 PolyPlus Battery Company is a world leader in the development of next
generation
lithium metal battery chemistry. The Company recently developed
protected lithium
electrodes that are remarkably stable in most aqueous and
non-aqueous electrolytes.
These electrodes form the basis of a new class of batteries where the
lithium
metal
electrodes is electrochemically active, but chemically isolated
from the liquid
electrolyte.
Protected Li electrodes can be used in corrosive
environments including
acidic and basic
aqueous electrolyte and even in
seawater where conventional Li and
LixC anodes would
immediately
deteriorate.
Polyplus is developing Li-Sulfur, Li-Air, and Li-Seawater batteries based
on protected
Li electrodes. The projected energy density and specific energy
for Li-Air batteries is on
the order of 1000 Wh/l and 1000 Wh/kg. PolyPlus
intends first to commercialize primary
Li-Air batteries followed by the
introduction of secondary Li-Air chemistry. The Li-Seawater
battery is a
primary battery system intended for marine applications. The theoretical
energy desity for Li-Seawater is 9000 Wh/kg and 4900 Wh/l, and PolyPlus
expects to
deliver
cells with practical energy densities of 4000 Wh/kg and
2000 Wh/l.
