Definitions
- the invention relates to methods and anodes for improving the power density of lithium secondary batteries, in particular those with solid polymer solutions.
- the current density of the electrolytes is expressed as:
- L E is the conductivity of the electrolyte solution
- ⁇ ⁇ is the potential difference between the anode and cathode material
- tj r is the reduced transport size of the transport species “i”
- ⁇ ⁇ i is the difference in the chemical potential of the species “i” between the anodes - and cathode material.
- boric acid esters and / or boric acid ester derivatives or their compounds are added as additives to improve the power density of lithium secondary batteries, in particular those with solid polymer solutions
- boric acid esters and / or boric acid ester derivatives are used as lithium compounds in complexes of the formula
- R 1 and R 2 can be aromatic and / or aliphatic and in formula III M is a transition metal and the cyclopetadienyl groups can also carry fluorine instead of H.
- Transition metals are elements whose atoms have an incomplete d-shell or which can form one or more cations with incomplete d-shells 21 - 30 in the 5th period Y to Cd (39-48), in the 6th period La to Hg including the lanthanoids, in which the 4f shell is filled (atomic numbers 57-80) and in the 7th period Ac, the actinides to Lr (89-103) Boric acid esters are preferably used
- the residual groups cause electrochemical stability and solubility in the organic solvent. Due to the large and voluminous residual groups, the negative charge is distributed. As a result, it is very unlikely that lithium + will form ion pairs or complex species.
- the salt is therefore dissolved or dissolved in the organic solvent dissociates
- the additives are preferably added on the anode side
- the additives are added in amounts of> 0 to 20% by weight, preferably 5 to 15% by weight
- the anode according to the invention in particular in lithium ion secondary batteries and those with solid polymer solutions, contains additions of boric acid esters and / or boric acid ester derivatives or their compounds at the anode
- the anode consists of a substance that can store lithium ions and / or lithium and conductive salts that are dissolved in solvents and / or in polymer binders and / or a conductive carbon black and / or the additive.
- Such anodes are particularly suitable, the lithiated boric acid ester and / or boric acid ester derivatives in the form of complex compounds of the formulas
- the additives are expediently contained in the anodes in amounts of greater than 0 to 20% by weight, preferably 5 to 15% by weight
- Figure 1 is a schematic sectional view of a battery, for example a lithium ion battery LiC / PEO, lithium salt / Li Mn 2 0 $ without salt, with very low electrical currents in a very short time (idealized case)
- Figure 2 is a schematic sectional view of the same system, in the difference for Figure 1, the graphs show the behavior when using larger currents
- FIG. 3 is again a schematic sectional view of the same system, the graphs show the behavior with small and large currents, there is no salt emptying
- FIG. 4 trends in the curve representations for small, medium and large currents
- FIG. 5 curve representation as in FIG. 4, but ideally with immobilized anions
- FIG. 6 shows schematic exemplary representations of how the cycle strength can be increased on the basis of the use case of polyethylene oxide (PEO)
- FIG. 7 shows the positive derivation of 1 Ohm's law achieved using the additive substances in comparison to the curve profile without positive derivation
- Figure 8 is a schematic representation of anodes / electrolyte / cathodes for the application of the additives and without their use
- FIG. 2 shows the conditions for larger currents in the same system of a lithium ion battery used as an example, local drainage of the seeds occurs. Due to the existence of a mass balance of the lithium ions, their concentration is approximately constant (A)
- the anions move towards the electrolyte against the positive electrode. Since no anions are supplied from the electrodes, a concentration gradient is created (B) According to Kohlrausch's law, the ion conductivity depends on the electrolyte concentration. If the concentration decreases, the conductivity also decreases If a concentration gradient occurs, a gradient of the conductivity arises (C) If the electrolyte conductivity decreases, the local electrolyte resistance increases With an increase in the local electrolyte resistance, a potential drop occurs (D)
- the ideal case shown in FIG. 5 with immobilized anions will be explained in more detail below by way of example.
- the anions are not mechanically immobilized, but their transport size is very small in relation to lithium If the anions are mechanically immobilized, the complex constant is very large, the order of magnitude of the lithium transport decreases. The overall conductivity decreases because the complex constant between the anions and lithium is large
- FIG. 6 is based on the state that if a larger current is required, a high potential must be used. High potentials give only small numbers of cycles or only a limited cycle stability. This is shown in FIG. 6 using the example of the PEO solvent
- FIG. 6 shows the achievement of retained currents according to the invention with then reduced potentials which are of the order of magnitude where the PEO solvent is stable.
- the cycle ability could be increased by using the substances according to the invention above the reduced potentials thus achieved but the constant current achieved.
- the reduced potential increases the number of cycles or the cycle strength
- the invention achieved particularly advantageously that when the substances according to the invention were added to the electrolyte binder material in the anode, the potential, as exemplified in FIG. 6, could be reduced, without reducing the current density
- FIG. 7 shows schematically the so-called positive derivatives of First Ohm's law achieved in addition to the graph of the normal course of First Ohm's law for ordinary batteries in lithium ion battery systems described
- the potential for the investigations was determined to be constant.
- the additive complexes or the substances found were added, and a positive derivation of the first Ohm's law was found.This means a larger current compared to the normally achievable course according to the first Ohm's law
- the measurements were carried out in a lithium half-cell with an active area of approximately 1 cm 2 (standard electrolyte LP 30 EC DMC (1 1), 1 m L ⁇ PF 6 , feed rate 0.1 mV / s)
