Southern financial reporter Yang Yuxin intern Zheng Ning Guangzhou report

at present, the 2025-2026 winter car test is in full swing. In the bitter air of Inner Mongolia's gnasite and minus 30 ℃, a test new car wrapped in black and white camouflage drove on the ice and drove at high speed on the Circular Road, emergency brake, steering, the roar of the engine echoed on the snowfield.

As the "touchstone" of the extreme performance of vehicles, extremely cold test is a necessary key link before the new car goes public. Up to now, there have been more than 1,000 dental Rock test vehicles in this Test season, covering famous brands such as BMW, Audi, Porsche, ideal, BYD, Lantu, dark blue, zero run, etc, among them, new energy vehicles account for more than 90%.

Behind this extreme challenge of "Ice and Fire, battery technology innovation becomes the key-& mdash; The breakthrough of ultra-wide temperature range battery has solved the extreme temperature adaptation problem of new energy vehicles and many fields.

Recently, Shenzhen Institute of Advanced Technology of Chinese Academy of Sciences (hereinafter referred to as "Shenzhen Institute of Advanced Technology") "carried out in-depth work on the revitalization of patent achievements, the case of boosting the industrialization of ultra-wide temperature range battery patent technology was successfully selected into the third batch of excellent cases of patent transformation and application by the State Intellectual Property Office in 2025.

It is reported that in 2023, the energy storage technology team of Shenzhen advanced Institute has developed China's first long service life product with wide temperature range, low cost and cell, with a minimum working temperature of minus 70 ℃, the highest working temperature reaches 80 ℃ above zero, and normal charging can be realized at minus 30 ℃ low temperature, thus realizing wide temperature range application scenarios of cold and hot summer.

Limited by battery materials, the working temperature of traditional lithium ion batteries is 0-40 ℃, and the discharge performance of lithium batteries will decrease significantly when it is lower than 0 ℃.

However, our countryThe territory is vast, and the temperature varies greatly with the region and season. The winter temperature in the northern region can be as low as minus 40 ℃, while the summer surface temperature in the southern region can be as high as above 50 ℃, traditional lithium-ion batteries cannot adapt to such extreme temperature conditions, which will cause on the one hand, the abundant clean energy sources such as solar energy and wind energy in the northern region to be directly connected to the grid for power supply; On the other hand, electric vehicles cannot be started in winter and smart phones are automatically shut down, difficult situations such as frequent spontaneous combustion of electric vehicles in summer.

In view of the above pain points, as early as 2013, Tang Yongbing, a researcher at Shenzhen advanced Institute, proposed the topic of developing lithium ion batteries with higher energy density and wider working temperature range by using alloying metal materials, the goal is to develop lithium ion batteries that can maintain more than 70% battery life in the environment of minus 30℃.

After nearly ten years of research and development, the team has successfully invented a new wide-temperature lithium battery technology based on aluminum-based negative electrode. The working temperature range of the product has been widened to minus 70 ℃ to minus 80 ℃, and it has been widely used in outdoor energy storage, outdoor monitoring, photovoltaic energy storage and other fields.

Researchers from Shenzhen Advanced Research Institute told Southern Finance and Economics reporters that the new aluminum-based ultra-wide temperature range battery product has been monitored by smart grid in Northern China, the promotion and application of large-scale storage of clean energy and other major national demand fields, such as the megawatt-hour wide temperature range energy storage system developed in cooperation with the national power investment group has been applied in Daqing photovoltaic energy storage project, the energy consumption of auxiliary equipment such as industrial air conditioners is reduced by 89.3 percent.

In addition to the energy storage field, the ultra-wide temperature range also brings key technological breakthroughs to the new energy vehicle industry. Researchers from Shenzhen Advanced Research Institute said that the performance optimization of batteries in low temperature environment is a major direction for the current development of electric vehicles, however, the ultra-wide temperature range of this new battery can effectively relieve the mileage anxiety of new energy vehicles and help them popularize in the whole climate and scene.

On December 26, 2024, the team of Shenzhen advanced Academy applied the wide temperature range battery to new energy vehicles for on-board verification for the first time, and conducted the first comprehensive test in the national automobile quality inspection and testing center. The test data shows that in the case of no heating module, in the CLTC (China light vehicle test cycle) working condition test of minus 30℃, the mileage reaching rate is as high.

Under the empowerment of capital, the industrialization process of ultra-wide temperature range battery patented technology is accelerated. According to Wu Xiaoli, director of the transformation department of Shenzhen advanced Institute, based on the new battery technology, the 23 related patents of this team rely on Shenzhen advanced Institute and offer 65 million yuan for intellectual property rights, the technology transfer and transformation were successfully realized, and Shenzhen Zhongke Ruineng Industrial Co., Ltd. was established in March, 2017. At present, it has started to build an ultra-wide temperature range cell and PACK (battery module) manufacturing base in Guangyuan, Sichuan province, covering an area of 200 mu, with an initial investment scale of 1.27 billion yuan.

From the application scenario, wide temperature range batteries are gradually extending from the two core fields of energy storage and new energy vehicles to emerging fields such as low-altitude economy, robots, commercial aerospace, etc, accelerate full scene coverage ".

Among them, the commercial aerospace industry is expected to become the core driving force for the growth of battery demand in wide temperature range. With the accelerated networking of LEO satellite constellations, the market demand for space energy storage batteries continues to expand. By the end of 2025, the number of commercial satellites in orbit in China had reached about 800. In 2025, 50 commercial space launches were completed and 311 commercial satellites were successfully put into orbit. At the same time, china has declared more than 200000 LEO satellite constellation resources to the International Telecommunication Union. In the future, the magnitude growth of the number of satellites will directly drive the explosion of battery demand in wide temperature range.

It is worth noting that the commercial space field is more important to the newThe performance requirements of energy batteries are extremely stringent-space environment has complex challenges such as extreme temperature difference, high vacuum, strong high-energy particle radiation, etc., which requires batteries to have super wide temperature range adaptability, the ideal working temperature range must cover 120 ℃ below zero to 120 ℃ above zero. Ultra-wide temperature range battery is expected to seize the core share in the commercial aerospace battery market due to its outstanding extreme environment adaptation advantages.
