The developmen nt of electric vehicles (EVs)
and elecctrical
energgy
storage (EEES)
has reqquired
the highe er energy de ensity of the Li-ion rechargeable
batttery
technollogy.
Howeever,
their ennergy
density is i limited be ecause the number n of Li-ions thatt
correspondd
to the nummber
of eleectron
charge ar re limited to be intercala ated in the pr resent solid ssolution
matterials
for annode
and cathhode.
The use of lithium metal m as ano ode and air as a cathode pproduces
an extremely hhigh
capacityy,
ten
times hig gher than tha at of the pres sent lithium ion battery. Although vvery
high eneergy
densitiees
are
achievable,
there are challenges associated with w the desiign
of a pracctical
Li-Air cell. Emplooying
an inorga anic solid ele ectrolyte wit th a thin and d dense mechhanical
propperty
is a keyy
to the desiign
of
the Li-Ai ir cell. The purpose of this t project is i to design a rechargeabble
Li-Air battery
and teest
its
electroch hemical prop perties includ ding voltage,
capacity, cyycle-life,
annd
rate capabbility.
1) Obje
T
Li + ectives
The first obje ective of this s research will
be to design
a testingg
battery cell
that uses a fast-
-ion conducting c solid electro olyte. Li metal m and aair
will be uused
as anoode
and cathhode,
respectiv vely, for the cell. The an node part of f the cell, whhich
consistss
of Li metaal,
should bee
well
designed d to protect it tself from being
exposed
to air and moisture diirectly.
The second objeective
of this re esearch will be focused on o the desig gn of the cathhode
part off
the cell, whhich
is compposed
of an aqueous a electrolyte
for r providing Li-ion conductivity,
carbon papper
for eleectron
conductiv vity, and a medium fo or the oxyg gen pathwayy.
The finaal
objectivee
will be too
test
electroch hemical prop perties of the e constructed d Li-Air celll,
including voltage, cappacity,
cyclee-life,
and rate capability. The compo onents of th he cell such as the aqueeous
electrollyte
and eleectron
conducto ors will be modified to o improve th he cell propperties.
Thhrough
this multidiscipllinary
research activity, stu udents will learn l the con ncepts behinnd
Li-Air annd
Li-ion baatteries
incluuding
how their r critical com mponents aff ffect their ele ectrochemicaal
propertiess
from both a mechanicaal
and
a chemic cal point of view. v
2) Resea arch Meth hodology
The stated objec ctives of the e research will w be achievved
through a number oof
interactivee
and

RA-2: Test T of the electrochemi
ical propert ties of the ceell
The electrochem mical proper rties of the test cell designed
in RRA-1
will bee
evaluated. . The
voltage, discharge, d an nd charge ca apacities of the cell willl
be the mainn
focus of innvestigation.
The
aqueous electrolyte, current coll lector (thick kness, surfacce
area, andd
type of materials),
cattalyst
material, and other cell c compon nents will be e investigateed
to producce
repeatablee
electrochemmical
data.
RA-3: Cell
optimiza ation and ev valuation
The promising cell component
materi ials to emerrge
from RRA-2
will bee
subjected to a
thorough h characteriz zation in term ms of their more detaileed
electrochhemical
perfformance
unnder
a
range of conditions. Electrochem mical charac cterization (inn
terms of eenergy
and ppower
densityy
and
long-term m cyclability y/stability) will w be made e using the mmore
interessting
materiaals
which emmerge
from RA A-2.
3) Team m Organiz zation
A multidisciplin
m nary team of f undergradu uate students,
three fromm
mechanicall

and
one from m chemistry will w be assem mbled to con nduct the prooject
under the supervission
of the MMURI

will wwork
closely with
students to guide them m in their ex xpertise area as.

4) Exp pected Out tcomes
The outcome o of this project will be the design of a rechargeabble
battery ssystem
to tesst
the
effectiven ness of air as a a cathode e and lithium m metal as an anode. IIt
is anticipaated
that thee
cell
develope ed in this pro oject will pro oduce a volta age of ~ 2.5 V and a largge
capacity oof
~ 5000 mAAh/g,
which is more than te en times larg ger than the capacity of tthe
present llithium
ion bbattery.
Thee
high
energy density d Li-Ai ir battery co ould be used d in the electtrical
energyy
storage forr
next-generration
electroch hemical devi ices. Howev ver, the com mmercializatiion
of Li-Airr
battery tecchnology
reqquires
further re esearch and developmen d nt in solid ele ectrolytes annd
their cost and mechannical
propertiies.
5) Ben nefits
We anticipate a tha at the results s of the prop posed researcch
project wwill
be used bby
undergraduate
students to learn th he chemistr ry, electroch hemistry, annd
engineerring
design of recharggeable
batteries by collabor rating with an a interdisci iplinary reseearch
group. . Further, tthey
will become
scientific cally productive
by und dertaking the ese research activities. Thus, at leaast
one scieentific
paper wi ill be co-aut thored by th he students, and they wiill
gain expeerience
of RR&D
in the “real
world”. This will no ot only bene efit them in their future career but also motivatte
them to aattend
graduate school. The T success of this research
projecct
will provvide
a new direction foor
the
ongoing Li-ion batter ry research at a the Lugar Center for RRenewable
EEnergy
in ouur
