Energy and high rate performance propose higher requirement, high energy battery has turned into the focus on research direction of battery industry.
Lithium battery is divided into lithium primary cell（One-shot battery）And lithium ion battery（Secondary cell）.Comparatively, lithium primary cell
With higher energy density, mainly because it uses theoretical gram volume of the lithium an- ode than lithium ion battery using carbon based negative electrodes
Greatly, the theoretical gram volume of lithium an- ode is 3860mAh/g, and the theoretical gram volume of carbon based negative electrodes is 372mAh/g, but due to
Thin lithium an- ode is difficult to be made, therefore the power output of lithium primary cell is relatively low, and rechargeable lithium ion batteries usually can
Meet that electronic equipment for high-power requirement, is primarily due to the carbonaceous material that its negative pole is strong electric conductivity, and utilize coating
Mode adhere to the adjustable active material of a layer thickness on negative current collector, and increase is being just by way of winding or lamination
The area of cathode contact, so as to improve the power density of battery.But theoretical gram of its carbon material used as anode of rechargeable lithium ion batteries
Capacity is relatively low, and in the structure of traditional lithium-ion battery, although improving the power density of battery using the mode of winding or lamination,
But reduce the energy density of battery, thus the structure of conventional rechargeable lithium ion batteries be unfavorable for improve battery energy it is close
Degree.
