Huahui Energy Wins First Chinese Patent Award for Large-Size Monobloc Batteries

Recently, the State Intellectual Property Office announced the results of the twentieth China Patent Award, Hunan Huahui New Energy Company Limited (hereinafter referred to as Huahui Energy) won the first China Patent Award for large-size monomer batteries, marking that its patented technology, “Column shaped lithium-ion battery core leaching method and its application in lithium-ion battery production (ZL201510839177.5)” and intellectual property protection work has been recognized by the authority. )” and the protection of intellectual property rights have been recognized by the authority.

The China Patent Award, established by the State Intellectual Property Office, is the only governmental award in China dedicated to rewarding inventions and creations for which patents are granted, and is recognized by the United Nations World Intellectual Property Organization (WIPO). The evaluation criteria of the award not only emphasize the quality of patents and the level of technological innovation of patents, but also focus on their application in market transformation, and also have strict requirements on the protection and management of intellectual property rights. Focusing on the R&D and production of lithium-ion batteries, the award is a high degree of affirmation of its technological innovation and intellectual property protection.

Breakthroughs in the industry's technical difficulties, setting the flag of technological innovation

The traditional lithium-ion battery cell production adopts the drip injection process, using the process to inject electrolyte penetration is slow and weak penetration, low production efficiency; at the same time, the drip electrolyte needs to be injected into a single, cumbersome production process, automated production is limited; and in the process of injecting electrolyte water and air control is difficult, prone to potential safety hazards.

In response to the above technical difficulties, Huawei Energy has created the first automated leaching device, which realizes the automated production of lithium-ion battery leaching process through highly efficient osmosis control technology, and fills the gaps of automatic leaching and injection technology for domestic and foreign battery cells. The patented technology effectively simplifies the production process, shortens the infiltration time, strengthens the penetration strength, improves the production efficiency, and solves the problem of large-size battery production; realizes the batch operation and automated scale production; and carries out the encapsulation process in a negative-pressure environment, which prevents and controls the invasion of water and air in all aspects, greatly reduces the time when the electric core is exposed, and effectively controls the overall quality and performance of the battery.

Based on the above technical support, the patented product can be adapted to -40 ℃ ~ 75 ℃ temperature range, ambient temperature adaptability is higher than ordinary lithium-ion batteries; cycle life of up to 10,000 times, lead-acid batteries and nickel batteries is more than 10 times, is more than 5 times that of the traditional 3.7V lithium batteries. At the same time, the annual self-discharge rate of the capacitive lithium-ion battery is only 5%, significantly reducing the cost of use. In addition, the battery maintains safe and reliable performance under overcharging, over-discharging, reverse charging, extrusion, puncture, and flooding.

Huawei Energy actively participates in the standardization of lithium-ion battery safety, joining the Ministry of Industry and Information Technology's Lithium-ion Battery Safety Standard Task Force as a full member. At present, the patented technology has been successfully applied to the all-material series of high-performance lithium-ion battery products represented by HTC, HFC, HCC, HMC, and NSC, which have obtained authoritative safety certifications from foreign countries, such as CE, ROHS, MSDS, KC, UL, and CQC, and have formed a complete set of technical specifications.

Utilizing the patented products, Huawei Energy has cultivated a number of high-quality customer resources, such as Xinming Toys, Jetta Toys, Spinmaster, Merchitu, Qisda, Saijia Group, Baijiali, Changhong Granbo, Sunten Industry, Jinyi Technology and other well-known domestic and international enterprises” and other well-known electronic product manufacturers. Specialized “widely used in intelligent toys, small appliances, LED lighting, intelligent car equipment, electronic cigarettes, digital products and other fields” and other consumer electronic products. At the same time, because the patented technology is suitable for large-size battery impregnation production, so that it can be further popularized and applied in the automotive industry, generator sets, energy storage base stations, high-speed railways, ships, electric power, military and other fields.

Emphasizing Intellectual Property Protection and Winning the Highest Patent Award

This time, Huahui Energy won the China Patent Award, marking that Huahui's lithium-ion battery production technology has been recognized by the authority, realizing the transformation of scientific research results of lithium-ion battery leaching technology and industrialization, and driving the rapid development of the lithium-ion battery industry chain with leading technology. Huahui Energy Chairman Gu Huijun said that in the future, we will continue to improve the independent innovation ability of enterprises, continue to improve the work of intellectual property rights, so that innovation becomes a powerful driving force for the development of enterprises, help the overall development of lithium-ion battery industry, and make greater contributions to the development of China's new energy industry.
