ionic lithium battery has become an indispensable component in a wide variety of devices and vehicles
ranging from laptops and cell phones to hybrid and electric cars. Their
advantages range from their high energy density, rechargeability and
light weight (up to 70% lighter than lead acid batteries); increased
safety without producing toxic byproducts like lead acid batteries do;
furthermore they do not produce toxic byproducts like lead-acid
batteries do; thus their manufacturers work tirelessly towards
developing better cathode/anode materials, solid electrolytes that
ensure high capacity batteries for safe usage within batteries - just to
maintain these advantages!
Recent innovations include an ionic lithium battery that utilizes poly(ionic liquid) as its electrolyte
instead of using volatile organic solvents such as cobalt in current
LIBs as electrolyte material. This revolutionary development promises
higher energy densities at lower costs with reduced dependence on
expensive and troublesome metals such as cobalt found today's LIBs.
ionic lithium batteries consist of an anode, cathode, separator and electrolyte; with
the anode storing lithium ions while the cathode acts as an electron
storage space; while a separator blocks electron flow within the
battery. Finally, an 12 volt 20ah lithium battery electrolyte transports positively charged lithium
ions between anode and cathode during discharging and back to anode
during charging through intercalation/deintercalation processes that
take place simultaneously - this process is known as
intercalation/deintercalation in technical terms.
An anode typically composed of graphite material is combined with a cathode made
of nonflammable metal sulfides or nitrides to store lithium ions through
intercalation, where they are physically embedded between 2D layers of
carbon that make up bulk graphite, for storage purposes. Cell discharge
involves an anode that undergoes an oxidation half reaction that
releases positive lithium ions while simultaneously creating negatively
charged electrons through external circuitry; during discharge the anode
undergoes an oxidation half reaction that produces positive lithium
ions while negatively charged electrons are carried through external
circuit to cathode where reduction half reaction takes place and
electrical current flows through external circuit.
There are many kinds, such as 72v lithium ion battery, 12 volt 20ah lithium battery,
20ah lithium battery. Oxidation-reduction reactions must take place at optimal
temperature and conditions; otherwise, significant structural changes
could reduce battery capacity significantly and lower its cyclability
(the measure of how many charges and discharges a battery can handle
before its capacity begins to diminish), potentially increasing cell
internal pressure posing safety threats to mobile devices like tablets
and smartphones.
