Ranking the top ten lithium batteries

Evening news of August 31, Beijing time, "MIT Technology Review" A published article recently indicated that to date we have not used energy storage devices that are better than 40 year old lithium-ion batteries. Indeed, the development of new batteries not only faces numerous technical challenges, but also requires significant financial investments. support.
Earlier this year, EllenWilliams, director of the U.S. Department of Energy's Alternative Energy Advanced Research Program (hereinafter referred to as "ARPA-E"), made headlines in major media outlets overnight. The reason is that she said in an interview with the British "Guardian": "We have made a major breakthrough in the field of batteries."
Although more than 75 storage research projects energy projects supported by ARPA- Some satisfactory results have been achieved, but no decisive progress has been made in the production of small, low-cost energy storage devices.
Many startups are close to producing an affordable, safe, compact energy storage device with high energy density, costing less than $100 per kilowatt hour. However, if the price of energy storage equipment remains below $100 per kilowatt hour, galvanic effects will inevitably occur.viably.
The galvanic corrosion effect refers to local corrosion at the contact point of different metals in the same medium due to the difference in corrosion potential. To overcome this problem, renewable energy must be harnessed. Although renewable energy sources like solar and wind can make electric vehicles lighter and cheaper, these energy sources are only possible when the sun is shining or the wind is blowing.
However, the speed of commercialization of this new type of battery is much slower than the current shift from fossil fuels to renewable energy. Even Tesla CEO Elon Musk, who is confident in these new energy technologies, has to admit that current automakers haven't made much progress in improving lithium batteries.
In fact, many researchers believe thatSubstantial advances in energy storage will require a completely new chemical process and physical form. Only in this way can we surpass the achievements of lithium-ion batteries over the past decade in the fields of consumer electronics, electric vehicles and grid storage systems.
In May of this year, the US Department of Energy held a seminar titled “Beyond Lithium-ion Batteries”. In fact, this is already the ninth edition and aims to discuss the technical challenges encountered in the development of new energy storage devices.
Qichao Hu, founder of SolidEnergy Systems, an MIT spin-off company, has developed a new type of lithium metal battery. This new type of battery significantly increases the energy density of battery devices, far exceeding that of current batteries.
He declared: “DuringIn more than ten years of research and development of new battery systems, the main obstacle encountered is: how to transform an idea into a product. This is even more important for batteries. This is even more difficult, because if you improve the performance of one aspect, it may affect the performance of another aspect. Therefore, there must be compromises. "
In addition, energy storage research also faces a multiplicity. (multiplicity) question: There are many battery technologies, from foam batteries to flow batteries to chemical batteries. Among these battery technologies, there is no clear winner yet. This leads to research fragmentation and uncertainty.
Data from Lux Research. research, show that over the past eight years, startups researching the next generation of new batteries have not rreceived an average of $40 million in financial support. For comparison, Tesla will invest around $5 billion in its Giga factory which produces lithium-ion batteries. Closing a huge investment gap is difficult.
Gerd Ceder, professor of materials science at the University of California, Berkeley, said: "It will cost about $500 million to build a complete small production line. Automakers are taking purchasing decisions Before, it could take several years to test a new battery system. So if your company can only get $5 million in funding per year, it's almost impossible for you to invest $500 million. in building a factory to produce new batteries "
Even if new battery manufacturers succeed in bringing this new technology to market, they will have difficulty scaling up.their production and to find buyers. This was previously the case for Leyden Energy and A123 Systems. Even though they had new technologies, they still failed due to lack of funds and demand that did not meet expectations. There are also two startups, Seeo and Sakti3, which were acquired cheaply before mass production.
At the same time, Samsung, LG and Panasonic, the world's three largest battery manufacturers, have also adjusted their strategies and are increasingly less interested in investing in new technology batteries, preferring to improve their current products. Additionally, these new battery startups face a problem they don't want to talk about: lithium-ion batteries developed in the 1970s have been continually improved.
