The density is up to 500Wh/kg (watt hour/kg), and the electric aircraft equipped with it can even realize manned aviation... Recently, at the Shanghai Auto Show, Ningde Times released the condensed battery technology. What is a condensed state battery? Focusing on the electrochemical reaction changes of ultra-high specific energy chemical materials, the condensed battery adopts a high dynamic bionic condensed electrolyte, builds a micron level adaptive network structure, adjusts the interaction between chains, and improves the dynamic performance of the battery and lithium ion transport efficiency while enhancing the stability of the micro structural stability. Our condensed state batteries and semi solid state batteries are not the same type, "emphasized Wu Kai, the chief scientist of Ningde Times. The positive and negative electrodes of condensed state batteries can match various high specific energy materials, and they are not limited by the shape of the shell, but the square shell can reflect its best performance. The commentator at the Ningde Times Shanghai Auto Show said, "In electrochemistry, the safety performance of batteries is strongly related to the energy density of positive and negative electrode materials. Condensed state batteries significantly improve the safety performance of batteries and can have high safety while ensuring high specific energy. Currently, we have developed 6 series to 9 series condensed state batteries, which can achieve the goal of no fire or explosion even when the battery cells are disassembled Having a higher battery energy density, Wu Kai stated that condensed state batteries are the latest innovation in materials and material systems in the Ningde era. Condensed state batteries aggregate a series of innovative technologies, including ultra-high specific energy positive electrodes, new negative electrodes, isolation membranes, processes, etc., making them not only excellent charging and discharging performance, but also high safety performance. The series of innovative technologies have enabled this condensed state battery to break through the ceiling that has long restricted the development of the battery industry in terms of high specific energy and high safety, and will activate a new electric scene with high safety and lightweight as the core demands. Compared to traditional lithium-ion batteries, condensed state batteries have a higher battery energy density, with a value of up to 500Wh/kg, which is 42% higher than the current theoretical upper limit of energy density (350Wh/kg) for liquid lithium-ion batteries. Energy density is the core technical indicator of power batteries. It is understood that 500Wh/kg is not yet the upper limit of energy density for condensed state batteries. With the advancement of technology, higher energy density may be achieved in the future. In terms of safety, if the liquid electrolyte leaks, the flowing liquid electrolyte may cause a wider range of short circuits, generate high-voltage arc, and cause battery combustion and explosion. The network structure of condensed battery connected with internal polymer can be adjusted adaptively to ensure structural stability and better thermal stability. The possibility of mass production this year depends on different positive and negative electrode materials, and the energy density of condensed state batteries also varies. We are currently collaborating with a manned aircraft company, "Wu Kai said. Ningde Times revealed that vehicle grade condensed state batteries with lower energy density can be mass-produced within the year. Wu Kai admitted that as a brand new product, the current cost of condensed state batteries is slightly higher. The research and development of condensed state batteries is for the needs of aviation batteries. The demand for aviation batteries is not high cost-effectiveness, but lightweight and high safety. Automobiles do not require such high energy density. When we develop cars, we will adjust the energy density appropriately, but
