Why Are Lithium Polymer Batteries Dangerous? — Lifepo4 Battery For Ride-On Car

From:CTECHI GROUP Limited     Release time:2018-09-30

Overview:Apple is investigating the cause of a burning iPhone 6 Plus charged by a female user in Palm Harbor, Florida. This is not the first time an Apple phone has ever had a safety accident. In late January, Samsung also released the results of the Note 7 battery explosion investigation. The problem is still in the battery, because the SDI and ATL batteries provided by the causes of spontaneous combustion are different, so Samsung recalled the phone and replaced the battery re-listed. The explosion problem still remains unsolved. Earlier, Tesla car, Boeing 787 passenger aircraft, BYD electric taxi also have similar problems.

In late January, Samsung also released the results of the Note 7 battery explosion investigation. The problem is still in the battery, because the SDI and ATL batteries provided by the causes of spontaneous combustion are different, so Samsung recalled the phone and replaced the battery re-listed. The explosion problem still remains unsolved. Earlier, Tesla car, Boeing 787 passenger aircraft, BYD electric taxi also have similar problems. 

All of these seem to have a connection with cell phone batteries to insecurity, but people can't live without it. Lithium batteries are now widely used as an energy storage tool, such as commercial lithium ion battery for ebikes, lithium polymer battery for mobile phones, lifepo4 battery for ride-on car and li-polymer battery for smartwatch. Why are there frequent safety incidents in the near future, and what is the future direction of battery development?

Lithium battery working environment

Increasingly "bad"

Large screen, large memory and high-speed processors have become the standard of smart phones nowadays. But bigger and bigger screens and higher main frequency multicore processors are big consumers. Samsung Note 7, for example, has a 4-core processor with a main frequency of 2.15GHz and a operational memory of 4GB, which is roughly equal to the performance of the mainstream notebook computers on the market. It also has to deal with information communication while maintaining standby, which shows how much pressure is on the battery.

How to increase standby time? Under the premise of constant power consumption, increasing battery capacity seems to be the only way. Unlike Tesla's 18650 batteries, lithium polymer battery for mobile phones are also widely used in electronics, which are thin, soft-surfaced, bulk batteries. Lithium polymer batteries are "vulnerable" because they are not protected by hard shells. Over-pressing, overheating, internal or external piercing can put them at risk of ignition and explosion.

Commercial Lithium Ion Battery For Ebikes

Samsung released the results of a formal investigation into the Note 7 explosion on January 23, saying the first batteries suffered crushing damage in the upper right corner, in line with previous third-party reports that the size of the batteries did not match the battery bin; the second batteries suffered from "positive welding burrs, piercing electricity." The pool causes short circuit fire. These two points are precisely the "gate of life" of lithium polymer batteries.

Not only that, more and more electronic devices appear on the "fast charge" technology has also increased the burden on the battery. Because the current and voltage of fast charging are much higher than that of ordinary charging state, it can not be ruled out that there is a certain probability that some dangerous accidents will occur when the power management module fails. At the same time, frequent use of fast charging will shorten the battery life.
