Recently, rival Nikola Corp. said it plans to launch a "disruptive ” technology, which will be shown in 2020. Nicholas said the technology could double the range of electric vehicles to 600 miles without changing the battery size or adding weight. Nikola's semitrailer can last up to 800 miles on a single charge. The new batteries developed contain lithium, but give up most of the cobalt, magnesium, nickel and aluminum. The positive and negative energy density of the battery is four times that of the current lithium battery. According to reports, these batteries have been charged 2000 times in the laboratory, with a feasible life, but they have not been measured on the road. Nikolai also plans to share intellectual property rights in the technology with other automakers. Nikolai has been working on the development of battery trucks. In February this year, Nikolai suddenly announced the option of adding pure electricity to its product line, which will provide two / tre models with pure electricity version similar to Tesla semi electric trucks, thus officially entering the short distance electric freight market. Among them, the pure electric tre will use about 69000 lithium batteries, with a single endurance of 400 miles (644 kilometers). But some in the industry are skeptical. Sam Jaffe, executive director of Cairn era, a U.S. energy storage research and consulting firm, said he was skeptical of the company's statement because of Nicholas's refusal to produce performance data or disclose the university laboratory with which it worked. Over exaggeration of breakthrough battery technology has been the norm in the industry over the past few decades, Jaffe said. This has happened many times before, which is not good for the whole industry. Because when people see these exaggerated statements, they will think that the charging problem has been solved, but it is not the case. It's still hard to make a breakthrough in battery technology. In fact, there is rarely a new chemical that has never been used before that can replace the existing one and change the world. Trevor Milton, chief executive of Nikola, said Nikola was never afraid of questions from the outside world and had been criticized as a myth when it announced the launch of the truck, but that was not the case. In fact, in recent months, Nikola and Tesla respectively announced significant breakthroughs in power battery technology. However, while the industry cheered for this, the voice of doubt has not been cut off. In April this year, Tesla CEO Elon - has revealed that the newly developed lithium battery can provide more than 1 million miles (about 1.6 million kilometers) of battery life for Tesla electric vehicles. Compared with the model 3 battery module, which can only withstand 1500 charging cycles, the new battery can withstand 4000 charging cycles with a total range of 300000-500000 miles (about 480000-800000 km). In September, researchers at the University of Dalhousie in Canada published a related paper, while musk filed a patent application for a million mile battery technology. According to the research, the new battery life will be two to three times that of the existing Tesla battery, and will be applied to robot taxis, long-distance electric trucks and power grids.
