Electrovaya Working With Wal-Mart: Can Lithium-Ion Replace Hydrogen/Fuel
Cell And Lead-Acid Battery For Mobility In The Warehousing And Distribution
Industries?

Summary
The efficiency of a fuel cell is very low ( ~22%) compared to a
lithium-ion battery (Electrovaya) which is ~ 92%.
The fuel cell as “the future” of the auto industry never realized -
lithium is the incumbent now and powers millions of electric vehicles from
Tesla, Nissan and others.
Electrovaya is the only manufacturer that does not use toxic chemicals
in manufacturing its batteries, resulting in a lower cost, safer product;
also contributes to preserving company shareholder value.
Wal-Mart, the world’s most sophisticated distribution company, is now
working with Electrovaya to develop lithium-ion battery power for its
forklift trucks, enabling higher productivity, fast charging and three-shift
operation.
Electrovaya's lithium-ion batteries are less expensive than a fuel cell,
replacing the need for hydrogen storage with the existing, well-established
electric grid.
Recently, Electrovaya announced that it is working with Wal-Mart and others
in the distribution and warehousing field by supplying its lithium-ion
batteries for forklift truck propulsion. This industry, which is driven
towards productivity, until recently was controlled by lead-acid batteries
to power its electric forklift trucks.
The limitations of the lead-acid battery are legendary so that recently
there was a move by Plug Power to replace lead-acid with their fuel cell.
So, the key question is whether Electrovaya's lithium-ion battery offers a
superior performance and can displace both fuel cells and lead-acid battery
power?
There are several reasons why Electrovaya's most recent V2.0 SuperPolymer is
superior to both of these alternatives.
1. Efficiency
Lead-acid battery problems of low efficiency, voltage drop, low cycle life
and long charging time add to the environmental challenges of hydrogen, acid
and lead in the environment.
In the case of fuel cells, poor energy efficiency is a fact of life. The
various steps in the well-to-wheel cycle, including electrolysis,
transmission and conversion via the fuel cell causes energy losses so that
typical round trip efficiencies barely exceed 20%.
2. The Production Process ... [*Register to read more]
