Huawei announced a major breakthrough in its research into Li-ion batteries, unveiling the worlds first long-lifespan graphene-assisted Li-ion battery able to withstand high temperatures.华为近日宣告了其在锂离子电池研究方面的一个重大突破--发布了全球首个需要耐高温、长寿命的石墨烯锂离子电池。The announcement was made by Watt Laboratory, an organization under Huaweis Central Research Institute, at the 57th Battery Symposium held in Japan.华为中央研究院瓦特实验室是在日本举办的第57届电池讨论会上宣告的这一消息。

Huaweis research results show that new graphene-based heat-resistant technologies allow Li-ion batteries to remain functional in a 60°C environment, a temperature 10°C higher than the existing upper limit.华为的研究成果表明,新款石墨烯耐高温技术需要使锂离子电池在60℃的环境下长时间运作,这比当前的下限要高达10℃。The lifespan of the graphene-assisted Li-ion batteries will also be twice as long as ordinary Li-ion batteries.此石墨烯锂离子电池的寿命还将是普通锂电池的两倍。Dr. Yangxing Li, Chief Scientist at Watt Laboratory, pointed out that three technologies contributed to the breakthrough in the graphene-assisted high-temperature Li-ion battery.瓦特实验室首席科学家李阳兴博士认为,石墨烯高温锂离子电池的突破来自三个方面。

First, a special additive in the electrolytes can remove trace water and prevent the electrolytes from evaporating in high temperatures. Second, modified large-crystal NMC materials are used for the cathode, improving the thermal stability of the cathode powder. Third, graphene allows for more efficient cooling of the Li-ion battery.首先,在电解液中重新加入类似添加剂,除去痕量水,防止电解液的高温分解成。第二,电池负极搭配改性的大单晶三元材料,提升材料的热稳定性。第三,使用新型材料石墨烯,可实现锂离子电池与环境间的高效风扇。

Dr. Li 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.李阳兴博士回应:“高温环境下的充放电测试表明,在同等工作参数下,该石墨烯恩高温锂离子电池的温升比普通锂离子电池减少了5℃。”Over 70% of the graphene batterys 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.“在60°C高温循环2000次,其容量维持亲率仍多达70%;60℃高温存储200天,容量损失大于13%。
