* South Korea's Kokam to supply batteries
* Demonstrator to make first flight by end of year -CEO
* Airbus, Boeing, Uber also examining electric technology

SINGAPORE, Feb 15 (Reuters) - Electric airplane start-up
Eviation Aircraft Ltd is aiming for its 9-seat commuter aircraft
to be flying passengers by 2021 after signing up South Korea's
Kokam as its battery supplier, the Israeli company's chief
executive said on Thursday.
Venture capital-backed Eviation is one of a number of
companies looking to develop small electric aircraft that would
incur lower energy and operating costs, release less emissions
and be quieter than their conventionally fuelled counterparts.
Airbus SE AIR.PA , Boeing Co BA.N and Uber Technologies
Inc UBER.UL are also investigating electric and hybrid
aircraft technology.
Eviation CEO Omer Bar-Yohay said his firm signed a deal with
Kokam last week because, as a smaller supplier, Kokam was able
to make batteries more specific to his company's needs.
"If I would go today to Samsung or Panasonic or LG Chem or
Tesla for that matter and say I need a different cell size, they
will probably laugh because the number of cells we are going to
buy is not significant enough to start the design process," he
told Reuters in a phone interview.
The battery will have 9,400 cells distributed throughout the
aircraft including the ceiling, floor and wings, weighing 3.8
tonnes, or 60 percent of the maximum takeoff weight.
Electric airplanes are reliant on improvements in battery
technology, which is why smaller aircraft are likely to be
electrified years before large commercial jets.
Batteries are heavy and store far less energy per kilogram
than jet fuel, but the ratio is improving gradually each year,
allowing electric cars and airplanes longer ranges than they had
previously.
Eviation's "Alice" airplane is expected to have a range of
up to 650 nautical miles (1200 kilometres), compared to 1000
nautical miles for a similar-sized conventional Cessna Caravan.
It will cost $2 million-plus, on par with the Cessna, but have
far lower fuel and maintenance costs, Bar-Yohay said.
Eviation hopes to fly the Alice demonstrator for the first
time by the end of the year, with the first public display at
the Paris Airshow in mid-2019, he said. Moving to commercial
production after that would require raising around $100 million
of capital.
Given the advantages of going electric, major manufacturers
are also investing in electric and hybrid aircraft technology.
Seattle-area startup Zunum Aero, backed by the venture
capital arms of Boeing and JetBlue Airways Corp JBLU.O ,
announced plans in October to bring a 12-seat hybrid-electric
commuter aircraft to market by 2022. urn:newsml:reuters.com:*:nL2N1MG1HZ
Airbus is working on the CityAirbus concept, a
four-passenger electric aircraft capable of vertical takeoffs
and landings, with the first demonstrator flight expected later
this year. Ride-hailing firm Uber is exploring a similar concept
with Uber Elevate. urn:newsml:reuters.com:*:nL4N1HX5DG
