Much has been made of the fact that Toyota is
seemingly behind
General Motors and other manufacturers in the race to adopt lithium-ion
batteries as the future battery of the hybrid and electric vehicle
market. Lithium-ion batteries pack more energy into less space than
nickel metal hydride batteries, which are the current industry standard
in hybrids. Could this delay in the adoption of lithium ion technology
be because they have
something better up their corporate sleeves for the next-next Prius? According to
reports from Japan, Toyota may be investing in
zinc-air batteries,
which are currently popular only in your grandpa's hearing-aid. If the
rumors are true, these new batteries would make up a big chunk of
Toyota's plan on offering a hybrid version of every car it sells
by 2020.
In the meantime, expect to see lithium-ion batteries in future Toyota
hybrid models until it's ready to unveil its newest battery technology,
whatever that may be.
