Looks like an analysis of the global battery industry, with the 2013 version presented at the 2013 Battery Japan conference.[1] From other citations I found[2][3] it's clear the speaker is Hideo Takeshita, who in 2001 was the vice president of IIT (the Institute of Information Technology Ltd.)[4] and in 2014 was the president of a battery market research firm called B3 Corporation.[5] Sure the document isn't freely available online, but given the commercial nature of the content that hardly seems suspicious. >your own sources contradict each other Sorry, I should have been more clear. It gets very confusing since it's a moving target, and you can rarely tell who is using what source (and when that source is from). The original capacity announced in their blog post[6] on 2014-02-26 was 35 GWh/yr at the cell level and 50 GWh/yr at the pack level (importing 15 GWh/yr of cells).[7] That's what you're seeing on the chart. Later at the 2016 shareholder meeting on 2016-05-31, Tesla CEO Elon Musk announced that they were going to triple the final production capacity at the Nevada Gigafactory.[8] [1] https://web.archive.org/web/20130207162628/http://www.batteryjapan.jp/en/Home/ https://web.archive.org/web/20130207162628/http://www.batter...
