          上個月,我很幸運在倫敦的電池技術展上進行了一次適度的會議。這是該會議的總結,以及我們自己的研究得出的一些其他見解。

           

          來自電池工業供應鏈的代表參加了有關可能在未來幾年內擾亂市場的技術和商業模式創新的討論。演講嘉賓包括主題專家,例如帝國拼貼學院戴森工程學院的高級講師比利·吳(Billy Wu)和儲能專利搜索與監控公司b-science的聯合創始人兼首席執行官Pirmin Ulmannm。

           

          遠離事件,我感到業界共識是,由于更新電池的出現,液體電解質電池的市場份額將迅速下降。觀點的差異在于商業上市的時機。

           

          1991年投入商業運營以來,液態鋰離子的性能一直在不斷提高。僅在最近幾年中,在大量研發資金的推動下,重大的技術進步才達到了替代電池化學的臨界點。在過去的24個月中,風險投資引起了人們的注意,并增加了對固態,超級電容器和氧化還原液流電池的投資活動,并推動了對鋅,硫和鉛等化學產品的投資回升(如圖1所示)。

           

          小組成員還提供了對其中某些技術當今地位的見解。

          固態電池

          顧名思義,固態電池利用固態材料來實現鋰離子在電池中的傳輸。 由于缺少合適的電解質候選材料,固態電池先前未能達到預期。 最近在實驗室級別獲得的增量收益導致各種成功的試點項目。 專家們解釋說,雖然如今帶有液體電解質的鋰離子電池已成為標準,但固體電解質卻是非揮發性的,這使固態電池本來就更安全。 它們還具有更高的能量密度。

          20182月,包括雷諾,日產,三菱和戴森在內的汽車OEM共同向固態電池初創公司Ionic Materials投資了6500萬美元。 Solid Power還籌集了2000萬美元用于2019年生產設施的準備,并準備與一系列戰略合作伙伴保持可持續增長。 QuantumScape6月份從大眾汽車公司獲得了1億美元的投資,盡管該公司沒有商品化的證據,但該公司使該公司處于早期的“獨角獸”地位。

           

          專家小組總結說,固態電池可能被大肆宣傳,他們將關注表現不佳的技術進步,即使在大規模部署之后,也會為固態電池的替代方法創造機會。戴森(Dyson)幾年前以9000萬美元收購固態電池開發商Sakti3就是一個最近的例子。該技術原計劃在其電動汽車中使用,計劃于2020年發布。但是,自收購以來,由于持續的商業化挑戰,該公司經歷了一系列挫折,導致戴森將子公司的價值減記了5,800萬美元。

           

          長期存儲的當前趨勢

          超級電容器,也稱為超級電容器,是討論的有前途的技術之一。與鋰離子電池相比,它們具有更高的循環穩定性(數百萬個循環),但能量密度較低。討論集中在超級電容器和固態電池的可能集成上。在組合式固態電池/超級電容器系統中,超級電容器可以彌補固態電池壽命和峰值功率性能方面的弱點。

           

          石墨烯衍生物和碳納米管可以改善超級電容器的性能,并在生產規模中得到越來越多的使用。早期市場參與者Skeleton Technologies是石墨烯超級電容器的制造商,致力于提高產量,將石墨烯超級電容器從高端領域推向大眾市場,同時通過交鑰匙儲能解決方案在價值鏈中向更高的方向發展。

           

          鋰離子電池中的硫

          關鍵行業參與者最近將鋰硫討論為一種有前途的電池技術,并開展了大量的研發活動。由于其高的能量密度和可利用性,硫有可能替代用于陰極的鈷,鎳和錳。

           

          以前,鋰硫電池的弱點與循環穩定性有關。這些問題已經在新型材料的幫助下得以克服,從而導致了利基市場中的商業化,例如在需要大量能量密度的人造衛星中。結果,一些已經存在一段時間的參與者看到了市場增長的復蘇。例如,Oxis Energy六年來首次獲得2018年的第一筆股權融資。

           

          商業化時機

          在許多情況下,五年內實現商業化的希望似乎過于樂觀。但是,隨著過去幾年我們所涵蓋的行業內出現大量后期融資的趨勢呈上升趨勢,在接下來的12個月內,新興的電池技術領域將會出現更多的重大投資,這不足為奇。幫助死亡的商業化谷底。

          Battery Technology Show Recap: Emerging Battery Technology

          Contributions from: Pirmin Ulmann, co-founder and CEO at b-science.net

          Last month, I was fortunate enough moderate a session at the Battery Technology Show in London. Here are takeaways from that session as well as some additional insight from our own research.

