Amionx, the California company has won headlines for its explosion-free battery technology; the company expects to license its advance for use in commercial products by the end of 2019. OK, for the record, as we surround ourselves with more lithium-ion-powered devices, lithium-ion batteries are safe and incident-free. The big "but" is that explodingbatteries or batteries catching fire do happen and it would be wonderful if we could figure out how to lower the risk. CNET wrote, "on the rare occasions lithium batteries go wrong, they can go catastrophically wrong."The company with answers is Amionx and its solution is SafeCore.Amy Nordrum wrote about it in IEEE Spectrum: "Amionx says its patented battery technology, called SafeCore, makes it less likely that a battery will explode or catch fire due to thermal runaway."Its time has come. "The continued miniaturization of electronics has given rise to more compact and efficient battery technologies. Unfortunately, it has increased the number of incidents of catastrophic battery failure as well," said Cal Jeffrey in TechSpot.The Amionx team has been working on the challenge: What if lithium-ion batteries could be made to be so reliable that even a catastrophic structural failure—up to and including being pierced by a bullet—wouldn't cause them to explode?Earlier this year, CNET put SafeCore batteries and normal lithium-ion competitors to a range of "torture" tests. The results in brief: "When we stabbed, shot and smashed the "brand X" batteries, they burst into beautiful, brilliant, scary flame. But under identical conditions, the SafeCore batteries didn't catch fire," said Hollister.He described their factory floor with a lithium-ion battery assembly line. The company is a spinout of American Lithium Energy, founded in 2006 by Dr. Jiang Fan and Dr. Robert Spotnitz.How SafeCore works: This is a layer inside the power cell and if something goes wrong it kicks in and the battery stays safe."SafeCore doesn't change the components of the battery itself," said Angela Chen, in The Verge, back in August. "It's an extra layer of material inside the cell that stops the fire before it begins. When triggered by something like too much heat or too-high voltage, the layer breaks the connection between the electrodes and the part of the battery responsible for regulating how the electricity moves through the device. That shuts down the battery entirely."Sean Hollister in CNET said that "the company's scientists discovered a formula they claim could easily be applied to existing battery manufacturing lines—no new machines required."Amionx CEO Jenna King was quoted in CNET: "I think this technology makes sense to ultimately appear in every lithium battery in the world."Several reports said Amionx was in talks with some manufacturers to license the SafeCore tech.How much of an impact will this company's technology actually have down the road? IEEE Spectrum shared some views outside the company: "Paul Kohl, a chemical engineer at Georgia Tech, and Huazhen Fang, a mechanical engineer at the University of Kansas, both say that Amionx is taking a unique approach to battery safety that they haven't seen before." Fang said compared to some other R&D efforts, this technology was "more pragmatic." Source: https://techxplore.com/news/2018-12-lithium-ion-batteries-behavior.html

Demand for lithium, one of the key materials used in making lithium ion batteries, is rising rapidly. The metal is used in a wide variety of industrial applications including glass, ceramics and greases, but it’s the use of lithium as a key component in the batteries that power electric and hybrid electric vehicles that has so excited markets.Lithium does not occur naturally in nature. Instead it is found in a variety of mineral salts which needs to be chemically processed to form the lithium compounds and chemicals required by industry. A number of lithium compounds are used by industry but it is lithium carbonate that is the most commonly used form of lithium, accounting for more than half of total demand. The lithium industry often expresses lithium production and trade in lithium carbonate equivalent (LCE) units.If electric vehicles, which rely wholly or partly on electricity stored in batteries as their source of energy, revolutionize road transport in the way many expect, demand for the metal will rise exponentially. China will be at the forefront of this.China is already the world’s largest market for EVs, accounting for nearly half of global sales last year. This trend is expected to continue, supported by government policies driving the development and adoption of electric vehicles. This will require a significant increase in both lithium carbonate and increasingly lithium hydroxide, another lithium compound, which is the preferred basis for the next generation of lithium battery technologies.China accounted for slightly more than half of total global production