| 1. A bipolar high power battery, comprising:
a) at least one group of n stackable electrochemical energy storage cells, connected in series, the cells having:
a lithium ion insertion cathode on a current collector substrate and a lithium ion insertion anode on a current collector
substrate, with an anode-to-cathode capacity ratio r;
a separator material associated between the anode and the cathode; and
an electrolyte system;
wherein 2≤n≤50 and 0.6≤r<1;
b) a leak-proof seal structure;
c) means for voltage monitoring of subgroups of m storage cells connected in series where 2≤m≤10 and m≤n; and
d) means for keeping the battery under compression.
