On November 18, 2023, Sichuan Liwang New Energy Technology Co., Ltd. held a special witness meeting, with the theme of "Mass Production Solid-state Battery Acupuncture Test Witness Meeting";Professor Wang Shunli from Southwest University of Science and Technology participated in the whole testimony meeting.

Professor Wang Shunli is the academic leader of the National Electrical Safety and Quality Inspection Center, an academician of the Russian Academy of Natural Sciences, and is one of the top 2% scientists in the world.

This witness meeting is different from the past, Pu Guobo, general manager of Sichuan Liwang New Energy Technology Co., Ltd., said: "Although it looks high-end relying on test instruments, what I want to do is a test that everyone can understand. According to Mr. Pu, this test is a solid-state battery jointly developed by their company and Southwest University of Science and Technology, which has the following characteristics:

High safety: The solid electrolyte is non-flammable, which greatly reduces the risk of thermal runaway.

High energy density: Compatible with positive and negative electrodes with high specific capacity, the energy density is greatly improved, exceeding 500Wh kg.

High cycle times: The use of oxide and polymer composite materials greatly improves the performance of the battery, which can reach 20,000 cycles.

Low temperature performance: Able to discharge to 70% in a low temperature environment of -40.

These qualities give the solid-state battery advantages in terms of safety, energy density, cycle times, and low-temperature performance. The purpose of the testimonial is to show the performance and characteristics of this solid-state battery, and to provide a better understanding and awareness of the development of solid-state battery technology.

General Manager Pu Guobo personally carried out extremely destructive behaviors on this solid-state battery at the witness meeting, such as piercing with nails, cutting with scissors, and cutting with a cutting machine. Although the battery was damaged, it was able to maintain its original voltage and discharge normally.

This shows that this solid-state battery has excellent durability and safety performance. Even in the event of severe damage, it was able to keep the voltage stable and continue to work normally. This is an important milestone in the development of solid-state battery technology, as durability and safety have always been one of the key challenges in the development of battery technology.

This testimonial provided strong support for the application and promotion of solid-state batteries, and also showed people the robustness and reliability of solid-state batteries in the face of extreme conditions. These characteristics make solid-state batteries have a broad application prospect in many fields, such as electric vehicles, consumer electronics, and energy storage systems.

As soon as the meeting was released, Tang Mingpeng, deputy county magistrate of Beichuan County, and Xie Jie, deputy director of the Investment Promotion Center of the Commerce and Economic Cooperation Bureau, went to Sichuan Liwang New Energy Base on December 1 to inspect the solid-state battery project.

During the visit, they met with Hu Yongcheng, general manager of the Guangdong base, and Liang Baixiong, chief engineer, to learn about the research and development of solid-state batteries.

The solid-state battery project has a R&D center in Guangdong, with production bases in Sichuan and Guangzhou.

At present, the project has successfully developed 4 mass-produced battery cells and 6 deliverable batteries

The two-wheeled national standard electric bicycle is 48V60AH and can run more than 150 kilometers.

The two-wheeled electric motorcycle and Meituan battery swap 60v60ah can run more than 150 kilometers.

Special military, drone, robot batteries.

Outdoor solid-state power supply.

Trolley box type outdoor power bank.

Solid-state power bank;

These batteries are suitable for low-speed vehicles, Meituan battery swapping, and consumer digital batteries. The project is the result of many experiments and 18 patents, and it is the first domestic enterprise to achieve mass production in the two-wheeled low-speed vehicle and battery swap industry.

The solid-state battery project plans to invest in a 10GWh production project in Mianyang, and has already negotiated with a number of investment institutions and manufacturers. This means that the project has a wide range of cooperation and development prospects.
