Summary Lithium‐ion batteries are widely used in the market, and are continuously improving, given their numerous benefits. Choosing the best materials for the cathode is fundamental for optimal battery pack projects. Lithium batteries using nickel cobalt aluminum and nickel manganese cobalt have technology that is already well consolidated within the market. However, some state‐of‐the‐art research describes important technological advances in lithium‐ion stores with lithium iron phosphate oxide and lithium titanate oxide. These have numerous advantages that can improve electric vehicle performance. Different battery technologies were analyzed in this paper, providing a guideline for lithium‐ion battery manufacturers. Previous evaluations on niobium batteries are also presented, analyzing comparative perspectives with lithium‐ion batteries. Advances in cutting edge knowledge show that niobium is a promising metal for use in lithium‐ion batteries. Niobium‐doped batteries have shown good conductivity at low temperatures and high energy density compared with other lithium‐ion storage systems. This study encourages researchers to further develop research on lithium‐ion batteries using a comparative study.

“…Moreover, high temperatures will accelerate the chemical reaction of batteries and further increase the temperature, resulting in thermal runaway [6,7,8]. Circuit operation under high power conditions can not only affect robustness and long-term reliability of circuits [9,10], but also cause batteries to explode. Therefore, thermal protection functionality is critical for power electronics [11,12], such as low dropout regulators [13,14] or switching regulators [15,16,17].…”

This paper presents a novel thermal protection circuit for low dropout regulators (LDOs). To avoid thermal damage under high power conditions, the output current of LDOs varies with the sensed load temperature. Both the current delivery capability at a pre-set temperature and the limit slope of load current can be tuned to accommodate different load conditions and temperatures. The proposed design was fabricated with a 0.18 µm CMOS process with a chip area of 0.073 mm2. Chip measurement results show that the proposed design reduces charging time by 18% over the conventional thermal shutdown structure.
