Thermal runaway temperature of ternary lithium battery

Ternary lithium batteryThe thermal runaway temperature is approximately 200 degrees.

The thermal runaway temperature of ternary lithium batteries is essentially around 200 degrees. Regarding the spontaneous combustion incidents of new energy vehicles, most of them are ternary lithium batteries. Therefore, for hot areas, the risk of spontaneous combustion of ternary lithium batteries is higher.

Ternary polymer lithium batteries refer to lithium batteries that use lithium-nickel-cobalt-manganese or lithium-nickel-cobalt aluminate as the cathode material. There are many types of cathode materials for lithium-ion batteries, mainly lithium-cobalt acid oxide. , lithium manganate, lithium nickelate, ternary materials, lithium iron phosphate, etc.

What is the max temperatureimal what can lithium batteries withstand?

Working temperature range of 18650 lithium battery

Overcharge temperature range: 0℃—+60℃, charging temperature: 0℃—+45℃, temperature operating temperature: -20℃-50℃, the best operating temperature is 20℃-40℃, 60℃ is the temperature to ensure battery life, high temperature will shorten the life, higher temperature at 100℃ will be dangerous, generally 140℃ will burn or explode.

The temperature limit of general mobile phone lithium batteries is 40 degrees Celsius, 40-60 degrees Celsius. If the time is not too long, there will be no problem. Lithium batteries can also be specially customized to withstand high temperatures, and their high temperature performance will be much better.

The temperature limit set for lithium batteries of tcell phones is generally 40 to 60 degrees. Batteries are generally marked with explosion-proof valves, and high temperature resistant lithium batteries can withstand temperatures of up to 800 degrees. Generally, lithium batteries are tested to withstand high temperatures of 200 degrees, 500 degrees and 800 degrees, but they are generally not exposed to such high temperatures in daily life.

For lithium batteries, there is currently no clear theory in the industry to support the inevitable relationship between internal resistance, discharge platform, life, capacity, etc. under various temperature performance. Calculation formulas and relevant mathematical models. are still under study. Generally speaking, lithium batteries are not sensitive to temperatures between 0 and 40°C. However, once the temperatureexceeds this range, service life and capacity will be compromised.

In order to ensure the lifespan, safety and reliability of lithium batteries, advanced protection management systems are used in high temperature resistant lithium battery packs to prevent overcharging , overdischarge, high temperature operation and low temperature. temperature charging or short circuit be damaged or even cause safety problems.

Detailed information:

Be sure to pay attention to the following points when 'purchase.

1. Is the capacity clearly marked? Batteries without clearly marked capacity (such as 1000 mAh or 1000 mAh) are most likely using lower quality batteries or recycled batteries. Many inexpensive batteries on the market are made from recycled batterieses. Although they are cheap, their lifespan is short and their unstable quality can damage the phone.

2. Is there a guaranteed standby time? Standby time is the duration of continuous use from the time the battery is installed in the phone until the next charge. Generally, batteries sold in the market cannot guarantee standby time to customers. This is because the battery quality is unstable. Many cheap batteries use poor quality battery cores, so the standby time is very short.

3. Whether to install a safety protection circuit board. Without a protective circuit board, the lithium battery may deform, leak and explode. Facing fierce competition in price reduction, each company is looking for cheaper protection circuit boards, or even omitting this device, leaving the marketflooded with lithium batteries that are at risk of exploding. Consumers cannot determine whether there is a protective circuit board from its appearance, so it is better to choose a reputable trader to purchase it.
