[资源] 两篇关于锂电池的综述性文章-- 讲述锂电池未来和挑战

两篇文章,
1.《Key+challenges+in+future+Li-battery+research》
Abstract:
Batteries are a major technological challenge in this new century as they are a key
method to make more efficient use of energy. Although today’s Li-ion technology has
conquered the portable electronic markets and is still improving, it falls short of meeting
the demands dictated by the powering of both hybrid electric vehicles and electric vehicles
or by the storage of renewable energies (wind, solar). There is room for optimism as
long as we pursue paradigm shifts while keeping in mind the concept of materials
sustainability. Some of these concepts, relying on new ways to prepare electrode materials
via eco-efficient processes, on the use of organic rather than inorganic materials or
new chemistries will be discussed. Achieving these concepts will require the inputs of
multiple disciplines.

2.《Lithium-Air+Battery--Promise+and+Challenges》
Abstract:
The lithium-air system captured worldwide attention in 2009 as a
possible battery for electric vehicle propulsion applications. If successfully developed,
this battery could provide an energy source for electric vehicles rivaling that of gasoline
in terms of usable energy density.However, there are numerous scientific and technical
challenges that must be overcome if this alluring promise is to turn into reality. The
fundamental battery chemistry during discharge is thought to be the electrochemical
oxidation of lithium metal at the anode and reduction ofoxygen fromair at the cathode.
With aprotic electrolytes, as used in Li-ion batteries, there is some evidence that the
process canbe reversed by applying an external potential, i.e., that such a battery can be
electrically recharged. This paper summarizes the authors' view of the promise and
challenges facing development of practical Li-air batteries and the current understanding
of its chemistry. However, it must be appreciated that this perspective
represents only a snapshot in a very rapidly evolving picture.
