On December 12, Sunwoda announced that its subsidiary, Sunwoda EVB, had signed a "Strategic Cooperation Framework Agreement on Solid-State Batteries" with Xiamen Tungsten New Energy Materials Co., Ltd. (referred to as "XTC New Energy"). Based on the complementarity and compatibility of both parties in strategic cooperation, they will jointly develop a series of new energy battery materials for solid-state batteries and expand their business collaboration at an appropriate time.
According to the announcement, the cooperation covers four main areas: the development of cathode materials for solid-state batteries, the development of electrolytes and related materials for solid-state batteries, the joint development of solid-state batteries, and industrialization cooperation.
Sunwoda stated that the agreement will help both parties establish a long-term, stable strategic partnership, leverage their respective market and technological advantages, and create synergistic business effects. This collaboration will positively impact the development of high-energy-density, high-safety solid-state batteries using new cathode materials and solid electrolytes, aligning with the company's development strategy. It will also enhance the company's R&D capabilities and overall competitiveness, advancing the new energy industry chain.
Earlier, on July 5, Sunwoda EVB signed the "Framework Agreement on Joint Construction of the Dongguan Songshan Lake Solid-State Battery Public R&D Platform" with the Songshan Lake Materials Laboratory. Both parties agreed to jointly build the Songshan Lake Solid-State Battery Public R&D Platform, which will attract top domestic and international talent and teams in solid-state battery research, forming a strong collaborative R&D effort. The platform will also be equipped with advanced research facilities and laboratories to provide robust support for solid-state battery technology development.
Sunwoda EVB has been involved in the solid-state battery sector for many years. The first generation of semi-solid-state batteries has been developed, achieving an energy density of over 300Wh/kg with over 1,100 cycles. These batteries can pass penetration tests and 170°C thermal box tests. Consumer-grade semi-solid-state batteries have already entered mass production, with the capacity to scale up based on market and customer demand. The company's solid-state power batteries are currently in the laboratory phase and are actively engaging with clients in related fields. By utilizing lithium metal anodes, the energy density of solid-state batteries has been further increased to 500Wh/kg, with laboratory prototype samples available. It is expected that by 2027, the company will complete the development of laboratory samples of fully solid-state batteries with an energy density exceeding 700Wh/kg.
