Ziguang Group responded to the merger of Spreadtrum and RDA, stating that the integration aims to promote coordinated development within Ziguang Exhibition. The company officially commented on the news that Spreadtrum RDA had announced their merger, emphasizing that the combination will help realize a more unified strategy, product planning, marketing organization, and operational management across various areas.
After the integration, Spreadtrum will continue to focus on the independent research and development of 2G/3G/4G/5G mobile communication baseband chips, while RDA will concentrate on IoT core technologies to better meet customer needs and ensure long-term satisfaction. In 2017, Ziguang Zhanrui secured a top-three position in the global mobile phone baseband chip market and became one of the world’s top ten IC design companies.
Since 2016, Ziguang has been integrating Spreadtrum and RDA into a unified structure. On January 19, 2018, the group further merged the two companies at the management and organizational level to maximize resource sharing and business synergy. This move aims to enhance innovation capabilities, independent chip design, and intellectual property rights, driving the group’s rapid growth through the “1+1=2†approach. As a result, the overall competitiveness and the strength of mid-to-high-end technology products have improved, contributing to the development of China’s semiconductor industry.
In December 2013, Ziguang acquired Spreadtrum for $1.8 billion, and in July 2014, it completed the acquisition of RDA for $907 million. The integration of these two companies has been closely watched by the industry. In February 2016, Ziguang Zhanrui was established, with both companies operating under its umbrella but maintaining separate systems and structures.
Within Ziguang Group’s broader industrial layout, the chip business plays an increasingly vital role. The merger of Spreadtrum and RDA is expected to leverage the group’s strengths, enable resource integration, and foster talent development, supporting the strategic implementation of “from core to cloud†and accelerating the rise of China’s semiconductor industry.
According to data from 2016, Ziguang Zhanrui became China’s largest chip design company, shipping over 1 billion chips annually, including 650 million mobile phone chips.

AI Vision Company Eye Engine launched the eyemoreX42 imaging chip at the 2018 Geek Park Innovation Conference. The eyemoreX42 is a high-performance imaging chip based on ultra-large-scale computing, self-developed algorithms, and over 500 scene datasets. It addresses key challenges in AI vision, such as low-light, backlight, and reflection conditions, ensuring stable and high-quality image output for AI vision systems.
The chip simulates the human eye's response to light, intelligently processing contrast and producing rich, detailed images with sharp color contrast. This makes it essential for front-end perception systems in AI vision, acting as the "eye" of the AI cognitive world. Currently, eyemore focuses on four key markets: autonomous driving, smartphone AI imaging, high-end intelligent security, and industrial visual imaging.
The AI face recognition-driven security market is highly promising, and eyemore’s imaging engine helps visual AI companies obtain high-quality image data, improving recognition accuracy. For the autopilot market, eyemore plans to collaborate with providers to develop car-level imaging modules and chips. In the smartphone sector, more manufacturers are incorporating AI camera features, making eyemore’s technology a valuable support for them.

Pan Jianwei’s team achieved a milestone in intercontinental quantum communication. The world’s first quantum communication satellite, Mozi, successfully completed a secure quantum communication link between Beijing and Austria, covering a distance of 7,600 kilometers. Beijing sent a 5.34kB photo of "Mozi" to Vienna, while Vienna sent a 4.9kB Schrödinger photo back, using an 80kbit quantum key for one-time encryption.
This collaboration involved Professor Pan Jianwei and his doctoral advisor, Professor Anton Zeilinger of the Austrian Academy of Sciences. The quantum keys were generated at ground stations in Xinglong (near Beijing) and Graz (near Vienna), and the satellite performed a bitwise XOR operation on the keys before sending the result to one station, establishing a secure password channel.
Additionally, a quantum-secured video conference lasting 75 minutes was held between Chinese and Austrian scientists, transmitting about 2 GB of data using a 128-bit encryption standard. Both sides exchanged a 560-kbit quantum key.
Quantum key distribution offers unconditional security, unlike traditional public-key cryptography, which can theoretically be cracked. Any eavesdropping would disrupt the system due to the quantum non-cloning principle.
Over the past decade, Pan Jianwei’s team has extended quantum entanglement distribution from dozens of kilometers to 404 km, enabling inter-city quantum communication. However, fiber or ground-based transmission suffers from significant loss, limiting communication distance. Using satellites like Mozi, photons travel mostly through vacuum, minimizing loss and decoherence.
Launched in August 2016, Mozi operates in a 500km low-Earth orbit, with five ground stations in Hebei, Xinjiang, Qinghai, Yunnan, and Tibet. In 2017, Mozi completed three major scientific objectives: over 1,200 km of satellite-decoy quantum key distribution, 1,200 km of star-ground quantum entanglement distribution, and quantum teleportation.
These achievements laid the foundation for a global quantum communication network. The results showed that satellite links are over 20 orders of magnitude more efficient than fiber for quantum key distribution.
Today, the ground “Beijing-Shanghai trunk line†and the “Mozi†satellite link form a comprehensive quantum communication network. By the end of September 2017, the world’s first quantum-secured communication backbone, the “Beijing-Shanghai Main Line,†was officially opened, spanning 2,000 km and connecting multiple sites. Government agencies and financial institutions are now testing the quantum communication network through practical applications.
Low Voltage Lithium Battery
Low-voltage lithium batteries for energy storage
Low-voltage lithium batteries are becoming more and more popular for energy storage. These batteries have a number of advantages over traditional lead-acid batteries, including longer life, smaller size, and lower weight.
1. Introduction to low-voltage lithium batteries
Lithium ion batteries are a type of rechargeable Battery that use lithium ions to store energy. They have a high energy density, making them ideal for portable devices. Low-voltage lithium ion batteries are a type of lithium ion battery that have a reduced voltage. This makes them safer for use in devices that are not safety-rated for high voltages.
2. Applications of low-voltage lithium batteries for energy storage
Low-voltage lithium batteries are finding an increasing number of applications in the energy storage sector. Their high energy density and long cycle life make them well-suited for use in grid-scale storage systems, while their relatively low cost and easy installation make them attractive for use in small-scale applications such as home energy storage systems.
Low-voltage lithium batteries are also being explored as a potential storage solution for renewable energy sources such as solar and wind power. By storing energy from these sources when it is available and releasing it when needed, low-voltage lithium batteries can help to smooth out the peaks and valleys in renewable energy output, making these sources more reliable and efficient.
Low-voltage lithium batteries are the future of energy storage. They are smaller, lighter, and longer lasting than traditional lead-acid batteries, making them perfect for a wide range of applications.
