china\'s lithium-ion battery industry - solving safety concerns
There are many aspects of Li.
The safety of ion batteries throughout the design process, including safe battery structure, safe raw materials, protective functions and safety certification.
Mr. Su Jinran, deputy chief engineer of Tianjin Lishen Battery Co. , Ltd. , said in an interview with China electronic news that product safety began with product design, so he chose the appropriate electrode material, the primary task of safety battery design is separator and electrolyte.
For battery negative materials, ternary materials that are widely used in battery design and produce satisfactory performance-manganese lithium and lithium iron phosphate are safer than traditional cobalt lithium and nickel lithium.
Su said that at present, sufficient scale has been established in the research and development and manufacturing of anode, cathode and electrolyte materials in China, which can basically meet Li-ion batteries.
In addition, research on some safety coating materials has begun to be commercialized, providing a new aspect for improving coating materials
However, China needs more investment and follow-up in research and development and application in this area.
Sanyo Motor Company, a senior manager of mobile energy business
China limited commented that when it comes to Li-
Ion batteries, which play an important role in the manufacture of all components and materials of batteries.
So they try to assemble the parts and materials together to ensure overall safety.
In addition, in order to utilize parts and materials, it is important to adopt advanced industrial production technology and quality control technology when considering safety improvement.
\"Further ensure Li
For the safety of ion batteries, we need to consider the batteries together and the electronic devices that use them.
At the same time, electronics manufacturers and battery manufacturers must work together to solve the problem of battery safety.
The executive said. Innovation-
Due to the complexity of Li-, based on standard settings
The safety mechanism of ion batteries, especially the impact on safety after recharging
Use the battery to understand the process of Li-
The safety of ion batteries and the formulation of standards should be gradual.
At the same time, we should also consider the development and application of external control technology.
Su suggested that it be established-
The ion battery safety standard is a highly technical work, and the standard setting professionals of the battery standardized organization and technical experts in the battery industry, users and electronic control fields should all be involved in this process, including experimental verification work.
Mr. sun chuanhao, senior engineer of China Institute of Electronic Standards, said,
At present, ion batteries can be divided into energy and power types.
Since these two products differ in material and design structure, their test methods and requirements are different even under the same safety conditions. The so-
It is called portable battery which belongs to the type of energy, including Li-
Ion batteries for mobile phones, laptops, digital cameras and cameras, while power-type batteries for power tools, electric bicycles and electric vehicles.
Sun suggested that authorities should introduce them separately.
These two different types of ion battery safety standards.
Many industry experts agree that the development of standards
Ion batteries in China should be based on independent innovation, and also need to learn from international standards such as IEC, IEEE, UL and so on. Li-
Due to its light weight and high energy density, the ion battery used for vehicles, Li-
The application of ion batteries in China is expanding.
Ion technology can be used heavily in hybrid and electric vehicles, which will further increase the Li-
Market penetration rate of ion batteries.
Therefore, the development of Li-
Ion batteries for cars have become the focus of many Chinese people.
Ion battery manufacturers
Huang Xuejie, an analyst at the Chinese Academy of Sciences, pointed out that although China is now the second largest in the world
The ion-making country, which is only behind Japan, is not yet a strong country in this field. Many small-
Domestic size batteries are still produced manually, with uneven product quality and fierce price competition.
In China, the commercial of power batteries is still in the early stage-
Ion batteries that can be used for 15 years on hybrid cars, as well as their key materials and technologies.
Because there are high technical barriers to the production of high-end products such as automobilesuse Li-
Experts called for cooperation between R & D, engineering and management experts.
At the same time, in order to improve the technical level of China\'s battery industry, the government should also help to establish a professional knowledge dissemination mechanism for the battery industry.
