In November 2019, the representatives of Huawei Technologies Co., Ltd. came for a visit and exchanges. The R&D director of our team introduced the advantages and development progress of the new battery technology in detail. New battery products using high-capacity, low-cost new anode materials which will significantly increase energy density and reduce costs, and have the advantages of wide temperature range, environmental protection and easy recycling. The products have good market application prospects in electric bicycles, scooters, medical equipment, small household appliances power, backup power, home and photovoltaic energy storage, communication energy storage, new energy vehicles and other application scenarios. The two parties formally signed a project cooperation agreement on the low-cost and long-life large-scale energy storage battery technology project. We will jointly develop new products of long-life and low-cost energy storage battery, which will be put into the application market of energy storage battery such as backup power supply, home and photovoltaic energy storage, communication base station, etc.
