    Safety Issues of Large-capacity Batteries
    For an energy system, the higher the power, the more dangerous it is. Lithium ion battery is a typical example. It is fantastic to raise its capacity and lower the danger factor at the same material.  Because current superimpose principle, rendezvous point of current superimpose is close to battery tab. This will lead to uneven current density o...