          Delegates from across the battery industrial supply chain participated in discussions around the technologies and business model innovations that could disrupt their markets in the next few years. Speakers included topic experts like Billy Wu, a senior lecturer at the Dyson School of Engineering at Imperial Collage, and Pirmin Ulmannm, co-founder and CEO of b-science, an energy storage patent search and monitoring company.

          Coming away from the event, I had the feeling that industry consensus is that the liquid electrolytes battery market share will rapidly drop due to the advent of a newer battery. The difference in views was the timing to commercial availability.

          Liquid lithium-ion performance has iteratively increased since its commercial introduction in 1991. Only in the last few years have major technological advancements, driven by large R&D funding, reached a tipping point of alternative battery chemistries. Venture capital has taken notice and increased investment activity over the past 24 months in solid-state, ultracapacitors and redox flow batteries, as well as driven a resurgence of investment into chemistries including zinc, sulfur and lead (shown in Figure 1).

          The panelists also provided insight into where some of these technologies stand today.


          Figure 1 shows the investment trends across emerging battery technologies

          Solid-state batteries

          As the name implies, solid-state batteries utilize a solid material to enable transport of lithium-ions in a battery. Solid-state batteries previously fell short of expectations due to lack of a suitable candidate materials for the electrolyte. Recent incremental gains at lab level have led to various successful pilot projects. The panelists explained that while Li-ion batteries with liquid electrolytes are the standard today, a solid electrolyte is non-volatile, making solid-state batteries inherently safer. They also have much higher energy density.


          Figure 2 shows a solid-state battery system

          In February 2018, automotive OEMs including Renault, Nissan, Mitsubishi and also Dyson collectively invested $65 million in solid-state battery startup Ionic MaterialsSolid Power also raised $20 million in preparation for a 2019 production facility and has prepared for maintainable growth with a set of strategic partners. QuantumScape received $100 million from Volkswagen in June, which took the company to early “unicorn” status, despite not having evidence of a commercialized product.

          The panel summarized that solid-state batteries maybe be over-hyped, and they will watch for under-performing technological gains, creating opportunities for alternative approaches to solid-state batteries even after wide-scale deployment. A recent example can be seen with Dyson’s acquisition of solid-state battery developer Sakti3 for $90 million a few years ago. The technology was planned for use in their electric car due for release in 2020. However, since the acquisition, the company has experienced a range of setbacks due to ongoing commercialization challenges, resulting in Dyson writing down the subsidiary’s value by $58 million.

          Current trends for long-duration storage

          Supercapacitors, otherwise known as ultracapacitors, were one of the promising technologies discussed. They offer much higher cycling stability (millions of cycles), compared Li-ion batteries at the expense of lower energy density. One discussion centered on the possible integration of both supercapacitors and solid-state batteries. In a combined solid-state battery/supercapacitor system, weaknesses in longevity and peak power performance of the solid-state battery can be compensated by the supercapacitor.

          Graphene derivatives and carbon nanotubes can improve the performance of supercapacitors and are increasingly being used at production scale. Early market player Skeleton Technologies is a manufacturer of graphene ultracapacitors, ramping up production to bring graphene ultracapacitors from high-end sectors to the mass market, while moving higher up the value chain with turnkey energy storage solutions.

          Sulfur in Li-ion batteries

          Lithium-sulfur was discussed as a promising battery technology with recent substantial R&D activity by key industry players. Because of its high energy density and availability, sulfur could potentially replace cobalt, nickel and manganese for use in the cathode.

          Previously, the weakness of lithium-sulfur batteries was related to cycle stability. These issues have been overcome with the help of novel materials, leading to commercialization within niche markets such as in satellites that require high energy density on a mass basis. As a result, several players who have been around for a while are seeing a resurgence in market growth. For example, Oxis Energy  for the first time in six years, received a first portion of equity funding in 2018.


          Commercialization timing

          Hopes for commercialization in under five years in many cases seems over optimistic. But with an increasing trend of substantial late-stage rounds appearing within the sectors we cover over the last few years, it wouldn’t be surprising to see a few more major investments cropping up within the emerging battery technology space in the next 12 months to help with the commercialization valley of death.

          Be sure to keep an eye out for any new battery emerging technologies activity on our i3 platform.
