Description
Technical field
This patent is a kind of high energy density cells, belongs to field of batteries.
Background technology
Lithium ion battery is widely used in the fields such as communication, illumination, energy storage, electric tool.Along with the development of lithium ion battery and the developing of application, some communicate, the performance requirement of lighting apparatus to battery is more and more higher.The energy density of the ternary material battery that current application is more is at about 180Wh/Kg, and other types battery energy density is higher relatively in the market.But, along with the development of the portable electric appts such as mobile phone, require higher to the continuous capability of battery.Thus need to develop more high energy density cells to improve the energy density of battery.
Summary of the invention
Technical problem to be solved in the utility model is, provides a kind of high energy density cells structure, solves the problem that current battery energy density is lower, and then adapts to require the higher equipment such as communication, illumination.
For solving the problem, the utility model adopts following technical scheme:
A kind of battery of high-energy-density, the aluminum plastic film of described battery positive plate, negative plate, barrier film and external packing, it is characterized in that, described positive plate is aluminium foil, negative plate is Copper Foil, described positive plate is divided into the lug district on top and the coating area of bottom, and described negative plate is divided into the coating area of ear lug district, top and bottom, and the coating area of described positive plate and the coating area of negative plate have uniform hole.
On described positive/negative plate, the area in the hole of coating area accounts for 20 ~ 50% of coating area area.
Advantageous Effects of the present utility model is:
(1) positive plate and negative plate adopt respectively and have cavernous aluminium foil, Copper Foil, add effective active matter content under equal volume state, improve the capacity of battery.
(2) due to the more difficult coating processing of cellular foil, lug district and coating area are separated, effectively can improve rate of finished products.
(3) owing to adopting loose structure, in injection process, be conducive to absorption and the maintenance of electrolyte, improve the infiltration electrolyte content of material, the cycle life of battery can be improved.
