摘要:
Provided are a cathode active material having a suitable particle size and high uniformity, and a nickel composite hydroxide as a precursor of the cathode active material. When obtaining nickel composite hydroxide by a crystallization reaction, nucleation is performed by controlling a nucleation aqueous solution that includes a metal compound, which includes nickel, and an ammonium ion donor so that the pH value at a standard solution temperature of 25° C. becomes 12.0 to 14.0, after which, particles are grown by controlling a particle growth aqueous solution that includes the formed nuclei so that the pH value at a standard solution temperature of 25° C. becomes 10.5 to 12.0, and so that the pH value is lower than the pH value during nucleation. The crystallization reaction is performed in a non-oxidizing atmosphere at least in a range after the processing time exceeds at least 40% of the total time of the particle growth process from the start of the particle growth process where the oxygen concentration is 1 volume % or less, and with controlling an agitation power requirement per unit volume into a range of 0.5 kW/m3 to 4 kW/m3 at least during the nucleation process.

摘要:
A battery capacity controller includes a battery capacity estimating part that estimates the battery capacity of a battery in which an internal resistance is increased in accordance with the decrease of the battery capacity in the vicinity of a prescribed lower limit battery capacity and a battery capacity correcting part that changes, during the discharge of the battery, an estimated battery capacity estimated by the battery capacity estimating part to a proper value in a lower limit side when an internal resistance difference as a difference between the internal resistance value of the battery and the internal resistance value of the battery at the time of the lower limit battery capacity is a prescribed value or lower.
摘要:
A static casting mold for hollow cast product with bottom comprising a top lid, a core and an outer mold section, the core being attached to the top lid and disposed inside the outer mold section. The outer mold section includes a lateral mold section and a lower mold section. The lateral mold section is formed at its inner peripheral wall portion with a composite cooling section by stacking chiller blocks and interposing therebetween refractory sands and at its outer wall portion with refractory sands. Cooling pipes includes a first and second pipes. A first pipe extends longitudinally through the refractory sands at the outer wall portion and a second pipe extends longitudinally through the inner wall portion in contact with at least a part of each of the chiller blocks, the first and second pipes being connected at their lower portions through the bend portion. The chiller blocks are cooled by water flowing in the second pipes.

A front fender panel and an apron upper member are connected via an impact absorbing bracket. The impact absorbing bracket has a first supporting leg portion and a second supporting leg portion that form an angle with one another as seen from a vehicle vertical direction. The first supporting leg portion and the second supporting leg portion are connected, via a connecting portion, further toward a vehicle lower side than a fender panel mounting portion.

A bumper structure, that can mitigate impact when a collision body collides with a vehicle transverse direction end portion of an impact absorbing member, is obtained. A bumper structure has a bumper reinforcement that extends along a vehicle transverse direction at a vehicle front-rear direction end portion; an impact absorbing member that is provided at a vehicle front-rear direction outer side of this bumper reinforcement, and at which an outer side surface of a vehicle transverse direction end portion is made to be an inclined surface that is inclined toward a vehicle transverse direction outer side, from a vehicle front-rear direction outer side toward a vehicle front-rear direction inner side; and a plate-shaped member that is provided along the inclined surface, and whose rigidity is higher than the impact absorbing member.
