  • Battery Technology Show in London - 2018-11-13

  • Louis Brasington from the Cleantech Group has written an excellent recap of discussions at the Battery Technology Show in London, which highlights promising technologies and startup companies.
  • The Battery Show North America - 2018-09-15

  • Booth visitors from battery, automotive & aerospace companies have been very interested in our strategic energy storage patent review & in our ML-based patent search tools.
  • It has been recognised that currently 'hot technologies' with wide trade press coverage - such as the adoption of solid-state batteries - have been well visible in the patent literature since before 2014.
  • Even newer technologies - such as Li-sulfur / Li metal containing batteries - are already investigated intensively according to our patent literature studies while the trade press is largely silent about these topics.
  • Strategic Patent Review - Supercapacitor Module - 2018-09-07

  • The 124 page supercapacitor module contains IP radar diagrams for 109 companies or alliances.
  • Correlations between capacitor type (EDLC, asymmetric & symmetric hybrid capacitors) and application type are identified.
    A gradual shift in patenting activity towards symmetric hybrid capacitors has occured, while substantial improvements in energy density are claimed for EDLC cells.
  • 82 technology stacks have been identified for 51 companies or alliances, which represent an assembly of patent families that likely define a current or future product (material, cell or module).
  • >70 links to company product pages are provided.
  • The strategic discussion explains why the combined adoption of supercapacitors with solid-state/gel Li-ion batteries is a likely future scenario.

  • China International Battery Fair (CIBF) - 2018-05-26

  • With 1,250 exhibitors and ca. 40,000 visitors, the CIBF has been a tremendous opportunity to learn and engage with new and existing contacts. We thank the organisers for providing us with a favorable exhibition space in Hall 1.
  • On the streets of Shenzhen, it was apparent how electric vehicles have become increasingly abundant as compared to prior visits. This subjective impression is consistent with the fact that Shenzhen is the first city in the world that replaced its whole diesel bus fleet with electric buses.
  • After demonstrating a summary of our strategic energy storage patent review to a three figure number of visitors at CIBF and The Battery Show Europe, we can state that individual visitors from large and small industry players confirmed our findings are of high interest and granularity. Nobody contested our observations, which we think further supports the validity of our machine learning based approach towards the global energy storage patent literature.
  • The Battery Show Europe - 2018-05-18

  • The number of exhibitors at The Battery Show Europe in Hanover (Germany) more than doubled since last year to more than 300 organisations mainly from Europe, Asia and North America.
  • A lot of fundamental questions have been discussed as to how the European energy storage industry should look like in the future and what steps have to be taken.
  • Visitors to our booth have been very interested in the technological trends we identified with our machine learning based analysis of the patent literature.
  • They appreciate that we can plot how the R&D agendas of major energy storage players differ substantially, for example in terms of their approach to different cell chemistries, such as liquid vs. gel vs. solid-based electrolytes in Li-ion cells, or in terms of their approach to Li-sulfur batteries.
  • seif impact academy - 2018-03-23

  • During the next five months, we will participate in the Zurich-based seif Impact Academy, which supports impact enterprises during the growth phase. Our coach is an IT security executive from the Swiss financial services industry.
  • Making technology less manipulative - 2018-03-09

  • In this thought-provoking Stanford Entrepreneurial Thought Leaders presentation, Tristan Harris (Time Well Spent) explains how Internet businesses that finance themselves through advertising employ machine learning techniques to attract users to spend as much time as possible on their site.
  • According to Tristan, if a user pays for a service on the Internet, the interests between the user and the service provider are better aligned towards solving a problem within the shortest time possible.
  • As it is our purpose to facilitate energy storage research, our target is that users spend as little time as necessary on our site to increase innovation productivity. Consequently, it is our intention to finance ourselves through user contributions rather than through advertising.
  • A new era for energy politics - 2018-02-02

  • At this insightful panel discussion at the World Economic Forum Meeting in Davos, it became apparent how a number of simultaneous technological, economic and political developments have generated an irreversible trend towards an electrified energy landscape based predominantly on solar power and electrochemical energy storage.
  • 1) Solar power has become the most competitive way to produce electricity in most areas and allows addressing the issues of climate change, air pollution, energy independence, and economic competitiveness.
  • 2) The electrification of automotive transport is the only feasible way to address inner city pollution. Because this problem is most acute in emerging countries, these countries are leading investments into next generation industries that will push fossil technologies into niche applications across the globe.
  • 3) Digital technologies accelerate these trends and allow for additional efficiency gains.
  • Commercialization of battery materials - 2017-11-12

  • A recently published article by Prof. Vinayak Dravid from Northwestern University and coworkers very nicely illustrates the challenges of converting battery-related inventions demonstrated at the R&D bench level to real life applications. A systematic framework is proposed based on observations from the pharmaceutical industry. Because battery performance is typically limited by interface effects, it is important to emphasize that the more different material combinations are tested at each successive technology readiness level, the higher the likelyhood that a battery material will be incorporated into a real life system.
  • The Battery Show North America in Novi (MI), USA - 2017-09-17

  • Attendance at The Battery Show North America grew by more than 15% compared to 2016. Despite the rapid growth of this industry, the mood cannot be characterised as exuberant, presumably because of increasing competition along the battery supply chain.
  • Our booth was well-frequented by visitors who are interested in achieving better situational awareness in the rapidly evolving battery technology sector by identifying relevant patents and technological trends across the globe with the help of machine translations and machine learning.
  • Which metals are used in batteries? - 2017-09-03

  • Our database allows us to answer this question in a convenient and forward-looking manner. A keyword search (title or abstract) in patents published this year shows that in 41% of metal- or metaloid-related patents, lithium is mentioned. Lead follows with 11%.

    Metal type in batteries

    Silicon is ranked third with 6%. The graph below demonstrates that silicon is patented much more frequently in batteries nowadays as compared to the years 2001 and 2010. A further analysis aided by machine learning models that identify relevancy with respect to Li-ion battery cathodes and anodes shows that a good part of the reason why silicon is mentioned more often is its relevancy with respect to negative electrodes of Li-ion batteries. A relevancy score of 30 (100: highly relevant, 30: relevant, 0: not relevant) has been used as a cut-off in the graphs below.
    Although aluminum is also relevant to Li-ion battery electrodes (especially cathodes), it is patented more often in other contexts in the battery field, such as packaging.
    For nickel and iron, an increase in patenting activity can be observed and these metals remain highly relevant to Li-ion battery cathodes.

    Trend metal type in batteries Si, Al, Ni, Fe

    An increasing number of patents can also be observed for copper, but not specifically in relation to Li-ion battery electrodes.
    Manganese and cobalt are confirmed to be of very high relevance for Li-ion battery cathodes, which is the context in which they are typically patented in batteries.
    On a relative basis, zinc is being patented less frequently in relation to batteries as compared to the year 2001, and its relevance with respect to Li-ion battery electrodes remains low.
