The fifth time! EVE wins the China Patent Award Again

Recently, the China National Intellectual Property Administration released the Decision on the Award of the 24th China Patent Award on its official website, and EVE won the "24th China Patent Excellence Award" for its patent of " a lithium battery positive electrode, lithium battery and its preparation method". This is the fifth time that EVE has won this award.

The China Patent Award was established in 1989 and is the highest honor in the Chinese patent field, recognized by the World Intellectual Property Organization (WIPO) of the United Nations. This award is a government department award specially awarded for invention and creation granted patent rights in China. The selection criteria include patent quality, technological progressiveness, application and protection measures and effects, social benefits and development prospects.

The award for patent excellence this time marks a high recognition by authoritative institutions of the research and development strength and technological innovation ability of EVE!

Core Technology of Electrode Process

This patent discloses a lithium battery positive electrode and a lithium battery containing the positive electrode, as well as a preparation method thereof, which solves the key technical problem of the instability of trivalent manganese in traditional technology leading to an increase in internal impedance of the battery and a decrease in battery discharge capacity. This technological breakthrough effectively improves the stability and safety of batteries, increasing their service life from about 3 years to over 10 years; Expand the usage temperature range of battery from -20 ℃ to 60 ℃ to -40 ℃ to 125 ℃; Double the high-temperature working efficiency of lithium batteries; And the industrial efficiency of the preparation process has been improved by 20%.

At present, this patented technology product is mainly applied in the fields of consumer batteries and power batteries. With the popularization of 5G technology, consumer batteries, as one of the key energy components supporting the Internet of Things, have seen rapid growth in power demand. The application scenarios are constantly enriched, including smart meters, smart security, smart cities, automotive electronics, smart wearables, power tools, LEV, smart homes, and more. The breakthrough of this patented technology effectively meets the needs of different customers, enhances production and delivery capabilities, and realizes unlimited possibilities for lithium batteries and smart life.

In the field of power batteries, with this patent as the core technology, we actively layout power and energy storage lithium-ion batteries, build a rich product system, and have multiple technical routes such as pouch NCM batteries, prismatic NCM batteries, prismatic LFP batteries, and large cylindrical batteries. They are applied in new energy vehicles, electric forklifts and other engineering equipment, electric ships and other fields, creating a full scenario solution for the energy internet, and helping to achieve carbon peak and carbon neutrality.
