Should Nickel Hydride No. 5 battery technology develop in multiple directions in the future?

　　Even charging operating companies have proposed their own solutions. Yu Dexiang, chairman of Qingdao Telaidian, said in his speech that the use of Telaidian's pile-less charging and group management and group control cloud charging system can monitor the status of electric vehicles during the charging process. Monitor and detect Nickel Hydride No. 5 battery problems in time to improve the safety of electric vehicles. Any network charging through special calls will reduce the possibility of burning the car by 70%.

　　Many industry insiders said that no method is omnipotent. The safety of electric vehicles is not just a problem for Nickel Hydride No. 5 battery companies, but a systematic project that requires the joint efforts of material suppliers, Nickel Hydride No. 5 battery equipment suppliers, Nickel Hydride No. 5 battery companies, and OEMs. .

　　Diversified technical routes

　　What kind of lithium Nickel Hydride No. 5 battery technology does the electric vehicle industry need? Is it necessary to solve the problem through high energy density? Qilu suggested that Nickel Hydride No. 5 battery companies relax their thinking and consider this issue based on actual conditions. Today, there are still a large number of lead-acid batteries entering non-road areas on a scale of hundreds of thousands or millions of vehicles. There are also nickel-metal hydride batteries, an almost forgotten Nickel Hydride No. 5 battery technology that has been used in Japanese hybrid vehicles. China's Nickel Hydride No. 5 battery and electric vehicle companies should also rethink their technological direction from a market and practical perspective, especially from a safety perspective.

　　But for new technologies that are becoming increasingly popular in the industry, such as high-nickel ternary batteries, solid-state batteries, and hydrogen fuel cells, Qilu also advises companies to remain cautious and calm. For example, high-nickel ternary batteries are more likely to release a large amount of heat than materials such as lithium manganate and lithium iron phosphate, and pose greater safety challenges.

　　In Qilu’s view, some of the solid-state Nickel Hydride No. 5 battery technologies currently on the market are not strictly speaking real solid-state Nickel Hydride No. 5 battery technologies. Solid-state Nickel Hydride No. 5 battery technology still has key technical difficulties that need to be overcome: Can energy density be increased by simply converting the commercial electrolyte into a solid-state electrolyte? Can it improve Nickel Hydride No. 5 battery safety? Moreover, if there are no revolutionary changes in pole piece technology, the conductivity problem cannot be solved using today's production methods of lithium Nickel Hydride No. 5 battery pole pieces.

　　Even hydrogen fuel cell technology, which is regarded as the ultimate solution for new energy vehicles, Qilu and his students have calculated that if China's 300 million electric vehicles were converted into hydrogen fuel cells, the consumption of fresh water to extract hydrogen would be It is so huge that a water-scarce country like China cannot bear it. Moreover, the process of extracting hydrogen energy also consumes electricity.
