Description
Technical field
The utility model belongs to the battery terminal technical field, is specially accumulator electrode with internal particle movable.
Background technology
Existing storage battery comprises the electrode of a pair of internal storage battery that is fixed: negative electrode (positive pole) and anode (negative pole), the discharge of this storage battery and the charging course of work are between this a pair of electrode oxidation and reduction reaction to take place respectively, in discharge process, the oxidized electronics that loses of anode, negative electrode is reduced and obtains electronics, and in charging process, this reaction is converse.In case after the process of charging is finished, enter the process of putting charging of next round again, the work period of finishing battery by this.Production of storage battery at present and use all are fixed on the traditional mode of internal storage battery at the electrode of following internal storage battery, the pair of electrodes of storage battery is forever to be installed in the cell body under this pattern, and certain limitation is arranged, and shows as:
One, charging and discharging efficiency instability during battery uses.Efficiency for charge-discharge, the useful life of people in order to improve battery electrode, constantly improving material and the production technology of making electrode always, but the battery production technology does not break away from all the time and is confined to install and fix electrode in battery, and this design cycle of charging-discharge is not left and is confined in the battery use all the time.Battery in continuous use, inevitably electrode can wear out gradually, charging times with charge efficiency can be inversely proportional to, along with the wearing out of battery, the charging interval can more and more be grown and charging and discharging efficiency can be more and more lower.And limit when the charging interval of storage battery is also by deisgn product under this pattern and be fixed up, people are in order to shorten the charging interval, to prolong discharge time, exploring always and attempting electrode that uses new material to serve as storage battery and the manufacture craft of improving electrode, and at every turn in charging interval stage, breakthrough the shortening, the cost that improves charging and discharging efficiency often: raising materials used cost or cost of manufacture, increase volume or weight are realized.Key to the issue is that design concept is not jumped out the inertia that installs and fixes electrode and set this intrinsic thinking of constant parameter of charge in batteries time in storage battery all the time.
Two, the charging interval is long and unalterable.Because the charge in batteries time under the technology is grown partially and immobilizes at present, there is the storage battery of particular requirement the charging interval at some, electric automobile as having relatively high expectations in charging interval restriction aspect is difficult to promote because of the defective that has short time charging apace makes the storage battery dedicated use of electric automobile.
Three, the production process of existing internal storage battery fixed electrode is too complicated.Its production process can't realize automation, still rests on the manual stage as the present technology of the installation of battery terminal, and the electrode of each battery is all installed in later process, not only complicated production capacity of technology but also low and contaminated environment.
Four, the pole plate heaviness and the volume of existing storage battery are bigger than normal.Owing to will prolong the useful life of battery electrode as much as possible, that often battery pole plates is done is thick as far as possible big, and the result is that the battery product under this pattern is all bigger than normal than heaviness and volume relatively.
Five, electrode life and service efficiency can not guarantee.Because the production standard of manufacturing enterprise differs, the environment for use of the battery product of being produced requires different, does not cause export license because of improper use makes the work of battery in the service area, thereby can make the greatly shortening of the useful life of battery than designing requirement.
Six, existing storage battery is difficult to adapt to the marketization of electric automobile.The use of electric automobile be unable to do without this necessary condition that in time charges the battery easily, batteries of electric automobile under the prior art is long owing to the charging interval, do not meet and obtain in time that electric power energy replenishes and the requirement that makes the convenient use of electric automobile, make using and universal can not the popularization of electric automobile, the development of ev industry is hindered.
