How does BYD strive to seize the opportunity of industrialization of solid-state lithium-ion batteries?

A few days ago, the research team of the "Change 2018 Exploring the Future Pattern of Power Battery" conducted by China Power and Physical Power Industry Association Power Battery Application Branch and Battery China Network came to Shenzhen BYD Co., Ltd. (hereinafter referred to as "BYD") Chunyu Zhang, Director of the Second Business Unit of BYD Battery Group, and Huaying Huang, Head of QAD Product Safety Promotion Section, have conducted in-depth exchanges and discussions on issues such as the development of the power battery industry.

At present, BYD's power battery is mainly used internally by the Group. With the separation of the battery business, BYD's power battery products will be more in the future. In addition, BYD's battery products are also widely used in foreign special vehicles and foreign energy storage. BYD has been deeply involved in the lithium battery industry for many years and has accumulated excellent lithium battery manufacturing technology. With its solid product quality, BYD is confident to occupy a broader lithium battery market in the future.

Ms. Chunxi Zhang told Battery China that the current technical route of BYD's power battery is mainly lithium iron phosphate battery and ternary battery. Compared with liquid batteries, the safety of solid-state batteries is more secure. BYD has always paid attention to the safety of terminal products, and has begun to develop related research and development work on solid-state batteries. At present, the company is actively promoting the R&D and deployment of next-generation lithium batteries, and taking solid-state batteries as the next step of research and development, and actively promoting the industrialized R&D and application of related products.

Understand, according to research group to meet the market demand of pure electric passenger cars at present stage, BYD rapid response on the layout of the li-ion battery products, by the end of 2017 has been built with 16 GWH capacity of power battery production line. In addition, BYD base in Qinghai, a total of 24 GWH ternary production line is under construction. Affected by the upstream raw material prices, power battery industry margins decline, at the same time it also for car companies to develop new energy vehicles has done a lot of obstacles raw material supply.

BYD is a representative of the deep integration of the domestic automobile industry and the lithium battery industry. Regarding industrial development issues, Ms. Chunxi Zhang believes that the future competition between new energy vehicles and traditional vehicles must be market-oriented, the cruising range of new energy vehicles and the fast charging of batteries. Performance and the price of the vehicle must be competitive and must be recognized by the end consumer. Although the battery core is the core component of the new energy vehicle, it plays a vital role in the market competitiveness of the vehicle. However, the industry colleagues must also realize that the performance improvement of the battery core has limits. From the perspective of the battery core, by increasing the energy density, the vehicle's cruising range is deliberately improved, and the energy-saving design of the vehicle is neglected. This product is far from meeting the needs of the end consumers, and may even lead to safety risks during the use of the vehicle. Industrial development must return to the market, produce new energy vehicles that truly satisfy the end consumers, and assemble a comprehensive cost-effective battery product recognized by consumers.

The person in charge of the research activity, the Secretary-General of the Power Battery Application Branch, Yu Zhang, CEO of Battery China Network, and Bo Zhou, Director of the Standardization Department of the Power Battery Application Division/Industry Research Department, participated in the discussion. The research team also visited the BYD Shenzhen Industrial Park and exchanged views with the relevant person in charge of BYD on the company's relevant work experience on Pack light weighting, battery ladder utilization and production standard management.
