    Since the spontaneous combustion accident of new energy buses in Shenzhen in April, there has been a debate about domestic power batteries
    .
    Experts said that there is still a gap
    between domestic battery products and foreign countries in terms of consistency and electronic control.
    Compared with other technical routes, lithium iron phosphate batteries are still the most in line with the current safety needs
    of domestic new energy buses.

    Experts clearly pointed out that buses are mass public transportation, with a large capacity of personnel loading, and once there is a problem, it takes a long
    time to escape and evacuate.
    Therefore, the management of power battery system should first consider safety factors, and the quality of materials used in the battery and the battery group technology are very high
    .
    For similar accidents such as spontaneous combustion of Shenzhen buses, experts believe that lithium iron phosphate batteries are the most suitable technical choice
    for electric buses through the analysis of the current mainstream battery technology route.

    From the perspective of product technology, first of all, lithium iron phosphate batteries designed according to power can also be quickly charged; Secondly, at this stage, the mass production maturity of lithium iron phosphate is higher than that of ternary materials and multi-component composite materials; From the material level, lithium iron phosphate has higher safety
    than ternary materials and multi-component composite materials.
    Of course, ternary materials and multi-component composite materials have advantages
    over lithium iron phosphate in terms of energy density.

    Since 2014, China's new energy vehicle sales have entered the fast lane, and the power battery market is in short supply, but there is still a big gap
    between domestic batteries and foreign products.
    Although there are many production enterprises, there are not many
    that really have the ability to match the whole vehicle.
    In terms of integration capabilities, production consistency and safety, there is indeed a big gap
    between domestic batteries and multinational companies.

    Experts said that in order to make the development of power and energy storage technology meet the application and market demand of new energy vehicles, new energy and smart grid, we should focus on the development of safe and reliable high-specific energy lithium-ion batteries, focus on the research and development of key battery materials, including positive and negative electrode materials, electrolyte materials, etc.
    , while combining the design, optimization and integration of core components and battery systems, adhere to independent innovation, break through key technologies, and promote the development and application of China's next generation of energy storage and power batteries
