At the beginning of the year, a fire incident once again aroused social concern. In the early hours of February 8, a fire broke out in Four Villages, Yichuan, Putuo District, Shanghai, killing three people.
Shanghai Putuo Fire Department initially identified the cause of the fire as the resident put the electric bicycle lithium-ion battery in the bedroom, the battery failure caused the fire, after preliminary identification, the lithium battery output voltage that caused the fire exceeded 60 volts, which is a typical over-standard battery.
Some time ago, CCTV-10 "Experimental Scene" column group in the China Electronics Technology Standardization Institute, to find professional and technical experts to interpret the safety of lithium batteries, and selected good and bad lithium battery samples for comparative experiments, exposing the secret of inferior lithium battery deflagration.
Since the implementation of the new national standard, the problem of lithium batteries for electric vehicles has attracted much social attention, only because of the frequent occurrence of safety problems and repeatedly involving human lives. In this Shanghai fire incident, the Shanghai Municipal People's Congress deputies who participated in the law enforcement inspection said that they had investigated many places and found that many battery car batteries were recycled by illegal businesses after they were used. After being put into the market, it is used for the second time, which leaves a great hidden danger.
He suggested that the state should upgrade the lithium battery for electric bicycles from a recommended standard to a national mandatory standard, and modify the relevant standards according to new materials, new processes, and new characteristics. At the same time, cut off the supply and illegal modification of lithium batteries for electric bicycles from the source, clarify the main body of law enforcement, and improve the comprehensive law enforcement mechanism.
It is urgent to solve the safety problem of lithium batteries in electric vehicles, and the three keywords of the lithium battery market in 2022 must be understood.
First, safety
Safety is the first and most critical requirement for lithium batteries. Any battery brand, vehicle brand, if you do not put the safety of lithium batteries in the first place, is irresponsible to the consumer market and society.
From the rise of lithium batteries after the new national standard, to many consumers talk about lithium discoloration, the reason why lithium batteries are now attracting much attention and being colored glasses is that many manufacturers ignore safety issues.
Some relevant technical experts said that in 2018, the decommissioned lithium batteries of new energy vehicles can reach 1.1 billion watt-hours. In this process, there will be partially retired and eliminated batteries, through some small manufacturers, into the field of electric bicycles. This part of the eliminated lithium batteries, and even many of them may currently be used by electric vehicle users, there are huge hidden dangers.
Thinking backwards, if manufacturers can do a good job in safety issues, they are bound to be able to seize the new national standard market faster and better.
Second, cost control
In 2021, the raw material cost of lithium batteries will begin to increase explosively. CCTV Finance reported on the problem of lithium battery raw materials last year, the price of upstream raw materials has repeatedly reached new highs, lithium carbonate, lithium hydroxide and other cathode materials as the most critical cathode materials for lithium batteries have risen, and some prices have increased by 200% compared with the beginning of last year.
At the beginning of this year, battery-grade lithium carbonate rose by 10,000 yuan / ton, with an average price of 400,000 yuan / ton; lithium hydroxide rose by 9,500-10,500 yuan / ton, more than double the price at the beginning of last year.
In 2022, in addition to the necessary safety issues, major battery factories and vehicle manufacturers must also respond to the cost of lithium batteries, and win the cost war in the context of the soaring raw materials.
3. Recycling
When it comes to the soaring problem of raw materials, it is necessary to mention the recycling of lithium batteries.
The recycling of lithium batteries is also an urgent event, which also includes the "Interim Measures for the Management of The Recycling and Utilization of New Energy Vehicle Power Batteries", "Coding Rules for Automotive Power Batteries", "Specifications and Sizes of Power Batteries for Electric Vehicles", "Specifications for Recycling and Dismantling of Vehicle Power Batteries" and "Waste Energy Detection for Vehicle Power Batteries".
Under the rapid development of new energy vehicles and the vigorous promotion of the new national standard for electric vehicles, the use of lithium batteries has been popularized on a large scale, so the recycling of lithium batteries must be a big outlet in the future market, and it is also an important factor to solve the large-scale inflow of inferior waste lithium batteries into the market.
The harm of inferior lithium batteries has greatly affected the social image of the electric vehicle industry, and it is also an important issue that the entire industry should strive for, and it is hoped that the lithium battery market in 2022 can be significantly improved.
