December 1, Huawei's Central Research Institute of Wart Laboratories at the 57th session of the Japanese battery conference announced in the field of lithium-ion battery to achieve a major breakthrough in research, introduced the industry's first high-temperature long-life graphene lithium-ion battery. Experimental results show that the new high-temperature technology based on graphene can increase the use of lithium-ion battery temperature 10 ℃, the life of ordinary lithium-ion battery is 2 times.
Dr. Li Yangxing, chief scientist of Huawei Watt Laboratory, pointed out that the breakthrough of graphene-based high-temperature lithium-ion battery technology mainly comes from three aspects: adding special additives in the electrolyte, removing trace water and avoiding the pyrolysis of the electrolyte; Of the large single crystal ternary material to improve the thermal stability of the material; the same time, the use of new materials graphene, lithium ion battery can be achieved between the efficient heat dissipation.
The charge-discharge test in the high-temperature environment shows that the temperature of the graphene-based high-temperature lithium-ion battery is 5 ℃ lower than that of the ordinary lithium-ion battery under the same working parameters. The capacity retention rate is still over 70% at 60 ° C, ; 60 ℃ high temperature storage 200 days, capacity loss less than 13%, "Dr. Li Yangxing said.
The results of this research will bring innovation to the storage base station's energy storage business. In the hot areas using the high-temperature lithium-ion battery plug-in base station working life of up to 4 years. Graphene lithium-ion battery will also help electric vehicles in high temperature environment lasting life, and UAV high temperature heating under the safe flight.
Last year, Huawei Wart Laboratories in the 56th session of the Japan Battery Assembly (The 56th Battery Symposium in Japan) on the release of 5 minutes to full of 3000mAh battery 48% of the fast charge technology results, causing widespread concern in the industry. According to Dr. Li Yangxing said, Huawei fast battery has been commercial, and will be officially released at the end of December this year, super fast charge mobile phone.
High temperature long life graphene lithium-ion battery technology if applied to the phone, Moreover, regardless of whether the fast charge technology is equipped, but the endurance and heat and drought resistance, is enough to go beyond Apple.
High temperature long life graphene lithium-ion battery technology Previously there have been some technology companies have been able to be developed to be put into use, but later but no audio, if the Huawei technology can be put into use as soon as possible for the battery, mobile phone, technology Industry may mean a new change.
