ltra-mobile modern day lifestyle is critically powered by lithium ion battery (LIB). Since its discovery, it has
come a long way to revolutionize our society and redefine our civilization. It also has huge role to play in
replacing gasoline powered cars by electric cars and thereby reduce carbon foot print significantly and address a very
serious global concern. At this point, one can embark onto a completely new set of technology, for example, a metal-
air battery, which holds tremendous future potential but comes with serious technical challenges. However, it will be
more prudent both technically and economically to realize the full theoretical potential of LIB (we are nowhere close
there yet), before we change the bandwagon. Let us illustrate: pure lithium thus far could not be used as cathode in
LIB and silicon, which has long been predicted to be the best element as anode material, from a pool of candidate
elements spanning the entire periodic table, could not be used. Each silicon atom can theoretically hold on up to four
lithium atoms in contrast to 1/6th in case of graphite, another commercially popular anode material. In this study,
we focus on anode and demonstrate that how the major problems in realization of silicon anode (volume expansion
and kinetic sluggishness) can be resolved by using our novel heterostructured nanoporous silicon (HNPS). We will
discuss the protocol to obtain this novel HNPS from a low grade source material and compliment the understanding
by first principal studies proving both thermodynamic and kinetic insights. We demonstrate lithium ion half-cell
performance using HNPS. We further demonstrate the economic prudence (cost reduction by an order of magnitude)
in adopting this technology commercially by comparing to a latest-model Tesla® car as a reference point.
