[PDF Version]With the advancement of China's lithium battery and new energy vehicle production technology, China will contribute more lithium battery raw materials, materials, lithium batteries, and new energy vehicles to the world in the future, which will further increase the supply and demand pressure of lithium resources in the new energy industry.
The industry of lithium-based new energy is defined as a strategic emerging industry in China. In 2022, China's lithium battery exports amounted to nearly CNY 342.7 billion. China's lithium-ion battery shipments reached a total of 660.8 GWh in 2022, accounting for over 60% of the global market share.

With the large-scale application of new energy vehicles (such as electric vehicles) and smart grids, the limited lithium resources and their uneven geographical distribution in China have become the main bottlenecks in the development of lithium-based new energy industries in the country.
China's lithium-based new energy industry also has some disadvantages, and one of the most prominent of these is its lithium resource bottleneck. The lithium-based new energy industry is a system of major components, such as lithium mining, linked together in an intimate and interdependent relationship.
In 2019, China passed lithium raw materials, lithium battery materials, lithium batteries, and the total net outflow of lithium from new energy vehicles is about 11.669 thousand tons, while the domestic consumption of lithium produced by new energy vehicles in 2019 is only 9.06 thousand tons.

Researchers in China lead the world in publishing widely cited papers in 52 of 64 critical technologies, recent calculations by the Australian Strategic Policy Institute reveal. China's advances in battery research have helped it gain a dominant position in electric vehicles. Gilles Sabrié for The New York Times
Regarding knowledge development and exchange (F2 and F3), Chinese battery enterprises have increased their R&D expenditure, leading to several technological breakthroughs as well as increasing domesticalization of the key technologies in the four core battery components (anodes, cathodes, electrolytes, and separators) (Gov.cn, 2020).
And because of the protection, as well as the efforts to domesticalise the battery value chain, the huge Chinese market was effectively restricted to domestic firms, and hence they could invest more in R&D and technology development and capture more added value (F2, F3).
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.
Even the progress is sluggish, under the incentives of national governments, researches on the design of advanced materials, the fabrication of new electrodes, the optimization of battery engineering etc. have never been ceasing, trying to push the boundaries of energy density, power density, cycle life, cost and safety.
Due to the very generous subsidy scheme, many of the Chinese car and battery manufacturers increasingly shifted their focus to meeting the subsidy criteria required by the policy, instead of concentrating on product and process innovations that would guarantee their market success in the long run (Intermediary 3, Expert 4).
This paper investigates the specific features, advantages and dependencies of connecting battery cells by resistance spot, ultrasonic and laser beam welding.
Different welding processes are used depending on the design and requirements of each battery pack or module. Joints are also made to join the internal anode and cathode foils of battery cells, with ultrasonic welding (UW) being the preferred method for pouch cells.
Brass (CuZn37) test samples are used for the quantitative comparison of the welding techniques, as this metal can be processed by all three welding techniques. At the end of the presented work, the suitability of resistance spot, ultrasonic and laser beam welding for connecting battery cells is evaluated.
This means that, on the one hand, there may be accessibility issues as the testing is performed on already assembled modules or packs, and on the other hand, key performance indicators for battery welding applications, such as electrical and fatigue performance of the joints, are not served.
Moreover, the high-volume production requirements, meaning the high number of joints per module/BP, increase the absolute number of defects. The first part of this study focuses on associating the challenges of welding application in battery assembly with the key performance indicators of the joints.

[PDF Version]To enable flexible deployment and to reduce the cost of operation and maintenance, modular design will become mainstream in the stand-alone PV/B hybrid energy system. Rebecca Lidvall reassembled the PV/B system and introduced a modular integrated energy array invented by Roccor . This module contained PV cells and a solid-state battery.
The LiFePO 4 cell is the most suitable battery for the PV-battery Integrated Module. The use of batteries is indispensable in stand-alone photovoltaic (PV) systems, and the physical integration of a battery pack and a PV panel in one device enables this concept while easing the installation and system scaling.
The stand-alone photovoltaic-battery (PV/B) hybrid energy system has been widely used in off-grid equipment and spacecraft due to its effective utilization of renewable energy. For they are interconnected and distinct from each other, the ground and space stand-alone PV/B hybrid energy systems are compared in this review.
As the capacity and complexity of the stand-alone PV/B energy system increase, the traditional, expert-driven system design will be too costly and complicated. To enable flexible deployment and to reduce the cost of operation and maintenance, modular design will become mainstream in the stand-alone PV/B hybrid energy system.
Lithium batteries are increasingly used to store electrical energy in stand-alone PV/B hybrid energy systems due to their high energy density, long life, and low self-discharge rate , , , .
However, the development of photovoltaic technology evolved extremely rapidly, and PV cells have played an irreplaceable role in green power equipment and spacecraft. The following introduces new research progress focusing on battery technology that can be applied in the terrestrial and aerospace fields ( Table 3 ).

Since the Chinese government set carbon peaking and carbon neutrality goals, the limitations and pollution of traditional energies in the automotive industry have fuelled the development of new energy vehicles (NEVs). As a strategic emerging industry, the NEV industry is booming, and the country will vigorously promote it in the future.
The development of the battery industry is crucial to the development of the whole NEV industry, and many countries have listed battery technologies as key targets for support at a national strategic level, which means that the NEV battery industry as a new industry has stepped on the stage of the development of this era. .
On December 19, 2016, the State Council released the “13th Five-Year Plan for the Development of National Strategic Emerging Industries”, in which the NEV industry was included in the development plan for strategic emerging industries . It shows that batteries, as the power source of NEVs, will be increasingly important.
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.
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.
As the largest developing country, China has been adhering to the spirit of “pursuit of excellence” and has invested a lot of manpower and material resources in science and technology innovation, and the NEV battery industry is just one of the projects. The Chinese government has introduced support policies to develop this industry successively.
As a result, several key enterprises have emerged in each of the battery component fields including Easpring and Ronbay in anodes, Shanshan and BTR in cathodes, Capchem, and Tinci in electrolytes, and Shenzhen Senior and Yunnan Energy New in separators (Industry representative 12).
