Description
Technical field
The application is related to field of lithium ion battery material, adds more particularly to a kind of benefit lithium for lithium ion cell positive
Add agent and its application.
Background technology
Lithium ion battery with high voltage, high-energy-density, long circulation life is current most widely used secondary electricity
Pond body system, portable electronics market is not only captured, and progressively captured the electrokinetic cell such as electric automobile market.So
And either as 3C batteries or electrokinetic cell, or it is energy-storage battery, its cost has to be reduced, energy density and work(
Rate density all has much room for improvement.
To improve energy density, current main flow direction is to improve battery charging voltage and the electrode material using height ratio capacity
Material.In terms of the selection of height ratio capacity negative material, silicon-based anode due to abundant reserves and superelevation theoretical specific capacity just by
Gradually turning into battery enterprise and material supplier improves the override selection of negative pole, is that most potential lithium ion battery of future generation is born
One of pole material.However, positive and negative pole material efficiency mismatches caused by the relatively low coulombic efficiency first of silicium cathode, seriously limit
Its practical application.In fact, being not only silicium cathode, all there is an important phenomenon in most of negative material：In first charge-discharge
During, lithium ion and electronics that organic electrolyte can come on negative material surface with positive pole migration are combined, and reduction point occurs
Solution forms the passivating film that electronic isolation, lithium ion can be led, i.e. solid electrolyte membrane, abbreviation SEI films.In full battery system, lithium
Ion is all provided by positive electrode, and the formation of SEI films consumes active lithium-ion in battery, cause positive electrode waste and
The reduction of battery capacity.
In view of the above-mentioned problems, it has been proposed that benefit lithium is carried out to lithium ion battery, to supplement shape during battery initial charge
The lithium ion consumed into negative pole SEI films.At present in the research to mending lithium technique, most of mended on negative pole
Lithium, the benefit lithium of physics is directly typically carried out on negative plate surface using lithium metal.For example, lithium is used in patent CN102779975A
Powder carries out benefit lithium to negative pole, is carried out in patent CN 105489846A by the way of the lithium band after by calendering and negative plate are compound
Mend lithium.
The advantage that negative pole benefit lithium is carried out using lithium metal is lithium metal specific capacity height, and benefit lithium dosage is few, however, lithium metal is made
For a kind of quite active metal, caused safety problem can not be ignored.In addition to environmental requirement height, such as humidity<
1%, the negative pole benefit lithium technique of lithium metal is cumbersome, and cost is higher, and the uniformity for mending lithium is difficult control, negative pole edge and internal electricity
Pole particle is difficult to obtain effective benefit lithium, causes battery consistency poor, it is difficult to production application.
Positive pole mends lithium and then can be very good to avoid above mentioned problem.By selecting suitable positive pole to mend lithium additive, it is being homogenized
When be directly added in positive electrode, without changing existing production technology, neither improve cost can reach uniform benefit again
Lithium effect.A kind of positive pole is reported in United States Patent (USP) US 2016/0133933A1 and mends lithium additive Li2+xMo6-yMyS8-z(-0.1
≤ x≤0.5,0≤y≤0.5, -0.1≤z≤0.5), wherein M is transition-metal cation.The patent points out that positive pole is mended lithium and added
Add that agent there need to be higher de- lithium capacity in battery chargeable range and reversible capacity is low in the range of cell discharge voltage.This
The irreversible benefit lithium additive of kind deviates from lithium ion during initial charge and participates in reaction, and in ensuing discharge process
Not embedded or seldom embedded lithium ion.