last year producing 123,000 tons LCE, according to statistics from the China Nonferrous Metals Industry Association (CNMIA). Of this, 83,000 tons was lithium carbonate with the remainder comprising other compounds like lithium hydroxide, lithium chloride and lithium metal.China is very reliant on imported raw materials with many Chinese producers using concentrated spodumene, a mineral form of the metal mainly imported from Australia, to produce products including lithium carbonate. This is expensive and the cost of producing a ton of lithium carbonate at some Chinese producers using imported spodumene is reported to be more than $10,000 a ton. In contrast, producers like those in Chile that produce lithium carbonate from mineral brines may have costs under $2,500 a ton.Strong lithium demand over the last few years has seen high-cost Chinese producers using imported spodumene set the marginal price. This has been reflected in the average price of imported lithium carbonate, which has more than doubled over the past year and a half, according to customs data. The price of battery-grade material is even higher, with S&P Global Platts assessing battery-grade lithium carbonate CIF North Asia at $17,250/mt in early June.With demand continuing to outstrip supply and prices holding at elevated levels, imports remained strong in the first quarter of this year, rising 13% on the same period in 2017.In a bid to secure future supplies Chinese companies have therefore been looking overseas. China’s Tianqi Lithium controls 51% of Talison Lithium, the world’s largest spodumene producer, most of which is shipped to China. And in May Tianqi Lithium also bought 24% of Chile’s SQM, the world’s lowest-cost lithium producer. This should support continuing imports of lithium carbonate into China even whilst a number of new Australian spodumene projects come online.One unique feature of the Chinese electric vehicle market is the popularity of battery (BEV) and plug-in hybrid (PHEV) electric buses. Due to city governments favoring cleaner battery technologies over diesel engines, EV buses last year accounted for over 20% of total sales of buses in China. This contrasts markedly with passenger BEV and PHEV volumes, which although much higher in absolute terms, accounted for under 2.5% of total car sales.A new policy introduced this year to promote development and production of EVs is expected to change the landscape for EVs in China. Though ambitious, it could see annual EV sales reach 7 million units by 2025, accounting for 20% of new passenger car sales.LITHIUM WILL BE A KEY COMPONENT OF BATTERIES FOR MANY YEARSThis increase in battery production will see a significant rise in demand for metals like cobalt, nickel and lithium. Lithium carbonate is currently the predominant form of the metal used by battery makers in China, where it is used in the LFP (lithium-iron-phosphate) batteries that are commonly used by Chinese vehicle manufacturers including BYD, FAW-Volkswagen, Geely and Great Wall Motors.Newer battery technologies like NCA (nickel-cobalt-aluminum) and NMC (nickel-manganese-cobalt) produce more energy for their size than LFP technology, but are more expensive owing to the use of nickel and cobalt. Regardless of the battery technology and the amount and proportions of other metals, the lithium intensity of batteries — the amount of lithium used per unit of energy the battery produces — remains more or less the same. While lithium intensity is expected to decline slightly over the next decade, this will be offset by a shift to larger battery packs to give EVs the range that consumers demand.The next generation of NCA and NMC 811 batteries, which use eight parts nickel to one part each of manganese and cobalt, will favor the use of lithium hydroxide. However, it is likely that LFP batteries will continue to be used in China. LFP batteries do not provide as much energy as an NCA or NMC battery of the same weight, but in addition to being cheaper to produce they have a higher thermal stability, making them safer. NCA batteries in particular can be unstable and prone to overheating, causing fires. LFP batteries are therefore likely to continue to be used in China, especially in vehicles like electric buses where safety is of paramount importance.The battery packs used in BEV and PHEV buses are on average much larger than those found in passenger cars, which means that they have been a significant driver of lithium demand. Indeed, S&P Global Platts estimates that in 2017 buses accounted for around 45% of all lithium demand from the Chinese EV sector.Given the government’s desire to reduce air pollution and develop China as a leader in EV technology, we think that commercial vehicles, and buses in particular, will continue to be significant driver of EV penetration in China in the years ahead. Source: https://blogs.platts.com/2018/06/22/lithium-electric-vehicle-battery-technology/
