Huawei’s R&D investment powers a major breakthrough for warm climates Huawei, the 8th largest in terms of R&D unveiled the first long-lifespan Graphene -assisted Li-ion battery

Beirut, February 15th, 2017: Huawei was ranked as the world’s eighth-largest company in terms of research and development spending in 2016, according to EU Industrial R&D Investment Scoreboard, an annual ranking of the world’s top 2,500 R&D investors. The global technology manufacturer’s significant investment in research and development has led to major breakthroughs in the industry including the first long-lifespan graphene-assisted Li-ion battery able to withstand high temperatures.

According to the rankings compiled by European Commission’s Economics of Industrial Research and Innovation, R&D spending by Chinese companies increased 24.7% from previous year, boosting its share of the global total from 5.9% to 7.2%. Furthermore, the scoreboard shows that the largest groups of companies in the world top 2,500 companies are drawn from the ICT, health care and automotive industries.

Huawei’s investment into the Huawei Central Research Institute has led to developments in a number of technological advancements including their latest breakthrough – Li-ion batteries. The Watt Laboratory, an organization under Huawei’s Central Research Institute Huawei announced at the 57th Battery Symposium held in Japan that Huawei plans to unveil Li-ion batteries featuring new graphene-assisted heat-resistant technologies. These technologies allow Li-ion batteries to remain functional in a 60°C environment, a temperature 10°C higher than the existing upper limit. The lifespan of the graphene-assisted Li-ion batteries will also be twice as long as ordinary Li-ion batteries, allowing for an unprecedented long battery life.

Dr. Yangxing Li, Chief Scientist at Watt Laboratory said, “We have performed charging and discharging tests in a high-temperature environment. The tests show that when working parameters are the same, the graphene-assisted high-temperature Li-ion battery is 5°C cooler than ordinary Li-ion batteries. Over 70% of the graphene-assisted battery’s capacity is left after it is recharged 2,000 times at a temperature of 60°C. Less than 13% of its capacity is lost after being kept in a 60°C environment for 200 days.”

Huawei’s research results will reshape the storage systems of communications base stations. In high-temperature regions and countries, outdoor base stations powered by the graphene-assisted high-temperature Li-ion batteries can have working lifespans longer than four years. These batteries ensure a high mileage for electric vehicles per charge in high temperatures. They can also guarantee the safe operation of drones, which often generate a significant amount of heat.

Huawei’s Watt Laboratory also revealed its quick charging technology, which recharges 48% of a 3000mAh battery in just 5 minutes. This technology turned many heads. According to Dr. Li, Huawei has commercialized the developed quick charging batteries and will announce a super-quick charging mobile phone in late December.
