Power battery is used in new energy vehicles to provide power for the battery, power battery for the general battery for higher technical requirements, higher requirements on the sustainability of the battery, the current domestic power battery manufacturers everywhere, appeared on the surface of comprehensive development, a good scene.Power battery pack liquid cooling heatsink experts believe that the power battery pack industry will be from everywhere to the polarization of the situation into a period of time, power battery enterprise polarization is significant, bibcock with bibcock pattern is basically determined. Throughout the development of power batteries in China, the battery capacity is expanding rapidly, which leads to the continuous oversupply of lithium batteries in China.From the perspective of quality, there is a lot of low-quality production capacity, but there is still a lack of high-quality production capacity. The concentration degree of power battery industry wil
