The first
lithium ion batteries were brought to the market over a quarter century ago in
a camcorder made by Sony. Since then the
technology has gained widespread adoption for all sorts of electronic devices
and most importantly for electric vehicles. In 2016, lithium ion batteries were
sold with a total of 70 gigawatt-hours storage capacity, just over a third of
which ended up in electric cars. There are
plans afoot to eclipse that production level.
The top lithium ion battery makers are reportedly posed to expand manufacturing
capacity that together could triple production of lithium ion batteries within
the next couple of years.
Popularity
should not be confused for full satisfaction.
Battery manufacturers are under
pressure to improve performance. Higher capacity,
shorter charge time, slower discharge, and longer life and just a few of the
characteristics that electronics producers would like to get in the
battery.
Electric car
manufacturers are particularly sensitive to the need for smaller size and lighter
weight. The typical electric car battery
pack weighs between 200 and 250 kilograms (400 to 550 pounds), but the much
discussed Model S sports car made by Tesla
(TSLA: Nasdaq)
battery weighs 540 kilograms (1,200 pounds).
A lighter battery could lead to higher efficiency and longer drive times
between charges.
One of the most
recent battery recalls was made by Hewlett Packard (HP: NYSE) when in January
2018, batteries shipped with certain laptops and mobile workstations were found
to have a ‘potential to overheat’ and could be a fire hazard. Add better safety to the wish list.
Battery makers
themselves would like to perfect better designs that would require less
expensive components and materials. The industry is worried about the adequacy
of the current supply chain for the materials used in most lithium ion batteries. In particular cobalt appears to be in short
supply given planned expansion in lithium ion battery capacity. Most cobalt is sourced from the Democratic
Republic of Congo (DRC), where politics is often tumultuous if not
dangerous. In April 2018, the DRC
state-owned mining operation called Gecamines went to court to dissolve
its copper-cobalt operation with Katanga Mining (KAT: TSC) that is controlled
by Glencore
(GLEN: LSE).
The battery
industry has some answers. For example,
higher-voltage cathodes and anodes could boost lithium ion battery
performance. Improved electrolytes could
lead to a better safety profile. Performance
improvements could also reduce dependency on expensive, sort supply Alternatively,
battery manufacturers could scrap lithium ions altogether and hitch their
wagons to some other ‘ion’ workhorse.
Plans to create efficiency or improve alternatives
almost always spell opportunity for small, innovative companies. This post begins a new series on battery
technology. The posts will return to
battery developers that have been profiled before as well as look at new
players in the field.
