Nowadays,
countries
are
eager
to
get
more
electric
cars
on
the
road
because
moving
away
from
gas-powered
vehicles
is
vital
to
fighting
climate
change. China
says
that
most
new
vehicles
sold
by
2035
will
be
electric. The
United
Kingdom
will
ban
new
gas-powered
cars
in
2030.
One
of
the
worlds
major
automakers,General
Motors
(GM),
announced
that
it
would
stop
selling
gas-powered
cars
by
2035.
The
key
to
an
electric
future
is
batteries.
Automakers
are
racing
to
pack
the
most
energy
into
the
smallest
one. The
lithium-ion
battery
is
what
powers
our
mobile
devices,which
can
be
recharged
again
and
again. Making
these
batteries
has
an
environmental
cost. Lithium
is
taken
from
the
earth,like
the
oil
used
to
make
gasoline. But
the
long-term
cost
is
much
smaller.
“Once
you
burn
gasoline, you
cant
recycle
it,”
says
Jessika
Trancik,a
researcher
at
the
Massachusetts
Institute
of
Technology.
“But
when
you
use
up
a
battery,
you
can
still
recycle
the
material. ”
Its
up
to
governments
to
make
electric
cars
accessible
to
everyone. National
policies
can
help.
In
the
United
States,an
electric
Chevy
Volt
costs
about
$ 35,000. Trancik
says
charging
stations
must
also
be
made
widely
available. As
part
of
an
effort
to
fight
climate
change, America
plans
to
build
half
a
million
of
charging
stations
in
the
US
by
2030. She
hopes
enough
charging
stations
will
be
built
soon.
“ Its
important
to
put
chargers
where
many
different
people
can
have
access
to
them,”
she
says.
“Not
just
