Nissan Expected To Exit Lithium-Ion Battery Business - Will Likely Turn to LG Chem For Future Supply


Officially, the position right now for Nissan is no comment, but Renault-Nissan inside sources have told Reuters that Nissan will likely exit the business of battery making in the U.S. and UK as soon as next month.

Per Reuters (via Automotive News)




"Nissan boss Carlos Ghosn is preparing to cut battery manufacturing, people familiar with the matter said, in a new reversal on electric cars that has reopened deep divisions with alliance partner Renault."

"The plan, which faces stiff resistance within the Japanese carmaker, would see U.S. and British production phased out and a reduced output of next-generation batteries concentrated at its domestic plant, two alliance sources told Reuters."

It's further believed that Nissan would then follow Renault in securing batteries from South Korea's LG Chem (widely considered the world leader in lithium-ion automotive batteries).

Reuters quotes an executive on condition of anonymity as stating:

"We set out to be a leader in battery manufacturing but it turned out to be less competitive than we'd wanted. We're still between six months and a year behind LG in price-performance terms."

One of the other insiders is quoting as stating:

"Renault would clearly prefer to go further down the LG sourcing route, and the Nissan engineers would obviously prefer to stay in-house. The write-off costs are potentially huge."



The final decision on this matter is expected next month and will be made public at that time.

For now, Nissan spokeswoman Rachel Konrad offers these statements:

"[Renault-Nissan] remains 100 percent committed to its industry-leading electric vehicle program."

"We have not taken any decision whatsoever to modify battery sourcing allocation."
["the alliance] does not confirm or deny procurement reviews."

Reuters adds that the inside sources claim Nissan is negotiating a deal right now with batter partner NEC Corp. The deal would be some sort of dual source effort in which both NEC and LG Chem would supply Renault-Nissan batteries. Reportedly, LG Chem could set up shop within either the U.S. or UK Nissan sites to produces batteries at one of the two locations.

Renault-Nissan CEO Carlos Ghosn made this comments last week:
"We're in the process of opening up battery sourcing to a range of suppliers."




Ghosn admitted that "within the framework of alliance procurement" Renault-Nissan will likely outsource some battery contracts in the future. He added:
"What's important to us is that electric car performance fully meets customer expectations."

Of note: both the Renault Twizy and Renault ZOE feature LG Chem battery packs. Renault's tie with LG Chem dates back several years and recently Renault signed a joint agreement with LG Chem on next-generation batteries.

LEAF Battery Modules arrived from the US !

Ordered 10 days ago, 2 of the 4 LEAF Battery Modules arrived from the US, and I am very exited and happy to share this :-)



If you recall, Jack Rickard, on his EVtv January10th, 2014 show, unveiled a purchase of these same modules from a US based company, selling individual modules, used or new

The key figures of these modules compared to CALB LiFePO4 cells: 
 - Half price 
- 1/3 more Energy Density (= more energy in less weight and space)

So I immediately thought that they could be an interesting evolution for my Energy Storage System, the DIY ESS 

At the time I ordered, there were no more used ones, so I go the new ones  


I went to the post office to get these two packets, with my daughter


USPS Flat rate box holds two modules


Well packed with dense foam, here the are


Unfortunately, some corners got damaged and I was a bit concerned at first seeing this


Oops ..


Very first voltage check: 7.6V = 3.8V + 3.8V (4 pouch cells: 2 in Series, 2 in Parallel)


Others damages, to the back of the module also, but not much













There I started looking at how the pouch cells are arranged inside the modules, and if the impacts could have damaged the pouches ...














So, are these going to be a good fit inside the DIY ESS ?



Well, this looks good to me





And I should be able, if it all works out, to arrange two stacks of modules, side by side, in the battery section of the ESS, to the right



Finally I found this cutaway picture of the module, provided by Nissan, showing that at least the rear impacts into the module metal corners should not touch the pouches



The front one, should be fine too, because there is a hard black plastic protective shell




another back view








Front terminals: 7.6V between the two main ones, 3.8V between each main terminal and the center one; I also found out that only the copper part is conductive, not the the internal thread


Here they are now, downstairs, away from the kids ...



Stay tuned ... there are two more coming monday or tuesday, and I hope they will be fine ...

Local Sourcing of Materials for the Nissan LEAF Brings Costs Down






Even after Nissan moved assembly of North American LEAFs to Smyrna, Tennessee in late 2012, most of the high-value components for the vehicle still came from abroad.

But the Japanese company is moving forward to localize the production in the U.S. and provides us the example of sourcing magnetic wire for electric motors from Superior Essex, based in Fort Wayne, Ind. and magnets processed in Oklahoma.


What is interesting, according to Nissan, localizing magnetic wire supply took about two years. One year for the quality testing and a second year to set up thelogistics. By the end of this year, Nissan’s electric motor facility in Decherd will use only U.S.-made magnetic wire.
