Introduction
to the Lithium battery
The proliferation of modern technologies,as well as the growing demand for unlimited mobility throughout society has created a boost in the demand for mobile energy stor-age systems and stimulated the phenomenal growth in the primary and rechargeable bat-teries industry. Portable electronic devices such as cellular phones, portable computers,video cameras and other consumer products require energy sources providing high ener-gy and power density.
Sustained demand for primary high-power battery has led to the development and production of the primary lithium bat-tery. Similarly, strong market drive for a safe and high-energy rechargeable battery has allowed the fast development and market acceptance of the lithium-ion (Li-ion) bat-tery technology.
In addition, OEM manufacturers of sta-tionary and automotive applications like hybrid electric vehicles, 42V-dual battery systems, as well as large sized batteries for telecommunications and space applications are intensively arching for battery tech-nologies with improved energy and power density as well as an extended cycle life. In the areas, lithium-ion battery is being a rious candidate.
学术水平For thermodynamic and kinetic reasons,lithium battery systems could meet the requirements for energy and power density for most battery applications in portable, sta-tionary and traction (HEV and EV) equip-ment.
Primary battery
Lithium metal is attractive as a primary battery anode material becau of its high specific capacity, high voltage, and good con-ductivity. Primary cells using lithium display superior performance such a
s high voltage of about 4 V , specific energy and energy density
Secondary and primary batteries - energy density and specific energy
two to four times better than conventional primary alkaline batteries, flat discharge curve, shelf life exceeding 10 years and wide operating temperature range.
In the positive electrode of primary lithium battery, carbon materials are mixed with active materials to provide the needed con-ductivity.
Secondary battery
As a material in the negative electrode,lithium metal is mainly ud in primary bat-tery systems, the reason being the limited rechargeability of metallic lithium for safety reasons.
The substitution of lithium metal elec-trodes with inrtion materials showing rela-
tively high lithium activities initiated the break-through for the rechargeable lithium battery, the so-called Lithium-ion, Swing, or Rocking-Chair battery. The first Li-ion bat-tery manufactured industrially appeared on the market in 1990.
Since then, this battery system enjoys a steady growth in demand compared with other rechargeable energy storage systems for the same fields of application. While offering remarkable safety, the Li-ion-system provides unique performance regarding high capacity,energy as well as power density, as the highly reactive lithium metal is bound in a carbon-electrode.

Carbon for condary Lithium battery
TI Conductive carbon black displays large surface area (50-770 m 2/g) and high structure due to aggregation of nano-sized primary par-ticles, while micro-sized graphite particles dis-play moderate surface area (5-25 m 2/g) and high anisotropy. The dimensions of the single crystal domains in the graphite particle are by more than a factor of ten larger than in a car-bon black particle resulting in complementa-
ry properties.
