China’s Lithium-Ion Battery Industry – Solving Safety Concerns


There are various aspects to liion battery safety during its design procedures, including safe battery building, safe raw materials, protective functions and safety certificates. When interviewed by China Electronics News, Mr Su Jinran, deputy chief engineer of Tianjin Lishen Battery Co Ltd, stated that product safety began in product design, therefore choosing the right electrode substances, separators and electrolytes would be the initial priority for safe battery life design. For battery powered anode substances, ternary materials, manganese lithium and lithium iron phosphate, which have been widely used in battery life style and afforded satisfactory performance, are more stable than traditional lithium cobaltate and nickel lithium.

What’s more, the study on some safe how to manufacture a product in china  materials has begun to be commercialized, providing a brand new aspect for improving li ion battery safety, but China still needs to invest more and follow upon R&D and applications in this field.

They are therefore attempting to construct parts and materials to guarantee its safety in general lot. Furthermore, as a way to work with materials and components, it is necessary to hire high level industrial production technologies and quality control technologies when considering safety improvement. “To ensure Li-ion battery life safety we will need to jointly consider batteries and also the electronics that use them. Meanwhile, the issue of battery safety needs to be addressed by most electronics manufacturers and battery manufacturers together.” Said the executive.

Innovation-based Standard-setting

Due to the sophistication in Li-ion battery safety mechanics, notably the impact on safety after re-using the batteries, even the process of understanding Li-ion battery safety and establishing its standards ought to be slow and innovative. And also the evolution and application of outside control methods should likewise be contemplated. Su implied that as setting Li-ion battery safety standards is an extremely technical job, both standard-setting professionals from battery standardisation bodies and technical specialists from the battery business, electronic and users control areas should participate in the process, including experimental verification works.

Senior scientist in China Electronics Standardization Institute, Mr Sun Chuanhao, stated that jelqing batteries currently may be broken up into energy types and power types. Since these two products have gaps in materials and design structures, their testing methods and requirements are dissimilar, even beneath precisely the identical security conditions. The alleged portable batteries belong into the energy-type, including liion batteries used in mobile phones, laptops, cameras and video cameras, even as the power type battery is for power tools, electric bicycles and electric vehicles. Sun suggested authorities should present different liion battery safety standards for all these two identifying types.

Many industry experts agreed that standard setting of liion battery in China should be built in the foundation of individual invention, but also will need to learn and consult with international standards such as IEC, IEEE and UL.
