Also, I wonder how
different battery chemistries compare in energy to manufacture.
Not exact matches
Mr Musk said the carmaker had reduced the amount of cobalt in its Nickel - Cobalt - Aluminium
battery cells produced by Panasonic below rival
battery companies who use a
different chemistry.Korean
battery companies such as LG Chem and Samsung SDI, who produce Nickel - Manganese - Cobalt
batteries, are expected to commercialise a lower - cobalt
battery chemistry by next year.
While it is certainly great at charging lipos, you can also use it for
batteries with
different chemistries.
The basic concept should work with many
different chemical compositions for the
different parts of the
battery, he says, but «we chose to demonstrate it with one particular
chemistry, one that we understood from previous work.
Manthiram said he is also investigating other
battery chemistries, like lithium - sulfur and sodium - ion, which use
different materials and offer their own advantages.
«This opens a broad window into many
different topics in electrochemistry, including sodium - ion
batteries, lithium - sulfur
batteries, multiple ion
chemistries involving zinc and magnesium, or even electroplating and electrochemical synthesis; we just have not fully explored them yet.»
Batteries of
different ages, or with
different chemistries and internal surface areas will perform differently (and nor would you want to completely discharge a car
battery, as they are not meant for «deep cycling»).
Unfortunately this is not the case... Not only the plug is
different, but also charging voltage / current, the
chemistry of the
batteries and thus the charging method etc..
The carmaker plans to upgrade the
battery packs with cells that use a
different lithium - ion
chemistry before the vehicles go back into service.
But given that cobalt isn't necessary to LI tech — as stated in the article Killian linked, the Chinese auto giant BYD for instance uses a
different chemistry for its cathodes, and so doesn't need cobalt for its
batteries — lithium seemed to me a better choice for our purposes here.
We had in fact encouraged GM to start with a lower - range vehicle to use smaller, cheaper, or
different chemistry batteries.
It is also a bit of a
different challenge for Tesla, as it tends to be tougher to improve class leading
battery performance than catch up, and indeed much improvement for the NCA cells used in the Tesla S may require very new
chemistry.
Matt also has significant experience preparing and successfully prosecuting patent applications in many
different fields, including automotive fuel cells and catalyst systems, ecofriendly polymers,
battery systems, treated textile
chemistry, video surveillance technology, consumer electronics, computer software and database systems, and data processing systems.
The upshot of all of this is Samsung was also forced to reevaluate how it designed and manufactured phone
batteries, and it now uses
different processes and
chemistries that produce more durable
batteries that also degrade less over time.
