Experimental data simulating lithium battery charging and discharging tests under different external constraint pressure conditions

In this paper, the GSP655060Fe soft pack lithium-ion battery with a capacity of 1600 mAh is utilized, employing lithium iron phosphate as the positive electrode and graphite as the negative electrode. In order to comprehensively evaluate the performance of lithium batteries under the conditions of multi-application scenarios, the operating conditions of the battery were simulated under various external confinement pressures of 300 N, 400 N, 500 N, and 600 N, respectively, and the ambient temperatures of 10 ℃, 25 ℃, and 40 ℃, respectively, were controlled to thoroughly test the battery. One charge/discharge test was conducted on six batteries of the same model at multiplicities of 0.5 C, 1 C, 1.5 C, and 2 C, respectively. To ensure the accuracy and reliability of the experimental data, a Battery comprehensive tester Neware BTS-5V12A was utilized, which possesses high-precision voltage and current measurement capabilities with an error rate of only 0.05 %. This data plays an important role in battery research and development, new energy vehicles, electronic products, and other fields.
