SMM: September 10, 2019, Dongxu Optoelectronic Technology Co., Ltd. holding subsidiary Shanghai carbon Source Huigu New material Technology Co., Ltd. held a new product launch in Shanghai. The meeting released the company's latest successful development and commercial application of graphene-based forklift lithium-ion battery three series of 9 products, and with Shenzhen Hongtianyang Technology Development Co., Ltd., Yi Innovation Energy (Shanghai) Co., Ltd. signed the "graphene-based forklift lithium ion battery product sales and cooperation agreement" (hereinafter referred to as "sales cooperation agreement").
The three series and 9 products of graphene-based forklift lithium-ion battery developed by carbon source and sink valley belong to graphene-based lithium-ion large power battery technology. it is an important leap in the application of graphene-based lithium-ion battery technology from fast charging technology, small power tool battery to industrial large power battery application. The "sales Cooperation Agreement" signed at the new product launch involves a total pre-sale of not less than 3000 sets (sets).
In recent years, the global and Chinese forklift market is growing rapidly, especially the electric forklift market in China. As it is the general trend for lithium-ion battery to replace lead-acid battery, and the intelligent iterative upgrading of forklift technology, lithium-ion battery forklift has gradually become the mainstream, and the market demand of forklift lithium-ion battery is expanding rapidly. The excellent performance of graphene lithium ion battery technology meets the needs of mainstream electric forklift trucks. The main materials of forklift lithium ion battery include positive and negative electrode material, electrolyte, diaphragm and so on. Cathode material is one of the core materials of lithium ion battery, and its performance directly affects the performance of lithium ion battery. Since 2014, carbon Source Huigu has focused on the preparation technology of high-quality graphene materials and the development of graphene coated cathode materials. The super fast charging technology of the second generation graphene mobile power supply was successfully launched in 2016 and 2017, and has been successfully applied in small power tools and electric bicycles. The core of the first series of graphene forklift lithium ion battery series released in China is the successful development of graphene based fast charge rate cell on the basis of unique monolayer graphene coating technology. The product has the advantages of fast charging speed and long cycle life, and is equipped with specially developed intelligent battery management system, dynamic variable power output system, and the first battery damping suspension system. The use of leading thermal management technology and innovative armored plug-in counterweight design.
According to the information disclosed by Dongxu Optoelectronics, the cycle life of the product reaches an average of 5000 times under the condition of 5C charge and discharge, which can meet the normal operation between-20 ℃ and + 60 ℃, and the charge and discharge efficiency is ≥ 98%. Different from conventional power lithium-ion batteries, this product is a graphene-based lithium-ion battery for the electric forklift market.
Wang Lipeng, chairman of Dongxu Optoelectronics, said the release of lithium-ion batteries for graphene-based forklifts was the starting point for the second take-off of Dongxu's optoelectronic graphene business. "Dongxu Optoelectronics will graphene as an important development strategy of the company has not changed, and continues to add strength."
