For scenarios such as electric aviation, high-end equipment, and fast-charging power batteries, lithium-ion batteries are subject to stringent requirements for both high power and high energy density. The bottleneck is concentrated at the level of key materials. This technology focuses on high-power and high-energy-density lithium-ion batteries, developing key materials for the positive and negative electrodes, as well as supporting systems. The positive electrode is optimized for a balance between high specific capacity and structural stability, while the negative electrode is optimized for high capacity retention and lithium precipitation inhibition under fast-charging conditions. In addition, the technology combines electrolyte and electrode structure design to achieve synergy between materials, electrodes, and cells, supporting both high-rate charging and discharging and long-term durability. The technology can directly meet the product upgrade needs of cell manufacturers. At present, a pilot production facility has been built and validated, demonstrating the feasibility of material preparation and cell adaptation, and providing the basis for process scaling. The technology can provide services such as material preparation technology licensing, cell design adaptation support, pilot-scale production and production line construction guidance, performance evaluation, and personnel training.

This technology is aimed at developing a pulse electrochemical-mass spectrometry (EC-MS) combined analysis system for commercial batteries. It uses pulse electrochemical excitation to simulate dynamic loads under actual battery operating conditions, and combines high-sensitivity mass spectrometry to detect electrolyte gas generation and volatile intermediates in real time, achieving millisecond-level in-situ analysis. This provides direct experimental evidence for key issues such as electrolyte decomposition, gas generation failure, SEI evolution, and fast lithium extraction. The technology is suitable for research and development diagnosis, failure analysis, incoming material evaluation, and safety warning system construction in power batteries, consumer batteries, and energy storage batteries. A pilot installation has been completed and the feasibility and engineering suitability of the method have been verified. We can provide technical support for system installation, test method development, commissioned analysis services, and data interpretation training.
