BU-403: Charging Lead Acid
Hi, Since you are controlling the charging manually you want to charge to 14.6 or so for a limited time and at a limited current. I have a 350AH flooded cell that I charge at 10 A. At 14.6 it levels off to about 5A, and I …

What''s the Best Battery?
Limited discharge current — although a NiMH battery is capable of delivering high discharge currents, repeated discharges with high load currents reduces the battery''s cycle life. Best results are achieved with load currents of 0.2C to 0.5C (one-fifth to one-half of the rated capacity).

Colossal Capacity Loss during Calendar Aging of Zn Battery …
Importantly, this continuous and rapid aging behavior, whether at low (1 mA cm –2) or high current density (10 mA cm –2), is completely distinct from all other Li-based battery chemistries, as the capacity loss during aging in Li-ion anodes (i.e., graphite, Si, Li metal) levels off as the SEI layer becomes more passivating as it thickens ...
Operational intra-cycle temporal and current mode effects on battery ...
Again, following procedures from Ref. [1], a set of experiments were performed on 2.2 Ah 18650 LiNMC cells which were long term cycling experiments that considered all four permutations of battery cycles composed of high and low current levels for either of the discharge or recharge portions of a given cycle.To enable steady cycling …

The main capacity loss occurred at the anode, with lithium deposits detected after storage at higher temperatures. The performance of LCO and NCA …
Understanding the limitations of lithium ion batteries at high rates
The high rate current pulse tests used a Maccor 4000 unit, with limits of - 2 V to +8 V, and ±5 A. For the graphite and graphite + silicon anodes, the voltage limits used were 0.005–1.5 V. The cathodes used 2.5–4.2 V, with a CC-CV charge protocol, apart from the A123 M1A cathode.

Aircraft batteries: current trend towards more electric aircraft
Batteries that combine high energy density (more than 100 Wh/kg), high charge/discharge cycles (more than 1000) and low cost are difficult to find. Much research has been done to increase the energy density [22-24], but such efforts typically results in cost increase.], but such efforts typically results in cost increase.

Lithium-ion battery modeling under high-frequency ripple current …
This indicates that the high frequency ripple current does not affect the parameters of the first order RC equivalent circuit model. The reason is that the high-frequency current component''s effect on the lithium-ion''s electrochemical reaction can be neglected [12].
