Application of Lithium Batteries in Electric Vehicles

Lithium batteries are widely used, and because of their unique performance advantages, they have been widely used in the electronic age, such as notebook computers, cameras, mobile phones and so on. The emergence of the new energy vehicle industry has greatly promoted the development of lithium batteries, opening up broad prospects for the application of lithium batteries. 
If the lithium battery for electric vehicles is regarded as a dish, then some ingredients and ingredients are needed to complete this dish. These ingredients are positive electrode materials, negative electrode materials, electrolytes, isolation materials and battery management systems.
Opportunities and Forecasts
1. Due to the possibility of safety management and control in the above analysis, real-time monitoring of low-speed electric vehicles may be more thorough than that of new energy vehicles; local monitoring platforms will become the main platform for low-speed electric vehicle safety monitoring.
2. Lithium-iron batteries are currently mainly used in commercial vehicles and some special-purpose vehicles. As the commercial vehicle market gradually becomes saturated in the next few years, and the logistics vehicle market pursues higher specific energy and energy density indicators, the sales of iron-lithium batteries will increase. It is difficult to achieve double-speed growth. In the future, as the competitive landscape becomes clear, there will be iron-lithium battery companies focusing on low-speed electric vehicles. However, the regional development pattern of low-speed electric vehicles may lead to the emergence of local protectionism.
3. The lithium electrification of low-speed electric vehicles is carried out under the condition of low-cost battery system, and safety is an unavoidable factor. To achieve cost control and safety assurance, power battery companies must first increase the production capacity, and then use the B-type cells after grouping performance parameters in the lithium-ion battery system for low-speed electric vehicles, so as to obtain the driving force for price exploration.
4. In the process of lithium electrification of low-speed electric vehicles, lithium battery companies and low-speed electric vehicle companies are more likely to form new partnerships, and more likely to form alliances and even acquisitions. The variables in this field are particularly large.
Safety Issues of Lithium Batteries
Looking at the problem from the worst situation, according to the "New Energy Vehicle Fire Fighting and Rescue Regulations" issued by the Ministry of Public Security, due to some characteristics of lithium batteries, road fire fighting and rescue also have new characteristics.
If the low-speed electric vehicle cuts into the lithium battery system at once according to the requirements, we must consider the following issues:

1. Compared with existing new energy vehicles, will the frequency of accidents increase? This comparison is mainly based on several comparisons: the quantity base of the low-speed electric vehicle itself, strict cost constraints and the time issue of new introduction;

2. Will the existing market demand, the time required for the entire compliance process, and the short follow-up time increase the risk? Many accidents have occurred in the development process of new energy vehicles. Car companies have matured through accident trial and error and problem improvement, and they have a relatively long time to implement development and system safety verification.

3. The market of low-speed electric vehicles is characterized by the fragmentation of the private market. If the first two items are not in place, it may lead to secondary accidents after the spontaneous combustion of low-speed electric vehicles, which will bring disaster to houses or other parked vehicles.
