Electrification has expanded into the airline sector, which is the result of the attempted reduction of carbon footprint of the aviation industry, but it does open some interesting points for consideration. Currently, the aviation industry accounts for 2~3% of the total global carbon emissions.

BMW has patented a suspension system that can harness the movement of the suspension during vehicle operation to generate electricity. Although there seems to be no short-term application for this suspension system, the idea of increasing electric efficiency by diversifying regenerative charging schemes is notable.

Continuing from Part 2-1, Part 2-2 will be overviewing the Tesla open source patents dealing with controlling thermal runaway of its cylindrical cells and battery packs.

There is clear structure and intent to the Tesla pack design – it’s relatively straightforward without overly complex physical structures that may complicate manufacturing and/or serve as restrictions to parts supply. It’s evident from its beginnings and I’d like to focus on the safety aspect of the design in this Part 2 discussion.

Quite late to the party but in this series I’ll share and try to elaborate my thoughts on Tesla. In Part 1, I’ll discuss my personal thoughts on Tesla’s approach to the EV market and in Parts 2 and 3 I’ll try dive into the two aspects that I found most interesting – safety and battery control.

A light topic for discussion today – SWCNT as a conductive additive for lithium ion battery systems. It’s no new news that SWCNT or MWCNT are applied as conductive additives even in industrial applications as there has been numerous literatures that back up its effectiveness is improving the z-axis electron flow in both anodes and cathodes. The high aspect ratio of CNTs…

Solid state batteries (SSB) are very much the center of attention – it’s safer, has higher energy density, and can be the key to solidifying the position of LIBs for vehicle applications. The focus thus far seems to be on simply making SSBs that demonstrates good electrochemical properties at room temperature…

We all have had some experience with placing laptops or mobile phones under air-conditioning or even putting it on top of a bed of ice in a desperate attempt to cool the device down because instinctively we KNOW that hot electronics is bad. This is more so for Lithium-ion battery (LIB) systems…
