The Dalian Institute of Chemicals, Chinese Academy of Sciences, developed the world's highest specific energy lithium-sulfur battery pack

Recently, the "high specific energy, large-capacity lithium-sulfur secondary battery and battery pack" with independent intellectual property rights developed by Chen Jian's team of Dalian Institute of Chemicals, Chinese Academy of Sciences passed the scientific and technological achievement appraisal
organized by the China National Light Industry Federation in Beijing.

Lithium-sulfur battery is a kind of high-specific energy secondary battery with abundant raw material reserves, environmental friendliness and low cost, and it is also the closest to practical next-generation secondary battery technology
.

Jian Chen's team has overcome a series of lithium-sulfur battery engineering and technical problems, successively developed key materials and key components of high-performance batteries, and developed large-capacity lithium-sulfur batteries and battery pack technologies
.
According to the third-party test report, the specific energy of the 35 Ah battery reaches 566 Wh/kg (measured at 25°C), the specific energy of the 39 Ah battery reaches 616 Wh/kg (measured at 50°C), and the specific energy of the 1 kWh lithium-sulfur battery pack reaches 332 Wh/kg
.
This is by far the world's highest specific energy lithium-sulfur battery and battery pack
.

Recently, the team has made important progress in the practical application of batteries, and developed China's first set of 12 kWh lithium-sulfur battery-photovoltaic cell joint demonstration system with independent intellectual property rights, which has laid a technical foundation
for the practical application of lithium-sulfur batteries in energy storage power stations, vehicle power supplies and other fields.
