- Nissan sells its Battery manufacturing business to GSR Capital -- Preparing switch to LG Chem batteries? <p>Since launching the LEAF, Nissan's battery packs came from its subsidiary Automotive Energy Supply Corporation (AESC). That subsidiary is now being sold to GSR Capital. The deal is being spun as a win-win as GSR Capital has deep pockets necessary to develop this battery business faster than Nissan could. Supposedly.</p> <p>That might be accurate, ...or... It's long been rumored that Nissan wants to switch to LG Chem battery packs. If Nissan had switched to LG Chem batteries by now, the 2018 Leaf (due to be released soon) might have had a 200+ mile range with a 60 kWh pack. Instead the 2018 Leaf is rumored to have a 40 kWh pack which would give a respectable-but-not-competitive 150-180 mile range.</p> <p>According to CleanTechnica, <a href="https://cleantechnica.com/2017/08/03/nec-exiting-battery-business-likely-selling-division-chinese-investment-group/">NEC also sold its portion of this business to GSR Capital.</a> According to <a href="https://asia.nikkei.com/Business/Companies/NEC-exiting-lithium-ion-battery-race-as-leaders-pull-away">Nikkei</a>, where Panasonic had a growing EV battery marketshare due to its partnerships with Tesla and Toyota and others, NEC relied on Nissan and Nissan is looking to broaden its battery supply chain. </p> <p>Nissan originally built batteries in Japan. With the shift to localized Leaf production in 2013, Nissan launched battery factories in both England and Tennessee. The original vision was that owning the battery factory would give Nissan an economic/price advantage. One supposes that would have only held true if Leaf sales had risen enough, but instead Leaf sales have held steady for several years.</p> <p>In any case, the Renault side of the Nissan-Renault alliance already uses LG Chem batteries. That partnership has been very good for adoption of the Renault Zoe in Europe. A Leaf with better batteries should sell very well.</p>
- Toshiba Develops Next-Generation Lithium-ion Battery with New Anode Material The battery-breakthrough-of-the-week comes from Toshiba. They're announcing an update to the SCiB battery using a new battery anode doubling the storage capacity of the batteries. Energy stored (kiloWatt-hours) per unit of volume is double that of the previous generation SCiB, and the maximum recharge rate is high enough to support a 6-minute recharge time. They claim the battery can withstand 5000+ discharge/recharge cycles while retaining 90% of its original capacity, and that it works well in cold weather. If all this pans out it can be a real game changer in the electric vehicle industry, as energy storage capacity and recharge time are key concerns. On the other hand a 6 minute recharge time is unlikely to be implemented for the general public because it requires a 500 kiloWatt or more charging station.
