The Maximum Power Transfer Theorem says that you will get maximum power when R L = R S so that would be 0.12 Ω load. The current would be reduced to 1.5/0.24 = 6.25 A and the power into the load (and dissipated in the battery) would be P = VI = 0.75 × 6.25 = 4.7 W.

For example, if we use 10-gauge aluminum THHN wires at an ambient temperature of 50⁰C, then their maximum current should be corrected by 0.82. Thus, the maximum current should be 28.7 amps (35 amps times 0.82). Conclusion. An aluminum wire ampacity chart can help you decide which wire you can use based on temperature.

Aluminium-ion batteries are a class of rechargeable battery in which aluminium ions serve as charge carriers. Aluminium can exchange three electrons per ion. This means that insertion of one Al is equivalent to three Li ions. Thus, since the ionic radii of Al (0.54 Å) and Li (0.76 Å) are similar, significantly higher numbers of electrons and Al ions can be accepted by cathodes with little damage. Al has 50 times (23.5 megawatt-hours m the energy density of Li and is even higher th
If you "forget about" internal resistance, then the maximum current is infinite. An "ideal" component, non-existent in the real world, can provide mathematically "pure" infinite or zero amounts of resistance, voltage, current, and all the rest. Different battery compositions will have different amounts of real-world "impure" limitations

Currently, besides the trivalent aluminum ion, the alkali metals such as sodium and potassium (Elia et al., 2016) and several other mobile ions such as bivalent calcium and magnesium are of high relevance for secondary post-lithium high-valent ion batteries (Nestler et al., 2019a).A recent review by Canepa et al. (2016) states that most of the research on high
Aluminum is a promising anode material in the development of aluminum-ion batteries that may be an alternative to lithium-ion batteries. Aluminum has a low atomic weight (26.98 g/mol) that is still higher than lithium (6.941 g/mol), but aluminum''s trivalence compared to lithium''s single valence electron allows aluminum-ion batteries to have a
Fig. 3 shows the effect of electrolyte temperature at the AAB cell inlet (T in) on the discharge current, maximum current density, electric power, and maximum surface electric power density. The potential difference of the AAB cell was measured with a DC loader as an increasing discharge current from 0.1 A to 7.0 A at steps of 0.1 A. The electrolyte temperature
• Maximum 30-sec Discharge Pulse Current –The maximum current at which the battery can be discharged for pulses of up to 30 seconds. This limit is usually defined by the battery manufacturer in order to prevent excessive discharge rates that would damage the battery or reduce its capacity.

The specific experimental steps are as follows: ① The constructed aluminum-air battery is placed in a constant temperature chamber with target temperatures of 10 °C, 20 °C and 30 °C. ②Discharging an aluminum-air battery to 0.3 V at a constant current of 0.05 A using the Battery Test System. ③ Collecting experimental data such as capacity and voltage of
If a battery is specified to deliver 9 amps, and you limit current to nine amps, the battery will likely achieve lifetime performance reasonably similar to what is specified in the datahseet. Going beyond the rated current may not cause immediate failure, but is likely to adversely affect device lifetime. Trying to draw e.g. 10 amps from a 9

It can supply 1.5 V, but I don't see any information about the current (in A) or the power (in W). Where can I find this information? You should look in the datasheet of that AA battery and check the discharge curves. That gives you an indication. Note that the highest discharge current that is mentioned is 1000 mA = 1 A.
The possible concept of a rechargeable aluminum/aluminum-ion battery based on a low-cost, earth-abundant Al anode, ionic liquid EMImCl:AlCl3 (1-ethyl-3-methyl imidazolium chloroaluminate) electrolytes, and an MnO 2 cathode has been proposed. The Al anode has been reported to show good reversibility in acidic EMImCl:AlCl 3 melts.
Developing high-capacity batteries with high-rate performance has been a challenge. Here, the authors use a liquid metal alloy as anode in the aluminum-ion battery to push the boundaries, enabling the discovery of new roles of electric double layers in facilitating a high-rate charge transfer.
