lyric and qualified enterprises with experience in pressure vessel manufacturing provides solid support for global solid-state battery mass production with its precise and controllable technical performance and comprehensive safety guarantees.

The core principle of warm isostatic pressing technology is based on Pascal's law of fluid pressure transmission. Inside a sealed high-pressure vessel, the medium uniformly transmits pressure to all surfaces of the battery cell, transforming the traditional "point contact" between the electrode and electrolyte into a comprehensive "surface contact," effectively eliminating interfacial gaps and internal stress concentrations. This isotropic pressurization method significantly reduces the interfacial impedance of the cell, decreases internal porosity, and improves overall structural consistency, laying the foundation for enhancing the energy density and cycle life of solid-state batteries.

Hardcore: Precision-Controlled Ultra-High Pressure Equipment Capabilities

The vertical warm isostatic press is specifically designed for laboratory R&D and small-batch process validation, featuring an inner cylinder diameter of 160 mm, an internal volume of 18 L, an operating pressure range from 0 to 600 MPa, and an operating temperature range from room temperature to 150°C. For large-scale production requirements, Lyric Robot has simultaneously launched a horizontal warm isostatic press series, with inner cylinder diameters covering 300 mm to 400 mm, lengths up to 3 to 4 meters, and can be equipped with front-end and back-end automated material handling systems to enable automatic cell loading/unloading and continuous high-efficiency production.

In terms of core performance indicators, the equipment achieves high-precision process control: pressure fluctuation accuracy is maintained within ±2%, temperature fluctuation accuracy within ≤±3°C, and both pressurization and depressurization processes support multi-stage, freely controllable profiles. Custom pressurization curves can be tailored to the specific characteristics of different electrolyte materials, such as sulfides and oxides, effectively preventing the formation of micro-cracks inside the battery cell and ensuring process consistency.

The equipment's key configurations have been comprehensively upgraded: the pressure-bearing frame is precision-manufactured from special steel plates, offering high rigidity and strong load capacity; the high-pressure intensifier enables linear and precise pressure regulation; the integrated valve group and piping system ensure stable and reliable operation; and the touchscreen one-key automation control system greatly reduces operational complexity.

Safety is the lifeline of ultra-high pressure equipment. Lyric's warm isostatic press incorporates a multi-layered safety protection system: full-dimensional strength calculations, simulation analyses, and pressure tests are conducted on the ultra-high pressure vessel to ensure structural safety from the design stage; it is equipped with automatic overpressure and overtemperature alarms along with interlock shutdown devices; for hazardous gases that may be generated from sulfide electrolytes, an integrated hydrogen sulfide detection and protection system is included, ensuring safe and stable operation throughout the production process.

Empowerment: Build a Full-process Solution for Solid-State Batteries

As a world-leading provider of new energy equipment solutions, Lyric has built full-line capabilities covering the entire manufacturing process of solid-state batteries, including dry electrode preparation, electrolyte transfer, frame forming and stacking, isostatic pressing densification, as well as high-pressure formation and grading.

Leveraging its professional laboratory for solid-state battery equipment, the company conducts joint process verification with clients to jointly optimize cell manufacturing technologies.

From lab-scale process exploration to large-scale industrial production, warm isostatic pressing equipment is reshaping the manufacturing paradigm of solid-state batteries. Committed to in-depth research on core technologies and guided by the mission of "Endow Smart Manufacturing with Vitality", Lyric will deliver robust equipment support for China's new energy industry to seize the global technological high ground.
