What are nanotechnology batteries?
The so-called nanotechnology battery uses nanotechnology materials or
manufacturing processes in the battery manufacturing process to produce battery
products with particularly high performance. With the rapid development of
electronic technology, people's demand for batteries is increasing. People
always hope to get a battery with large capacity, high power, excellent
performance and low price. However, due to objective and practical limitations,
batteries in reality cannot always fully meet people's requirements. Experts and
scholars in the battery industry are tirelessly pursuing the improvement of
battery performance, and have experienced unremitting efforts from generation to
generation.
The emergence of nanotechnology and the successful development of
nanotechnology materials have shaken up the global battery industry, and experts
and scholars in the battery industry have seen a new hope. Various experiments
have been carried out in an attempt to comprehensively improve the performance
of real-life batteries. After thousands of tests of failure and success,
satisfactory results were finally achieved in a limited number of battery tests.
The battery performance has made great progress. Under normal circumstances, the
battery capacity can be increased by 10%-30%, the battery specific power can be
increased by 25%-35%, and the battery life can be increased by 40%-60%, making
the battery performance-price ratio Has been unprecedentedly improved. The use
of nanotechnology activation in the later stages of battery use can also extend
the service life of the battery.

Why do nanotechnology batteries perform so well?
At present, the application of nanotechnology in batteries mainly focuses
on the preparation of nanotechnology materials, the application of
nanotechnology materials in battery electrode manufacturing and battery
formation. When conventional materials are processed to the nanometer level,
their optical properties, thermal properties, electrical properties, mechanical
properties, chemical properties, etc. are significantly different from
conventional materials, and they have many unique characteristics and
application effects that conventional materials do not have.
First, nanotechnology materials have very large specific surface areas.
Because of its large specific surface area, it is extremely active. Its activity
mainly comes from the interaction of atoms on the surface of nanoparticles.
Atoms inside the material and atoms on the surface of the material experience
different forces. The atoms inside are in a mutual balance of various forces,
while the atoms on the surface of the material particles have extremely high
instability due to the presence of many dangling bonds. Due to its saturated
nature, it is extremely easy to combine with other adjacent atoms to form a
stable state, so it has extremely high activity.
Moreover, as the particle size decreases, the number of atoms on the
surface of the substance will increase sharply, so the activity of the substance
will increase sharply. Therefore, the smaller the particles of nanomaterials,
the higher their activity, and the characteristics of nanotechnology will be
more fully displayed. Secondly, since nanomaterials are generally tiny particles
with a certain charge, they can easily play an advantageous role under the
action of an electric field and form a new core of electrode reactions.
Therefore, for electrochemical reaction systems such as batteries, it is easier
to produce Strange effect.
When these nanoscale substances are used in battery manufacturing, they
will produce remarkable properties. With strong specific surface active energy
and good electrical conductivity, when participating in electrochemical
reactions, nanoparticle materials form new active material cores inside the
electrode plate, improving and enhancing the electrode structure, and greatly
improving the electrochemical reaction surface of the electrode. , lowering the
energy barrier of electrochemical reactions. Therefore, the application of
nanotechnology materials can significantly reduce the internal resistance of the
battery, inhibit the plate polarization caused by temperature and electrode
polarization during the charging and discharging process of the battery, thereby
effectively improving the performance of the battery and making the battery more
efficient. The electrochemical reaction is more reversible, the charge and
discharge efficiency is higher, the power is greater, the battery is easier to
balance and consistent, and the low-temperature performance limit is improved.
Therefore, batteries using nanotechnology materials have a higher capacity than
conventional batteries, a longer life than conventional batteries, a stronger
high-current working capacity than conventional batteries, and better
low-temperature performance than conventional batteries.
When and where are the main advantages of nanotechnology batteries?
In fact, the significant advantages of nanotechnology batteries are mainly
reflected in the middle and later stages of battery use. Generally speaking, the
initial improvement effect of nanotechnology batteries on capacity and power is
only 5%-15% of that of conventional batteries. The mid-term improvement effect
on capacity and power is 20%-30% higher than that of conventional batteries. The
later improvement effect on capacity and power is The effect is more than 50%
higher than that of conventional batteries.
