　　CATL/Vision AESC/Huineng/Honeycomb CR2450 batteryInnovation Technology Tracking

　　News from China Energy Storage Network: The dual superimposed effects of subsidy reduction and intensified market competition are driving innovation in power CR2450 batterytechnology.

　　In 2019, there were many innovative changes in the field of power CR2450 batterytechnology at home and abroad, which helped to further improve the energy density and reduce the cost of power batteries, reflecting the development trend of power CR2450 batterytechnology.

　　Overall, the development of power CR2450 batterytechnology is mainly reflected in the following aspects:

　　The first is the optimization of cell size, module structure and PACK design; the second is the optimization and upgrading of the CR2450 batterymaterial system; the third is the Internet of Things technology to improve the safety of power batteries; the fourth is the acceleration of the industrialization of solid-state batteries.

　　Compared with traditional CR2450 batterypacks, the emergence of new CR2450 batterypack technologies shows that the current power CR2450 batterymarket is moving from previous tradition to innovation, from chaos and complexity to orderly concentration, and from policy promotion to market orientation.

　　At the same time, new CR2450 batterytechnologies also reflect the technological gap between CR2450 batterycompanies, which may accelerate industry reshuffle and further increase market concentration.

　　In addition, OEMs are constantly exerting their influence on the development of power CR2450 batterytechnology, and the demand for forward development of complete vehicles has become increasingly obvious, thus having a positive impact on the development of CR2450 batterytechnology.

　　However, the emergence of new technologies also comes with certain risks. As OEMs have higher and higher requirements for CR2450 batteryperformance and cost reduction, CR2450 batterycompanies must be more cautious in accelerating the development and commercialization of new CR2450 batterytechnologies, otherwise they may "get burned" due to the lack of sufficient verification of radical technologies.

　　Industry insiders believe that as subsidies recede in 2020, the technical solutions of Japanese and Korean CR2450 batterycompanies will gradually penetrate into the country. OEMs are also developing new CR2450 batterytechnologies. In the future, power CR2450 batterytechnology will present diversified competition, and some technologically advanced batteries will Enterprises will have a more competitive advantage.
