From new energy vehicles to medical equipment, from smart bracelets to drones, lithium batteries have a wide range of applications in daily life. As a key component of lithium batteries, the separator’s performance directly affects the battery’s capacity, cycle life and safety, and the manufacturing enterprises have relatively high technical barriers.
Jiangxi Huahao Lithium Energy Co., LTD., located in Yongxin County, Ji ‘an City, Jiangxi Province, is an enterprise specializing in the production and sales of consumer lithium-ion battery separators. Over the years, the company has adhered to independent innovation. The lithium battery separators it produces have gained a competitive edge due to the safety and reliability of their technology. It has been recognized as a National High-tech Enterprise and a specialized, refined, distinctive and innovative small and medium-sized enterprise in Jiangxi Province. This year, its annual output value is expected to reach 4 billion yuan.
In the latest round of national quality spot checks, Huahao delivered an outstanding performance report: the puncture strength of the lithium battery separator samples sent for inspection by the company reached 1100N (Newtons), far exceeding the national standard. Behind the data lies the company’s years of in-depth research in the field of materials science and meticulous study on the design of multi-layer heat dissipation structures.
Since its establishment, Huahao has actively carried out cooperation with universities such as Central South University and Nanchang University, jointly building doctoral research workstations and postdoctoral workstations, and creating an integrated collaborative innovation platform for industry, academia, research and application. Meanwhile, the company has established a professional R&D team and relies on advanced technology to maintain its leading position in the industry. At present, the company has obtained 18 invention patents, 19 utility model patents and 21 design patents.
In recent years, with the continuous rise of the “camping craze”, outdoor power sources have become best-selling products. The local overheating of traditional power supplies has become an urgent problem to be solved.
Huahao has focused on market pain points and launched technological breakthroughs. In the company’s dust-free workshop, Zhong Yuntao, the chief engineer of R&D at Huahao, is repeatedly adjusting the parameters of the diaphragm coating under a microscope. The ceramic composite diaphragm sample in his hand, although only 12 microns thick, can remain stable at a high temperature of 200 degrees Celsius. The high-temperature resistant technology developed by his team has increased the company’s product yield rate from 80% to 98%. After adopting the latest safety diaphragm developed by Huahao, the temperature of the battery cells during outdoor power supply use can be reduced by 20% to 30%.
Huahao has always kept pace with industry trends and promoted intelligent upgrades. The company is making large-scale replacements of intelligent robots and automated logistics equipment. Introduce advanced MES (Manufacturing Execution System) to build a digital and transparent factory; Introduce deeply integrated automation and intelligent perception technologies to achieve millisecond-level early warning of potential risks and intelligent closed-loop processing.
In the production command center of Huahao, data analyst Hu Gong is closely watching the fluctuating numbers on the large screen. MES is the “digital brain” of the factory. If there is any parameter deviation in any process, the system will issue a warning within 10 seconds. He introduced that in 2024, the company launched an intelligent quality inspection system, reducing the number of quality inspection team members per shift from 20 to 5, while increasing the detection accuracy rate from 95% to 99.9%.
“Ding Dong!” ” The mobile phone of Wu Youping, the purchasing manager of the company, popped up a warning: The inventory of aluminum-plastic film is only enough for three days of production. In such cases, the supply chain system will automatically place an order with the supplier and receive a confirmation receipt five minutes later. Wu Youping introduced that through the digital supply chain platform, Huahao has achieved data intercommunication with 10 core suppliers, and the raw material delivery cycle has been shortened from 15 days to 5 days.
On the computer of Huahao’s Marketing Department, the CRM (Customer Relationship Management) system shows a new demand from a certain drone manufacturer: to obtain samples of fast-charging semi-solid batteries within two weeks. In the past, this was an impossible task. Zou Tengfei, the head of the company’s Marketing Department, said, “Nowadays, the CRM system can automatically match similar cases, and the R&D team can produce a solution within 48 hours.”
The agile response capability has shortened the product customization cycle of Huahao from one month to two weeks. Wu Xinxing, the chairman of the company, has done the math: By applying digital technology, the cost per watt-hour of semi-solid batteries has been reduced by 0.15 yuan, and the company saves over 30 million yuan annually.
“To have a place in the industry, one must achieve ‘what others don’t have, we have; what others have, we excel at.'” ” Wu Xinxing said that the company will, based on semi-solid battery technology, focus on promoting the research and development of all-solid batteries to solve the problem of no liquid electrolyte leakage and further enhance battery safety.
