The utility model discloses in, battery constant resistance discharges, under certain discharge condition, measures the quality of battery discharge performance with the battery discharge time length before specific final voltage (load voltage final value). In the discharge line, the following relationships exist:
V=I·R……(1；)
v: a load voltage;
i: operating current;
r: and (4) discharging the resistor.
The longer the battery can discharge, the more V can be supported by I.
In the battery, an anode is a donor electrode for electron flow, a cathode is an acceptor electrode for electron flow, the donor electrode provides electrons to flow through an external circuit to do electric work and is accepted by the acceptor electrode, meanwhile, under the influence of electron exchange between the acceptor electrodes, reaction products are reconfigured to maintain electroneutrality so as to meet the principle of energy minimization and enable the reaction products to exist stably.

The single electrode has no corresponding electrode conjugate and can not become a battery, and the negative electrode and the positive electrode can form the battery after conjugation.
The discharge performance of the battery is related to the characteristics of the single electrode in the conjugated electrode and also to the interaction between the counter electrodes. The increase in the electrode area is clearly accompanied by an increase in this interaction. This increase causes the electrodes to promote each other and the respective reaction depth to increase. The electrode reaction depth is increased, so that the discharge rate of the battery can be greatly improved in an unconventional manner, and the discharge performance of the battery is remarkably improved.
