Description
Technical field
The utility model discloses a kind of lithium-ion battery with steel shell, belong to technical field of lithium ion.
Background technology
Lithium ion battery specific energy is high, becomes at present chemical power source the most easily, it has, and voltage is high, specific energy is large, discharging voltage balance, security performance are good, long working life, the advantage such as environmentally friendly.Along with the develop rapidly of current electronics miniaturization and microminiaturization, the research and apply of lithium ion battery is also more and more paid attention to.
The one of important of exploitation lithium ion battery is updating of battery structure, and box hat cylindrical lithium ion battery energy density is large, and especially volumetric specific energy is large, make efficiency is high, cost is low, but capacity relative is less, increases the capacity of box hat cylindrical battery, the volume of corresponding increase box hat cylindrical battery, namely increase core external diameter or increase core length, making imbibition ability in high-capacity cylindrical battery process poor, because core is tighter, electrolyte pole is not easily permeated, and battery performance is affected.Obtain that energy density is large, make efficiency is high, cost is low and the lithium ion battery that capacity relative is larger, can design and develop on battery structure.
Summary of the invention
For the problems referred to above, the utility model provides a kind of Novel steel-shelled lithium ion battery, when ensureing high-energy-density, high efficiency, low cost, improves the capacity of lithium ion battery.
