Railway DC power supply 12V17AH lithium battery type introductionQuestion 4: You use the PTC effect to make a lot of important work in the field of lithium-ion battery safety. Here we want to ask, is this reaction? Or, is there possible to use the reversible PTC effect or the similar effect, when the temperature is too high, the temperature falls back to the battery again after the temperature is lowered? (After all, the power lithium-ion battery is still higher in the cost of the vehicle)

STR: The current result is irreversible. Once the PTC works, the battery will be expired forever. Now we are moving towards the direction you said, hoping to develop a reversible PTC material to achieve reversible heat protection of the battery. We have made certain progress in recent days, approximately 5 can be reversed, but the research still needs further deepening.

The Huizhong lithium battery has a high-spirited characteristics of the discharge platform, high safety, long life, and excellent low temperature performance.
Nanjing Xiahua battery capacity hourly rate: 1HR, 2HR, 3HR, 5HR, 8HR, 10HR, 20HR, 100HR

Question 5: I would like to ask the teacher, the solid phase conversion mechanism is compared with the traditional dissolution-deposition mechanism, although fundamentally inhibits the shuttle effect of the polysulfide, the nature of its solid phase react will not respond to the entire battery. Advancing an adverse effect? That is, it will not increase the electrochemical polarization of the battery due to the stagnation of the solid phase reaction, and the magnification performance is deteriorated or even meet the actual application needs?

STR: The questions you mention are very professional. At present, the solid phase conversion mechanism of * big problem is polarized, and the multiplier performance is poor. The main reason is two: 1, the sulfur surface passivation film is thicker, and the conductive properties of lithium are poor; 2, carbon surface The sulfur is thicker, and the electrode electron conductance is low. The above problems can be solved in a certain extent by regulating the electrolyte composition and electrode structure, and we are currently working in this regard. Overall, our current research is still in the basic research stage, and it will not talk about practical applications.
Zhou Jun, director of the Hami City Environmental Protection Bureau, said Hami City specially set up the leadership team of the central environmental protection inspector, requiring the members of the members to cooperate with the Central Environmental Protection Insugation Group. As the main member of the Environmental Protection, the Environmental Protection Agency will be transferred to the central environmental inspector group. At present, the six transfer places are verified in the first time, and 3 pieces have been resolved in the first time of refinement measures. Wang Yong, the head of the Aksu Regional Environmental Monitoring Detachment, said: “The Aksu Regional Department attaches great importance to the transfer author of the Ethimbus Eighth Environmental Protection Inspector, requiring regional Environmental Protection Agency, and counties (cities) Environmental Protection Agency. Grasp the rapid handling of the transfer organs hosted by the Central Environmental Protection Insugation Team.
