On March 28, the groundbreaking ceremony of the second phase 6GWh project of Yiwei Lithium Energy Soft Pack Power Battery was held in Huizhou.

In the layout of the soft package, Yiwei Lithium Energy has turned on the 'fast forward button'.

On March 28, the groundbreaking ceremony of the second phase of the soft pack power battery project of Yiwei Lithium Energy (300014), a subsidiary of Yiwei Lithium Energy (300014), was held in Zone C of the headquarters of Zhongkai, Huizhou.

Gao Gong Lithium Battery (WeChat public account: weixin-gg-lb) learned on the spot that Yiwei Energy's soft pack power battery project is planned for the second phase: the first-phase capacity design is 3GWh Among them, 1.5GWh was completed and put into production on April 10, 2018, and it is expected to reach the overall capacity scale in the second quarter of this year; the second-phase capacity design is 6GWh, with a total investment of 3 billion yuan, and is expected to be put into operation in June 2020. By then, the total production capacity of Yiwei Energy's soft pack batteries will reach 9GWh.

Different from many domestic battery companies that deploy soft packs, Yiwei Lithium Energy is cooperating with well-known Korean battery companies. As of March 2019, Yiwei Lithium Energy has reached intent orders with many mainstream international car companies. The production capacity of its soft package factory is designed to meet the rapidly growing needs of international customers.

At the groundbreaking ceremony, Liu Jincheng, Chairman of Yiwei Lithium Energy, said: 'Our first factory has begun to supply customers, and the second factory that laid the foundation this time It is also a major international company and the most innovative and dynamic new force in the country. The new energy business has just begun. This is a trillion-level market. Yiwei Lithium Energy will seize every minute and every second to seek technological innovation and build a world-class The quality system and products of the company continue to grow.'

In terms of performance, the design energy density of Yiwei's lithium soft-pack ternary battery is more than 240Wh/kg; the discharge rate is the largest It can reach 4C, and the capacity retention rate can still be close to 100%; the cycle life of the single cell can reach more than 2500 times, and it has excellent low-temperature discharge and rate charging performance; in the overcharge experiment, it also shows good safety .

In addition, the soft-pack battery cell standard module independently developed by Yiwei Lithium Energy has a group efficiency of 85%, and the average energy density of the battery pack can reach more than 150Wh/kg; Using the combination of active and passive heat dissipation, the temperature difference can be controlled within 2 ℃; using a variety of series and parallel combination liquid cooling standard modules, which can well meet the requirements of different design space and power consumption of passenger cars.

Less than a year after the first phase of the soft-pack power battery project was put into production, the second phase of Yiwei Lithium Energy Project has started again. It can be seen that Yiwei Lithium Energy's determination to develop the high-end passenger car market.

According to the data of the Advanced Industry Research Institute (GGII), the total installed power battery capacity reached 7.22GWh from January to February 2019, achieving a year-on-year increase. Among them, the total installed capacity of soft pack batteries is 0.65GWh, accounting for less than 0.1%, but it is the fastest growing battery type, with an increase of 140%.

On the one hand, with the increase in the new energy vehicle market shifting to passenger cars, especially domestic and foreign auto companies have begun to compete for high-endurance models, the demand for soft packages is strong; on the other hand, On the one hand, looking at the production capacity of soft pack power batteries at home and abroad, there are not many batteries that can meet the requirements of high endurance and performance.

This brings opportunities to mainstream domestic power battery companies such as Yiwei Lithium Energy, and it is also the fundamental reason why Yiwei Lithium Energy accelerates the deployment of soft package production capacity.

Yiwei Lithium Energy stated that from a technical point of view, after the above-mentioned projects are put into production, it means that the company has won the recognition of world-class car companies in terms of technology and Ru0026D capabilities; From a market perspective, considering that the current domestic production capacity of soft pack batteries is seriously insufficient, once the company starts mass shipments, its market share will increase rapidly in a short period of time. This will be a milestone event for the company and will further expand the market influence of Yiwei Lithium Energy.
