The Ministry of Industry and Information Technology "stopped" the use of ternary lithium batteries Battery safety has become the focus

Recently, the Ministry of Industry and Information Technology "stopped" the use of ternary lithium batteries in the field of buses, and the core battery problem in such models has become the focus
of discussion in the industry.
Whether the battery technology of new energy vehicles is safe has become the most concerned issue
for consumers.

On the whole, the process of converting cars from fuel to electric is happening, and very quickly
.
However, all new energy vehicles face the problem
of battery safety.
Judging from many consumer complaints about new energy models, problems such as charging failures and serious power loss are related
to batteries.

At present, the batteries used and explored by new energy vehicles around the world mainly include lithium iron phosphate batteries, ternary lithium batteries, fuel cells, physical batteries and so on
.
According to previous reports, in addition to a small number of enterprises in China that produce ternary lithium batteries, there are hundreds of manufacturers involved in the production of lithium iron phosphate batteries
.
In the international context, ternary lithium batteries have a high market share, and many manufacturers of lithium iron phosphate batteries are preparing to invest in the ternary lithium battery industry
.

However, at this time, the Ministry of Industry and Information Technology "stopped" the ternary lithium battery that was preparing to rise, and the Ministry of Industry and Information Technology will carry out a risk assessment of the ternary lithium battery, and suspend the ternary lithium battery bus from being included in the recommended model directory
for the promotion and application of new energy vehicles before the assessment is completed.
For this action of the Ministry of Industry and Information Technology, the industry has also launched a heated discussion, all batteries must admit their unsafety, on this basis to consider how to do a good job of protection
.
Battery safety is mainly in use, there are many factors, and it is unreasonable
to reject ternary materials alone.

Ouyang Minggao, a professor in the Department of Automotive Engineering of Tsinghua University, also gave his own interpretation, "suspension" does not mean that the country denies the technical route of ternary lithium battery buses, ternary lithium batteries have higher energy and better performance, but the new high-specific energy batteries need to be used
cautiously when entering the market.
The suspension is mainly for high-specific energy ternary lithium battery 12-meter pure electric buses
that have recently entered the market.
This model has a large number of passengers, higher requirements for safety, and it is understandable
to give a certain margin.
But not all ternary lithium batteries are suspended, and suspension does not mean that they are stopped
.
In addition, the industry is also calling for a scientific decision-making process or engineering verification method
for batteries.
