Why do battery cars catch fire frequently in summer

Battery cars have brought convenience to most residents, but the safety of battery cars has aroused social concern. Fires on battery cars are not uncommon and even caused great harm to unfortunate participants. Why do battery cars catch fire frequently? 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. The reasons for the largest concentration among them are as follows: 1. Charging time is too long
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.

Determinants of the Performance of Lithium Battery Negative Electrodes

Work Principle and Composition of the Lithium Battery The lithium-ion secondary battery, is rechargeable and can be used to charge a variety of devices. It primarily consists five major parts: current collector, initial, continuous. continuous. twisted. alternating.

It is important that lithium ions are more easily extracted/inserted in order to achieve the charge and discharge functions.

Through the electrolyte, lithium ions can be extracted from the electrode material to charge it. While electrons are flowing out of the positive electrode material through an external circuit, they flow to the opposite electrode. After the lithium battery has been discharged, lithium-ions are taken from the negatively charged electrode and embedded through the electrolyte. The external circuit allows electrons to flow through the material of the positive electrode.

What's the Anode Material for Lithium Battery?

Negative electrode materials are the carriers of lithium ions, electrons during the battery charging process and play the function of energy storage or release. It plays a vital role in power battery safety and performance.

An ideal material for negative electrodes must meet at least these 7 conditions

1. This low chemical potential creates large potential differences with the cathode, creating a high power battery. 2. It must have a larger specific cycle capacity. 3. Li+ should be easy to insert into the material that is negative and then extracted. This will allow for a stable charge and discharge potential during extraction. 4. It exhibits good electronic conductivity as well as ion conductivity. 5. It's stable, and it is compatible with some other minerals. 6. Materials should have a rich source, be inexpensive, and easy to make. 7. You can be sure that your home is clean, safe and green.

It is rare to find anode materials that fulfill the requirements above. This makes it a difficult task for researchers in lithium battery research to develop new materials.

What does an ideal Anode Material look like?

The first is that it features a low discharge platform. This allows for a range of positive electromaterials to combine with it and form secondary batteries with high discharge voltages. This keeps many materials from the door. Second, it has a much porous structure which can hold lithium ions. The molecular weight is also very small. This does not just depend on the material type, but also its physical structure. The difference between carbon and silicon materials is not negligible. If the technology means can be developed sufficiently high to allow manipulation of both the molecular structure and the atomic structures, then the structure will have greater importance than the atomic one. It is also important to consider the chemical stability, structural stability, and stability. This affects battery safety and battery life. This requirement means that the safety of the battery must be the first priority. Materials should be easily available, or in other words, cheap. While many of the new products will initially be costly, as production increases, so does the cost to produce them. It is best to use the graphite-anode lithium batteries. Advanc3dmaterials (aka.
