November 24, a three-day global battery industry event - the Fifth China Lithium New Energy Industry International Forum (ABEC 2017, lithium "Davos") upsurge, the global lithium new energy industry chain more than 700 Top domestic and foreign first-class business guests, well-known institutions and industry leaders gathered at a high level, in-depth exchange industry hot topics to discuss the future direction of lithium battery industry.
At the meeting, Secretary OptimumNano, chairman of the board issued a "new challenge to find a new path," a brilliant speech, for nowadays battery industry, "a mixed bag" of the new environment, put forward "full cost reduction" and " Energy density "two major new path of development, aroused enthusiastic response at the scene.
"Undoubtedly, the good momentum of the development of new energy vehicles in China is continuing in 2017. As of this year, China has ranked No.1 in the world for sales and production for eight consecutive years, which is a great news for power battery enterprises," said Zhong Meng-guang.
After China's "13th Five-Year Plan" requires a substantial increase in the application of new energy vehicles and the promotion of green low-carbon industries such as new energy vehicles as the pillar industries in China, the new energy automotive industry has been rapidly developed. Since 2009, China's production and sales of new energy vehicles have ranked first in the world for 8 consecutive years, and some segments have been able to compete with international brands on the same stage. It can be said that the development of new energy automotive industry this fire, burning very prosperous.
However, the market last week reported that the national recovery slope policy, energy density requirements increase, in the excited period of power battery companies like ice water. Although favorable industrial policies and booming production and sales, the challenges are twofold: on the one hand, the price of materials continues to rise, causing the cost of manufacturing to not be synchronized with the rate of national recovery from deforestation; on the other hand, 30,000 km The impact of the recession, the impact of vehicle OEM payment, power battery enterprises can be described as squeezed by both ends.
OptimumNano delivered a keynote speech titled "Responding to New Challenges and Finding a New Path"
Centralization of the battery industry, vertical alliance alliance, industry survival of the fittest, the first echelon bigger and stronger trend has been irreversible. As the state subsidies for new energy vehicles once again reduce the amount of control over manufacturing costs put forward by the test. At the same time, the policy adjustment will support the request of the energy density of the power battery to be further promoted, which poses a challenge to the battery technology research and development. In the face of a new round of industry reshuffle, Zhong Menguang suggested that power battery companies make their own efforts in reducing costs and increasing energy density.
Among them, there are three ways to reduce costs: First, improve the process, reduce material costs; the second is to use smart manufacturing to expand the scale effect and improve the yield, reduce production costs; third is decommissioning batteries and scrapped batteries for echelon, reduce life-cycle costs .
"To expand the scale effect and improve the yield and reduce the production cost, it is very important to push the production of automatic production, promote intelligent manufacturing .Wotma from 2016 to promote automated production and intelligent manufacturing, the current results, 1GWH PACK artificial production costs from 33 million down to the current 2.5 million, cost savings of 30.5 million. "Zhong Meng Guang revealed. By promoting intelligent manufacturing, not only the manufacturing cost is saved, but also the production efficiency of OptimumNano is significantly increased, the product defects are reduced, and the product qualification rate is improved. At present, Watma product defect rate control within 900ppm, which is a very important indicator of product quality.
There are two ways to improve the energy density of the battery: First, the use of large-capacity batteries, through the capacitor to enhance the voltage upgrade and lightweight design to achieve from 145Wh / Kg to 160Wh / Kg upgrade; the second is from the system planning and detailed design level Improve PACK efficiency.
Achieving the dynamic battery high energy density, high safety, high power performance, long cycle life dynamic balance of the four major performance is the ultimate goal of the battery companies. How to ensure these four properties, the strategy adopted by OptimumNano is the Walter SMART strategy and accelerates the smart manufacturing, quality improvement achieved remarkable results, which will help Walter move from the traditional power battery manufacturers to power Assembly system solutions provider changes.
Finally, Zhong Mengguang said that as long as the power battery enterprises to strengthen technological research and innovation, promote intelligent manufacturing, and strengthen the recycling of R & D and application, in the new environment and new challenges, the country will certainly be able to find a new path to break through the dilemma.
