80% of electric vehicle fires occur during the charging process at night. If the battery is aging and the wire is peeled off, spontaneous combustion, short circuit and explosion are very likely to occur during charging and ignite the electric car parked nearby. During this time people are asleep and there is almost no time to escape.
2. Parking position to support combustion
According to statistics, 90% of the cases of electric vehicle fires causing casualties occurred in places such as halls, aisles and stairwells. The airtight environment in the corridors and stairs is easy to pile up combustible materials, and it will also block fire evacuation passages.
3. Man-made modification
Many electric car owners arbitrarily increase battery capacity and increase driving speed, causing safety hazards. The new national “Electric Vehicle Safety Technical Code” clearly stipulates that “the nominal battery voltage is less than or equal to 48V”. Some illegal electric vehicle sales and maintenance outlets actively cater to the demand and illegally install 60V or even 70V over-standard batteries forcity resident.
4. The main material of electric vehicles is flammable
From the perspective of hazards, electric vehicles themselves are sources of ignition. There are fuel and flammable materials on the body. Once in contact with combustion-supporting materials or in a confined space, it is very easy to cause deflagration events.
Battery car battery type
There are four types of power batteries that can be used by electric bicycles, namely valve-regulated lead-acid maintenance-free batteries, colloidal lead-acid batteries, nickel-metal hydride batteries and lithium-ion batteries. Compared with lead-acid batteries, lithium-ion batteries have many advantages, such as lighter weight, more charge and discharge cycles, high rated voltage, high temperature applicability, and environmental protection. However, as far as the current market situation is concerned, there are certain hidden dangers in the safety of lithium-ion batteries. Sometimes there are fires. At the same time, lithium-ion batteries cannot be discharged with high current. The overall speed and safety performance are compared with lead-acid batteries. There is a big gap between batteries, and the overall price of lithium-ion batteries is higher than that of lead-acid batteries. However, with the implementation of the new national standard, lithium-ion batteries may become the first choice for electric vehicle batteries in the future.
Lithium-ion battery anode material
The negative electrode material of the lithium battery is the negative electrode in a lithium-ion battery and is matched with the cathode material in a lithium-ion battery. The anode materials in lithium-ion batteries act as the host, and they reversibly allow lithium ions to intercalate/deintercalation during charge/discharge cycles.
Application of lithium battery negative electrode
Lithium battery anode materials are used to store and release battery energy and are also an important part of the battery. The compatibility between the graphite anode and the electrolyte is better, and it is also the improvement of the battery performance. Trunano Technology Co., Ltd. provides high-purity and ultra-fine lithium battery anode materials, such as silicon powder, Si-C, SiO, graphite, graphene, etc.
