Electric Vehicles:Batteries and recycling
Watched a video about the nissan leaf battery pack being disassembled, and was surprised to see what was actually inside of the 48 "sardine can" modules, when the youtuber sliced one open with a can opener...literally
I half expected to see a collection of "little" conventional looking batteries inside the tin but no.....this
Looks like a bunch of envelopes inside plastic pockets. There are 4 separate "cells" in the bundle.
Now inside the steel tube of a Panasonic 18650 Cell widely used in TESLA battery packs there is a curled up matrix of layers bundled up inside a small tube, rather than being laid out in a large sheet within a sardine tin.

Re: Electric Vehicles:Batteries
This article from electricbike has probably more information on the 18650 Battery than you are ever likely to need but quite interesting with pics links and diagrams not just specifically for building custom bike packs
https://www.electricbike.com/inside-18650-cell/
I'm sure if you want to spend time watching the 3 videos of the cut up of the Nissan leaf battery pack, you will be able to find them on you tube.

Re: Electric Vehicles:Batteries
EU approves €3.2-billion project to create more sustainable Li-ion batteries
The completion of the overall project is planned for 2031......
By the time that arrives who knows Li-ion may be obsolete.

Whatever happened to IBM?
Well they have turned up with a bit of battery research, what next they will take over the world with the IBM PC? (Personal Car )

Even more interesting!

Re: Electric Vehicles:Batteries
Couple of battery stories today concerning our German friends.
Volkswagen appear to be serious about carving out their share of the EV market, but the more reluctant BMW appear to be interested in at least securing their position, without 100% joining in.
BMW revamps battery materials supply chain, signs supply contract for raw lithium
Volkswagen acquires 20% of Chinese battery maker Guoxuan

Re: Electric Vehicles:Batteries
Link to Simon's Post on PSA/Saft announcement of plans for 2 European li-ion battery factories
So who is going to build the first of the UK's battery gigafactories? Ever Ready, Crompton Parkinson, the traditional car makers.......none of which are british owned, the Chinese, South Koreans or is someone going to roll the red carpet out for TESLA, or maybe Nissan will rise from their complacent slumbers and build on what they already do at Sunderland, or just let that wither away and retreat back to Japan.
Its better to be optimistic and positive, and some major shift is required to kick start....er this is the modern world...electric charge the new industries. I do not see an automotive company currently producing vehicles in the UK who will take the lead in this, with their parent companies with loyalties elsewhere.

As if to prove my point here's the first line of the article posted by Simon re PSANewcastleFalcon wrote: ↑03 Feb 2020, 13:57 I do not see an automotive company currently producing vehicles in the UK who will take the lead in this, with their parent companies with loyalties elsewhere.

"Two plants - first in France and the second one in Germany - with a total of 48 GWh of installed manufacturing capacity. "
So thats Opel and mainstream PSA covered.....and a big chunk of "European combined state aid" from the EU for the €5 billion investment, supported by nearly €1.3 billion in public funding from the European Union.
Yes and the French State still have their stake in PSA.

Re: Electric Vehicles:Batteries
Tesla dont "make" their own battery cells, but partner with Panasonic to secure supply of the cells. "Tesla, said during last week’s earnings call that its agreements with LG Chem and CATL were of a smaller scale than the existing Panasonic partnership."

Re: Electric Vehicles:Batteries
There are some strange bedfellows in the globalisation of business.
Nissan's battery supplier is building its first factory in China. So who is Nissan's Battery Supplier....I thought it was.....Nissan....after all it has a battery factory in Sunderland.
Not so...Nissan decided to get out of the battery making offshoot Automotive Energy Supply Company, and sold it to Chinese renewable Group Envision.
So as well as Northumbrian Water being owned by the Chinese, even something as wholesome and British as the UK's only EV batterymaking factory in Sunderland is 100% owned by the Chinese.

In Aug 2018, Nissan announced it would sell its electric car battery unit to Chinese renewable group Envision Group, while retaining a 25% stake. The sale included AESC as well as battery manufacturing plants in USA (Tennessee) and England (Sunderland). NEC's 49% stake was also to be sold to Envision.
In April 2019 the company, announced plans to open a new 20GWh capacity battery plant in Wuxi, Jiangsu, China, roughly triple its production capacity of 7.5GWh/pa

Hold the front page Toyota are doing something....it will work on prismatic batteries they intend to sell to other automakers.

"Toyota and Panasonic announced this week they have formed a new partnership known as Planet Energy and Solutions. Toyota will own 51% of it while Panasonic will own the remaining 49%."
