On December 1st, Huawei’s official website published a report titled “Huawei’s Major Breakthrough in the Study of Graphene-Assisted High-Temperature Lithium-Ion Batteries â€. According to reports, Huawei has achieved significant research breakthroughs in the field of lithium-ion batteries, introducing the industry's first high-temperature long-life graphene-assisted lithium-ion battery.
Subsequently, a news began to spread, the news that Shanshan shares mastered Huawei's graphene battery patent, will benefit from the commercialization of graphene battery technology. Affected by this news, the stock price of Shanshan shares has changed in recent days, and the trading volume has been significantly enlarged. However, after verifying the news, the author found that Shanshan and Huawei had no cooperation in the field of graphene.

On December 1st, Huawei official website news showed that Huawei Watt Labs recently announced a major research breakthrough in the field of lithium-ion batteries at the 57th Japan Battery Conference, introducing the industry's first high-temperature long-life graphene-assisted lithium-ion battery. The experimental results show that the new high temperature resistant technology based on graphene can increase the upper limit of lithium ion battery use temperature by 10 °C, and the service life is twice that of ordinary lithium ion batteries.
Dr. Li Yangxing, chief scientist of Huawei Watt Lab, pointed out that the technical breakthrough of graphene-assisted high-temperature lithium-ion battery mainly comes from three aspects: adding special additives to the electrolyte to remove trace water and avoiding pyrolysis of the electrolyte; The modified large single crystal ternary material improves the thermal stability of the material; at the same time, the new material graphene can realize efficient heat dissipation between the lithium ion battery and the environment.
It is understood that this research will bring innovation to the energy storage business of communication base stations. The external base station using the high-temperature lithium-ion battery in hot areas can have a working life of more than 4 years. Graphene-assisted lithium-ion batteries will also help electric vehicles last for a long time in high-temperature environments, as well as safe flight under high-temperature heating of drones.
On December 5th, a message "Huawei Graphene Battery Deep Excavation: The Patent Owner of Shanshan Shares" was circulated on the Internet. Related content shows that Dr. Li Yangxing was the chief scientist of Huawei Watt Lab in June 2016. He was previously the CTO (CTO) of Hunan Shanshan Energy Technology Co., Ltd., a wholly-owned subsidiary of Shanshan. The news also said that "this Huawei research results were jointly completed by Huawei and Shanshan under the influence of Dr. Li Yangxing", "Huawei successfully commercialized graphene battery technology, and the related patent owner Shanshan will become The only directly benefiting A-share listed company."
Affected by this news, the stock price of Shanshan shares changed on December 5 and 6. Among them, on December 5, the stock price of Shanshan shares rose 6.82% against the trend, with a turnover of 388 million yuan; on December 6, it continued to rise 0.19%, with a turnover of 805 million yuan.
â— The two sides have no cooperation in the field of graphene
It is noteworthy that graphene, as a new type of material, has been receiving much attention from the market, and some of them have seen stock prices rise due to the stimulation of graphene.
Therefore, whether there is a cooperative relationship between Shanshan and Huawei, is the patent for Huawei's graphene-assisted lithium battery really in the hands of Shanshan? These are all affecting the sensitive nerves of investors.
On the afternoon of December 6, the reporter called Shanshan as an investor. The staff of the company's securities department said that the company had no cooperation with Huawei in the field of graphene battery technology. Before, there was a cooperation project with Huawei in the fast charging of lithium batteries, but It has nothing to do with graphene materials.
Interestingly, the staff also said that the company also noticed the news that "Huawei graphene battery deep excavation: the patent owner used is Shanshan." The company is verifying this news, but it should not involve graphene batteries. The news may be partially wrong, not a fact.
In addition, the reporter also learned that although the above news may have caused "Oolong", but for graphene materials, Shanshan has been doing follow-up research.
For the current development of graphene materials, the above staff said that graphene has no industrial feasibility at this stage, mainly in the research and development stage.
