“…A lithium battery can be classified into three categories, based on its electrolyte state: a liquid lithium battery, a semisolid lithium battery, and a solid lithium-ion battery. With the increase in the degree of solidification of the electrolyte of lithium-ion batteries, the safety of lithium-ion batteries is also higher, but the technical difficulty and manufacturing costs are also higher [2]. Currently, the majority of electric cars are powered by lithium-ion batteries because to its high specific energy, long cycle life, and low self-discharge rate [3].…”

People are benefiting from technological advancements as society develops and advances, but the energy crisis is getting worse, making the creation of new energy vehicles one of the most important areas of research at the moment. New energy vehicles are also favored by more countries because of their low consumption. But at the same time, new energy vehicles still have many problems in battery safety, charging efficiency, etc. Based on this, the facts in this study are collected and analyzed on the battery issue with new energy cars. Propose reliable methods and strategies to promote the development of new energy vehicles in a better direction. It is envisaged that this will encourage the use of batteries in the future and the adoption of electric vehicles more generally. It is hoped to provide reference and new ideas for the improvement of the performance of new energy vehicles and the direction of future development.

“…Compared with China's new energy vehicle sales in 2018, the market share of new energy vehicles is still not large enough. The reasons why users do not accept new energy vehicles are low cruising range and long charging time [2]. The service life for a power battery in the EV is about 8 years due to degradation in capacity.…”

This paper investigates the new energy vehicle industry. Under the problem of environmental pollution, China considers the new energy vehicle industry as an important sector. The Chinese government has heavily subsidized the industry and introduced many policies. Although the COVID-19 epidemic has had a serious impact on the world's economy, China's economy has maintained growth, providing a certain guarantee for the development of the new energy vehicle industry. Then we calculated the carbon emissions of traditional fuel vehicles and compared them with new energy vehicles. Then we analyzed the existing technologies in the industry and summarized two questions. Such as range issues and safety issues. And we discussed the reason why it happened and find the solution below, such as improving the battery quality and so on. Also, this paper looked forward to the future of new energy vehicles and we think the development prospects are very broad both in terms of environmental protection and economy.

“…With the shortage of fossil energy and the enhancement of environmental protection awareness, all countries in the world are vigorously developing new energy industries. [1][2][3] As a sustainable storage element of new-generation energy, the lithium-ion (Li-ion) battery is widely used in electronic products and electric vehicles (EVs) owing to its advantages of high specific energy, long cycle life, low selfdischarge rate, no memory, and low emissions. [4][5][6] However, the Li-ion battery is sensitive to temperature variation, the optimal working temperature range is 20-50°C with a temperature distribution of less than 5°C.…”

A reliable battery thermal management system (BTMS) not only can effectively decrease the maximum temperature but also maintain the temperature uniformity of the lithium-ion (Li-ion) battery after grouping. Nevertheless, considering the deficiency of a single heat dissipation method, there exist challenges in efficient heat dissipation structure design, especially at high discharge rates. In this work, a composite heat dissipation structure of battery module with phase change material (PCM)-aluminum plate-fin is proposed. Meanwhile, the transient effects of different discharge rates, melting points, and thickness of PCM on the thermal characteristics of the module are analyzed. Results show that the maximum temperature of the module with PCM-aluminum plate-fin can be reduced by 25.8°C, 11.0°C, and 10.2°C respectively at 4 C discharge rate compared with natural convection, aluminum plate-fin, and paraffin PCM, and the maximum experimental error among them is less than 5%. During 2-5 C discharging, the melting rate of phase change increases first and then decreases, which leads to the trend of the maximum temperature and maximum temperature difference of the module rising with bending twice. When the ambient temperature is 25°C, the paraffin PCM with a melting point of 28°C is implemented for battery cooling because of its more rapid melting and heat absorption. The increase in PCM thickness is beneficial to the heat dissipation of the module. The optimal PCM thickness of 3 mm can realize temperature uniformity control within 2.5°C.
