Dongguan Liwei Energy Technology Co., Ltd. mainly produces and consumes 3C batteries, which are widely used in mobile phones, notebook computers, intelligent hardware and other consumer 3C products. In addition to the original production base in Dongguan, Liwei has now completed expansion in Huizhou Park. In 2017, Dongguan Liwei has entered the supply chain of some domestic high-end brand customers. The market reputation and customer recognition are good, and production and sales continue to grow. In the second half of 2018, Dongguan Liwei will gradually enter the supply chain of domestic mainstream high-end mobile phone brand manufacturers, and the market share will be further improved. As the self-sufficiency ratio of the company's consumption of 3C batteries continues to increase, the company's overall revenue and profit margin will be further improved.
