Empirically, we study the new energy vehicle battery (NEVB) industry in China since the early 2000s. In the case of China''s NEVB industry, an increasingly strong and complicated coevolutionary relationship between the focal TIS and relevant policies at different levels of abstraction can be observed. Overall, we argue that more research is needed to
Energy Technology is an applied energy journal covering technical aspects of energy process engineering, including generation, conversion, storage, & distribution. Herein, a detailed correlation index of health indicators for lithium-ion batteries is presented.

As one of the core technologies of NEVs, power battery accounts for over 30% of the cost of NEVs, directly determines the development level and direction of NEVs. In 2020, the installed capacity of NEV batteries in China reached 63.3 GWh, and the market size reached 61.184 billion RMB, gaining support from many governments.
The battery industry is market-driven, and the lack of understanding of the market demand can only cause these small and medium-sized power battery enterprises to suffer a fatal blow and withdraw from the market. At the same time, the existence of these enterprises also disrupts the market order of the entire battery industry .
In recent years, the explosive development of NEVs has led to increasing demand for NEV batteries, which has led to the rapid development of the NEV battery industry, resulting in increasing prices of raw materials manufactured and sold by raw material manufacturers, i.e., the upstream battery industry.
As a core component of NEVs, the battery itself is market-driven by policies, and the lack of continuity in supporting policies will leave the NEV battery industry without supporting policies in the long run, which may slow down the development of the whole industry.
