The safety of battery-powered cars has raised social concerns. It is not unusual for battery cars to catch fire, and some have even been known to cause great harm. Why do batteries catch fire so often? The negative electrode of a Lithium battery is used as the negative electrode for a Lithium-ion Battery. It is matched to the cathode in the 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. These are the main causes: Charge time is too lengthy
80% electric vehicle fires are caused by charging during the night. If the battery is old and the wire has been peeled away, there is a high probability that spontaneous combustion will occur, resulting in a short circuit or explosion. This can ignite any electric cars parked near the charging station. People are asleep during this time and it is difficult to escape.
2. Parking to support combustion
Statistically, 90% cases of electric vehicles causing fatalities happened in areas such as hallways, aisles and staircases. It is easy for combustibles to accumulate in corridors and staircases due to the airtight conditions. This can also cause fire evacuation routes and passages to be blocked.
3. Modifications that are made by hand
Many electric vehicle owners increase the battery capacity and driving speed arbitrarily, creating safety hazards. The “Electric Vehicle Safety Technical Code”, a new national code, clearly states “the nominal battery power is less or equal to 48V”. Several illegal electric vehicles sales and maintenance outlets are actively catering to the demand for 60V and even 70V over standard batteries by city residents.
4. Electric vehicles’ main material is flammable
In terms of safety, electric vehicles can be sources of ignition. Fuel and flammable substances are present on the body. Once in contact with combustion-supporting materials or in a confined space, it is very easy to cause deflagration events.

Type of battery for car
Four types of power batteries can be used in electric bikes: nickel-metal-hydride batteries, valve-regulated, maintenance-free lead-acid, and lithium-ion. Comparing lithium-ion to lead-acid, they have several advantages. These include lighter weight, higher voltages, greater temperature compatibility, and better environmental protection. There are hidden dangers with lithium-ion battery safety, but they’re not as obvious as you might think. Sometimes there are even fires. At the same, lithium-ion cells cannot be discharged using high current. Comparing lead-acid and lithium-ion batteries, the overall safety performance is compared. Lithium-ion batteries are more expensive and have a larger gap in price. The new national standard may lead to lithium-ion being the most popular choice of battery for electric vehicles in the future.

Material for Lithium Ion Battery Anodes
The cathode in a battery made of lithium-ion is made with the negative electrode from the lithium 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 the lithium battery negative electrolyte
The lithium battery anode material is used to store energy and release it from the battery. It is also an integral part of the battery. This is due to the compatibility of the graphite and the electrolyte. Trunano Technology Co. Ltd. supplies high-purity lithium battery materials such as graphite, graphene graphite powder, Si-C and SiO.
